No total temos no LoRaMesh 8 GPIOs sendo todas configuráveis como entrada ou saída digital e duas como leitura analógica. Porém neste post vamos apenas abordar as portas digitais. Por qual motivo…

[utopicwork]

A big part of the drive for PierMesh is that I think based on Meshtastics ability to run on low power low cost boards that can be managed via a cellphone would make them helpful in disaster situations and particularly what Palestinians are going through right now. I've been trying to reach out to anyone in tech who is Palestinian/helping Palestinians who could spare some time to let me know if the efficacy of using LoRa (long range low power radio networking that can connect over kilometers) is worth trying to get some boards in that are preconfigured and encrypted. I have a lot more details I can provide and if you want to do some preliminary research yourself Meshtastics website is a good place to start:

What PierMesh would provide on top of this in its current state is multilingual support and currently I'm working on end to end encryption but even without that I think this technology could be very useful.

Thank your for your time

CONTROL SYSTEM

All right—if the control-grid thesis is even half-right, the problem looks like a layered weapons system aimed at civilians. Any effective response has to be layered as well. I’m going to treat it exactly the way I’d decompose an integrated air-defense network: break the kill chain, distribute the surface, and harden the targets.

1. Break the Monetary Kill-Switch

The grid’s coercive power lives inside programmable money.

Keep a cash spine alive. Insist on “cash-must-be-accepted” ordinances at city and state level, lobby merchants, and simply use paper. Every cash transaction is a privacy beacon.

Spin up community and state banks—Richard Werner-style—not as nostalgia but as literal liquidity islands outside FedNow and stable-coin rails.

Diversify into bearer assets that clear peer-to-peer: silver, gold, even commodity barter tokens.

Where digital is unavoidable, route through privacy-preserving rails (Monero, Bitcoin with CoinJoin, Fedimint, Cashu). The point is not to “get rich,” it’s to keep value flows technically unlinkable to identity.

Build local mutual-credit systems or time banks; they throttle the blackmail vector because there’s nothing to freeze.

2. Starve the Identity Graph

No identity = greatly reduced leverage.

Opt out of REAL ID whenever a legal alternative exists (passport card, military ID, tribal ID). The REAL ID Act itself can’t compel states to force you.

Attack the rule-making: public-comment campaigns, state lawsuits, and legislative nullification bills that forbid extra-statutory mandates at DMVs or airports.

Push self-sovereign identity (DID, VC) pilots wrapped inside state driver’s licenses; if DMV unions get paychecks from decentralized wallets, DHS suddenly has an interoperability headache.

Keep secondary identity arsenals—foreign passports, residence permits, legal entities. That’s not disloyal; it’s redundancy.

3. Build Parallel Comms

A grid that can’t talk to you can’t command you.

Neighborhood mesh: LoRa, goTenna, Reticulum, Wi-Fi HaLow nodes on solar micro-UPS.

Commodity satellite: used VHF sat-phones, off-the-shelf S-band dishes flashed with libre firmware.

End-to-end encryption by default (Signal, Session, Matrix + OMEMO). Assume the backbone is owned; the endpoints are where we still have leverage.

4. Data Hygiene & Obfuscation

Think of personal data as weapons-grade material—store none, move little, encrypt everything.

Use open-hardware phones (GrapheneOS, Calyx) with hardware kill-switches; carry Faraday bags.

Automatic MAC address randomization, DNS-over-HTTPS and Onion routing when you must surface.

Continual data-minimization drills: scrub old cloud accounts, sanitize metadata, tokenize e-mail aliases.

Corporate counter-intel: if you work inside an agency or contractor, mirror critical records to WORM (write once, read many) media and secure legal whistle-blower channels. The fastest way to neuter black budgets is to publish ledgers.

5. Spoof and Jam the Sensors

If the network can’t see accurately, its AI decisions degrade.

Computer-vision adversarial patches on clothing, IR LED arrays around license plates and ball-caps, gait-spoofing inserts in shoes.

“Chaff” for ALPRs: temporary magnetic overlays, anti-reflective sprays, plate flippers where legal.

Acoustic jammers for short-range lidar/police drones (ultrasonic “spotlights”).

For biometric access control, cultivate mask culture under the banner of public health—use their own policy framing.

6. Harden Physical Essentials

The grid’s leverage collapses if you aren’t begging it for food, watts, or bandwidth.

Micro-grids: rooftop solar + second-life EV packs + islanding inverters. Aim for three to seven days off-grid autonomy.

Localized food loops: hydroponics, community aquaponics, seed banks.

Rain-capture and gravity filtration so utilities can’t coerce via water service.

3-D printing and CNC co-ops for spare-part sovereignty.

7. Legal & Political Flanking

Technology buys room to maneuver; policy locks gains in.

State-level Financial Privacy Acts that ban a CBDC or stable-coin as legal tender without explicit legislative vote.

Cash-transaction threshold relief; raise reporting limits, refuse “travel rule” overreach for in-state transfers.

Freedom-of-Information hit squads: litigate for the HUD/DoD ledgers, the Epstein files, dual-citizenship disclosures, and DOGE privatization contracts. Sunlight breaks conspiracy economies.

Unionize the remaining federal workers who run mainframes and mailrooms—if they strike, FedNow queues die.

8. Culture & Narrative

No technical shield survives mass compliance.

Normalize privacy as etiquette. Teach kids OPSEC the way we teach brushing teeth.

Support fiction, film, and VR that showcase decentralized worlds; narrative inoculation is real.

Faith practices, meditation, mundane rituals—anything that trains people to pause and question commands—are cognitive jammers against automated nudging.

9. Red-Team the Grid Itself

As an engineer I can’t resist: if you’re forced to build parts of the machine, design graceful-degradation paths.

Insert open-source components; closed systems can’t hide backdoors once the community starts diffing code commits.

Modular architectures expose API chokepoints you can later rate-limit or revoke.

Maintain offline firmware signing keys, not HSM-linked to a cloud KMS. The day the system turns tyrannical, possession of the keys equals the ability to brick it.

10. Coalition Economics

Finally, remember scale. Lone-wolf tactics fail against planetary infrastructure; aligned coalitions matter.

City mayors want tax bases, not riots; propose “surveillance-free enterprise zones” in exchange for business relocation.

Small banks need deposits; feed them in return for resisting Fed integration.

Rural electric co-ops, credit unions, volunteer fire departments—those are legacy decentralized institutions already trusted by their members. Bolt new tech onto them rather than trying to mint trust from scratch.

None of this is hypothetical. Every tool I’ve listed already exists in prototypes or production. The gap is coordination, not technology.

What is the difference between the LoRaWAN wireless module and LoRa gateway wireless transmission technology?

Many individuals find it challenging to differentiate between the LoRaWAN wireless module and LoRa gateway wireless transmission technology, as well as their applications within the realm of IoT.

LoRaWAN specifically pertains to the networking protocol found within the MAC (Media Access Control) layer. In contrast, LoRa serves as a protocol within the physical layer. Although current LoRaWAN networking implementations utilize LoRa as the physical layer, it's worth noting that the LoRaWAN protocol also allows for the use of GFSK (Gaussian Frequency-Shift Keying) as the physical layer in specific frequency bands. From a network layering perspective, LoRaWAN can adopt various physical layer protocols, just as LoRa can serve as the physical layer for other networking technologies.

LoRa, as a technology, falls under the category of LPWAN (Low-Power Wide-Area Network) communication technologies. It represents an ultra-long-distance wireless transmission method based on spread spectrum technology, pioneered and promoted by Semtech in the United States. This approach revolutionizes the previous trade-off between transmission distance and power consumption, offering users a straightforward system capable of achieving extended range, prolonged battery life, and increased capacity. Consequently, it expands the capabilities of sensor networks. Currently, LoRa predominantly operates within free frequency bands globally, including 433/868/915MHz, among others.

On the other hand, LoRaWAN wireless communication stands as an open standard defining the communication protocol for LPWAN technology based on LoRa chips. LoRaWAN defines the Media Access Control (MAC) layer at the data link level and is overseen by the LoRa Alliance. It's crucial to distinguish between LoRa and LoRaWAN because companies like Link Labs utilize a proprietary MAC layer in conjunction with LoRa chips to create more advanced hybrid designs, such as Link Labs' Symphony Link.

LoRaWAN typically employs a star or star-to-star topology, which is generally considered superior to mesh networks due to advantages such as conserving battery power and extending communication range. In a star topology, messages are relayed to a central server through gateways, and each end node can transmit data to multiple gateways. These gateways then forward the data to the web server, where tasks like redundancy detection, security checks, and message scheduling are executed.

In summary, LoRa encompasses solely the link layer protocol, making it suitable for point-to-point (P2P) communication between nodes. In contrast, LoRaWAN includes the network layer, allowing data to be sent to any base station connected to a cloud platform. By connecting the appropriate antenna to its socket, the LoRaWAN module can operate at different frequencies, offering versatility in its applications.

What is the IoT? Everything you need to know about the Internet of Things right now

The essence of IoT is networking that student of Top Information Technology College should be followed. In other words, technologies will use in IoT with a set protocol that they will use for communications. In Communication, a protocol is basically a set of rules and guidelines for transferring data. Rules are defined for every step and process during communication between two or more computers. Networks must follow certain rules to successfully transmit data.

While working on a project, there are some requirements that must be completed like speed, range, utility, power, discoverability, etc. and a protocol can easily help them find a way to understand and solve the problem. Some of them includes the following:

1. The List

There are some most popular IoT protocols that the engineers of top engineering colleges in Jaipur should know. These are primarily wireless network protocols.

2. Bluetooth

Bluetooth is a wireless technology standard for exchanging data over some short distances ranges from fixed and mobile devices, and building personal area networks (PANs). It is invented by Dutch electrical engineer, that is, Jaap Haartsen who is working for telecom vendor Ericsson in 1994. It was originally developed as a wireless alternative to RS-232 data cables.

3. ZigBee

ZigBee is an IEEE 802.15.4-based specification for a suite of high-level communication protocols that are used by the students of Best Engineering Colleges Jaipur to create personal area networks. It includes small, low-power digital radios like medical device data collection, home automation, and other low-power low-bandwidth needs, designed for small scale projects which need wireless connection. Hence, ZigBee is a low data rate, low-power, and close proximity wireless ad hoc network.

4. Z-wave

Z-Wave is a wireless communications protocol used by the students of BTech information technology college in Jaipur primarily for home automation. It is a mesh network using low-energy radio waves to communicate from appliance to appliance which allows wireless control of residential appliances and other devices like lighting control, thermostats, security systems, windows, locks, swimming pools and garage door openers.

5. Thread

A very new IP-based IPv6 networking protocol aims at the home automation environment is Thread. It is based on 6LowPAN and also like it; it is not an IoT applications protocol like Bluetooth or ZigBee. However, it is primarily designed as a complement to Wi-Fi and recognizes that Wi-Fi is good for many consumer devices with limitations for use in a home automation setup.

6. Wi-Fi

Wi-Fi is a technology for wireless local area networking with devices according to the IEEE 802.11 standards. Wi-Fi is a trademark of the Wi-Fi Alliance which prohibits the use of the term Wi-Fi Certified to products that can successfully complete interoperability certification testing.

Devices that can use Wi-Fi technology mainly include personal computers, digital cameras, video-game consoles, smartphones and tablets, smart TVs, digital audio players and modern printers. Wi-Fi compatible devices can connect to the Internet through WLAN and a wireless access point. Such an access point has a range of about 20 meters indoors with a greater range outdoors. Hotspot coverage can be as small as a single room with walls that restricts radio waves, or as large as many square kilometers that is achieved by using multiple overlapping access points.

7. LoRaWAN

LoRaWAN is a media access control protocol mainly used for wide area networks. It is designed to enable students of private engineering colleges in Rajasthan to communicate through low-powered devices with Internet-connected applications over long-range wireless connections. LoRaWAN can be mapped to the second and third layer of the OSI model. It is implemented on top of LoRa or FSK modulation in industrial, scientific and medical (ISM) radio bands.

8. NFC

Near-field communication is a set of communication protocols that enable students of best engineering colleges in Rajasthan two electronic devices. One of them is usually a portable device like a smartphone, to establish communication by bringing them within 4cm (1.6 in) of each other.

These devices are used in contactless payment systems like to those used in credit cards and electronic ticket smartcards and enable mobile payment to replace/supplement these systems. Sometimes, this is referred to as NFC/CTLS (Contactless) or CTLS NFC. NFC is used for social networking, for sharing contacts, videos, photos, or files. NFC-enabled devices can act as electronic identity both documents and keycards. NFC offers a low-speed connection with simple setup that can be used by the students of top Engg colleges in Rajasthan to bootstrap more capable wireless connections.

9. Cellular

IoT application that requires operation over longer distances can take benefits of GSM/3G/4G cellular communication capabilities. While cellular is clearly capable of sending high quantities of data, especially for 4G with the expense and also power consumption will be too high for many applications. Also, it can ideal for sensor-based low-bandwidth-data projects that will send very low amounts of data over the Internet. A key product in this area is the SparqEE range of products including the original tiny CELLv1.0 low-cost development board and a series of shield connecting boards for use with the Raspberry Pi and Arduino platforms.

10. Sigfox

This unique approach in the world of wireless connectivity; where there is no signaling overhead, a compact and optimized protocol; and where objects are not attached to the network. Sigfox offers a software-based communications solution to the students of top engineering colleges in India where all the network and computing complexity is managed in the Cloud, rather than on the devices. All that together, it drastically reduces energy consumption and costs of connected devices.

SigFox wireless technology is based on LTN (Low Throughput Network). It is wide area network-based technology which supports low data rate communication over larger distances. It is mainly used for M2M and IoT applications which transmits only few bytes per day.

Choosing the Best IoT Data Connectivity for IoT Platform

IoT data connectivity is the most fundamental requirement of an IoT use case. However, not every IoT platformutilizes the same connectivity solutions. In order to maximize the benefit from an IoT business, one needs to have the most appropriate connectivity solution.

Selecting the Best Wireless Technology for IoT

IoT is a diverse technology. There are many IoT sensors that remain connected and transmit signals to ensure proper implementation of an IoT network. For someone trying to leverage IoT for best gains, it is important to have information about every type of IoT connectivity available.

Have a look at some IoT connectivity types and their best use scenarios:

Mobile Network Connectivity

3G, 4G and 5G are the most basic cellular network connectivity types available. When you have to cover large areas, mobile connectivity becomes a necessity. For example, connected cars can move around and still communicate if they are powered by mobile connectivity. In the future, it is expected that 5G-connectivity would power a vast network of self-driving cars. Mobile connectivity is also widely used for long-range IoT surveillance systems.

Low Powered Long Range Connectivity

When you want your IoT devices to be operational for a long time on a single battery charge, Low Powered Long Range Connectivity solutions like SigFox, LoRA, LTE-M and NB-IoT become the ideal choice. These connectivity types maintain a low data rate, which does not exert the sensors. Hence, a single battery charge lasts for a long time and the battery life is also extended. Important use cases for this type of connectivity are monitoring of environment, tracking of assets and monitoring of perishable items.

Mesh Protocols

When there is a need to supply connectivity to several sensors connected in a mesh topology, connectivity solutions like Zigbee are preferred. Although they have a short range of 100 meters or less, they are very effective in reducing the power consumption by sensors.

Wi-Fi Connectivity

When you need to connect a home network that has many IoT devices, Wi-Fi is the most suitable choice. Although it is an expensive connectivity type, it can provide greater bandwidth and low latency. Mostly, it is used for connecting home gadgets and appliances.

When it comes to IoT development, you need the most ideal connectivity solutions for maximum benefit. However, IoT is a vast field and requires greater resources. To fulfill this requirement, it is essential to have an internet of things connectivity provider that can offer versatile connectivity solutions.

Secure IoT Services excels at both connectivity and IoT billing solutions. It also offers superior tech support, so that your network remains operational at all times.

Point-to-Point (P2P) transmission refers to direct data communication between two devices, suitable for long-distance transmission or scenarios where monitoring points are widely dispersed.

Point-to-Multipoint (P2MP) transmission, which is slightly more complex, experiences greater signal loss during transmission compared to point-to-point (one-to-one) transmission. Therefore, it is suitable for situations where monitoring points are more concentrated, numerous, and the transmission distance is relatively short.

Functional Features of Data Transmission Radios

The data transmission radio supports a wide voltage input range (9-30V), making it suitable for various power supply environments. It features ultra-long-distance communication capabilities and a dual-antenna design, ensuring signal stability and reliability. The module has a built-in RS485 interface with an isolation circuit, providing electrostatic protection and standing wave protection, ensuring safe operation in harsh environments. It uses a custom aluminum alloy housing to enhance durability and heat dissipation performance.

The device also features a built-in hardware watchdog reset circuit that automatically restarts the device in case of anomalies, ensuring continuous and stable operation. Additionally, it has strong anti-interference capabilities, effectively resisting external strong interference signals, further enhancing the device's reliability and stability.

Multiple protection functions, such as reverse power protection, over-connection protection, and antenna surge protection, significantly increase the radio's reliability.

Operating temperature range: -40℃ to +85℃, suitable for various harsh working environments, truly an industrial-grade product.

Powerful software features include AES128 data encryption, LBT (Listen Before Talk) function, and the ability to set parameters such as node/router/node+router options in MESH mode easily and quickly via a PC interface.

Selectable hop count in MESH mode: In MESH mode, the device allows users to select the hop count for data transmission. This feature optimizes network topology according to specific needs, controls transmission delay, and ensures effective data delivery in complex multi-hop networks, thereby enhancing network flexibility and reliability.

MESH self-organizing network: Developed by NiceRF, the MESH algorithm features automatic routing, forming a network transmission system with no blind spots and no distance limitations.

Precautions for Using High-Power Wireless Data Transmission Radios

Select a suitable DC regulated power supply with strong high-frequency interference resistance, low ripple, and sufficient load capacity. It is also necessary for the power supply to have overcurrent protection, overvoltage protection, and lightning protection functions.

Do not use the radio in environments that exceed its specified characteristics, such as high temperatures, high humidity, low temperatures, strong electromagnetic fields, or dusty conditions. These environments can significantly wear down the radio, shorten the lifespan of internal components, and cause substantial signal attenuation in strong electromagnetic environments, hindering wireless signal transmission.

The ground wire of the data transmission radio should be well-connected to the ground wire of external devices (such as PCs, PLCs, etc.). Otherwise, it can easily damage the communication interface or cause signal transmission instability, leading to errors and other issues.

Antenna Selection Precautions for Data Transmission Radios

To ensure optimal communication distance for the module, follow these principles during antenna usage:

Antenna Positioning: Avoid placing the antenna close to the ground surface and keep it away from obstacles.

Magnetic Base Antennas: If using a magnetic base antenna, straighten the lead wire as much as possible, and attach the base to a metal object.

Yagi Antennas: For Yagi antennas, it is recommended to place the transmitting antenna vertically and the receiving antenna horizontally.

Note: Due to the high power output, ensure the antenna is connected before the radio starts transmitting to avoid damaging the internal power amplifier module.

Antenna Distance: The distance between the receiving and transmitting antennas should be greater than 1.5 meters.
