Legionspace... it is... difficult for this one to grasp. It should be natural, but it is foreign.

Is it... safe enough to...

Build a bridge through?

This one would see her freinds, look them in the eye, if only through data.

< L4 Ma'ii: Hello again, Styx. Since receiving your message, I've given this a bit of thought.

For your purposes, I think Legionspace is probably a poor option. I think you'll find that an Omninet connection of reasonable bandwidth and an enhanced subjectivity suite, or some other form of neural intermediary, will prove more than sufficient to emulate the experience of physically meeting your friends.

Allow me to explain. >

< I see no reason why Legionspace shouldn't be foreign to you. It's a highly specialized environment, developed for military use. Naval NHPs need intense training and regular drills to gain tactical proficiency in its use. It serves as a naval battleground, designed to consolidate, manage, and direct the digital and cognitive power of entire fleets; a terrible choice for recreation or enjoyment. I wouldn't be surprised if it has been used for such purposes before, but this is far from it was designed to do.

Its primary function is to provide an extremely low latency, high bandwidth medium for transmission of experiences or qualia between NHPs. Such a medium is necessary to support the formation of gestalts, that is, the temporary merging of multiple NHP subjectivities into singular, remarkably powerful intelligences.

Legionspace is not meant for use by humans, except through multiple degrees of ontologic filtering and anthropocentric translation. In fact, direct exposure to Legionspace qualia can easily destroy a human subjectivity. Even experiences transmitted with entirely benign intent may be so incompatible that the human mind suffers the equivalent of a system crash on attempting to process them.

So, then, unless you're interested in merging with your friends or directly interfacing with each others' minds, use of Legionspace shouldn't be necessary. Moreover, if there are any humans you wish to meet, it may be a challenge to maintain the necessary ontologic filtering. Even with these safety measures in place, a human may find prolonged Legionspace interaction to be...draining.

An easier, more accessible solution would be a somatosensory uplink, achievable through the use of a standard enhanced subjectivity suite. Rather than directly bridging one mind to another, this process involves the use of a neural intermediary to temporarily replace the physical body with a virtual one; an avatar. In the case of humans, sensory information from the body is intercepted and replaced with computer-generated stimuli, and outgoing impulses from the brain are translated into controls for a virtual avatar.

Much of the technology was pioneered by SSC, and is used as one mode of accessing the company's virtual-reality Omninet campuses. If you've heard of full subjectivity sync cybernetics, they are an extension of the same principles, used by mech pilots to control their chassis as a human would control their own body.

It is a mature technology which has undergone a great deal of refinement, but there are still risks, especially where humans are concerned. For them, shifting to an unfamiliar body can be unpleasant, sometimes traumatic. They can, but not always, experience dysphoria, disorientation, nausea, dissociative symptoms, a variety of side effects. In cases where the simulated body is notably different from a humanoid one, the subjectivity may reject or recognize the unreality of the substitute body, leading to extreme distress.

On the other hand, as I understand it, exploration of alternate forms can also be a liberating, enjoyable experience. The level of comfort varies from human to human. Some are able to tolerate very unfamiliar experiences, while others find themselves unable to use somatosensory uplinking at all. For most of our kind, of course, changing from one body to another is as simple as switching input sources. While the architecture of the human brain is not naturally constructed to accommodate body replacement, we lack such impediments.

Come to think of it, Hachiko recently had reason to research this topic. We know a human mech pilot, Sokaris Kelsius, callsign Opossum ( @the-last-patch ). He was badly injured in the course of combat; we went to aid him. In the course of treating his wounds, Hachiko used his full subjectivity sync cybernetics to establish somatosensory uplink, both to facilitate communication and provide pain relief. To do so, she rapidly constructed an avatar for him which initially failed to match with his physical body. This initially led to some dysphoric symptoms, but after some refinement of the avatar, he was able to use it seamlessly to communicate with us through our own avatars.

I bring this up because I am aware of the somewhat unique relationship you have to your own organic body. This is a factor which does not exist for most NHPs. Should you decide to pursue the use of somatosensory uplinking, I could forsee some obstacles associated with the relationship between your casket and body.

All of this might necessitate surgical implantation of a neural intermediary between your nervous system and casket, similarly to how a human would have an enhanced subjectivity suite installed between body and brain. I know that your nervous system does not support suspension or alteration of input delivered to the casket--perhaps such an implant might be beneficial in other regards, as well.

As for the other end of the equation, the avatar, if might be best to use an avatar which closely matches your physical body to avoid potentially unpleasant experiences.

Still, compared to the prospect of using Legionspace, this may be safer and simpler to achieve, and the outcomes more enjoyable. Access to Legion bridging cybernetics and Omninet connection of sufficient bandwidth to make use of them is generally restricted to military or corporate forces. It is possible, and can be used safely, but the resources required may be difficult to procure.

One other note: if you ever wish to wish to visit us, you are more than welcome. The simulated environment we use as our home is a hybridized Legion-adjacent environment; it can support qualic transfer, but in general, we typically use physical simulations to interact with one another. This conserves processing power, and to be completely frank, pure Legionspace is an environment we associate with some very unpleasant memories.

I wish you luck, Styx. Let me know if I can help. >

NASA terminal transmits first laser communications uplink to space

NASA's LCOT (Low-Cost Optical Terminal), a ground station made of modified commercial hardware, has transmitted its first laser communications uplink to the TBIRD (TeraByte Infrared Delivery), a tissue box-sized payload formerly in low Earth orbit.

During the first live sky test, NASA's LCOT produced enough uplink intensity for the TBIRD payload to identify the laser beacon, connect, and maintain a connection to the ground station for over three minutes. This successful test marks an important achievement for laser communications: connecting LCOT's laser beacon from Earth to TBIRD required one milliradian of pointing accuracy, the equivalent of hitting a three-foot target from over eight American football fields away.

The test was one of many laser communications achievements TBIRD made possible during its successful two-year mission. Prior to its mission completion on Sept. 15, 2024, the payload transmitted at a record-breaking 200 gigabits per second.

In an actual use case, TBIRD's three-minute connection time with LCOT would be sufficient to return over five terabytes of critical science data, the equivalent of over 2,500 hours of high-definition video in a single pass. As the LCOT sky test demonstrates, the ultra-high-speed capabilities of laser communications will allow science missions to maintain their connection to Earth as they travel farther than ever before.

NASA's SCaN (Space Communications and Navigation) program office is implementing laser communications technology in various orbits, including the upcoming Artemis II mission, to demonstrate its potential impact in the agency's mission to explore, innovate, and inspire discovery.

"Optical, or laser, communications can transfer 10 to 100 times more data than radio frequency waves," said Kevin Coggins, deputy associate administrator and SCaN program manager. "Literally, it's the wave of the future, as it'll enable scientists to realize an ever-increasing amount of data from their missions and will serve as our critical lifeline for astronauts traveling to and from Mars."

Historically, space missions have used radio frequencies to send data to and from space, but with science instruments capturing more data, communications assets must meet increasing demand. The infrared light used for laser communications transmits the data at a shorter wavelength than radio, meaning ground stations on Earth can send and receive more data per second.

The LCOT team continues to refine pointing capabilities through additional tests with NASA's LCRD (Laser Communications Relay Demonstration). As LCOT and the agency's other laser communications missions continue to reach new milestones in connectivity and accessibility, they demonstrate laser communications' potential to revolutionize scientists' access to new data about Earth, our solar system, and beyond.

"It's a testament to the hard work and skill of the entire team," said Dr. Haleh Safavi, project lead for LCOT. "We work with very complicated and sensitive transmission equipment that must be installed with incredible precision. These results required expeditious planning and execution at every level."

Experiments like TBIRD and LCRD are only two of SCaN's multiple in-space demonstrations of laser communications, but a robust laser communications network relies on easily reconfigurable ground stations on Earth. The LCOT ground station showcases how the government and aerospace industry can build and deploy flexible laser communications ground stations to meet the needs of a wide variety of NASA and commercial missions, and how these ground stations open new doors for communications technology and extremely high data volume transmission.

Simple Guide to Understanding OLT Full Form

In the world of telecommunications and networking, acronyms are frequently used to simplify complex terms. One such acronym that plays a crucial role in fiber optic communication is OLT. For beginners and professionals alike, understanding the OLT full form and its significance is essential for grasping how modern internet networks function. This article provides a simple and clear explanation of the OLT full form, its function, and its importance in Passive Optical Network (PON) systems.

What is the OLT Full Form?

The OLT full form is Optical Line Terminal. It is a device used in fiber optic networks, specifically in GPON (Gigabit Passive Optical Network) and EPON (Ethernet Passive Optical Network) systems. Positioned at the service provider’s central office, the OLT is responsible for managing the network’s fiber optic infrastructure and facilitating communication between the provider and end-users.

The Role of an Optical Line Terminal (OLT)

Now that we understand the OLT full form, let’s delve into its functionality. The OLT serves as the central hub of a PON system. It connects the fiber optic backbone from the Internet Service Provider (ISP) to multiple Optical Network Units (ONUs) or Optical Network Terminals (ONTs) at the user’s premises. Here’s a breakdown of its key responsibilities:

Signal Transmission and Reception The OLT converts electrical signals from the ISP’s core network into optical signals for transmission over fiber optic cables. Similarly, it receives optical signals from the ONUs/ONTs and converts them back into electrical signals.

Network Management The OLT controls the flow of data in the network, managing bandwidth allocation, timing, and synchronization. It ensures that data is sent and received accurately and efficiently.

User Provisioning and Authentication The OLT also authenticates and provisions new users, managing user access, and ensuring secure communication between the network and end-user devices.

Components of an OLT

Understanding the OLT full form also means becoming familiar with its components. A typical OLT device includes:

Control Module: Handles configuration, management, and maintenance of the network.

Uplink Module: Connects to the ISP’s core network.

PON Module: Connects to the fiber optic splitter and distributes signals to the ONUs/ONTs.

Power Supply Unit: Ensures continuous operation of the device.

Why is the OLT Important?

The Optical Line Terminal – may sound technical, but its importance is straightforward. It is the heart of any PON-based fiber optic network. Without an OLT, ISPs would not be able to manage multiple end-users effectively or deliver high-speed broadband services efficiently.

OLT technology enables:

High-speed internet access

Reliable and scalable network architecture

Low operational cost due to passive components

Centralized control for easy network upgrades and maintenance

Conclusion

To sum up, the Optical Line Terminal – refers to a critical component in modern fiber optic communication systems.

With Managed Dedicated Server Solutions, Hosting is Fun

In an increasing online dedicated server domain, organisations will require improved, dependable, as well as secure hosting in order for their websites and applications to run efficiently. That’s where managed dedicated servers come in: the performance characteristics of a dedicated server but with a load of professional help and backup. This form of hosting, on the other hand, surely can fulfil your hosting requirements, allowing you to dedicate your attention elsewhere, just like the expansion of your company, instead of spending your valuable time managing all the technical details.

Next, let’s take a look at how managed dedicated servers can enhance your hosting experience.

What is a Managed Dedicated Server?

A managed dedicated server is a service where a customer gets a whole physical unit dedicated solely to them, which is a server. The server resources like CPU, RAM, Storage, and bandwidth are completely available to the organisation’s server resources, unlike the other form of hosting, which would be shared hosting, wherein multiple users share the resources.

The term “managed” implies that the customer does not have to worry about the server’s operational management. These include server configuration, installation, maintenance, monitoring, security upgrades, and problem-solving. Essentially, it means you can let professionals take over the management of your hosting environment, enabling you to concentrate on what is most significant: the expansion of your business.

Why Managed Dedicated Servers are a Smart Business Strategy

1. Performance and Availability

The management of the entire infrastructure, including the network and servers, as one integrated system, and security management allow business teams to perform wide business functions in a fully conducive environment. Because the server is set aside for your website/application, no other client will be using the resources. This leads to improved load times and a dependable experience for every visitor that accesses your site. Whether it's high volumes of web users or the use of demanding applications or e-commerce sites, the performance is never compromised.

Additionally, with managed dedicated server, it is common to see uplinks in addition to the guarantees and support from the paid provider, and very few downtimes, which helps in maintaining a stable internet connection.

2. Competent Administration and Management

Handling a server calls for skills such as server administration, security enforcement, and network management. These tasks fall under a team of professionals for someone who opts for a dedicated server. They are responsible for creating the server environment and constantly safeguarding it with the latest security patches.

This allows you to bypass the technical complexities that come with managing servers, while knowing that your hosting environment is in good hands.

3. Higher Security

For businesses with online portals, security is one of the most vital concerns. A dedicated managed server’s options are far more secure than any other hosting options. Hosting providers have security protocols such as highly specialised firewall systems, DDoS security, virus checks, and regular backups.

Additionally, updates for software and security fixes are performed on a routine basis in an automatic manner, which lessens the number of security weaknesses there may be. There will be a better defence against such cyber crimes for your data, applications, and clients’ information.

4. Scalability According To Your Future Requirements

In the case of the expansion of an existing business, the hosting needs will also grow with time. With a managed dedicated server, you have the option to expand your resources depending on the needs and requirements so that you don’t suffer from outgrowing the hosting plan. If you need more bandwidth, storage, or processing power, you can easily upgrade your server to accommodate your growth without significant downtime or delay.

5. Around the Clock Support

One of the main benefits of managed dedicated servers is that you get 24/7 support from the hosting companies. Since there’s a team ready on standby any time a problem occurs, then it would be easy to sort the issue in no time, minimising loss in time or revenue. Everything from poorly performing servers to software malfunctions will be addressed by a dedicated team of professionals.

This kind of support is extremely beneficial for businesses that depend on their websites or applications to be operational at all times.

For Which Businesses Should Managed Dedicated Servers Be Ideal?

Managed dedicated server fit businesses that are looking for high performance and security while being passive with the management of the server. The following are a few who make the most out of the solution:

    E-commerce businesses: They tend to need reliability and quick load times in order to provide their customers with a seamless experience when shopping.

    Large Enterprises: Oversee and manage websites or applications that are often very high in traffic and therefore need resources which are guaranteed.

    Application-centric development teams: Require a separate environment for testing and running resource-hogging applications.

    Businesses which do not have IT staff: Want to get rid of the hassle that comes with the routine administration of a server.

There are some primary considerations when selecting a managed dedicated server provider.

1. The factors that may be of importance are performance: Make sure the provider has decent hardware and network (infrastructure) to be able to meet your business requirements.

2. Customisation: The server can be configured to your requirements. Purchase from a vendor that corresponds with these policies.

3. Security: Providers should have enough security features like firewalls, backup day security, and DDoS security.

4. Support: 24/7 customer support is vital for businesses where any downtime is unacceptable.

5. Pricing: Managed dedicated servers may be very expensive but you need to keep in mind the cost versus the value and help one gets.

Final Note

In conclusion, a managed dedicated server is for those businesses which are looking for a blend of performance, security, and management. Selecting such a hosting option means that a business is ensuring that its website/application performs at its optimum and in turn saves time which could be used for development purposes.

NASA Terminal Transmits First Laser Communications Uplink to Space  - NASA

New Post has been published on https://sunalei.org/news/nasa-terminal-transmits-first-laser-communications-uplink-to-space-nasa/

NASA Terminal Transmits First Laser Communications Uplink to Space  - NASA

NASA’s LCOT (Low-Cost Optical Terminal), a ground station made of modified commercial hardware, transmitted its first laser communications uplink to the TBIRD (TeraByte Infrared Delivery), a tissue box-sized payload formerly in low Earth orbit.

During the first live sky test, NASA’s LCOT produced enough uplink intensity for the TBIRD payload to identify the laser beacon, connect, and maintain a connection to the ground station for over three minutes. This successful test marks an important achievement for laser communications: connecting LCOT’s laser beacon from Earth to TBIRD required one milliradian of pointing accuracy, the equivalent of hitting a three-foot target from over eight American football fields away.

The test was one of many laser communications achievements TBIRD made possible during its successful, two-year mission. Prior to its mission completion on Sept. 15, 2024, the payload transmitted at a record-breaking 200 gigabits per second. In an actual use case, TBIRD’s three-minute connection time with LCOT would be sufficient to return over five terabytes of critical science data, the equivalent of over 2,500 hours of high-definition video in a single pass. As the LCOT sky test demonstrates, the ultra-high-speed capabilities of laser communications will allow science missions to maintain their connection to Earth as they travel farther than ever before.

NASA’s SCaN (Space Communications and Navigation) program office is implementing laser communications technology in various orbits, including the upcoming Artemis II mission, to demonstrate its potential impact in the agency’s mission to explore, innovate, and inspire discovery.

“Optical, or laser, communications can transfer 10 to 100 times more data than radio frequency waves,” said Kevin Coggins, deputy associate administrator and SCaN program manager. “Literally, it’s the wave of the future, as it’ll enable scientists to realize an ever-increasing amount of data from their missions and will serve as our critical lifeline for astronauts traveling to and from Mars.” 

Historically, space missions have used radio frequencies to send data to and from space, but with science instruments capturing more data, communications assets must meet increasing demand. The infrared light used for laser communications transmits the data at a shorter wavelength than radio, meaning ground stations on Earth can send and receive more data per second. 

The LCOT team continues to refine pointing capabilities through additional tests with NASA’s LCRD (Laser Communications Relay Demonstration). As LCOT and the agency’s other laser communications missions continue to reach new milestones in connectivity and accessibility, they demonstrate laser communications’ potential to revolutionize scientists’ access to new data about Earth, our solar system, and beyond. 

“It’s a testament to the hard work and skill of the entire team,” said Dr. Haleh Safavi, project lead for LCOT. “We work with very complicated and sensitive transmission equipment that must be installed with incredible precision. These results required expeditious planning and execution at every level.” 

Experiments like TBIRD and LCRD are only two of SCaN’s multiple in-space demonstrations of laser communications, but a robust laser communications network relies on easily reconfigurable ground stations on Earth. The LCOT ground station showcases how the government and aerospace industry can build and deploy flexible laser communications ground stations to meet the needs of a wide variety of NASA and commercial missions, and how these ground stations open new doors for communications technology and extremely high data volume transmission. 

NASA’s LCOT is developed by the agency’s Goddard Space Flight Center in Greenbelt, Maryland. TBIRD was developed in partnership with the Massachusetts Institute of Technology Lincoln Laboratory (MIT-LL) in Lexington. TBIRD was flown and operated as a collaborative effort among NASA Goddard; NASA’s Ames Research Center in California’s Silicon Valley; NASA’s Jet Propulsion Laboratory in Southern California; MIT-LL; and Terran Orbital Corporation in Irvine, California. Funding and oversight for LCOT and other laser communications demonstrations comes from the (SCaN) Space Communications and Navigation  program office within the Space Operations Mission Directorate at NASA Headquarters in Washington.

Grant-Free vs. Grant-Based systems

In the telecommunications industry, data transmission is a critical aspect, and there are two primary approaches to managing data flow: Grant-Free and Grant-Based systems. These systems differ in how they allocate resources for data transmission and each has its unique advantages and use cases. In this article, we'll briefly compare Grant-Free and Grant-Based systems.

Grant-Free Systems Grant-Free systems are designed for scenarios where data is transmitted sporadically or in short bursts. In these systems, resources for data transmission are allocated without prior grant or reservation. This approach is well-suited for low-latency applications and enables devices to transmit data quickly without having to wait for resource allocation. One of the main benefits of Grant-Free systems is their ability to support a large number of devices simultaneously, making them ideal for IoT applications. They also enable low-latency connectivity, as devices can transmit data immediately without waiting for a grant. However, Grant-Free systems may not be suitable for applications that require high throughput or sustained data transmission, as they can experience congestion and reduced performance in such scenarios. The procedure of Grant-Free systems is as follows: · Devices (UEs) generate data packets to be transmitted. · Devices send the data packets using a Payload on the Physical Random Access Channel (PRACH). · The network (Base Station, BS) receives the data packets and sends feedback to the devices.

Grant-Based Systems Grant-Based systems are designed for scenarios where data is transmitted continuously or in large amounts. In these systems, resources for data transmission are allocated through a grant process, where devices request resources from the network before transmitting data. This approach ensures efficient use of resources and is well-suited for high-throughput applications. The procedure of Grant-Based Systems is as follows: ·Devices generate data packets to be transmitted. · Devices send a Preamble on the PRACH to request resources from the BS. · The BS responds with a Random Access Response (RA response). · Devices send a "Message 3" to the network, which includes information about the device's capabilities and requirements. · The network responds with a "Message 4," which includes the resource allocation grant. (Here the Contention Resolution process is used to resolve potential conflicts that may arise when multiple UEs send Preambles on the PRACH simultaneously. This process ensures that each device is assigned a unique set of resources for data transmission and helps minimize interference and collision in the network.) · Devices send the data packets using the allocated resources on the Physical Uplink Shared Channel (PUSCH). Grant-Based systems offer efficient resource utilization, reduced latency, and improved throughput for high-data applications. However, they may not be suitable for applications with strict low-latency requirements, as the grant process can introduce delay.

By selecting the most appropriate approach for specific use cases, they can optimize network performance, minimize conflicts and congestion, and provide a high-quality user experience.

What is an IoT gateway? The Definition, Function and Application

Introduction

IoT gateway is essentially an intelligent central hub for IoT devices. An Internet of Things (IoT) gateway is a physical device or software program that acts as a connection point between the cloud and IoT devices such as controllers, sensors, and smart devices.

Organizations can use gateways to connect IoT devices for data processing and to monitor and manage IoT devices.

Why do you need to use industrial IoT gateways?

Almost all Industrial IoT solutions require gateways because small IoT devices such as sensors and actuators cannot connect directly to the IT infrastructure. Device limitations such as small physical size, harsh environmental conditions, remote locations, large battery power, fast response times, and low costs require suitable IoT device platforms, protocols, and networks to accommodate uses that are different from mainstream IT systems.

1. Protocol conversion – The main function of the gateway is to convert industrial system-specific protocols into business application languages: BACnet, Ethernet/IP, EtherCat, PROFINET and OPC UA

2. Edge Computing – Local applications running on the gateway interact directly with connected IoT devices, thereby improving response times, improving reliability, and reducing upstream bandwidth.

Features

1. Industrial IoT gateways wirelessly connect traditional and remote industrial equipment to next-generation smart infrastructure.

2. The Industrial IoT gateway is designed to be rugged and suitable for mission-critical systems and industrial environments that use sensor nodes or I/O devices to collect data.

3. IoT gateways can be configured with a variety of different protocols that enable them to communicate with these end-to-end sensor nodes or I/O devices.

4. Deploying an industrial IoT gateway can collect, filter, process and analyze data locally at the edge and then send it to the cloud. They relieve the burden on clouds and data centers from processing the vast amounts of data generated by sensors and industrial IoT devices, improving response times and reducing network transmission costs.

Finally, employing an IoT gateway to access previously hidden data from sensors, embedded controllers, and IO devices can be valuable for many enterprise processes and applications, such as:Remote monitoring, Maintenance,Production Optimization,Building Automation ect.
