VoLTE calling. Voice over Long-Term Evolution (acronym VoLTE) is an LTE high-speed wireless communication standard for voice calls and SMS using mobile phones and data terminals. [1] [2] VoLTE has up to three times more voice [3] and data capacity than older 3G UMTS and up to six times more than 2G GSM.
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.
In November 2008, the International Telecommunication Union-Radio communications sector (ITU-R) specified a set of requirements for 4G standards, named the International Mobile Telecommunications Advanced (IMT-Advanced) specification, setting peak speed requirements for 4G service at 100 megabits per second (Mbit/s)(=12.5 megabytes per second) for high mobility communication (such as from ...
5G Spectrum: mmWave, sub-6 GHz, 5G/4G spectrum sharing; 5G Modes: FDD, TDD, SA (standalone), NSA (non-standalone) 5G mmWave specs: 800 MHz bandwidth, 8 carriers, 2x2 MIMO; 5G sub-6 GHz specs: 200 MHz bandwidth, 4x4 MIMO; 5G Peak Download Speed: 7500 Mbit/s; 5G Peak Upload Speed: 3000 Mbit/s; 5G RF: 100 MHz envelope tracking, Adaptive antenna tuning
The requirements were set forth by the ITU-R organisation in the IMT Advanced specification; but, because of market pressure and the significant advances that WiMAX, Evolved High Speed Packet Access, and LTE bring to the original 3G technologies, ITU-R later decided that LTE and the aforementioned technologies can be called 4G technologies.

4G networks provide even higher bitrates and many architectural improvements, which are not necessarily visible to the consumer. The current 4G systems that are deployed widely are WIMAX and LTE. The two are pure packet based networks without traditional voice circuit capabilities. These networks provide voice services via VoIP or VoLTE.
