Wireless Characteristics of Cisco Unified Wireless IP Phone 7925G-EX
Description
IEEE 802.11a, 802.11b, and 802.11g
FCC: (-A)
● 2.412–-2.462 GHz; 11 channels
● 5.15–-5.25 GHz Unlicensed National Information Infrastructure (UNII-1), 5.25–-5.35 GHz (UNII-2), and 5.725–-
5.825 GHz (UNII-3); 12 channels
● 5. 47–-5.725 GHz; 11 channels
ETSI: (-E)
● 2.412–-2.472 GHz; 13 channels
● 5.15–-5.725 GHz; 19 channels
Japan: (-P)
● 2.412–-2.472 GHz; 13 channels Orthogonal Frequency Division Multiplexing (OFDM)
● 2.412–-2.484 GHz; 14 channels Complementary Code Keying (CCK)
● 5.15–-5.725 GHz; 19 channels
Rest of World: (-W)
● Uses IEEE 802.11d to identify band ranges and channels
● IEEE 802.11a
● IEEE 802.11b/g
● Autosensing, IEEE 802.11b/g preferred over IEEE 802.11a
● Autosensing, IEEE 802.11a preferred over IEEE 802.11b/g
● Received signal strength indicator (RSSI) (default)
IEEE 802.11a:
6, 9, 12, 18, 24, 36, 48, and

● 36 Mbps: -80 dBm
● 48 Mbps: -77 dBm
● 54 Mbps: -75 dBm
IEEE 802.11a OFDM:
● 40 mW (16 dBm)
● 32 mW (15 dBm)
● 20 mW (13 dBm)
● 8 mW (9 dBm)
● 3.2 mW (5 dBm)
● 1 mW (0 dBm)
IEEE 802.11b:

● 6 Mbps: -91 dBm
● 2 Mbps: -95 dBm
● 9 Mbps: -90 dBm
● 5.5 Mbps: -90 dBm
● 12 Mbps: -87 dBm
● 11 Mbps: -87 dBm
● 18 Mbps: -86 dBm
● 24 Mbps: -82 dBm
● 36 Mbps: -80 dBm
● 48 Mbps: -77 dBm
● 54 Mbps: -76 dBm

● 20 mW (13 dBm)
● 32 mW (15 dBm)
● 8 mW (9 dBm)
● 20 mW (13 dBm)
● 3.2 mW (5 dBm)
● 8 mW (9 dBm)
● 1 mW (0 dBm)
