  2. GSM frequency bands - Wikipedia

    en.wikipedia.org/wiki/GSM_frequency_bands

    Further GSM-850 is also sometimes called GSM-800 because this frequency range was known as the "800 MHz band" (for simplification) when it was first allocated for AMPS in the United States in 1983. In North America GSM-1900 is also referred to as Personal Communications Service (PCS) like any other cellular system operating on the "1900 MHz band".

  3. Cellular frequencies in the United States - Wikipedia

    en.wikipedia.org/wiki/Cellular_frequencies_in...

    The 1850–1990 MHz PCS band is divided into six frequency blocks (A through F). Each block is between 10 MHz and 30 MHz in bandwidth. Each block is between 10 MHz and 30 MHz in bandwidth. License (A or B) is granted for Major Trading Areas (MTAs).

  4. Cellular frequencies - Wikipedia

    en.wikipedia.org/wiki/Cellular_frequencies

    GSM had already been running for some time on US PCS (1,900 MHz) frequencies. And, some NMT-450 analog networks have been replaced with digital networks using the same frequency. In Russia and some other countries, local carriers received licenses for 450 MHz frequency to provide CDMA mobile coverage area.

  5. Frequency allocation - Wikipedia

    en.wikipedia.org/wiki/Frequency_allocation

    Frequency allocation (or spectrum allocation) is the part of spectrum management dealing with the designation and regulation of the electromagnetic spectrum into frequency bands, normally done by governments in most countries. [1] Because radio propagation does not stop at national boundaries, governments have sought to harmonise the allocation ...

  8. GSM Radio Frequency optimization - Wikipedia

    en.wikipedia.org/wiki/GSM_Radio_Frequency...

    GSM radio frequency optimization (GSM RF optimisation) is the optimization of GSM radio frequencies. GSM networks consist of different cells and each cell transmit signals to and receive signals from the mobile station, for proper working of base station many parameters are defined before functioning the base station such as the coverage area of a cell depends on different factors including ...

  9. Absolute radio-frequency channel number - Wikipedia

    en.wikipedia.org/wiki/Absolute_radio-frequency...

    In GSM cellular networks, an absolute radio-frequency channel number (ARFCN) is a code that specifies a pair of physical radio carriers used for transmission and reception in a land mobile radio system, one for the uplink signal and one for the downlink signal. ARFCNs for GSM are defined in Specification 45.005 Section 2.
