Note:
The BS370 base station is not for new delivery, product is in
passive sustaining.
For more information about transmission pattern see chapter 6 Appendix
B: Radio base station signaling pattern on page 44.

Total area coverage
The base station coverage depends on the following factors:
•
The indoor cell size in offices may be in a range of 10 - 40m radius,
see figure 6 Example of maximum coverage of one base station on
page 15.
•
The cell size in exhibition- or production halls is up to 200m radius
(when free line of sight).
•
The outdoor cell size in free space may be up to 300m radius.
•
The base stations may partially cover floors immediately above and
below as well. The useful range through floors and ceiling varies
between 0 and 8m (2 floors) radius See figure 12 Measurement of
a typical cell size. on page 23
In this section different configurations are shown. In normal environ-
ments, all these configurations are mixed, due to the building’s construc-
tion, the users movement and usual location.
Note:
This section is based on standard antennas.
3.4.1
Minimum roaming and hand over traffic configuration
To keep the roaming and hand over traffic to a minimum, to avoid
roaming and hand over between floors and get best possible radio
performance it is preferred that the base stations are placed vertically
above each other, see figure 4 Example of a high call configuration.
ELU31 has 32 B-channel configuration. on page 14. This configuration
will also create a safer configuration in case a base station is out of
order.
