PxP Setup
Point to Point (PxP) mode is a Layer 2 transparent protocol optimized for
backhaul use. PxP mode is recommended whenever two network seg-
ments are to be bridged.
To operate the radio in PxP mode:
1. Set one radio to
Access Point
and the other to
Infrastructure Station
.
2. Enter the same
SSID
on both radios.
3. Set the
Channel
on the access point.
4. On both radios, enter the Mac address of the opposite radio in the
PxP Mac
Address
field (no colons).
5. Check off
PxP Mode Enabled
.
Note:
In PxP mode, the LEDs on the radios will operate the same as in Infrastructure
Station mode on both AP and CPE unit, with LEDs proportional to signal strength.
PxP Guidelines
There are a few guidelines you should follow when putting in a PxP link.
1.
Determine the locations for each side of the link.
2.
Determine the distance of the link and the heights of the installed equip-
ment.
3.
Using the details from step 2 check the Fresnel Zone and line of site.
4.
Verify that the line of site is free of obstruction.
Fresnel zone
The cross section radius of the Fresnel zone is the highest in the center of the RF LoS
which can be calculated as:
where
r
= radius in feet,
d
= distance in miles, and
f
= frequency in GHz.
