Section 3: Selecting a Location for the CPE
It is very important to position the Netkrom CPE and its antenna(s) to ensure the highest possible data transfer
speed in all kinds of weather and in all seasons. The Netkrom CPE operates on a radio frequency of 2.4 GHz
and must be line-of-sight (LOS) with its clients. Hills, buildings, trees and large vehicles must not block the signal
path. Trees are especially troublesome as they may allow the signal to pass easily in winter when leaves are off,
but may block the signal in the other seasons.
Choose a location on the roof, tower, mast or wall for your Netkrom CPE and antenna(s) so that it has a clear
shot to your base station or remote point. The closest client may not necessarily have the best path if it is
blocked by hills, buildings or trees.
Ensure that the signal path to each client has sufficient Fresnel zone clearance with respect to the ground or
other obstacles near the path. Check the Netkrom FAQ’s under “Radio Propagation” for more information on
Fresnel zone clearance.
Ensure that your mounting location is less than 100 meters from the computer, hub, switch or router location.
(Maximum length of CAT-5 cable is 100 meters) Determine the building entry point ahead of time to prevent
problems later.
