Sequans AIR receiver delivers 7dB in low mobility case during Softbank trials

Telecom Lead Asia: 4G chip provider Sequans Communications said its Sequans AIR receiver delivered 7dB in the low mobility case and 9dB in the high mobility case during a trial conducted with Japanese mobile operator Softbank.

Sequans’ AIR (advanced interference rejection) technology was tested to determine its value in mitigating interference in LTE networks.

The trial took place in a laboratory environment using commercial eNodeBs (base stations) commonly deployed in Softbank’s network.

For the trail, a receiver equipped with Sequans AIR was tested against a default receiver in both high mobility (vehicular) and low mobility (pedestrian) scenarios.

“In the low mobility case, we showed that a Sequans AIR receiver can handle about five times as much interference as a non-Sequans AIR receiver, and for the high mobility case, the Sequans AIR receiver can handle about eight times as much interference,” said Georges Karam, CEO of Sequans.

This translates into 10 Mbps higher throughput in the low mobility case and 14 Mbps higher throughput in the high mobility case. In very high interference areas, such as might be encountered near cell edges, users can expect to get three times better throughput.

“We have shown that operators who deploy Sequans AIR-equipped devices in their LTE networks are likely to have higher quality, higher performance LTE networks, and that their customers will enjoy a superior LTE experience. This is especially important for operators like Softbank that are deploying very dense LTE networks where interference can significantly reduce network capacity,” Karam added.

Sequans AIR-equipped end user devices are expected to be available in LTE networks in the first part of 2013.

4G NEWS: Recently Sequans Communications announced that Modacom, a Korean maker of wireless broadband data communications devices, has adopted its LTE chips to design LTE user devices.
