Appendix B Technical Specifications Table B-1 Technical Specifications for CB21AG and PI21AG Client Adapters (continued) Receiver delay spread (multipath) 802.11a/g 400 ns @ 6 Mbps 250 ns @ 9 and 12 Mbps 220 ns @ 18 Mbps 160 ns @ 24 Mbps 100 ns @ 36 Mbps 90 ns @ 48 Mbps 70 ns @ 54 Mbps 802.11b 350 ns @ 1 Mbps 300 ns @ 2 Mbps 200 ns @ 5.5 Mbps 130 ns @ 11 Mbps Range 802.11a Indoor (typical) 500 ft (152 m) @ 6 Mbps 400 ft (122 m) @ 18 Mbps 90 ft (27 m) @ 54 Mbps Outdoor (typical) 950 ft (290 m) @ 6 Mbps 800 ft (244 m) @ 18 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) 410 ft (125 m) @ 1 Mbps 300 ft (91 m) @ 6 Mbps 220 ft (67 m) @ 11 Mbps 180 ft (55 m) @ 18 Mbps 90 ft (27 m) @ 54 Mbps Outdoor (typical) 700 ft (213 m) @ 1 Mbps 650 ft (198 m) @ 6 Mbps 490 ft (149 m) @ 11 Mbps 400 ft (122 m) @ 18 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.
