Thelady I work with ordered one last week and it arrived yesterday. She was getting far far better download speeds than my semi-rural ADSL1, and NBNco are a pack of mongrels to deal with with Fixed Wireless, so I tried getting hold of one myself today...nothing listed.

Had an irritating time dealing with Optus' online chat people today who all insisted the B818 definitely was not available and the AC800S was the only option. They were very pushy, however that's a bad thing to try with me so it didn't go anywhere.


so i think the biggest thing people will experience between soethign like the B525 and this new B818, is an extra set of mimo layers. B525 = 2x2 Mimo, and B818 = 4X4 Mimo.

This extra set is apparent equivalent to 1.8 times the spectral efficiency, so i would imagine thats the biggest improvement.

So it should really help people with poor signal, as there is now a much better ability to work out what is data and what is not in laymans terms.

So i think this will end up being a good way to even out the spread of speed across a cell, meaning less favour to those closer to the tower, which is a good thing. it should be an equally shared system.


I agree somewhat, but for me, in the past, band locking has not only been required for selecting a good band, but more importantly for ignoring a band which is so bad it actually slows everything down, even when aggregated with good bands. It slows the whole thing down due to "channel state information feedback". So the most important thing to me is to be able to tell our modems to ignore things like B28 when we are near to a tower in a dense urban area.


So far, my upload speed has consistently shot through the roof through, which I did not expect. The B525 would hit about 8Mbps upload speed (my previous ADSL2 was 0.7Mbps, so 8Mbps was a hell of an improvement), but my lowest speedtest.net result so far with the B818 is 15Mbps upload. At its highest, it's cracked a whopping 32Mbps.


Haha. i had a giggle.

What bands were you on wiht the 525 and what are yo on now with the 818? any idea? Id love to find out f its due to better uplink ability through better uplink QAM, or if its a different band being used all together, or if its the addition of a new uplink band on the B818 using uplink carrier aggregation.


I tried enabling 2300MHz only with the B525, but I didn't seem to notice a difference. Top speeds were good, but pings bad. I can see the B818 has similar options, but I've just left it on Auto for now.


right so you didnt notice a difference so it was probably on 2300 all along. in which case, the reason you are probably seeing upload speed increase is the cat 6 routers (like the B525) didnt have 64 qam uplink, whereas this cat 19 does.


Optus must have done something in the last few days. I was routinely getting pings around 20ms to local (Perth) servers before, but now pings have blown out by a factor of 5 and speedtest.net thinks I'm in Melbourne!


The pings in speedtest are now going to melbourne and back (for whatever reason). thats what happened. SO it doesn't realy matter. In speedtest app, hit select server, and type in perth, and then visually look for an optus one. Pings should be back to normal.


Where are you?

At 8 km, a direction antenna tuned for the 700 mhz band would be your best bet. They would have said what they said, because such a thing isnt easily available from a shop nearby. HE is right that a standard panel or omni wouldnt help. but a directional antenna for this band will help alot.


Thats a good signal, an omni directional antenna like -3g-omnidirectional-mimo-700-2700mhz-antenna.html will increase that to -90 which is getting close to an excellent signal. Half the benefit of an external antenna is getting some height and distance from everything else in your house.


However i agree that you cant expect much better than 40 mbps on B28, but i recon u could posibly stop the drops down to 25mbps (heaven forbid :P) from being so severe, by keeping that XPD UP while maintaining gain.


That sounds like a different issue. If I ping an Aussie site like iinet.net.au, then yes it's 20-30ms, but my experience in general is that websites are no faster than ADSL2, with fluctuating response times (sometimes fast, sometimes it takes a few seconds to load). Seems to be worse if the website is requesting data from multiple servers (ads, etc).


On a different note, the B818 from Optus does not have a USB port. The Optus website advises that it does, but this is incorrect. Judging from pictures, the overseas model has USB, but not the one delivered to me from Optus. Just in case anyone was wanting to use it.


Telstra has more bandwidth on the tower but their plans are obviously not price competitive. One of the reasons we have gone with the large Optus plans is having a gamer in the house. This means that satellite ping times are untenable and we need a decent download capacity for the games themselves.


This is 4G not 5G. You won't see any sub 10ms pings on 4G, not even from Telstra. Even Telstra 5G doesn't get any lower than 10ms at the moment. Optus 5G isn't much better, because 5G is still a first generation technology, it hasn't matured yet.


I telephoned Optus Sales no 5G, the salesman told me I qualified for the offer, made the changes to the account, arranged a replacement sim which I got the next day activated it and had to contact Optus to deactivate the old sim.


What I'm saying is that there is no way I'm getting 19ms ping on 4G. Especially with Speedtest.net sitting there for 30 seconds "finding optimal server..." when it only takes 4 seconds to ping all those servers on ADSL2.


Quite a few of the servers have "issues" when testing from an Optus mobile based device, so probably what your seeing is it trying and then timing out, then trying again to find a working server.

On your ADSL based connection it does not have this issue.

Select a server manually and see what you get.


If you are on a 24 month contract, my understanding is you would have to pay out any balance owing on the modem.

I purchased my B525 modem outright from Optus, so I had no outstanding balance. The salesman just did whatever he had to do to get me on the reduced price and it was done.


The Sales people have better access, understanding of the system and how it works compared to the people manning the message system. My account number did not change, just phone number for the modem due to the new sim.


I highly doubt it. B818 should have nearly same outcome with B525 in your case.

The B525 has many issues because of its poor design. No any heat sink inside. So the performance of B525 is not stable for long time running, especially the 4G chip and WiFi chip.

B818 is a very solid 4G modem with more sophisticated and robust design.


So if you live within a good stones throw any of these towers (they have all 3 FDD bands) then consider the upgrade as a very worthwhile venture, but when you get the device, be sure to select 4G only no 2300 in the connection settings to force it to use these 3 instead of the TDD band 40, which suffers a bit in the evenings.

Towers with all 3 FDD bands on optus are here. ( as of Nov 2019)

-18069-map.kmz


but if your band 7 is being accessed from one of these towers, then maybe its not gonna help THAT much, as these ones have Band 7, but not BOTH 28 and 3. so these ones have a maximum of 2 FDD bands on the tower anyway. (must include B7 to make it onto this map)

-18069-map.kmz


nope, the cat 9 + devices can indeed to TDD and FDD aggregation together, thats correct, but what i was reffering to was the difference primarily between the 525 and the 818, which is the number of carriers is not limited to 2, as it was with the 525. thats all im saying.


That plus, the fact that when you are limited to 2, your best bet is usually 2 lots of B40, but when you are able to have 3, then band 7 is awesome because its an entire 20 mhz devoted to one direction and it doesnt get hammered by ppl further away because their devices cant hear it at those distances. Whereas B40 is 20 mhz shared between both up and down. So with lots of ppl streaming and face-timing and all the new modern day nonsense, B40 can get quite hammered by people on the uplink.


OK so ive been able to work out confidently, on an area by area basis, how many carriers of B40 are available in certain areas, and i can confirm, in some cities, its very rare for a tower to have all 4 bands (like perth). but in some, its practically standard now. (like sydney)

Ive been abel to do it with a combination of OpenCIll ID info and Mozila locations database data.

Anywhere where a node used in that area for B40 (perth example is nodes beginning with 17) where a sector has multiple Physical Cell IDs (PCI) per sector, those PID represent different sets of B40 that phones have been able to access. So its really limited to those areas where a decent 3-4CCA device has been used. So id say its not perfect but better than our guessing.


Remember my crazy maps are only focusing on B40 2300 mhz TDD, CCA channels.

Coz i just did Brisbane and the most B40s I can see being broadcast anywhere in the metro area is 2.

So either my methodology is completely flawed, or your talking about toal CCA carriers (as opposed to my b40 only) or there arent enough young whipper snappers in brisbane with 4CCA phones sending data to the source of this data, Or perhaps, you are getting 2 B40s from one tower and 2 more from another!

Here is Brisbane.

Big circle = 2 B40s, small = 1.

(edit : incorrect map, please ignore) See post a bit further down for updated map.


it always sais disable when idle.

go to a speedtest and while its running, return to that page and refresh it and be amazed :)

If not, report back and id liek to know where you are and what band the modem sais you are connected on
