2.2.2 Cell Coverage
In a typical office environment where there are some obstacles, the coverage area of the LWS-BS cell is
approximately 15 ~ 30 meters. A better coverage distance could be achieved in more open areas. The
coverage area is however, truly dependent on the office environment characteristics (e.g. construction
material of walls, metallic objects, doors, windows, stair-wells, etc). Other radio equipment such as
DECT phones or WIFI equipment could also affect the coverage area. The coverage area will be unique
for each office environment.
2.2.3 General Guidelines
1. Try to locate the LWS-BS in such a way to maximise the direct line of sight between the wireless
terminals and the LWS-BS antenna.
2. Try to minimize obstructions near the antenna of LWS-BS.
3. Where possible, centralize the LWS-BS within the desired coverage area that you intend to cover.
4. In an office environment, consider the office furniture in order to minimize reflection, diffraction and
scattering of the DECT radio waves when you choose the position of the LWS-BS.
5. Try not to locate the LWS-BS on top of any steel furniture.
6. Electronic equipment such as a copy machine, a printer or a computer might have an influence on
the coverage area.
7. Try to locate the LWS-BS in an open area. Avoid areas such as high traffic areas, corners and
narrow walkways.
8. When moving around while busy on a wireless handset, you may experience degradation in
speech quality (e.g. breaking up of speech). If this happens, rather stand still during the call.
