802.11a compared to 802.11b/g Coverage Area
Installation and Initialization
The 520wl is designed to support both 2.4 GHz (IEEE 802.11b), 2.4 GHz (IEEE 802.11g), and 5 GHz (IEEE 802.11a)
AP Cards. The HP ProCurve Wireless 802.11a Access Point Kit 160wl has an antenna adapter which snaps into place
on the existing wall mounting bracket. Because of the antenna adapter, only one 160wl card can be installed in the AP.
The second slot can be populated with an HP ProCurve Wireless Access Point card 150wl (802.11b), or 170wl
(802.11g).
Caution: Exposure to Radio Frequency Radiation.
To comply with the FCC RF exposure compliance requirements the following
antenna installation and device operating configurations must be satisfied:
a. For configurations using the integral antenna the separation distance
between the antenna(s) and any person's body (including hands, wrists,
feet, and ankles) must be at least 2.5 cm (1 inch).
b. For configurations using an approved external antenna the separation
distance between the antenna and any person's body (including hands,
wrists, feet, and ankles) must be at least 20 cm (8 inches).
The transmitter shall not be collocated with other transmitters or
antennas.
