Wireless Application Developers Guidelines for IoT

BY Michelle Telstra 16 July 2020

The Internet of Things (IoT) is an all-encompassing suite of technologies, with dozens of options for connectivity. Whether yours is a content-heavy urban challenge for drones and driverless cars, or a rural deployment of environment sensors, the network technology you chose to connect your ‘things’ to can make or break your solution whether that’s 5G or NB-IoT.

With sensors becoming cheaper and easier to access, we are seeing developers from all industries and levels of experience extending their understanding of operational environments for business and personal gain. And we think that’s great! The future of technology should be shaped and created by diverse developer communities, we’ve already got over 3 million devices on our network!

So we’ve created a comprehensive guide for Wireless Application Development to:

  1. educate developers about Telstra’s mobile network;
  2. encourage developers to produce network more efficient “impact friendly” applications i.e. applications that don’t impose an unnecessary strain on the mobile network; and
  3. overall enhance developers’ experience of the network.

It is important to understand how to best develop for our mobile network. Your design choices can have significant effects on how well your application works, as well as potentially give your product or solution a competitive edge and improve its performance, by improving things like its feature set, longevity and compliance to industry standards.

For Narrowband IoT deployments specifically, a common problem we see is the over-use of wireless network resources unnecessarily. For example, co-scheduling hourly reports for a few devices is not detrimental (unless you have significant battery or data constraints), but when scaled to hundreds or thousands of devices in the same radio cell, sending data at the same time, every hour of every day, the aggregated load may be constrained by the limited bandwidth of NB-IoT and Cat-M1 network. Can you stagger or randomise the polling times of your devices? Can you report less frequently to get the same end result? You may save considerable battery and data usage along the way!

We encourage you to take the time to read and understand our guidelines. Although we think the full 37 pages is an important read, focus on section 7.3 for Network Connection Efficiency. These guidelines may not cover everything, but they could help you avoid common inefficiencies in your IoT deployments. Best of all, they are free! You can download them from here.

Happy Developing!
