Type I systems do not use unique System IDs, thus the possibility exists for overlapping coverage in busy areas. The term SmartNet refers to a set of features that make Motorola Type I and II trunked systems APCO-16 compliant. These include better security, emergency signaling, dynamic regrouping, remote radio monitoring, and other features.
A coverage map may be produced to indicate the area in which a certain signal strength is delivered. [1] Even if it is 100% accurate (which it never is), a major factor on whether a signal is receivable depends very much on whether the receiving apparatus is sensitive enough to use a signal of that level.
Coverage depends on several factors, such as orography (i.e. mountains) and buildings, technology, radio frequency and perhaps most importantly for two-way telecommunications the sensitivity and transmit efficiency of the consumer equipment. Some frequencies provide better regional coverage, while other frequencies penetrate better through ...
Map of the 46 media markets in Canada. Markets are Designated Market Areas (DMAs), as listed at TV Radio World . Edmundston / Woodstock, NB is part of the Presque Isle, ME DMA .
In US broadcasting, service contour (or protected contour) refers to the area in which the Federal Communications Commission (FCC) predicts coverage.. The FCC calculates FM and TV contours based on effective radiated power (ERP) in a given direction, the radial height above average terrain (HAAT) in a given direction, the FCC's propagation curves, and the station's class.
Opensignal NetworkRank is an in-app service comparing the performance of different cellular carriers in particular regions. The service is a part of their carrier maps, which are colour-coded to show areas of strong and weak cell phone signal. The information used is provided by users of the Opensignal application. [5]
The following is a list of countries/territories by 4G LTE coverage as measured by OpenSignal.com in January, February and March 2019. [2] [3] Rank Country/Territory
Unlike the OGC Web Map Service (WMS), which portrays spatial data as static, server-rendered images (maps), the Web Coverage Service delivers underlying data values along with their detailed descriptions. This enables a rich syntax for queries against the data and returns information with its original semantics, rather than just pictures ...
