Cisco Aironet 1400 Series Bridge Software Configuration Guide, 12.2(15)JA

Channels and Antenna Settings

---

This appendix lists the IEEE 802.11a (5-GHz) channels and maximum power levels for the bridge supported by the Americas regulatory domain.

These topics are covered in this appendix:

•Channels

•Maximum Power Levels

Channels

IEEE 802.11a (5-GHz Band)

The channel identifiers, channel center frequencies, and regulatory domain of each 20-MHz-wide channel are shown in Table A-1.

Maximum Power Levels

5.8-GHz Band

An improper combination of power level and antenna configurations can result in equivalent isotropic radiated power (EIRP) above the amount allowed per regulatory domain. Table A-2 indicates the maximum power levels and antenna gains allowed.

Table A-2 Maximum Power Levels and Antenna Gains

Regulatory Domains	Maximum Power Settings
	Orientation	9-dBi Omnidirectional Antenna	9.5-dBi Sector Antenna	22.5-dBi Integrated Antenna	28-dBi Dish Antenna
Americas (-A)	P2P1	24 dBm	24 dBm	24 dBm	22 dBm
	P2MP2	24 dBm	24 dBm	123 dBm4	-

1 Point to point. 2 Point to multipoint. 3 A maximum of 13 dBm is allowed, but that setting is not supported by the bridge. 4 On point-to-multipoint links, the remote bridges communicating with the central bridge are allowed to use a maximum power setting of 24 dBm. The central bridge is limited to a maximum power setting of 12 dBm.
