It is planned to lock 50% of TRXs in all sites, during night hours, to reduce electricity consumption.will it work??4th July 2012 at 18:43 #68384pixGuest
most vendor offers a facility called “dynamic power saving”, which will dynamically shut down the timeslots which are not used.
I’m not sure you need to lock 50% of your TRX every night anymore, in 2012.
Otherwise, yeah, sure, that will work and should be considered as a good alternative !
Go green !

If i lock 50% TRX ,will i get 50% savings?5th July 2012 at 15:58 #68386SHELDONGuest
I doubt you will get 50% savings.
You have to recognise that it’s not only TRXs that consume power at the site. You also have stuff like airconditioning, lighting and fans in the RBS.
The percentage of saving when you lock 50% of your TRXs is quite difficult to calculate, but I’ll guess a value in the range of 10-20%.5th July 2012 at 18:53 #68387pixGuest
and there is a risk that one morning, the unlock is not performed properly… so you have to check each site one by one… oO
i’m 100% certain that your vendor provides this feature already !5th July 2012 at 19:27 #68388DanGuest
failed results are saved as txt , so checking it would solve that.Thanks Pix and Sheldon6th July 2012 at 18:22 #68389TanujGuest
Yes this feature is present in almost all new equipment nowadays, in Huawei 2G its called Dynamic Shutdown, but many times the trx does not get unlocked itself so we have disabled this feature in our NW11th July 2012 at 02:31 #68390DanGuest
Weve started the lock/unlock process but some BSCs are showing issues like one way speech ,after unlock:-(11th July 2012 at 19:28 #68391pixGuest
ooops… that’s bad then ? on top of that, one way speech is very difficult to diagnose… (i can detect it because the tch duration is very short : ppl are hanging up quickly)
does it disappear when you reset the TRX ?
which vendor are u using ?
tanuj -> dynamic power saving is (generally) not shutting down the whole TRX, it just shut down the amplifier during the timeslots which are not used.
of course, it might work differently in huawei.

Its Huawei , in dual band sites we are experiencing the speech problem.Once the site is reset ,problem is solved.BTW dynamic power saving feature is there ,but as of now no license:(12th July 2012 at 09:40 #68393rskGuest
