Project Wireless - February 2009 - (Page 7) PrOjeCT SPonSor aDvertISement Multi-tech hSDPA MoDeMS AvAilAble At Digi-Key from digi-Key, the socketmodem® hsdpa wireless modem is a complete, ready-tointegrate communications device that offers standards-based tri-band umts/hsdpa performance. this quick-to-market communications device allows developers to add wireless communication to products with a minimum of development time and expense. the socketmodem hsdpa wireless modem is based on industrystandard open interfaces and utilizes multi-tech’s universal socket design. featuring gsm circuit-switched data up to 9600 bps and umts data to 64k bps, the transceiver also has an integrated mmcX antenna connector and sim socket. clIck here for aDDItIonal InformatIon TAbLe 1 worldwIde aTTach raTeS In mobIle handSeTS also substantial savings in terms of cost and footprint. smart integration also refers to the ability of these different systems to share resources, and to be aware of what the other on-chip elements are doing. this minimizes the need for external components, and the overall cost and size of the final implementation is reduced even further. this approach also makes it easier to design multiple radios into any device by having a single chip that is pretested and supplied with the appropriate firmware for easy integration. to see an example of dumb integration, you only need to look at the early attempts at integrating two 2.4-ghz wireless technologies (Wi-fi and Bluetooth) into a single chip. gluing the two technologies together is straightforward enough, but making them work well together, especially if the two radios need to be active at the same time, is a completely different challenge. instead, a module integrating separate Bluetooth and Wi-fi chips can offer performance levels far in excess of single-chip solutions, with a similar physical footprint. in addition, coexistence software is available to ensure trouble-free operation of both radios.
