4 Planning a Wireless

Network

Split the wireless networks

into multiple radio cells in

order to obtain an interfe-

rence-free radio network and

to make optimum use of the

radio ranges. Each cell then

only has one active transmit-

ter with at least one Mobile

Panel. The access points are

the link that connects the

radio cells to the Ethernet.

2. Step: Position access points and determine the network

coverage

Insert the planned access points, select the antennae and align them. Determine

the planned access point's WLAN range:

3. Step: Simulate the WLAN devices and visualize the quality

of the signal

Use the simulation to check the range, signal intensity, interference of all the

WLAN devices and possible overlaps of the access points.

4. Step: Adapt the plan

Vary the arrangement of the access points until the required WLAN range is

covered to optimum effect.
