Getting 5G working. Is Sony 5G proper 5G?

Hi all,

In Australia at least, the current crop of Sony Xperia phones such as the 1 ii and 5 ii have 5G bands compatible with our carriers however I've not read of a single person being able to actually connect to 5G.

I'm on SEA firmware.

My wife just purchased an ASUS Zenfone 7 Pro and 5G worked out of the box for her.

Both handsets are not sold in Australia but hers works?

Has anyone else had luck connecting to 5G?

Pretty annoying owning a 5G mobile, that has the required bands, being unable to connect to 5G.

Cheers

Check if your Service Provider supports bands which Xperia 5 II supports: 1, 3, 8, 28, 77, 78
Zenfone 7 Pro supports these bands: 1, 2, 3, 5, 7, 8, 12, 20, 28, 38, 77, 78.
So it could be your Service Provider supporting bands which are not supported by Xperia 5 II.

No, Optus uses bands that the Sony Xperia 5 ii should support.

From this website.


Optus uses;

B3 (1800 MHz)20 MHzActive
B7 (2600 MHz)20 MHzActive

Optus 5G
5G caught a lot of people in the technology industry by surprise. Expectation was that we wouldn't see 5G implemented until 2020 at the very earliest. But the tech industry moves faster than any other and 5G is already here. The key Optus band for 5G is n78 (3500 MHz) which it has deployed with 64T64R Massive MIMO antennas. Optus' 60 MHz channel means it can pipe around an extra gigabit on top of its existing 4G LTE network.

3.5 GHz does have a limited range, but beamforming technology has been demonstrated to provide similar range to that of 2.6 GHz. With 5G there aren't a lot of options as far as traditional external antenna systems go, 5G is such an advanced technology that we can't use old fashioned coaxial cables and patch leads. All 5G units worth their weight are all-integrated ODU style.

In the next year or two we'll see the introduction of mmWave 5G on Optus, who are looking at n257 (26 GHz) as their main millimetre-wave band. This is where things will get very interesting, and incredibly fast with trials showing data rates as high as 70 Gbps. Picking a 5G integration partner who understands the technology is going to become more and more important as the industry progresses.

Optus moved very fast on 5G. Our expectation is that Optus 5G will continue over n78 (3500 MHz) for the time, but an eventual refarming of its extensive 2300 MHz holdings is a near-certainty. Optus secured 98 MHz of 2300 MHz spectrum when it acquired Vivid Wireless in 2012 and portions of the spectrum are currently used for B40 LTE for the company's 4G Home Broadband service. It's R-Spectrum's prediction that an 80 MHz n40 5G carrier will be implemented in the coming years - possibly making the Optus 5G network the fastest in Australia.

Optus officially launched 5G services in November 2019 with an initial 290 sites, and expanded to 1200 as of March 2020.

Looks like all bands you mentioned in above table are 4G(LTE) bands. For 5G only n78 is supported by your provider so check if your phone has support for this band. I believe you have XQ-AS72 model so check if you have this support and you are selecting correct network from Preferred Network.

Yes but the XQ-AS72 supports n78
