We are using full ZTE PS solution with DT function enable. Is anyone can help to identify what can be the issue ? BR, Djo 16th May 2013 at 18:18 #69049 pixGuest hi djo, which system is it ? 2G, 3G, 4G ? what are the throughput values you are measuring, exactly ? basically, you’re having low dl throughput. So check your congestion : air congestion, transport congestion, licence congestion. regards pix 20th May 2013 at 09:54 #69050 brotherGuest how much big is dl? do you test dl and ul in same location or it is mobile test? what is signal strength and quality? also please write which system is it? 1 unclear question returns lots of questions 🙂 21st May 2013 at 16:15 #69051 DjoGuest hi all, @Pix, the system is 3G. To give you more info, the UL is about 640 kbps and DL about 242 kbps which is not good. i’m going to check if we have any kind of congestion you suggest to check. @Brother, we are using fixe system to test and the signal is about -79 dBm. BR, Djo 21st May 2013 at 18:37 #69052 pixGuest djo, yes, start by checking the CE congestion (channel element), the dl power congestion, the dl code congestion, etc. If it’s not that, then check Iub congestion. Are you seeing that on only one cell, or on all your cells ? Regards Author Posts Viewing 5 posts - 1 through 5 (of 5 total) The forum ‘Telecom Design’ is closed to new topics and replies.
