Sequans has integrated the Hellosoft Voice over Internet Protocol (VoIP) HelloMediaEngine into its SQN1220 customer premise equipment (CPE) solution. The SQN1220 is the second member of the company’s SQN1200 series of chips, which Sequans says are the first Mobile WiMAX systems-on-a chip (SoCs) to integrate baseband and triple-band RF in a single 65-nm die (see the figure). According to Sequans, its collaboration with Hellosoft makes WiMAX VoIP CPE easier and quicker to develop at a lower cost, maximizing performance and minimizing time-to-market for Mobile WiMAX device manufacturers.

Sequans has integrated the Hellosoft VoIP HelloMediaEngine into its SQN1220 CPE solution. This collaboration aims to make WiMAX VoIP CPE easier and quicker to develop at a lower cost, maximizing performance and minimizing time-to-market for Mobile WiMAX device manufacturers.

HelloSoft says that its highly optimized, field-proven HelloMediaEngine is designed to deliver a top-notch VoIP experience. It supports a wide range of ITU-T narrow-band and wide-band speech codecs and incorporates a highly optimized echo canceller and noise canceller. Also, its well-defined interface provides easy integration with SIP signaling stacks, audio/SLIC interfaces, and RTP/RTCP stacks. 

Based on 65-nm technology, the SQN1220 delivers dramatically reduced power consumption, size, and cost over previous-generation technology, Sequans says. It includes an embedded network processor for higher processing power as needed for VoIP and CPE applications. Additionally, it features Sequans’ patent-pending mimiMAX£ technology, which comprises dual transmit channels for uplink multiple-input multiple-output (MIMO) and maximum likelihood MIMO performance for throughout of greater than 40 Mbits/s with extremely low power consumption. Uplink MIMO can nearly double cell coverage, and according to Sequans, the SQN1220’s power consumption is the lowest in the industry at less than 350 mW with fully loaded MIMO traffic.
