#Cellular Antennas CBRS

[rfantennaindia]

A 4G LTE internal PCB antenna is a type of antenna that is integrated directly onto a printed circuit board (PCB) and is designed to receive and transmit 4G LTE signals. These types of antennas are commonly used in mobile devices such as smartphones, tablets, and other wireless devices that require cellular connectivity.

The PCB antenna is typically made up of a thin copper layer that is etched onto the surface of the PCB. This copper layer is then designed to act as a conductor for the 4G LTE signals. The size and shape of the copper layer are carefully designed to match the frequency of the 4G LTE signal, which allows the antenna to efficiently transmit and receive signals.

One of the main advantages of a 4G LTE internal PCB antenna is that it is compact and does not require any external components or connectors. This makes it an ideal solution for space-constrained mobile devices. Additionally, because the antenna is integrated directly onto the PCB, it can help to reduce the overall cost of the device.

However, one potential drawback of an internal PCB antenna is that its performance can be affected by the surrounding environment. Factors such as the position of the antenna within the device, the materials used in the device's construction, and the proximity of other components can all affect the antenna's performance. Therefore, careful design and testing are necessary to ensure that the antenna meets the required performance specifications.

Enterprise-grade Wi-Fi systems have proven to be secure for thousands of demanding customers across virtually all industries. With the recent hype around 5G and service providers promoting 5G as an alternative to Wi-Fi in the enterprise, it pays to understand how 5G security stacks up against Wi-Fi security.

Cellular security has improved with each generation. The security of first-generation analog cellular systems, based on the AMPS (Advanced Mobile Phone System) standard, was essentially non-existent. These calls were unencrypted and could be intercepted with basic scanners. The security of currently deployed LTE networks is far better. LTE uses strengthened encryption and an authentication algorithm (“AKA”) that shares a key between the client and the receiving base station.

But while LTE security is solid, it isn’t perfect. According to researchers at Purdue and the University of Iowa, LTE is vulnerable to some types of cyberattacks, including data interception and device tracking. The Associated Press last year reported the US Department of Homeland Security (DHS) has acknowledged the existence in Washington, DC of cell site simulators, called “Stingrays,” that could track cellular devices, intercept calls, and potentially even plant malware. 5G security improves upon LTE security incrementally, with identical encryption, slightly hardened authentication, and better key management. But overall, 5G security is largely comparable to LTE security.

Just as cellular security has improved, Wi-Fi security has evolved with each generation. Early Wi-Fi networks, beginning in the late 90’s, used weak encryption and authentication, called “WEP”. The subsequent WPA and WPA2 standards feature improved encryption. Authentication with WPA2 can be either enterprise-grade 802.1X, or weaker PSK (pre-shared key), which hackers could potentially break by running through possible passwords until they can confirm the WPA2 handshake using a guessed password. This is called a Dictionary Attack. For this reason, most enterprises implement WPA2 with 802.1X, which is not prone to dictionary attacks. While some people claim Wi-Fi is insecure, pointing to poorly implemented networks that deactivate all password protection (e.g., a local coffee shop), this is not representative of enterprise practices. Still, the Wi-Fi industry developed WPA2 fifteen years ago, at a time when the wireless, computing, and security landscapes were substantially different.

Recently, the Wi-Fi Alliance (WFA) standards body responded with WPA3 – a significant update to Wi-Fi security. WPA3 implementations fall into one of three categories: (1) OWE (“Enhanced Open”), which encrypts traffic to prevent snooping attacks on open networks that do not have password protection, (2) WPA3-Personal, which uses a shared-secret and a cryptographically stronger key exchange that is resistant to dictionary attacks, and (3) WPA3-Enterprise, which significantly strengthens enterprise-grade 802.1X and optionally includes the same Suite B/CSNA crypto algorithms used for Top-Secret or higher classified government networks. Unlike 5G, which is not backward-compatible and requires completely new handsets and radio networks, enterprises can upgrade the software in many currently deployed Wi-Fi networks to include WPA3 (unless they are implementing Suite B/CNSA). The industry expects major handset OS vendors, such as Apple and Google, to roll out WPA3 and Enhanced Open by the end of 2019. WPA3 certification will be mandatory for all new Wi-Fi 6 equipment starting later this year.

Until this point, I’ve highlighted the evolution and current state of authentication, encryption, and key management for cellular and Wi-Fi standards. These are important security design elements. But it’s also important to consider an enterprise’s ability to tailor its networks to suit its needs by applying specific security and compliance tools and policies. The average security buyer at a large enterprise uses more than fifty different security and compliance tools, and no two organizations have exactly the same needs. Our customers have been successfully deploying their chosen security and policy tools to enterprise Wi-Fi networks for decades. The architecture of these networks is flexible and allows customers to break out, analyze, and apply policy to traffic. Wi-Fi 6 and WPA3 completely retain this flexibility.

5G is a different story. If an enterprise wants to replace Wi-Fi with 5G, there are a few different approaches. Each has implications for security customization.

The first approach is to extend macro 5G service into the enterprise using DAS (Distributed Antenna Systems) or small cells. With this approach, it is difficult to break out traffic and implement specific security solutions. In other words, you get what you get.

If your company is large enough, and your service provider is willing to sell and manage an individualized Network Slice, you could buy a slice specific to your company. Network slicing enables carriers to create customized virtual network overlays under one nationwide, physical network. With slicing, they can tune each of these virtual networks to serve business cases that require specific network characteristics. Your service provider may sell a low-latency network slice, or an IoT-oriented network slice. You could then have the service provider apply specific security solutions to that slice and possibly even manage it for you, as a part of their network. But all traffic passing over such a slice would be invisible to security appliances that are wired directly into an enterprise network.

Your enterprise could choose to deploy a private 5G network on your premises, using either spectrum licensed from a service provider, or possibly other spectrum that is unlicensed (e.g., CBRS spectrum). You can apply security to a private 5G network in a similar way you can apply it to an enterprise Wi-Fi network, but this requires investing in completely separate, parallel network infrastructure. Consequently, this approach will likely be limited to very specific enterprise use cases.

Security is not a monolithic consideration. It includes elements like authentication, encryption, and key management. For well-designed and deployed networks, these elements for Wi-Fi 6 are equal to, or better than, 5G. An equally important consideration is the ability of an enterprise to apply the specific security and policy tools to their network in a flexible way, tailored to its needs. Wi-Fi enterprise networks are highly flexible, as they always have been. But depending on the deployment approach for a 5G network, it may or may not be able to accommodate the level of security and compliance customization required by enterprise customers.

VR, parking spot finder, fitness equipment and more: defining the Smart Campus at THETA 2019

I had the pleasure of attending The Higher Education Technology Agenda (THETA) in May, and it was a magnificent event.  THETA is the number one biennial conference in Australasia promoting the intelligent use of information technology in higher education and research. Run under the direction of CAUDIT, CAUL, and ACODE, THETA 2019 was graciously hosted by the University of Wollongong.

The Ruckus team provided event-wide Wi-Fi for all attendees, connecting over 1,000 devices and delivering over 1TB of internet traffic handled – all with no issues and with fewer access points than originally planned due largely to Ruckus Beamflex+ technology.

I was excited to deliver my presentation, ”How to build a Smart Campus and make it uniquely valuable to your institution” which focused on three areas:

A deep dive on the need for change in higher education to address a struggling business model;

How a Smart Campus can help attract and retain students while lowering operating costs; and

How Ruckus uniquely addresses the challenges of deploying a smart campus while providing a platform for innovation to each institution.

What makes a smart campus ‘smart’ is not that it supports smartphones… rather, it is the deployment and use of IoT sensors to place the physical infrastructure of the campus onto IP networks to create situational awareness and programmed responses.  In other words, ‘sense something, do something.’  Is the room unoccupied?  Turn off the lights.  Is there motion outside the library entrance after midnight?  Turn on the overhead LED light and prioritize the nearby CCTV camera feed for security.

IoT sensors also allow institutions to create amazing new teaching and learning opportunities, such as hydroponic gardens, or update student experiences like knowing in real-time the wait time for lunch, fitness equipment, a laundry dryer, or a campus shuttle.

Too much of a good thing?

While it is tempting to immediately start your journey to a smart campus, be warned there are implementation challenges.  Current network trends indicate internet growth will continue for cellular, Wi-Fi, wired Ethernet, and IoT (machine-to-machine connections), with Wi-Fi bearing over 53% of all IP traffic by 2021.  In fact,  by that time IoT traffic is projected to double to 6% and M2M connections are expected to comprise over 50% of internet connections (source: Cisco VNI Forecast).

The impact on campus IT?

                Too much IP traffic – legacy networks are becoming overwhelmed

                Too many networks – student access IP networks, security CCTV, connected entry, HVAC, telecom, distributed antenna systems for cellular

                Too much radio interference –no standard to manage Zigbee/BLE/Wi-Fi on 2.4G

                Too little cellular signal – students cannot call mom from their residence

                Too many network stakeholders – who prioritizes, purchases, deploys and manages all these networks?  Do these disparate teams coordinate, or do their own thing?

                Too much cost and complexity – each IoT network is typically deployed independently, adding cost and complexity (gateway, dashboard, cabling, management) with each sensor solution

Work smarter, not harder, with converged access networks

Ruckus is busy inventing the future of converged access networks to allow IT to work smarter, not harder.  For example:

                Wireless convergence – Access points (APs) which manage Wi-Fi, Bluetooth, and Zigbee transmissions

                Wired convergence – Power and connectivity for APs, IoT (lights, cameras, locks, sensors) and computers

                Management convergence – Single pane-of-glass management for wired and wireless LAN

                IoT convergence – Single gateway, management platform, dashboard and rules engine for multiple IoT solutions

                Private LTE – CBRS, or OnGo, APs which deploy like Wi-Fi to provide strong cellular connections indoors or outdoors

Start your smart campus journey

By utilising a strong wireless/wired infrastructure, universities and colleges can combine IoT ingredients to design their recipes for a smart campus.

For example, last time at THETA I spoke alongside Kerry Holling, CIO and Chief Digital Officer of Western Sydney University (WSU), and discussed how we helped his team develop a ‘smart forest,’ where researchers from the Hawkesbury Institute for the Environment were injecting C02 from large cranes in the forest and measuring the impact with the assistance of Ruckus access points. This past November I was fortunate enough to visit and see for myself – impressive doesn’t do it justice.

This is just one example of how a great wireless and wired infrastructure can facilitate a completely new learning experience, and there are so many more out there. I look forward to returning for the next THETA in two years and sharing the latest advances in education technology.
