How many E1 links per site are required to support HSDPA services up to 7.2 Mbps rate in case of Ip transmission ?

Thank you

for Iub planning, it's easy way at least to guarantee 7,2Mbps so minimum on your IuB transmission must be (2Mbps x 4) = 4 E1 dedicated for one user HSDPA but in detail calculate to accommodate overhead is must digging my literature first :p

I also calculated 4 E1, but vendor is requesting 8 E1, are you sure 4 E1 will be enough ?

Thank you

as I said before, I'm sure if your services just for one HSDPA user not consider with signalling and others traffic (CS and PS), but 8E1 very unbelievable to request for

The 8E1 requested are for HSDPA + R99 CS & PS all together.

Hi bro, i will make some simple review :

1. HSDPA user allowed let's say 64 user will be guarantee until 512 kbps
=> 32x384kbps = 12,3 Mbps (4E1)

2. PS R99
- PS 64 x 10 = 640 kb
- PS 128 X 2 = 256 kb
- PS 381 x 1 = 384 kb

total = 1,3 Mb

3. Voice : 200x16kb = 3,2

so, depend your planning guidance about serve the all services

Depends on the amount of user lic in HSDPA and also the CE UL & DL you will have.
Initialy we start with 4E1 or 10mp IP RAN Ethernet for a 16users HS and 192CE. When HSDPA traffic increase then you add user lic and CE.

depend what's vendor using, anyway CE not related with throughput but code HSPDCH that you set in each sector

Is there any rule of thumbs for this IuB planning?
such as:

HSDPA throughput:
3.6 Mbps
7.2 Mbps
14.4 Mbps
21 Mbps
etc..

Iub dimensioning will depend on the peak HSDPA throughput you plan per site on RF: this should be defined by the radio team for the RF dimensioning (base band board). For the corresponding Iub throughput, you need to add some overhead that will depend if you use IP or ATM, but typically around 20% overhead for HSDPA.

Hi,
Atleast 6 E1 to reach 7.2 throughput, around 1.8M available per E1.
