Scope

Confidential

Singapore 19-21/9 2014

•To cover Pits grandstand and village

stage , where concert is held

•Nokia small cell deployed on LTE

band 7 (blue cells) which is co-

channel of existing neighbouring

macros (macros in the vicinity on

both band 3 (red cell) and band 7 co-

located)

•Supports LTE 2600Mhz band 7

20Mhz channel bandwidth


Details

• All existing LTE macro eNBs are non-Nokia,

• Most macros have LTE band 3 (red cell) and

band 7 (blue cell) colocated

• Nokia small cells (Pits 1 & 2, GP 1 & 2) use

same LTE band 7 (blue cells) as co-channel to

surrounding Macros

• Nokia small cells were installed between

2.5m and 10m high as compared to 29-42m

high macros nearby

• Nokia small cells transmits 5W output power

compared to 20W from Macros. One sector of

Macro near pits was powered down to 10W

during F1 event

• Transmission backhaul is limited to 100Mbps

as provisioned by the customer network

Confidential


Execution

• RF planning for peak load handling, KPI agreement with customer

• Hotspot Identification and site selection, ensuring power & backhaul availability; site acquisition by customer

• Cost effective deployment : Cells mounted on the existing stairway structure of F1 GP office. No civil work required.

• Installation for each site completed in One day, integration & commissioning in one day

• Co channel deployment in a MV environment – Complete MV interface verification in lab to address all potential contingencies

• Real time monitoring, load balancing and optimization to ensure KPI adherence
