Range
802.11a	Indoor (typical)	Outdoor (typical)
	500 ft (152 m) @ 6 Mbps	950 ft (290 m) @ 6 Mbps
	400 ft (122 m) @ 18 Mbps	800 ft (244 m) @ 18 Mbps
	90 ft (27 m) @ 54 Mbps	170 ft (52 m) @ 54 Mbps
	Note The above range numbers assume that the client adapter is
	being used at maximum transmit power with a Cisco Aironet
	1232AG Access Point with a 3.5-dBi dipole antenna.
	Different range characteristics are likely when using the
	client adapter with a different access point or a Cisco Aironet
	1200 Series Access Point with a different antenna.
802.11b/g	Indoor (typical)	Outdoor (typical)
	410 ft (125 m) @ 1 Mbps	700 ft (213 m) @ 1 Mbps
	300 ft (91 m) @ 6 Mbps	650 ft (198 m) @ 6 Mbps
	220 ft (67 m) @ 11 Mbps	490 ft (149 m) @ 11 Mbps
	180 ft (55 m) @ 18 Mbps	400 ft (122 m) @ 18 Mbps
	90 ft (27 m) @ 54 Mbps	110 ft (34 m) @ 54 Mbps
	Note The above range numbers assume that the client adapter is
	being used at maximum transmit power with a Cisco Aironet
	1232AG Access Point with a 2.2-dBi dipole antenna.
	Different range characteristics are likely when using the
	client adapter with a different access point or a Cisco Aironet
	1200 Series Access Point with a different antenna.
