UMobile 802.16e

Wavesat and IBM have partnered to develop of a high performance, power-efficient 802.16e WiMAX chipset targeting consumer electronics devices supporting advanced mobile wireless broadband services. As part of the agreement, Wavesat's UMobile 802.16e chipset will be manufactured by IBM using advanced eDRAM process technology. By eliminating the need for any external memory, Wavesat's customers will benefit by saving valuable real estate, cost and power consumption for very small form-factor mobile applications such as wireless dongles and mobile handsets.

Wavesat's memory, Mobile chipset also integrates in a customized embedded processor built on IBM Power Architecture technology running at up to 400MHz, providing the right processing power required for WiMAX Wave 2 profile including MIMO, and enabling high throughput. IBM and Wavesat are also collaborating on innovative power saving techniques such as voltage islands, aimed at lowering chipset power consumption and maximizing power efficiency for different modes of operation.

"This is a landmark announcement for Wavesat and we are very pleased to team up with IBM for our mobile WiMAX chipset", said Vijay Dube, president and COO for Wavesat. "IBM will work hand in hand with us to design, manufacture, and jointly market our UMobile 802.16e chipset to provide our clients with the industry's best performance, lowest power consumption and most advanced design available."

"We are pleased to be working with Wavesat to provide 4G mobile WiMAX chipsets targeting consumer electronic devices," said Richard Busch, director of ASIC products, and power architecture licensing and cores for IBM's global engineering solutions unit.

Wavesat has been heavily involved with the development of IEEE 802.16 d/e standards and WiMAX Forum activities, including Plugfests and certification. Wavesat will release in Q4 the 802.16e UMobile family, codenamed Panther, which it says exceeds WiMAX Forum Wave 2 certification requirements.

The chipset offers very high performance and fully programmable PHY & MAC solution, including smart antenna features such as MIMO 2x2. According to Wavesat, it is the lowest cost solution and footprint in the industry with embedded DRAM in a single package (no external memory required), allowing very easy integration into small form-factor applications. The device also features very low power consumption at 150mW in receive mode by using ultralow power DSP technology and enhanced power saving modes. The device also includes a highly programmable architecture supporting multimode operation including ODFMA/OFDM/ and 802.11a/g.
