The Key to Extending Your Wireless Transmission Range
Wireless LANs are great, but the current 802.11 standard can only take you so far. For example, it probably isn't a good idea to drag meters of wired connections across a dangerous minefield to connect minesweeping vehicles and equipment to the control center. Even if you used off-the-shelf access

Wired 8.03: Must Read
The air is thick with competing wireless standards for everything from cell phones to smart kitchens. For short-range device-to-device applications, the big name promises to be Bluetooth. For cable-free local area networking, think Wireless Ethernet - known at the IEEE as 802.11, but more familiar

Data on the go
Incremental improvements in chip technology help usher in the newest wave of flashy consumer electronics. The TNETW1250 chip from Texas Instruments supports 802.11 a, b, and g Wi-Fi standards. This lets designers of cell phones build in features like voice-overwireless LAN (VoWLAN), streaming media
