DWBS Capacity and Coverage
The DWBS 9630 Series WT is designed to provide the highest quality of mobility
service that wireless technology permits. Your system is designed for full
functionality and excellent voice quality throughout the areas where service is
provided as defined by your company’s communications director.
service that wireless technology permits. Your system is designed for full
functionality and excellent voice quality throughout the areas where service is
provided as defined by your company’s communications director.
Since this system uses RF signals for the communications channel to your WT,
there are situations when you may notice a difference in service from your wired
voice terminal. These situations may exist because it is difficult, if not
economically unreasonable, to provide flawless coverage in all areas (for
example, behind large metal storage or file cabinets, in a vault, or in a cold
storage locker). In many of these cases, your company decided, at the time your
system was designed, that perfect service in areas such as these is not
warranted.

While the DWBS features the highest capacity possible within the Federal
Communications Commission (FCC) regulations and Personal Wireless
Telecommunications (PWT) standards, the number of radio channels available is
limited and dependent on the amount of radio equipment installed. To put this in
perspective by relating it to your private branch exchange (PBX), a central office
(CO) trunk (dial 9) is not provided for every user; in fact, a ratio of one CO trunk
per 10 users is common. Likewise, with DWBS, a radio channel is not available for
each user throughout your defined coverage area. Therefore, if a large number of
users attempts to use the system by either making or receiving calls at the same
time and in the same area, a radio channel may not be available; this results in a
“No Channel Available” condition. An example of this would be if a large number
of users were to attend a training course on the DWBS and, after the pocket
phones were distributed at the end of the class, more users attempted to call each
other than is allowed by the number of radio channels available in the area.

As you move about your premises, the system may not be able to find an idle
radio channel to allow you to continue an active call because the area you are
entering is very busy. This may result in a degraded connection, even when you
are in an area that usually provides good coverage. Most likely, the difficulty is
