LG
Flexi BTS Licensing principles
Pool license concept
• Operator orders in advance a bigamount (e.g. need for 1 month rollout)of unallocated licenses
• NetAct operator distributes licensesduring NE integration via NSN LicenseGenerator (LG)
• Simplified logistics, reduces site visitsfor capacity expansion
SAPOrder e.g.
1000 CE’s

No floating licenses
• BTS licenses tied with the physicalSystem Module HW, NOT with the site.
• When you move the box you alsomove the licenses with it.
Long term licenses
• Exception: also short term licences forchannel capacity

Number of Simultaneous HSDPA users
• HSPA traffic uses shared channel where the peak rate throughput isshared by all users in the same cell.
• When the number of user's transmitting data simultaneously increases,the average throughput per user decreases.
