Silicon Laboratories announced that it has partnered with Beceem Communications, WiMAX solutions vendor, to deliver a VoIP broadband gateway reference design for 4G-WiMAX service providers. The WiMAX VoIP gateway reference design is based on Beceem’s recently introduced BCS5350 single-chip WiMAX customer premises equipment solution. It also incorporates Silicon Labs’ Si32176 ProSLIC devices to provide the interface that enables the use of traditional home telephones for VoIP services over WiMAX.
