N721 GSM-GPRS-EDGE HSPDA reference design


u-blox licenses its market-proven GSM/GPRS/EDGE/HSDPA 3.5G modem reference design to OEM customers. The N721 design combines baseband processor, RF transceiver, antenna multiplexer and power amplifier components to support quad-band GSM/GPRS/EDGE/HSDPA functionality including voice, high-speed data and SMS capabilities.

The solution dramatically shortens time-to-market, and includes all hardware information, software binaries including stack, production test bench design and test software, certification, training and documentation. The result is a wireless, ultra-compact, low power communications solution which is easily integrated into consumer, industrial and automotive OEM designs, ready for high-volume mass-production.

Typical N721 applications include high-speed wireless data cards, smart-phones, mobile internet devices and high transmission bandwidth wireless applications such as streaming video.
