Equipment swap (Huawei/Ericsson) eNB 12874?

Hi.

On Monday mast went down and its been suggested that it might have been because Three were doing a Huawei/Ericsson swap out.

I've attached some pictures of what's up there now, so maybe someone who knows could comment of what the kit is?

Weirdly, now its back up, my signal strength and sinr have dropped which is odd and annoying. Signal strength dropped by 20dB and sinr by 10db to 25dB.

Here's the images I took this morning. I've included images of the other larger 5G antennas.

Thanks for sharing Bigyinuk, hope my signal strength doesn't drop after saying goodbye to the Huawei antennas, as it's nearly non existant as it is. :rolleyes:
 
Looks like its the antennas on the right that have been changed, since they're the ones that look new?
From experience, typically I find its EE who occupy the right hand of a Three/EE antenna pair.

Which provider are you with - I assume Three - as eNB 12874 doesn't exist on cellmapper for EE, but does for Three (in Plymouth)?

A SINR drop could well happen now that EE have replaced their (presumably aging) hardware for shiny and more powerful new stuff.
Which metric are you meaning by 'Signal strength'? RSRQ or RSRP?

I'm with Three. On the MC801a stats it doesn't say whether its RSRQ or RSRP, just "5G signal strength"
 
The long panel antennas aren't usually swapped out, it's only the smaller ones at the top. My first thought was that it was the one on the left that has been swapped because it's the only one without an RF warning label on the front but the antenna below it looks like it belongs to EE. Can you confirm the colour of the middle labels on the feeders connecting at the bottom? The pic is a little to low res to see here but if they are yellow then that is definitely an EE antenna.

Remember as well that it's not just the antennas that have been swapped. There will be new fibres, the breakout boxes will have been reconfigured, new radios and new baseband units at ground level.

The antennas on the left have yellow labels on the middle connections, so they must be EE, in which case the shiny new antennas on the right must be Three's, and presumably Ericsson?

Disappointing that with the swap I'm getting lower RSRP and SINR. Difficult to tell if the speed is affected as it does vary quite a bit. I think I'm getting faster speeds on my S20FE phone than with the ZTE.

Amusingly I had a vendor swap recently, I'm very bad at identifying vendors but I had my local mast get boosted from 130mhz to 140mhz though sadly that hasn't helped me break my 2.1Gbps record on it

Testing the vendor swapped areas around here i am seeing lower signal levels, like others and if anything performance is worse, but that might be just a coincidence given the weather and amount of people out.

Just the small antenna at the top will be Ericsson, the big one will likely be a normal passive antenna most likely manufactured by Commscope so there is no need to swap that.

The reports of the connection being worse after the swap is interesting. I have heard opinions that the Ericsson kit isn't generally as good as the Huawei kit it's replacing so there maybe some truth in that.
