In September 2014, Optus launched LTE Carrier Aggregation in Sydney, Melbourne, Brisbane and Adelaide. Optus markets LTE Carrier Aggregation as "4G Plus". Optus combines two 20 MHz channels of 2.3 GHz spectrum. [6] In Brisbane, Optus has up to 4CA band combinations using Band 1, 3, 7, 28 and the total bandwidth is 55 MHz.
5G Modes: FDD, TDD, SA (standalone), NSA (non-standalone) 5G mmWave specs: 1000 MHz bandwidth, 10 carriers, 2x2 MIMO; 5G sub-6 GHz specs: 300 MHz bandwidth, 256-QAM, 4x4 MIMO; 5G Peak Download Speed: 10 Gbit/s; 5G Global Multi-SIM support; Global 5G band support including the new n259 (41 GHz), n70 and n53 bands
Speeds on 2.5G networks are usually in the 30–50 kbit/s range. The first personal computer with a built-in mobile broadband modem was the ITC 286 CAT, a laptop by Intelligence Technology Corporation. Released in 1988, it featured a Hayes-compatible AMPS modem capable of transmitting data at 1.2 kbit/s. [3] [4]
In the mid-late 1990s, Telstra and Optus rolled-out separate cable Internet services, focusing on the east coast. The first broadband service over HFC was around 1995 using the Motorola proprietary protocols. In around 2000 DOCSIS was rolled out then in around 2008 the HFC was upgraded to support 30 Mbit/s.
Optus Mobile customers reported that their phones showed 'SOS' on the signal indicator, which is a sign the regular network is down, but mobile phones still have access to alternate networks in the event of an emergency call by using a so-called camping mechanism; however, Optus landlines were unable to make emergency triple-zero calls.
Voice over New Radio or Voice over 5G (acronym VoNR or Vo5G) is a high-speed wireless communication standard for voice services over 5G networks, utilizing mobile phones, data terminals, IoT devices, and wearables. [1] Like 4G networks, 5G do not natively support voice calls traditionally carried over circuit-switched technology. [2]
Later 3G releases, often denoted 3.5G and 3.75G, also provide mobile broadband access of several Mbit/s to smartphones and mobile modems in laptop computers. This ensures it can be applied to wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV technologies.
Hybrid fibre-coaxial is a legacy technology purchased by NBN Co from Telstra [96] and Optus. The Telstra HFC network is being maintained – it was found that the Optus HFC network was uneconomic to bring up to an acceptable standard, with these connections now to be provided by FTTC. [97] HFC connections use a DOCSIS cable modem as their NTD.
