Perth 4G Battle: Airport Slaughter

Alongside Melbourne and Sydney, Perth is the third Australian capital to have rival 4G LTE services from both Telstra and Optus. When it comes to performance, there's actually a clear winner, but the main lesson continues to be that 4G services vary hugely in the performance they can offer — even within the radius of a block.

This shouldn't be news, of course. Mobile networks are inherently variable; even moving from one side of the MCG to the other made a massive difference to the speeds and networks I got in a pre-Grand Final test. Yet many people remain firmly convinced that a given network will always be a better choice than the other in speed terms. The reality is rather more complex.

Perth provides an excellent example of how much performance can vary even with very slight changes in location (as well as a test bed for more complex 4G projects). In my hotel room in the Perth CBD, I was utterly unable to scare up a 4G signal from Telstra, and the 3G speeds it offered were low. They weren't so low as to be unusable, but there was a bigger problem: the signal would regularly drop out altogether. A slow network is annoying, but a network that drops out on a continuous basis is arguably worse. Optus' numbers were also fairly low, but it did achieve a 4G connection.

Assuming that demand might be a factor and that the building's architecture might be an issue, I performed the same tests very early the next morning (like many Perth visitors, I largely worked on east coast time, which meant I was hard at work at 4am). The speeds for Telstra were slightly better, but the problem remained. Optus' numbers were somewhat higher than the night before.

I'd have been convinced that Telstra 4G wasn't happening at all in this corner of town, but when I went downstairs after checking out and walked one block, Telstra happily offered me 4G. The download speeds were still healthily outgunned by Optus (also on 4G), but Telstra won out for upload speeds.

Having walked another block or two to Esplanade station, I decided to repeat the test again, since there wasn't yet a clear pattern. Telstra performed even better, again winning the upload speed test and performing at an extremely similar level for downloads (16.73Mbps versus Optus 17.48Mbps).

So my CBD experience suggested that Telstra performed well if you could get a 4G signal, but that was almost impossible to predict. It was a different story at Perth airport on a Friday afternoon. The airport was filled with fly-in fly-out mine workers, and the Telstra network was struggling to cope. There was no sign of 4G signal at all, and the 3G performance was incredibly slow. How slow? Optus' connection was 90 times faster for downloads than Telstra's.

Here's the full set of results. I've indicated where Telstra defaulted back to a 3G network rather than offering 4G; for all other tests, a 4G connection was achieved. Reminder: being on a 4G network is not in itself a guarantee of better performance; in some of my previous testing Telstra 3G has managed to perform better than Optus 4G in the same location. However, that wasn't the case here. For ping times, lower numbers are better; for upload and download speeds, higher numbers are better. Tests were performed using the Speedtest.net app, averaged over three results.

Provider Ping (ms) Download (Mbps) Upload (Mbps)
Hotel PM: Telstra (3G) 218 1.25 0.36
Hotel PM: Optus 92 4.00 3.93
Hotel AM: Telstra (3G) 118 1.94 3.74
Hotel AM: Optus 125 16.47 13.48
CBD AM: Telstra 77 3.61 19.31
CBD AM: Optus 125 18.30 14.03
Rail AM: Telstra 104 16.73 9.42
Rail AM: Optus 126 17.48 7.23
Airport PM: Telstra (3G) 329 0.17 0.24
Airport PM: Optus 75 15.49 5.02

Is there an explanation for this evident difference? Very possibly. Several Perth residents I chatted with while on this trip mentioned that the Telstra network appears to be struggling to cope right now. Fly-in fly-out workers are potentially a major factor here. Telstra's coverage of mining and resources sites is, by most accounts, far broader than Optus'. If you're working in those areas, a Next G phone is likely to be an essential requirement. But that means there's a high concentration of Telstra phones in the state, and virtually all those workers will pass through Perth regularly. When they do (as at the airport), the result isn't pretty.

None of those workers are likely to switch to Optus in the short term. If I was living in Perth, not travelling out into the regions and concerned with data speeds, Optus would look like a much faster and more reliable choice. But if I'd stayed in a different hotel, my conclusions might have varied again. Right now, I'd suggest the biggest priority for Telstra in Perth is improving airport coverage: that's a big potential audience getting done over for coverage.

    Seems like Optus are really going for the jugular based on your stats and it confirms my own personal belief that Telstra aren't worth paying the extra money for if you spend 99% of your year in the metro area.

    Out of interest - did you fly all the way to Perth to just do this test? If you are staying in a hotel, and waking at 4am to start work, I guess there wasn't too much else going on?!

      Just to clarify something Elephant, ".....Telstra aren't worth paying the extra money for if you spend 99% of your year in the metro area."

      4G lte is not available in "the Metro Area" through Telstra (I don't know about Optarse but I assume it would be the same).
      4G lte in Perth is ONLY available in the Perth CBD.
      Telstra aren't worth paying the money for (if you spend 99% of your time in the metro area) because they are overpriced poop. Not just because the network is congested.

      Wireless broadband in Perth is struggling to cope with the numbers no matter what network you go with. In the end it comes down to luck, how many people are clustered around the mobile node you're trying to connect with.

        Actually your statement about 4G LTE only being available in the Perth CBD isn't true. From personal experience I've managed to get a strong (19Mbps down, 23 Mbps up) 4G LTE connection in Innaloo on the Optus network. To be fair, this is the only place outside of the CBD that this has happened. But if it can happen there, perhaps it's happening elsewhere in the Perth Metro area.

        I wholeheartedly agree with your last statement about it mainly boiling down to luck.

        Just to clarify Embrace, Telstra 4G is available in the Perth metro area and not just the CBD. Visiting http://www.telstra.com.au/mobile-phones/coverage-networks/our-coverage/mobile-broadband/ will give you an indication of available areas. No doubt the coverage will expand quite quickly too.

    Optus doesn't fare too badly in south Western Australia, quite a lot of the time it is better than Telstra because everyone out country way are Telstra. So when you've hot optus signal you have the monopoly! :)

    Reason for Optus winning at the Airport:
    Pretty much every remote minesite only offers Telstra services. Telstra is standard issue for Company Phones on remote sites. Hence why Optus won by so much.

      Yes, that is what the article said.

    None of the 4G/LTE networks extend beyond ~10Km north and south of the CBD, so it's aaaaall useless to me, who lives about 22Km to the north... :(

    Not sure about your experience, but I work in Perth CBD, and get great download speeds on Telstra 4G. Outside my office I got 63ms ping, 48.96Mbps download, 16.34Mbps upload, and have had better ping. Telstra service in most WA areas are MUCH better than Optus who i've just changed from. Might have got it on a bad day...

      Did another speed test on the train on the way in this morning (near canning bridge/swan river), pretty impressive 74.88Mbps/21.79Mbps upload.

        Impressive indeed.

    optus only hard launched their 4g service in Perth a few weeks ago so there is probably not much demand for it yet. A lot of people in Perth tend to favour telstra because of the better remote coverage (this is reflected in other comments). I am with optus and I think there data service is terrible (in Perth metro).

      I tend to disagree. I was using a USB dongle on Telstra in Perth CBD last Thursday and I could not even access three different sites I visited. I tethered my Optus iPhone instead (3G also) and it worked without fail.

      Despite the above, it is obvious as Jivedoctor has pointed out above, coverage in the CBD and metro area is simply down to luck. Well, more like where you are at any one time, and how many people are using the same cell tower.

    Unfortunately in Perth one thing is CONSISTENT with the Eastern States: VodaFail just is terrible

    However, the solution in Perth is actually quite simple: Vivid Wireless. Borne out of Perth, the coverage and speed is phenomenal.

      I'm with Vivid at home and its pretty bad. Download speed is ok ~8Mbps, but the latency is what kills it. Even things like YouTube is hard to watch at times. But thats what they get when they offer unlimited at $75pm

      If I am not mistaken, Vivid sold it's wireless spectrum to Optus months ago. I can't seem them being around for very much longer.
