EDGE data speed?

Hi,

What is the data speed the EDGE offers..
and what exactly is the enhancement it offers?

regards.

Re: EDGE data speed?

EDGE provides up to three times the data capacity of GPRS.
EDGE can carry data speeds up to 236.8 kbit/s for 4 time slots (theoretical maximum is 473.6 kbit/s for 8 time slots)
The 'enhanncement' is  a new modulation scheme called 8-PSK and produces a 3bit word for every change in carrier phase.
This effectively triples the gross data rate offered by GSM.

Thanks leivue,
This is what I was looking for exaclty.

Hi there,

Lets take a Cell where 3 TRX are there.

1BCCH+1SDCCH+22TCH.

How many TCHs we have to allocate for EDGE or is it shared ?
If it shared can we have a FIXED Rate as minimum (Like allocating one/2 TS always).
When requirement touches more than this can we share with Normal TCHs.

And Howmany TS needed for Signaling ?

Enhanced Data rates for Global Evolution

Enhanced Data rates for GSM Evolution (EDGE) (also known as Enhanced GPRS (EGPRS), or IMT Single Carrier (IMT-SC), or Enhanced Data rates for Global Evolution) is a digital mobile phone technology that allows improved data transmission rates as a backward-compatible extension of GSM. EDGE is considered a pre-3G radio technology and is part of ITU's 3G definition.[ EDGE was deployed on GSM networks beginning in 2003 – initially by Cingular (now AT&T) in the United States.

EDGE is standardized also by 3GPP as part of the GSM family.

Through the introduction of sophisticated methods of coding and transmitting data, EDGE delivers higher bit-rates per radio channel, resulting in a threefold increase in capacity and performance compared with an ordinary GSM/GPRS connection.

EDGE can be used for any packet switched application, such as an Internet connection.

Evolved EDGE continues in Release 7 of the 3GPP standard providing reduced latency and more than doubled performance e.g. to complement High-Speed Packet Access (HSPA). Peak bit-rates of up to 1Mbit/s and typical bit-rates of 400kbit/s can be expected.
