how can i calculate MHT but not from Traffic volume21st July 2008 at 06:35 #43783RichGuest
Can any one explain how to caculate convert Erlangs in to kbps.
Cheers!21st July 2008 at 12:56 #43784PanGuest
It is very simple:)
If you have a channel with 64 kbit/s (230400 kbit/h)throughput and your information source bitrate is 230400 kbit/h, then you can say that your source is creating load with 1 Erl intensity on that channel. Accordingly – 230400/2 = 0.5 Erl, 230400/4=0.25 Erl for this case.3rd March 2009 at 03:12 #43785Dennis ThamGuest
I thought 1 Erl = 64kbps and not 230400kbph3rd March 2009 at 12:19 #43786PanGuest
Hi, Dennis Tham !
It is dependent for what time period you are averaged your load. Usually in telecommunications it is one hour.16th July 2009 at 02:38 #43787CarlosGuest
the WCDMA system is a little different from GSM and others. In GSM, when you used to have problems with traffic demand, you really need to imply more TRXs. But in WCDMA the Transport network is very important and must be primarily verified. Suppose you have a growing traffic that is reaching the transmission BW, then the chosen QoS will be in charge of reducing this BW in order to keep loss and delay requirements. Then, my answer is that you must verify your system before start increasing HW.16th November 2009 at 17:09 #43788AakashGuest
What is the capacity for a BTS in erlang for a GSM and a CDMA business seperately??2nd December 2009 at 15:18 #43789Dennis ThamGuest
Thanks for your insight. Yeah, I understand now, 64kbps = 64 x 60 x 60 kbph = 230400 kbph….
Another question, do we actually consider the uplink or the downlink when we convert the Erl to kbps?2nd December 2009 at 16:13 #43790pixGuest
usually, we consider only the downlink, because it is the direction in which there is the most traffic.
so f the capacity is enough in DL, since it is symmetrical in DL and UL (capacity DL = capacity UL), it is plenty enough to carry the UL traffic.6th January 2010 at 11:46 #43791J B SinghGuest
how we can calculate IP bandwidth in kbps for 1 Erlang of voice traffic?15th January 2010 at 08:54 #43792Valentin GeorgievGuest
It depends on the coding you choose. Standart voice channel is using PCM(Pulse code modulation) with result 64 Kbps. But with other modulations you can lower the speed to 8-9 Kbps.24th February 2010 at 10:31 #43793DebasishGuest
