Placing Rf Measurement Points - Nortel 2350 Reference Manual

150 Planning the Nortel WLAN 2300 System
If the coverage area provided by an access point on the floor above or below is one meter or less, WLAN Management
Software displays a message. This coverage area is not displayed on the current floor plan.
Resolving coverage gaps
You might see small "holes" when looking at the coverage areas at the baseline association rate. These small holes are
most likely areas where users still have wireless access but not at the baseline association rate. In most situations,
increasing transmit power levels to close the holes will generate more co-channel interference. Nortel recommends that
you allow these small holes during the planning process.
If you need to resolve the gaps in coverage, try the following:
1
Select the coverage area.
2
Right-click and select Show RF Coverage.
3
In the Show RF coverage using listbox, select how you want to display the coverage:
• Baseline Association Rate—Coverage is shown based on the AP radio baseline association
rate. The baseline association rate is the typical data rate the radio is expected to support for
client associations. (The baseline association rate is specified during planning, on a coverage
area basis.)
• Data Rate—Coverage is shown in colored bands that represent each of the data transmit rates
supported by the radio. These rates are standard for each radio type.
• RSSI—Coverage is shown based on the received signal strength indication (RSSI) of the
radio's signal heard by other radios.
If you need to make adjustments, do the following:
1
Move the APs, or increase the transmit power levels to provide better coverage.
2
Create more APs, and place them on the floor.
3
Modify the coverage area so that the capacity requirements are higher.
Note. If you manually add APs to a coverage area, they might be moved or removed when
you next perform Compute and Place.
Note. If you have already installed an AP in the network and you want to add it to the
coverage area, see
(page 447).

Placing RF Measurement Points

An RF measurement point on the floor plan simulates the measurement of signal strength from all APs at a specific
position on the floor. Placing RF measurement points is optional. RF measurement points are helpful for verifying the
wireless network. You can place as many RF measurement points as you want. You can place them anywhere and move
them later. Information from RF measurement points is included in a floor's work order.
