Broadband

We have been deeply involved in broadband wireless access systems for over ten years. Projects range from totally custom designs to proprietary extensions of 802.11 and DOCSIS standards. With the advent of WiMAX standards, we have become leaders in base and subscriber station design using standards based technology blocks. As early members of the WiMAX forum, we have established key ecosystem partners and have produced designs from 1.9 to 5.9 GHz. Growth of bandwidth-intensive applications is accelerating deployment of 4G networks. Despite the improvements that these IP based networks will provide, bandwidth on the air interface is still the limiting factor. Our experience and well equipped facility position us particularly well to handle the RF subsystem challenges of access technologies such as LTE, HSPA+ and WiMAX.

We are experienced in:

• OFDMA/SCFDMA signalling
• Adaptive modulation and coding schemes.
• Advanced modulation techniques - BPSK, QPSK, 16-QAM, and 64-QAM
• Multiple-Input-Multiple-Output (MIMO) transceiver technology
• Achieving excellent dynamic range, phase noise, adjacent channel performance
• A variety of Radio to baseband interfaces

We can provide:

• Terminal, base station or subsystem design
• SW integration, RF Drivers, existing product customization
• Custom Antenna design
• Radio 16 - 5.8 GHz WiMAX reference design
