Cellular Connectivity

As demand for ubiquitous connectivity for IoT devices gets ever stronger, cellular networks can deliver reliable and secure IoT services using existing network infrastructure.

Get the right cellular connectivity, for the best IoT application performance.

The core technology used today for M2M/IoT in Australia/NZ is LTE (also known as 4G) with all local operators providing networks.

LTE has two diverging technology branches of technology:

  • LTE Cat 1 to Cat 18 offer high speed data throughput, ideal for primary internet and high-speed data e.g. video needs, office connectivity over cellular
  • LTE Cat M1 and NB-IoT: LPWAN LTE (low-power, wide-area) deliver a new class of cellular connectivity specifically designed for low-speed, wide coverage IoT /M2M applications using very low power to communicate

5G technology is also increasingly being rolled out and again this has two paths. The core 5G networks offer even faster speeds than current LTE, at least in built-up areas. In addition LTE CatM1 and NB-IoT can migrate seamlessly to remain current in 5G networks providing very long network life for customers needing to plan to 15+ years of operation

LTE High Speed

(up to Cat 18)

  • LTE is ideal for M2M and IoT applications including those that require video/data streaming and providing primary internet connections
  • Offers speeds from around of 10 Mb/s downlink and 5 Mb/s uplink. For Cat 1 all the way up to 1.2 Gb downlink /211 Mb uplink at Cat 18

LTE Cat M1

  • One of two LPWA standards over LTE, LTE Cat M1 provides a low power broad coverage connection with speeds of up to 1Mb downlink/uplink, ful mobility and support for VoLTE voice.
  • Cat M1 is ideal for IoT /M2M applications needing to send more than bytes of data per session/day


  • This LPWA LTE standard is designed specifically for static IoT applications for indoor and very wide area coverage, with long battery life. It is suitable for applications sending very little data per session/month (think of SMS message size sent a few times per day) It does not support mobile applications.
  • Data throughput is very low at around 26 kbit/s downlink


  • 5G (fifth generation) is the latest cellular technology being rolled out by  Australian / NZ operators.
  • High speed 5G offers far higher download speeds and lower latency than LTE, opening up new markets for wireless.
  • In Australia all three networks are rolling out 5G (Telstra using bands N5/N78/ (850 and 3500 MHz), Optus using N40/78 (2300/3500 MHz) and Vodafone using N28/N78 (700/3500 MHz).
  • The 5G standard also incorporates LTE Cat M1 and NB-IoT as IoT components of 5G giving those technologies very long life in market (at least until 2035) for IoT roll-outs.
