Telecom Lead America: Sequans
Communications has tied up with ArrayComm, a multi-antenna signal processing
provider, to add a new technology to its LTE chip platforms called Sequans AIR
(Active Interference Rejection).
Sequans AIR is designed to increase throughput up to 3.5 times
for users at the cell edge and can increase network capacity up to 2 times.
“Though network-based interference mitigation techniques are
specified in future releases of the LTE standard, these are not available today
plus these are limited in how much interference they can remove. We designed
Sequans AIR in response to this, and have developed a powerful interference
solution that can be implemented on today’s LTE networks for significant
benefits to end users and network operators,” said Bertrand Debray, Sequans
CTO.
Sequans AIR will work in any LTE network (TDD or FDD),
regardless of eNode B, carrier frequency, or channel bandwidth. It currently
works on LTE Release 8 and 9 networks and will work on future Release 10 and 11
networks.
Sequans AIR is designed into Sequans’ latest LTE platforms:
Andromeda for LTE handsets and tablets and Mont Blanc for hostless USB dongles,
CPE, M2M devices, and mobile hotspots.
“Sequans AIR has been tested and proven at the system and
link level. It has been tested in numerous interference scenarios, using the
various transmission modes of LTE, and even in the most challenging situations
where there are numerous interfering signals to be rejected by only two UE
antennas, the Sequans AIR receiver shows a significant gain, rejecting in some
cases twice as much interference as the default receiver,” Debray added.
