Telstra was the first carrier in Australia to launch VoLTE. The service was initially available on 6 phones (Four being iPhones and two being Samsung Galaxy's). [10] Telstra have switched on the VoLTE on every one of their 4G networks across Australia but currently the 4G small cells setup in regional Australia do not have VoLTE compatibility.
These are typically referred to as multi-band phones. Dual-band phones can cover GSM networks in pairs such as 900 and 1800 MHz frequencies (Europe, Asia, Australia and Brazil) or 850 and 1900 (North America and Brazil).
In Russia and some other countries, local carriers received licenses for 450 MHz frequency to provide CDMA mobile coverage area. Many GSM phones support three bands (900/1,800/1,900 MHz or 850/1,800/1,900 MHz) or four bands (850/900/1,800/1,900 MHz), and are usually referred to as tri-band and quad-band phones, or world phones; with such a ...
For technical details on UMTS and a list of its designated operating frequencies, bands, and their common names, see UMTS frequency bands. Networks on the global UMTS-bands 1 and 8 are suitable for global roaming in ITU Regions 1, 2 (some countries) and 3. Networks on UMTS-bands 2 and 4 allow roaming in ITU Region 2 (Americas) only.
From Tables 5.5-1 "E-UTRA Operating Bands" and 5.6.1-1 "E-UTRA Channel Bandwidth" of the latest published version of the 3GPP TS 36.101, [1] the following table lists the specified frequency bands of LTE and the channel bandwidths each band supports.
Frequency bands for 5G New Radio (5G NR), which is the air interface or radio access technology of the 5G mobile networks, are separated into two different frequency ranges. First there is Frequency Range 1 (FR1), [ 1 ] which includes sub-7 GHz frequency bands, some of which are traditionally used by previous standards, but has been extended to ...
Apart from their main spectrum holdings across large regions in the country (listed below) the major US carriers (AT&T, Sprint, T-Mobile & Verizon) also hold various Cellular Market Area (CMA) and/or Economic Area (EA) licenses for the AWS 1700 band, as well as Major Trading Area (MTA) and/or Basic Trading Area (BTA) licenses for the PCS 1900 band.
