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overlap with those used by channels 120-124 on GSM cellular phones and thus these original frequencies have been withdrawn from use ...
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 ...

MOBILE SERVICE (generic frequency allotment) standard digital cordless phones - 40 to 50 MHz; MOBILE SERVICE baby monitors - 49 MHz; MOBILE SERVICE radio controlled airplanes - around 72 MHz; Mobile service cell phones - 824 to 849 MHz; Space research service (deep space) - 2290 MHz to 2300 MHz [6]
The C band also includes the 5.8 GHz ISM band between 5.725 and 5.875 GHz, which is used for medical and industrial heating applications and many unlicensed short-range microwave communication systems, such as cordless phones, baby monitors, and keyless entry systems for vehicles.
Using wired phones, which do not transmit. Using cordless phones that do not use the 2.4 GHz band. Using the 5 GHz band. DECT 6.0 (1.9 GHz), 5.8 GHz or 900 MHz phones, commonly available today, do not use the 2.4 GHz band and thus do not interfere. VoIP/Wi-Fi phones share the Wi-Fi base stations and participate in the Wi-Fi contention protocols.
