Cell phones, SMS, Bluetooth, Wi-Fi, Miracast


  1. Australia's mobile phone history (plus photos) with Senior Constable Frederick William ("Pop") Downie of the Victorian Police credited with developing the world's first mobile two-way radios in 1923
  2. Radio Frequencies i.e. AM, Shortwave, FM, VHF and UHF
  3. Telecom i.e. IP companies worldwide


  1. Cellular Network 1G Analog Tokyo 1979, Europe 1981, US 1983, Australia 1987. They had a 007 prefix that dialled directly into the public switched telephone network (PSTN) using numbers first issued in 1981 to non-cellular "carphones". None of this infrastructure was cheap with the first Telecom mobile phone in Australia in 1987 costing $4250
  2. Cellular 2G Digital (GSM) Telstra in April 1993, Optus in May, Vodafone in October, using a 04 prefix. The cost of a Motorola phone had now dropped to $399. The Internet was still accessed over landlines, GPRS Internet not arriving until 2001
  3. SMS in Australia was first offered by Telstra in 1994 but similar to a pager service, so customers could only read messages, not respond to them. It followed the world's first SMS text message "Merry Christmas" sent on December 3 1992 by British software engineer Neil Papworth

    In 1995 Telstra, Optus and Vodafone began allowing SMS messages to be sent from customers mobile phones, but only between customers of the same carrier. It wasn't until April 2000 that the three carriers agreed to co-operate and launch inter-carrier SMS, which set off huge growth in usage. Telstra said between 2002 and 2012 the number of SMS messages sent on its network grew from 1.01 billion to 12.05 billion

  4. Wi-Fi 1999 short range wireless networking utilizing LBT-Listen (say 20ms) Before Talk (say 4s) and promoted by the Wi-Fi Alliance in the US. Based on WaveLAN, sold by AT&T and NCR and Lucent Technologies, following its debut in 1990. While the 900 MHz models and the early 2.4 GHz models operated on one fixed frequency, the later 2.4 GHz cards as well as some 2.4 GHz WavePoint access points had the hardware capacity to operate over ten channels, ranging from 2.412 GHz to 2.484 GHz, with the channels available being determined by the region-specific firmware. In Australia, the CSIRO developed its own prototype from 1992
  5. Bluetooth 1999 short range wireless pairing (up to 100 metres) utilizing Frequency-Hopping. Initially launched via Ericsson and IBM, plus Intel who came up with the name, and in 2002 Apple.
    Major player in audio streaming
  6. Cellular 3G (W-CDMA) launched by Hutchison (Vodafone) in 2003, Telstra in 2005, Optus in 2006
  7. Skype (VoIP telephony) in 2003 a fore-runner of Zoom. Runs on a centralized login server, Kazaa-like supernodes, and localized "buddy-lists". Grows to 136 million users in 2006, with links to wholesale international telephone carriers UK Cable & Wireless (Vodafone), US iBasis, and Level 3 (Lumen).
    Since 2011 a division of Microsoft
  8. Cellular 4G (LTE) 2011
  9. Miracast 2012 Wi-Fi Direct, Media Mirroring, also called Casting (Windows), Smart Share (LG), Chromecast (Google), Airplay (Apple). Devices attaching on their one-on-one Wi-Fi connection.

    With Windows 10 Creators Update released in March 2017, also known as version 1703, Microsoft implemented Miracast wireless projection of the Windows screen using the existing Wi-Fi network. It enabled, for example, the Smart TV receiving the realtime streaming of the Windows display and audio to be on a wired Ethernet connection, as well as Wi-Fi, with Windows prioritizing the faster connection

  10. Cellular 5G 2019
