How to improve HSDPA Accessibility

Hi Guys

Any one know how to improve HSDPA accessibility due to UE fails? No overshoot on that sector, bad HSDPA accessibility on sector 2. UE Fails high on sector 2 second carrier about 3,287.

hi friend
- In my system UE fail may due to: UE problem ( USB internet), Radio condition, RF Module fail.

Most the problem is RF condition UE and power capacity

Hello Adele,
you need to understand that there is no radio link establishment for HSDPA similar to what we have for R'99..... there are maximum 15 X SF16 which could be scheduled and shared among users.
But there are ADCH which needs to be established when HSDPA connection is established which is used for signaling and it is R'99
So the problem could establishment of ADCH besides the number of users could be subject of license and limitation of admission control... the baseband processing must be allocated as long as HSDPA connection is valid o lack of basebande processing power can degrade the HSDPA accessibility

What I can see from your stats... you have too many HSDPA call requests on 2nd carrier ( I guess so it is not very clear). SO YOU NEED BALANCE HS requests in different carrier layer
So imagine you have lack of code, power, baseband processing power or high RTWP which can end up to low HS accessibility

cheers
