FCC registration Manual of PPC-10G 10Gbps radio links in the USA

The ELVA-1 team has created a set of recommendations for FCC registration to ensure that users in the United States are able to take full advantage of PPC-10G 10Gbps radio links.

The 70/80/90 GHz bands provide tremendous potential for the deployment of small, highly-directional antennas that can be used in multiple point-to-point radio links operating near each other. These miniature antennas are typically just 1 to 2 feet in diameter, yet they offer impressive levels of high directivity and gain while overcoming path loss can be estimated with ELVA’s link budget calculator.

The FCC’s move to facilitate the development and use of millimeter wave spectrum in 2003 opened up new possibilities for market. As a result, highly directional antennas can now be deployed in greater density than before, allowing users access to 10 Gbps or more of data at 70/80/90 GHz bands as an alternative or complementary means compared with fiber optic solutions. This has enabled urban areas and industrial hubs globally take advantage of this wireless transport network technology, including for 4G/5G base station deployments.

The FCC Commission adopted flexible rules for registering radio links for the 70/80/90 GHz bands, allowing for the registration of links with third-party database management operators after the Commission issues a geographic nationwide license.

Latest test of E-band 70-80 GHz 10 Gigabit V2X/V2N Light Rail Connectivity

For the first time in the industry, next-generation 10 Gbps wireless communications are being tested for a light rail.

This testing of V2N (Vehicle to Network) connectivity is aimed at the development of digital ecosystems in public transport. The project is being implemented in cooperation with the light rail operator Transport Concession Company.

ELVA-1 has announced the testing of PPC-10G-Rail 10-gigabit wireless communication system operating in the 70-80 GHz (71-76 / 81-86 GHz) band is being carried out on the light rail routes. The purpose of the tests is to develop ultra-broadband communication technologies between a network and moving vehicles (V2N), analyze the characteristics of a wireless connection and its availability at various distances between the rail transport and base stations, and also to collect traffic statistics for various weather conditions.

The existing technologies for connecting rail transport to the Internet (train-to-ground) are widely based on the use of GSM modems. In some of the projects, a network of roadside Wi-Fi access points is used. Both technologies are characterized by low connection speed (up to 300 Mbps) and handshaking delays when switching from one base station to another.
