Hi, Can any body provide me the formula or methodology to convert site througput to Erlangs ?3rd February 2009 at 18:25 #55582nitinGuest
can any one tell me how to convert megabytes traffic to erlang?4th February 2009 at 10:08 #55583NiceGuYGuest
I think there is no formula to convert Megabytes traffic 2 erlang since the Erlang is a unit of measurement of “intensity” of voice traffic, not a measure of saturation throughput of a connection.
Unless there is an extented definition of “ERLANG”..
Any additional clarification will be welcome..

hello, i think in UMTS there
Traffic (erl)*12.2 kbit/sec.*3600/8 = Kbyte
12.2 AMR bit rate
eraling *64 k bit/sec *3600/8 Kbytes15th November 2011 at 11:42 #55585billGuest

How to convert GB to Erlang6th April 2012 at 10:22 #55587GyanGuest
I think NIce Guy is very right , there is no direct calculation for converting Data Traffic to voice traffic or vise versa.
all This calculation found in Internet is for Voice over IP or simple term when channels/TC are very fixed ie 1 or 2 ch/TC, may ch having capacity to deliver 64 Kbps, can calculate the erlang to Kbps.
but when throughput is depend on, dynamically used Time slot and depend on request of Terminal12th December 2012 at 10:27 #55588DebashisGuest
Can anyone let us know….
For 2G/3G voice we should take 12.2 Kbps & 3G Video 64Kbps while calculating for GB conversion.
Or its has be doubled…say instead of 12.2 Kbps it it should 12.2*2=24.4 Kbps (UL& DL combined)13th December 2012 at 22:05 #55589pixGuest
Downlink and uplink are using different “dimensions” (frequencies), so you can’t add them up.
It’s like trying to add time to space.
Jim, beam me up.20th January 2018 at 02:31 #55590jenoGuest
1. can anybody plz provide the difference in erlang value and MB value in data units.
2. is it correct to use erlang unit in nsf and eupan network
3. if “the Erlang is a unit of measurement of “intensity” of voice traffic”
does it takes other data also ?23rd November 2018 at 22:36 #55591Haroldo Manoel DornelasGuest
Traffic (volume) = Traffic (Erlang) * 3600 * Bearer BR * AF
Bearer BR = Channel Bit Rate
AF = Activity Factor
For voice services most vendors recommend to use 0.6
For data services most vendors recommend to use 1
