Consistant daily problem with 1800Mhz cell ( id 631557 ) in Lemu.

There is a constant problem with this tower. Every day between around 3am to 7am this tower goes totally offline leaving no 1800Mhz 4g coverage in our area. When will this be fixed?

Thanks, Adam

There is also an 800Mhz frequency available in Lemu, perhaps your device is set to use just the 1800Mhz and when it's not available you get no connection at all? However, I contacted the network management and the 1800Mhz frequency will not be turned off at night anymore. 🙂

This might be related with Elisa’s network optimization. Some of base stations shut down ”unnecessary” frequencies during night time. As most of the CPEs have automatic band selection they just switch to another frequency. So if the 1800 MHz is dropped they will connect to 800 MHz.

Thats all well and good but what if it leaves you with no coverage?

Contact customer services and ask if they can leave base station you mentioned on at night. It seems that you have only one frequency available normally and when it shut down you have nothing left.

Many thanks, it is indeed now on 24hours a day for 1800Mhz, perfect.

The 800Mhz signal used to be in our location but when the 1800Mhz signal went up in early summer the 800 signal changed (degraded). I have no idea why that happened, I did mention it in another thread a few months back, I assume the direction was altered slightly.

I suggest that 800MHz was tuned to be about similar in terms of coverage than 1800MHz. As you might know, lower the frequency is, better a signal penetration is. To make coverage somewhat equal (to make LTE-A, Carrier Aggregation work the best), they might have done some optimisation.

Also, there might be an another BTS in the neighbourhood/surroundings, and it was necessary to make 800MHz cell smaller in order to avoid interference and overlapping coverage with the neighbouring cell.

Nice to hear that the issue with 1800MHz is now solved.
