    v. t. e. A cellular network or mobile network is a telecommunications network where the link to and from end nodes is wireless and the network is distributed over land areas called cells, each served by at least one fixed-location transceiver (typically three cell sites or base transceiver stations ). These base stations provide the cell with ...

    Mobile phone signal. A mobile phone signal (also known as reception and service) is the signal strength (measured in dBm) received by a mobile phone from a cellular network (on the downlink ). Depending on various factors, such as proximity to a tower, any obstructions such as buildings or trees, etc. this signal strength will vary.

  9. Comparison of wireless data standards - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_wireless...

    Typical 2G standards include GSM and IS-95 with extensions via GPRS, EDGE and 1xRTT, providing Internet access to users of originally voice centric 2G networks. Both EDGE and 1xRTT are 3G standards, as defined by the ITU, but are usually marketed as 2.9G due to their comparatively low speeds and high delays when compared to true 3G technologies.
