AP-51xx Access Point Product Reference Guide
2-6
To maximize the access point’s radio coverage area, Motorola recommends conducting a site survey
to define and document radio interference obstacles before installing the access point.
2.4.1 Site Surveys
A site survey analyzes the installation environment and provides users with recommendations for
equipment and placement. The optimum placement of 802.11a access points differs from 802.11b/g
access points, because the locations and number of access points required are different to support
the radio coverage area.
Motorola recommends conducting a new site survey and developing a new coverage area floor plan
when switching from 2 or 11Mbps access points (AP-3021 or AP-4131 models) to 54Mbps access
points (AP-5131 and AP-5181 models), as the device placement requirements are significantly
different.
2.4.2 Antenna Options
2.4.2.1 AP-5131 Antenna Options
Both Radio 1 and Radio 2 require one antenna and can optimally use two antennae per radio (4
antennae total for dual-radio models). Two antennae per radio provides diversity that can improve
performance and signal reception. Motorola supports two antenna suites for the AP-5131. One
antenna suite supporting the 2.4 GHz band and another antenna suite supporting the 5.2 GHz band.
Select an antenna model best suited to the intended operational environment of your AP-5131.
Antenna connectors for Radio 1 are located in a different location from the Radio 2 antenna
connectors. On single radio versions, the R-SMA connectors can support both bands and should be
connected to a R-SMA dual-band antenna or an appropriate single band antenna. If necessary a
R-SMA to R-BNC adapter (Part No. 25-72178-01) can be purchased separately.
NOTE
On a single-radio AP-5131, Radio 1 can be configured to be either a 2.4
GHz or 5.2 GHz radio. On a dual-radio model, Radio 1 refers to the AP-
5131’s 2.4 GHz radio and Radio 2 refers to the AP-5131 5.2 GHz radio.
However, there could be some cases where a dual-radio AP-5131 is
performing a Rogue AP detector function. In this scenario, the AP-5131 is
receiving in either 2.4 GHz or 5.2 GHz over the Radio 1 or Radio 2
antennae depending on which radio is selected for the scan.
