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.
The AM radio band falls in the comparatively low frequency range of 550 to 1600 KHz while FM radio operates in the 88 to 108 MHZ range and CB operates in the relatively narrow range of 26.95 to 27.405 MHZ. Cellular telephone operates in a frequency band of 825 to 890 MHZ.

Google Android is an operating system based on unix and java that currently operates cellular phones and is being experimented as a netbook operating system. Today you can find a lot of Android phones reviews on youtube, just search for it... The most important feature of Google Android is that it's an Open Source mobile operating system, meaning that any phone manufacturer can develop mobiles that use it. This has resulted in HTC, LG, Motorola, Samsung and many others all announcing the launch of Android based phones.
yes i had it before

Android is a mobile operating system designed to be run on cellular devices, and more recently tablet computers and television sets.
The basic concept of the very first cell phone was developed in 1947. When the first cell phone came out in 1968, it only had a frequency range of a few miles.
In the cellular phone system,cellular phones transmit and receive radio waves that travel to the nearest tower.Cellular phone transmit and receive high signals using high frequency microwaves.Hope this answers your question (: -anonymous xx
