BTS can have several code shared schedulers which makes possible to configure e.g.... 4 and 6 sectors sites with 2x80 CE allocation. Provides fully flexible 10.8 Mbps data rate to be shared among up to 3 cellsIf two cells are empty, one cell can use all 10.8 Mbps, radio conditions permittingIn low usage scenario (e.g.. active users in only one cell) provides identical performance as dedicated HSDPA scheduler per cell

• HSUPA activation requires a "fixed pool" of 8 CE when activating the feature.• Depending on the total amount of free available CE (#licenses and installed HW capacity),

the traffic load, BTS Resource Manager can dynamically allocate additional BB resources for HSUPA.• A max. of 160CE can be utilized by HSUPA. In case of conflict with R99 RT or NRT traffic needs, BTS Resource

manager will reduce the amount of BB resources available for HSUPA.• Each user can reach max 2.0 Mbps• Please Note that HSUPA requires HSDPA for DL. • In addition to the CE consumption for HSDPA and HSUPA activation, 1 CE for signaling is required per user.• Rel2 HW HSUPA dimensioning to be defined• Note: Softer HO overhead is included in the table, similarly as with Rel99 DCH

Coverage Planning with Flexi(Inc. Performance Measurement and Comparison with UltraSite)


Radio Planning Principles – much easier with Flexi

Make sure that there is enough coverage• Low drop call rate with good quality

Put sites close to the users• No blocking if all cells collect some traffic• low Interference if UEs are near to the cell

Avoid unnecessary overlapping with the cells• low interference level • High throughput for PS data• Low Soft handover overhead

Wall installation Pole installation Pile/Floor installation

Faster, more economic Site Acquisition &

rollout with Flexi BTS


Flexi has better Link budget with smaller cable loss (typ. 3 dB) and better Rx sensitivity performance

Due to the very low system noise figure in Flexi BTS, its RX sensitivity is approx. 1 dB better than with UltraSiteIt is possible to have 2..4 dB smaller feeder cable loss with Flexi if RF module is located close to the antenna Normally MHA is not used with 1..2 dB cable losses or with RF –head solutionIf Nokia MHA is used, no separate bias-T’s are needed since MHA power feeding and control is integrated into the RF module

• Link budget Example with 30 m height, 50 % UL load with 95 % indoor coverage in urban area (15 dB indoor loss)

• Note ! Here the sensitivity is calculated for the Static Channel with the BER target of 0.1 %
