Samsung's 3GPP-Compliant PS-LTE Network

After having been discussed for years by others, Samsung finally announced back in April that they are powering the world’s first 3GPP-compliant nationwide public safety LTE (PS-LTE) network in Korea, in collaboration with leading mobile operators.

A press release from them said:

This PS-LTE network, operating in the 700MHz spectrum, offers fast and reliable connectivity to first responders in over 330 public safety organizations and agencies, including police, firefighters, emergency medical services and the military.

The deployment includes Samsung’s Mission-Critical Push-to-Talk (MCPTT) with multimedia broadcast capabilities, known as evolved Multimedia Broadcast Multicast Service (eMBMS). This enables simultaneous transmission to up to 2,500 user devices per cell, which is more than twice the volume of devices supported by previous generation technologies.

In this buildout, the PS-LTE network was also interconnected with the existing LTE-Maritime (LTE-M) and LTE-Railway (LTE-R) networks that were already operating in the 700MHz spectrum.

With nationwide coverage, the network serves as a unified platform that helps ensure interoperability among various public safety institutions. This delivers real-time accessibility and enhanced communications capabilities among public safety agencies and personnel in emergency situations.

They also released an Infographic and a Whitepaper.

In a recent Networks Techtalk, Timothy Paul discussed Samsung’s latest end-to-end MCPTX solutions that provide powerful data and video communications capabilities designed for first responders and public safety officials. The video of that is embedded below:

MatSing's High-Capacity RF Lens Antennas

We have looked at the Lens antennas in a few blog posts indirectly. The most recent being Facebook's SuperCell while others being Altaeros’ Autonomous Tethered Aerial Cell Tower and Verizon's U.S. Bank Stadium

In a recent press release, MatSing announced that it has been selected by the Dallas Cowboys and its network provider AT&T, along with ExteNet Systems, to provide mobile capacity antenna coverage for AT&T Stadium for the upcoming NFL season. Selected extract as follows:

These antenna upgrades will further enhance the exceptional experience provided by AT&T for fans in AT&T Stadium. This deployment follows a test run with reduced crowds during last season. This selection was made due to the capacity of MatSing technology to work with the AT&T systems at the stadium.

Following the installation of 20 MatSing lens antenna by ExteNet covering the Stadium’s entire seating bowl and field with 4G and 5G broadband mobile coverage, the fans and patrons will now experience never seen before performance with their smart devices in the stadium.

“With data demands of cell phones continuing to grow exponentially, driven by new apps and technology, our legacy DAS infrastructure could not keep up with those demands,” explained Cowboys CIO Matthew Messick. “AT&T introduced us to MatSing’s antenna technology, and immediately knew their technology would give us the necessary capabilities with room to grow.”

“Operating the largest indoor DAS network in the United States at AT&T Stadium provides us a unique opportunity to enable the best possible fan experience at one of the NFL’s most iconic venues,” added Rich Coyle, President & Interim CEO, ExteNet Systems. “We thank the Dallas Cowboys for trusting us with this opportunity, and MatSing for providing the clear winning technology for our mobile broadband needs.”

MatSing's spherical lens antennas are based on a unique patented technology that allows a single antenna to provide up to 48 high-capacity coverage sectors, replacing up to 48 traditional antennas with a single lens. Unlike other current solutions, like under-seat antennas, the MatSing lens antennas installed in the roofing structure typically have a clear line-of-sight path to potential users. This significantly reduces the number of antenna locations, as lens antennas can also reach farther than traditional antennas, providing better AT&T coverage and less interference at a lower cost and complexity for the team.

“A smoother Internet experience able to handle modern-day demands of streaming and social media sharing awaits Cowboys fans when they return to AT&T stadium,” added Michael Matytsine, MatSing co-founder and EVP of Operations. “Even when the stadium is at full capacity, lens antennas will provide a smoother data experience with fewer interruptions for fans who have embraced streaming and sharing as an intrinsic part of their stadium experience.”

AT&T, ExteNet and MatSing will continue to work with the Cowboys to maintain and test the lens equipment ahead of the season, ensuring its readiness for wider use by fans in AT&T Stadium.

MatSing lens antennas have also been present in the inauguration's of US presidents. The one from this year is in the Tweet above while the one from last election in 2016 is available here.

Panorama's ESN Antennas

It feels like last year when I was involved in testing some emergency networks but it was a long while back.

Believe it or not, your mobile network is only as good as the antennas. How often have I come across networks that try and add some cheaper antennas to cut down the costs but the loss of coverage, especially on the edges is a far bigger loss than saving some money on the antennas. 

The UK's Emergency Services Network (ESN) is moving along nicely, though far slower than most people expected it to. One of the important pieces of the puzzle is different types of antennas that are needed on the blue light vehicles. The image on the top nicely summarises these antennas and a brochure with details is available from Panorama here. In fact you can check out all different types of antennas here.

The following videos provide an idea on how these antennas look and work

Do check out other posts below related to ESN on our blogs.
