5. Deploying VoIP over WLANs Today As previously stated, the technology needed to deploy VoIP over WLANs and the other wireless applications described in this tutorial exists today and is being incorporated into next-generation handsets, mobile devices, personal digital assistants (PDAs), laptop computers, infrastructure systems and other types of systems. In fact, TI's WANDA concept design is an apt example of how leading-edge wireless technology can be designed into advanced systems today. WANDA, which stands for Wireless Any-Network Digital Assistant, is a handheld tri-band device that integrates 802.11 WLAN, GSM/GPRS and Bluetooth™ into a PDA concept design. WANDA features several of TI's industry-leading components, such as the OMAP1510 application processor, the low-power TNETW1100B 802.11b MAC/baseband processor, the BRF6100, the industry's first single-chip Bluetooth solution with digital RF, and the TCS2100 GSM/GPRS chipset. Despite its impressive processing capabilities, WANDA capitalizes on one of the most important priorities of wireless subscribers: extended talk time and standby time. Estimates indicate that WANDA is capable of 450 hours of GSM standby time, 12 hours of PDA constant usage time and eight hours of GSM talk time on a single battery charge.
Many of TI's other advanced wireless components are being deployed in next-generation wireless applications. Some of these devices are listed below:
