Telecommunications in Dominica comprises telephone, radio, television and internet services. The primary regulatory authority is the National Telecommunication Regulatory Commission which regulates all related industries to comply with The Telecommunications Act 8 of 2000. Telephony Calls from Dominica to the US, Canada, and other NANP Caribbean nations, are dialed as 1 + NANP area code + 7-digit number. Calls from Dominica to non-NANP countries are dialed as 011 + country code + phone number with local area code. ;Telephone system: *Domestic: fully automatic network *International: microwave radio relay and SHF radiotelephone links to Martinique and Guadeloupe; VHF and UHF radiotelephone links to Saint Lucia ;Number formatting: *Telephone code: 767 * Number Format: nxx-xxxx *Country Code: +1767 *International Call Prefix: 011 (outside NANP) ; Mobile cellular service providers: *Digicel *LIME Radio ;Radio broadcast stations: AM 0, FM 15, shortwave 0 (2007) ;Radios: ...

Microwave
Microwave is a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter corresponding to frequencies between 300 MHz and 300 GHz respectively. Different sources define different frequency ranges as microwaves; the above broad definition includes both UHF and EHF (millimeter wave) bands. A more common definition in radio-frequency engineering is the range between 1 and 100 GHz (wavelengths between 0.3 m and 3 mm). In all cases, microwaves include the entire SHF band (3 to 30 GHz, or 10 to 1 cm) at minimum. Frequencies in the microwave range are often referred to by their IEEE radar band designations: S, C, X, Ku, K, or Ka band, or by similar NATO or EU designations. The prefix ' in ''microwave'' is not meant to suggest a wavelength in the micrometer range. Rather, it indicates that microwaves are "small" (having shorter wavelengths), compared to the radio waves used prior to microwave te ...
