Fixed Wireless technology first made an appearance back in the '70s, and since then it’s been quietly forging ahead in leaps and bounds as other – often more contentious – technologies have hogged the limelight.
But of course, the concept can sound confusing at first glance. How can you have both a network that is both fixed AND wireless?
Well, when you think about it, all ‘wireless’ communications (4G, 5G, Wi-Fi, satellite) will at some stage connect with fixed infrastructure somewhere. For instance, around 98 per cent of all international internet traffic travels along deep-sea telecommunications cables.
How does Fixed Wireless technology work?
Fixed Wireless networks transmit data over radio waves via small antennas acting as connectors, typically placed on the roofs of buildings.
Fixed Wireless networks have traditionally required large antennas to deliver slow and sub-par performance. By contrast, today the technology has advanced in range and performance by several orders of magnitude. In fact, recent improvements to Fixed Wireless have massively outpaced some residential NBN capabilities, including new mmWave technology that has the capacity to deliver residential customers with symmetrical upload and download speeds for the first time.
Antennas have also reduced in size from 1-2 metres to today’s average of around 30cm. This pivotal achievement means that gaining the necessary government planning approvals and physically installing antennas is much more straight-forward than it used to be.
What is Fixed Wireless capable of?
For the past several years Fixed Wireless has used mmWave (millimetre wave) technology, now supporting speeds in the realm of 20 gbit/sec. That’s 20-times faster than the 100mbit/sec some people are able to achieve over 4G today.
Millimetre wave sits between microwave and infrared waves, which is the band of spectrum between 30 GHz and 300 GHz. This spectrum can be used for high-speed wireless communications as seen with the latest 802.11ad Wi-Fi standard (operating at 60 GHz).
But what’s really interesting, and something many people don’t know, is that mmWave is precisely the same technology underpinning 5G.
A lot has been said about Australia's potential for 5G mobile services to provide enterprise-grade network connectivity and eventually remove the need for physical lines and cables. Yet as we all know, the roll-out has been slow and fraught with challenges.
And Fixed Wireless has been using the all-important capabilities of mmWave for several years.
