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

LG User


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

SW Feature licenses also possible

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.
