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.
Hand Drawn Maps of Internet from 1973. [7] The Center for Applied Internet Data Analysis (CAIDA) collects, monitors, analyzes, and maps several forms of Internet traffic data concerning network topology. Their "Internet Topology Maps also referred to as AS-level Internet Graphs [are being generated] in order to visualize the shifting topology ...
The broadband maps were then used by the CPUC to determine both "unserved areas" (defined as an area that is not served by any form of facilities-based broadband, or where Internet connectivity is available only through dial-up service or satellite) and "underserved" areas (defined as an area in which broadband is available but no facilities ...
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 ...
There are two types of subsetting, which can be combined: Trimming extracts a sub-area of a coverage indicated by a bounding box; the result has the same dimension (i.e., number of axes) as the original coverage. Slicing performs a cut at the position indicated, thereby reducing the dimension of the result coverage.

It makes use of native sensors on the phones, such as barometers, hygrometers, thermometers, magnetometers and lux-meters, to collect information sent in real-time to create live weather maps. [11] After one week over 2 million readings had been collected. [12] After iPhone 6 included a barometer, a version of the app for iPhone was released.
This timeline of Apple products is a list of all computers, phones, tablets, wearables, and other products made by Apple Inc. This list is ordered by the release date of the products. Macintosh Performa models were often physically identical to other models, in which case they are omitted in favor of the identical twin.
