View Full Version : increase speed for HSDPA to 6Mbps
Dear expert 3G, now in my country have problem with HSDPA no height speed (500 kbps to 1Mbps)
does every one know how to change which one parameter In RNC can increase speed up to 6Mbps (my country use product Huawei)
can all expert help me please

Have you checked the sim profile in the HLR
how many codes your company bought for license
dear friend
my company bought 10 codes for license

you can not achieve 6Mbps for 10 codes of licenses

What is the Bandwith in IUB interface?, in the RNC is active the license for 7.2Mbps may be the cause for low HSDPA speed

10 codes should give 7.2 if you use 16QAM modulation and Iub bandwidth is sufficient
Also check the number of HS users per cell is not having an impact

I think 7,2 is just an approach of theory, it's need an ideal condition, such as propagation, lower losses and so on, and then number of subscribers serving by cell, if you're alone perhaps you could got it. anyway, how about the license of codes?, I don't understand about it..

absolutely can not provide 7.2Mbps with 10 codes. (assume that transmission is good enough)

for transmission my company provide 5 E1 for node B and use 16QAM modulation
Please all expert help me urgent

Is this commercial network or test site?Because codes assignment for non-hs services has more priority over hs.First of all you should determine if this radio limitation or transmission.Check the transmission capacity for non-hs.Or could you provide Virtual Channels configuration?

with 10 codes license you can achieve 7.2Mbps

Recommendation is 6E1 but 4E1 should do the work as well.

Check the attached dump for HSDPA configuration.
/Karim
HSPDSCHMAXCODENUM=10, HSPDSCHMINCODENUM=1, HSSCCHCODENUM=4
--->
HSPDSCHMAXCODENUM=15
HSPDSCHMINCODENUM=10 or 5 depend on cs trafic
HSSCCHCODENUM=1
Check the attached dump for HSDPA configuration.
