ABOUT COVERAGE MAPS
|
|
|
The maps provided here are based on composites of actual operating tests performed over a 38-month period. However, as with any wireless communications service, graphical coverage maps are an approximation of expected coverage provided by the service. | |
|
THE GRAPHICAL REPRESENTATIONS PROVIDED SHOULD NOT BE CONSTRUED
AS AN ABSOLUTE GUARANTEE OF ACTUAL SERVICE COVERAGE AT ANY GIVEN TIME.
| |
|
Dispatch Service coverage may be affected by a number of
factors:
|
|
|
The type of satellite terminal and antenna being used will affect coverage. For example, in certain geographical locations in the "fringe" of the service regions, super high-gain satellite terminals may provide adequate signal strength beyond the illustrated edge of the coverage region. |
|
|
Topographical features, both natural and "urban canyons", may inhibit the necessary line-of-site between the antenna of the satellite terminal and the AMSC - 1 satellite. |
|
|
For land mobile products, the starting location and direction of the vehicle will effect the satellite beam that the mobile terminal acquires, which may either restrict or extend the illustrated limits of coverage for a given service region. |
|
|
In service region areas where satellite beams overlap, the satellite terminal will attempt to lock onto the spot beam with the strongest signal strength. This is commonly referred to as "beam crossover". In the event that the terminal locks onto a beam outside of the talkgroup's defined service area, the user will be blocked from dispatch talkgroup communications. |
| - For these instances, the user can take advantage of the "Manual Beam Select" feature to temporarily move the satellite terminal to the proper beam. | |
| - Customers who consistently encounter such beam crossover problems should consider changing their service region to include the beam that most often causes the problem. | |
| POOR QUALITY EQUIPMENT INSTALLATIONS OR DAMAGED/DEFECTIVE HARDWARE COMPONENTS MAY ALSO ADVERSELY AFFECT A UNIT'S ABILITY TO ACHIEVE OPTIMAL COVERAGE PERFORMANCE. THIS IS ESPECIALLY TRUE IN THE CASE OF CRIMPED, TORN, OR OTHERWISE DAMAGED ANTENNA CABLES, WHICH WILL DEGRADE THE SIGNAL STRENGTH THAT THE TRANSCEIVER PROCESSES. | |
