GuestHi, Can any body provide me the formula or methodology to convert site througput to Erlangs ?

can any one tell me how to convert megabytes traffic to erlang?NiceGuY
GuestI 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..

Guesthello, i think in UMTS there
Traffic (erl)*12.2 kbit/sec.*3600/8 = Kbyte
12.2 AMR bit rate
if video
eraling *64 k bit/sec *3600/8 Kbytes
bill
Guesthow to convert payload in Megabytes to Erlang???

GuestHow to convert GB to Erlang
Gyan
GuestI 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 TerminalDebashis
GuestCan 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)

Guesthi,
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.

Guest1. 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 ?

GuestTraffic (volume) = Traffic (Erlang) * 3600 * Bearer BR * AF
Bearer BR = Channel Bit Rate
AF = Activity FactorFor voice services most vendors recommend to use 0.6
For data services most vendors recommend to use 1Ahmed Elshafie Sir ELkhatim
Guest1 erl = 28.8 MB
In RAN following Erlang B Table
As 2% blocking
1 erl = 4*16 Kbps*3600/8/1024 = 28.8 MB
