There are two main types of Cellular phone com usage, that being CMDA and GSM.
GSM operates, typically in a range of 850mhz, 900mhz, 1800 and 1900mhz. In parts of Europe it also uses 2100mhz. Older GMS specs can go as low as 380mhz for uplink and downlink and the channel will vary.
CDMA operates at usually at 800mhz or 1900mhz. Some of the 4g WiMax signals can run as high as 2.7ghz. That however is used for data, not for voice mode.
Again, different variations of this will run at other speeds but those are the most common ones.
It is the radio frequency (RF).
The operating frequency of 8085 is 3 mhz to 5 mhz
Operating frequency of Airtel900MHz Its 1800 Mhz in Mah.. where as Idea and BSNL works on 900 Mhz....
850 or 1900 will work

The operating frequency for an in-building cellular repeater system is the frequency your cellular provider uses in your area. For example, in the United States Sprint is a 1900MHz PCS carrier, therefore, if you want to repeat Sprint signals in your building you would need an external "Donor" antenna to receive the available Sprint 1900MHz signal outside, a cable would take the signal from the antenna to a powered amplifier designed to amplify the 1900MHz band. Another coax cable would go from the amplifier to the internal antenna in the building which is what your cellular phone would communicate with.

Dear All, Hutch operating frequency is 900Mhz.
The operating frequency of 8085 is 3 mhz to 5 mhz
The operating frequency for TATA Indicom CDMA is 800 MHz The operating frequency for TATA Docoma is 1800 MHz on 2G networks.

A.m. can be applied to a carrier of any frequency.
300MHz
For satllite communication the frequency should not be less than the critical frequency because in satellite communicaton high frequency is needed which is reflected by satellite but not by the ionosphere.
Microwaves are radio waves.Technically, "microwave" is the term used to designate radio communication onfrequencies above 3 GHz. Cellular and mobile data service doesn't operate inthat frequency range. But microwave systems operating in bands between5.8 GHz and 80 GHz are used to link the individual cellular and mobile data sitesto each other, and to the mobile switching centers.
it is noting but
