Wireless Data Transmission
	n For in-building wireless coverage, wireless LAN technologies are available: Proxim, WaveLan, …. – Smaller coverage area, more controlled environment allow higher frequency/lower power transmissions, resulting in higher bandwidth n Other controlled environments: Bluetooth, Hiperlan, … – communication over short distance (“personal area networks”), again allow power/cost/bandwidth tradeoffs n These technologies typically do not provide wide- area coverage, but “islands of high connectivity”
