Sequans, JRC Develop LTE-Based Equipment for Public Safety at 200 MHz
Wednesday, July 25, 2018 | Comments

Sequans Communications and Japan Radio Company (JRC) developed a high-powered prototype customer premise equipment (CPE) based on Sequans Long Term Evolution (LTE) Cat 6 chip technology that is being prepared for public safety. The CPE was developed to operate on the 200 MHz frequency band — the band designated for public safety services in Japan — and includes a high-powered radio front end to ensure high-quality communications performance.

The new CPE and its capabilities were demonstrated to the Japanese government in February.

“We are proud to collaborate with JRC and pleased with the performance of this LTE CPE that has been developed to help public officials in Japan prepare communications services for public safety,” said Hugues Waldburger, vice president of Sequans’ broadband business unit. “We adapted our technology to operate on the 170 – 202.5 MHz LTE band and to perform at higher than normal output power of 37 dBm to meet the requirements of this special communications project. Our collaboration with JRC has yielded excellent results with a full demonstration of all planned capabilities.”

“Our work with Sequans over the last year to develop this CPE has now come to fruition, and we have achieved what we set out to do,” said JRC officials. “We had to meet very stringent RF specifications and we had to prove interoperability with infrastructure equipment, and at the end we have a very powerful and high performance CPE that meets all requirements.”

The prototype CPE complies with RF requirements for various profiles, including LTE, GSM-like, 1Rx or 2Rx. During testing, the product outperformed using the very low LTE frequency band that enables better indoor penetration while maintaining a reliable LTE communications link. The high transmission power, higher than the standard Third Generation Partnership Project (3GPP) power classes, enables cost-optimized network planning with larger cells.

The CPE complies with 3GPP Release 10 specifications and supports other Release 10 enhancements such as new multiple input multiple output (MIMO) schemes, enhanced inter-cell interference coordination (eICIC) schemes for heterogeneous networks (HetNets) and improvements to evolved multimedia broadcast multicast service (eMBMS).
