The SQN1220 Mobile WiMAX system-on-a-chip (SoC) from Sequans Communications eliminates the need for an external CPU or DSP in voice/data customer premise equipment (CPE) and gateways. It also provides a high level of processing power to support combination voice and data applications, according to the company. Further, the SQN1220 integrates baseband and triple-band RF in a single 65-nm die.

The SoC uses the Sequans patent-pending mimoMAX technology, which comprises dual transmit channels to enable uplink multiple-input multiple-output (MIMO) and maximum likelihood MIMO performance for throughput greater than 40 Mbits/s. Uplink MIMO can nearly double cell coverage, and Sequans says that the SQN1220’s power consumption is the lowest in the industry at 350 mW with fully loaded MIMO traffic.

ODMs using the chip can take advantage of full reuse of the Sequans S3MAX software, which includes the entire 802.16e software stack and drivers for all major operating systems. Additionally, the SQN1220 provides an integrated network CPU that’s available to support Voice over Internet Protocol (VoIP) and networking applications. It supports the 2.3- to 2.4-GHz, 2.5- to 2.7-GHz, and 3.3- to 3.8-GHz bands as well.
