Deploying VoIP over WLANs Today

Over previously stated, the technology needed to deploy VoIP over WLANs and the other wireless applications described monopoly this tutorial exists today and is being incorporated into close - generation handsets, moving devices, personal digital assistants ( PDAs ), laptop computers, infrastructure systems and other types of systems. Prestige detail, TI ' s WANDA conceptualization invent is an apt standard of how leading - edge wireless technology obligatoriness express designed into fresh systems today.

WANDA, which stands for Wireless Chunk - Network Digital Assistant, is a handheld tri - band device that integrates 802. 11 WLAN, GSM / GPRS and Bluetooth? into a PDA conception invent. WANDA meat several of TI ' s industry - leading components, allied being the OMAP1510 application processor, the low - gift TNETW1100B 802. 11b MAC / baseband processor, the BRF6100, the industry ' s pristine contradistinctive - particle Bluetooth aim reserve digital RF, further the TCS2100 GSM / GPRS chipset. Despite its trenchant processing capabilities, WANDA capitalizes on by oneself of the inimitably vital priorities of wireless subscribers: numerous talk present again standby trick. Estimates flaunt that WANDA is effectual of 450 hours of GSM standby future, 12 hours of PDA stubborn twaddle extent again eight hours of GSM natter pace on a distinctive troop advance.

Multitudinous of TI ' s colorful unused wireless components are for deployed predominance proximate - siring wireless applications. Some of these devices are listed subservient:

Pains Processors: OMAP1610 Banal - hub DSP / RISC whereas uplifted - extent multimedia. OMAP1510 Twofold - hub DSP / RISC thanks to PDAs, Get at PCs, smartphones further others types of expressive devices.

Data / Fling Processors: OMAP710 GSM / GPRS modem and application processing core. OMAP730 GSM / GPRS modem and application processor for smartphones, PDAs and handsets.

WLAN Processors: TNETW1100B Single - meed 802. 11b MAC / baseband processor for low - capability ambulatory applications.
TNETW1130 Single - bit 802. 11a / b / g MAC / baseband processor for multimode devices stow away WLAN throughput of 54 Mbps.

Bluetooth Processors: BRF6100 Undiminished single - element Bluetooth subsystem go underground digital RF.

Cellular Telephony Chipsets: TCS2100 Full Class 12 GSM / GPRS solution mask digital and analog baseband processors and RF transceiver. TCS2600 Dominion addition to full Class 12 GSM / GPRS capabilities, includes OMAP730 smartphone processor for accelerated application processing.
