5G now also on Eir prepay
#21
Just got an Eir prepay sim for testing. Account says it is active. It won't connect to 4G. Tried router and 2 phones. GoMo sim gets 4G no problem. Any ideas?

I suggest trying the suggestions in this post. I ordered my SIM through their website and 4G was active when I received it through the post, so it's possible it may take a day (e.g. overnight) to provision 4G. Otherwise I suggest bringing it in a phone to an Eir shop to troubleshoot as you'll be able to show your GoMo phone with 4G and the other phone stuck in 3G.

I have continued using my Eir SIM in the router and noticed this evening it is no longer connecting to band 3, so my speed has dropped to about 30Mbps between band 20+28. I have not received a text for exceeding my allowance, so am not sure whether it's due to that or a problem with band 3 this evening. I'll know for sure over the next day or two as I reckon I'm very near 120GB usage, if not over. My Eir shows my usage as 104GB, but was last updated on the 9th, so they are slow to update.

Update: Band 3 returned shortly after posting this with the speed back to ~100Mbps. With no SMS yet, it looks like I'm not quite at the limit yet and that the brief band 3 disappearance was likely a mast issue.

Playing with the 2+3G settings didn't work although 4G would briefly flash up. Saw guy on Boards had same problem, Eir had to do something to his account which worked. Rang Eir, did network reset i think, working now, but had to go to 2G first.

That's great, seems like they didn't provision 4G from the start.

I have now, which I noticed when web browsing suddenly got sluggish.  At first I thought there was another signal problem until this SMS came in:

   

Make that "Further data usage will be subject to limited speeds."  When I download anything, it very briefly bursts in for a split second, then is throttled to exactly 5.0Mbps:

   

Uploading is throttled to exactly 1.0Mbps, hovering around 1024Kbps in the router traffic graph:

   

So basically, they throttle the download speed to match Clear Mobile.  Then again, even this throttled speed is still adequate for streaming YouTube and Netflix in HD with a single device:

   

One major issue however is with their upload throttle. In whatever they use to limit the speed, uploading anything causes bufferbloat so severe that even pings fail until the uploading finishes:

   

This basically means that video calling will probably not work properly once one reaches their fair use limit.  Despite Eir claiming there are "no limits" to worry about, I already know someone that manges to use up their 100GB allowance on 48 just between Facebook (~60GB in one month alone!), WhatsApp and YouTube on their mobile, so reaching 120GB is not that much more.

Edit: A bufferbloat test on DSLReports, first time I've seen it give a triple F rating: Big Grin

Ok, thanks Sean, that's good to know. So technically is actually is unlimited.

I was setting up that Eir sim in a house, testing speeds etc. Was also testing speeds on my phone using Gomo getting 130Mbps. Connecting phone to router on 2Ghz wifi getting 30Mbps. Thought something wrong with Eir sim until I connected up Nova mesh and got 130. When connected to router 5Ghz got 130 also. Knew 5Ghz was faster but didn't think it would have this kind of impact!

Indeed, there's a huge difference between 2.4G and 5G Wi-Fi. I also find the 5GHz band a lot more stable, particularly when just a room or two away.  2x2 MIMO also makes a big difference, for example, my previous HTC U11 phone had 5GHz 2x2 MIMO, which could get around 500Mbps with an iPerf3 test to a PC connected to the primary MW6 Tenda node.  My current Samsung A51 5G phone also has 802.11ac capability, but lacks Wi-Fi MIMO, so maxes out about 260Mbps with the same iPerf3 test. 

I did some final testing with my Eir SIM before switching back to Three.  By far the biggest issue is their upload bufferbloat while the connection is throttled.  It's not just pings timing out, any uploading taking place renders the connection completely unusable until the uploading completes.  Not even the Google homepage loads while OneDrive syncs new files to the Cloud:

While shopping, I tested to see how badly uploading affects mobile browsing and it also effectively kills the connection while uploading is taking place.  For example, I ran a 12MB upload test on TestMy in the Firefox App and throughout the upload, the Chrome App just kept failing to load anything, saying No Internet until the upload completed:

       

This means that if the phone is set to automatically backup photos and videos, taking a few photos or a video clip may prevent any other data usage until the automatic uploading completes. 

I also tested 3G.  It is throttled to 3.5Mbps down and 1Mbps up.  I retested in a few areas just to rule out a congested 3G mast.  4G gave the same 5Mbps down and 1Mbps up in multiple areas, so it's not based on network load.  My phone does not support 5G band 3, so was unable to test throttling over 5G today, but reckon it will be the same as 4G based on the mobile networks using 4G for 5G NSA.

While in Letterkenny today, I made an interesting observation - Eir prepay can still connect to 5G masts without an activate bundle, just no Internet access.  This is different to Three (not sure about Vodafone) which requires an active 5G add-on.  This means an Eir prepay SIM is useful for signal testing even without an active plan, as long as it has been topped up in the past 6 months to keep the SIM active.

I picked up two different band n78 masts in Letterkenny, one (PCI 727/728) along Pearse road heading for the retail park with the new Dunnes Stores, Homebase, etc.  The other (PCI 152) I picked up along the N11 dual carriage way that passes Toyota, Clanree hotel, Applegreen, etc. 

       


Unlike 4G, I noticed that the RSRQ can go all the the way to 0 with 5G.  The highest SINR I recall seeing was 22, also shown above.  I also noticed a 5G cell can pair with 4G primary cells in different locations.  For example, when it was using 5G cell PCI 152, I saw the 4G cell ID change between 43350, 42775 and 43524, all on different masts.  This can indeed make antenna positioning a challenge with the n78 band as the 5G may be coming from a mast in a completely different direction to where the 4G is being picked up from. 

I also figured out how to identify which Eir 5G masts are n78 enabled on ComReg's SiteViewer.  An n78 mast site will have two Site IDs with the same number, one starting with a two letter county code and 'NR' under the Services: 

   

None of the band n3 5G sites I've checked have a second Eir site ID with a county code.

While looking through some signal reading screenshots while in Sligo, I see that Eir supports 4G carrier aggregation while connected to 5G on band n78, in this example connected to band 1 as the primary 4G band with band 3 as the secondary band: 

           

Going by this post on Boards, the Huawei 5G CPE Pro 3 Eir supplies has 4G/5G selection disabled in its web interface.  This means those in a 5G band 3 area need to use a third party application to select 4G only, such as with LTE H-Monitor (Configuration -> Radio -> Network Mode drop-down).

Any technical reason why b28 and b1 can’t be aggregated on 5G or would it be a business decision? No n78 in my area and 5G (b20 and n3) can drop to below 10mb during peak. Changing over to 4G I get in excess of 60mb.

Possibly eir are planning to use 2.3 or 2.6ghz for 5G whenever that spectrum award gets resolved.

Hi Sean 
Another one for 
I have a eir prepay sim 5g enabled In my 5g phone,5g icon showing and all BUT when I do speedtests only getting average 35/40 dl and 10/15 ul I don't think it's true 5g connection have done various tests around town and same outcome.Its annoying paying the €20 and getting only 4g dl speeds.Any thoughts on this appreciate it thank you.

Going by your screenshots, that is just a 4G connection. Under the "NR Information" section, the "UpLayerInd: 1" indicates that the mast is announcing 5G is available. The "ENDC Status: Inactive" however indicates that a 5G connection is not established. You can see a comparison with my screenshots above where it shows "ENDC Status: Active" and 5G signal readouts below this line, which are blank in your screenshots.

The mast in your SiteViewer screenshot is a 5G band n3 DSS site, i.e. the 5G spectrum is shared with the existing 4G spectrum on band 3.

Which phone model do you have? If it's the Samsung A51 5G (which I have), this phone does not support 5G on band n1 or n3. It does support 5G on the much higher capacity 3.6GHz band n78. On the ComReg SiteViewer the Eir 5G band n78 sites have a two letter county code in the Site ID, e.g. "DL_4092".

Many thanks for your reply and information makes things alot clearer now.i have the same phone as yourself the a51 5g.Was in carrick on shannon few days ago and picked up 5g on the eir sim was on the outskirts of the town had like 3 bars and getting download speed 350/400 mbps, checked siteviewer and the site I'd is LM_4273 which tells me it's n78.When I'm there next il get more statistics.I also use the nperf app which is very good for showing signal / coverage of three,eir and Vodafone.

That was a decent download speed, looks like a quiet 5G mast also based on the AvgRSRQ reading of -1.  Cool

This confirms you were getting a proper 5G connection that time.  I also wonder if Samsung made a recent change with the 5G icon as it appears to show the same icon as the earlier screenshot where 5G is advertised by the mast, but with a 4G-only connection.  With my own testing, the 5G icon would present a solid white background:

With a new Eir 4G mast in Kilcar, I decided to top up and try some tests.  Despite what looks like a fair size mast clearly visible around the area, it appears to be operating at lower power than the Three mast that is not even visible from the road, yet both are in roughly the same location.  I cannot pick up the Eir 4G signal from my house even with an antenna!  To my surprise, I did manage to pick it up further down a field from our house.  Even then, the signal is about 10dB weaker than with Three 4G.  It did make for some interesting tests between MikroTik's LHG and a Poynting XPOL-2-5G antenna on band 20, which I'll post in a separate thread. 

Anyway, while in Letterkenny I tried a few speed tests on Eir 5G, the nearest town to me (despite a 1.5 hour drive) where Eir uses the high capacity n78 5G band.  The following is just outside the cathedral, 15th May, 12:21pm:
 
   

Signal readings - My phone (Samsung A51 5G) was aggregating 4G bands 1+3 at the time:

           

While at the Century complex about 6pm, I did a speed test comparison between Eir and 48. 

       

While most people don't need 100+Mbps on a phone, the high capacity 5G band does make a night vs day improvement over what I was picking up with 4G on 48 (Three network).  I tried toggling between the SIMs multiple times, but did not get 5G on 48 that day unlike my previous trips to Letterkenny.  

A few other observations since my previous testing:

Forcing 4G-only appears to work now.  The phone will sometimes show "No Service" as before, then the signal returns after about a minute.  Previously, it would show no service indefinitely until the phone was allowed to return to 3G until the network did a 4G hand-over.

Eir's network appears to periodically try switching devices to band 1 or 3 as the primary band where a signal is available.  However, if the signal is below about -112dB, the network still hands over to 3G.  For example, while waiting in the Lidl car park in Donegal, my phone would show band 20 with about a -100dB RSRP reading for about a minute, then band 3 with roughly a -110dB reading for a few seconds, then 3G for about a minute and back to band 20.  This loop carried on.
