In the United States, seven frequency bands have been allocated by the Federal Communications Commission for uses that include cordless phones. These are: 1.7 MHz (1.665–1.770 MHz, narrow-band FM) [8] Cordless phones manufactured after October 1, 1984, are not allowed to use this band and were required to use the newer (higher) 43-50 MHz ...
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. License (A or B) is granted for Major Trading Areas (MTAs). License (C to F) is granted for Basic Trading Areas (BTAs). License (G), where issued, is granted for Economic Areas (EAs).
The initial set of frequencies provided for a set 40 duplex channels using 25 kHz separation, with the phones transmitting in the 914-915 MHz band and the base stations in the 959-960 MHz band. These frequencies overlap with those used by channels 120-124 on GSM cellular phones and thus these original frequencies have been withdrawn from use ...
An Icom IC-R5 hand-held scanner A GMRS radio that also has scanning capabilities. A scanner (also referred to as a radio scanner) is a radio receiver that can automatically tune, or scan, two or more discrete frequencies, stopping when it finds a signal on one of them and then continuing to scan other frequencies when the initial transmission ceases.
20 kHz channel steps, some low-power frequencies 35.020–35.980 MHz 20 kHz channel steps, some low-power frequencies 37.440–37.880 MHz 20 kHz channel steps, often used for power and water company communications 42.960–44.600 MHz 20 kHz channel steps, some low-power or itinerant frequencies 47.440–49.580 MHz 20 kHz channel steps
Frequency: the DECT physical layer specifies RF carriers for the frequency ranges 1880 MHz to 1980 MHz and 2010 MHz to 2025 MHz, as well as 902 MHz to 928 MHz and 2400 MHz to 2483,5 MHz ISM band with frequency-hopping for the U.S. market. The most common spectrum allocation is 1880 MHz to 1900 MHz; outside Europe, 1900 MHz to 1920 MHz and 1910 ...
