Synchronization GPS used as the source for frequency and time synchronization
System Module contains an oven controlled oscillator (OCXO), which provides a
highly stable clock even if the GPS receiver fails or GPS is temporarily unavailable The GPS antenna with integrated receiver has to be installed outside for satellite
visibility and is connected directly to the Synchronization Input of the System Module
DC power for the receiver is supplied through the combined power/data cable
Timing over Packet (ToP) is a feature candidate for Release 2
Note: GPS solution under study

Flexi WiMAX BTS Licensed SW Features(Rel 1)
Flexi WiMAX BTS Operating SWIncludes one activated Ethernet interface
RF capacity upgrade licenses (Application SW)3Mbit/s, 6Mbit/s, 9Mbit/s, 15Mbit/s upgrade steps
Aggregated User Plane throughput capacity in BTS System Module
Total capacity is cumulative, e.g. 18Mbps can be composed of two 9Mbps licenses
Transmission licenses (Application SW)Additional 10/100 Ethernet (FTM) Interface license
Other Application SW:BTS V-interface license
Enables DSL operators to connect WiMAX BTSes directly to BRAS (Broadband Remote
Access Server) via V interface protocol
H-ARQ (Hybrid Automatic Repeat Request) licenseSignificant coverage/throughput gain due to fast re-transmission of packets and due to
combining of the information from earlier transmissions of the same packets.
Subscription based Rate limiting (UL in BTS, DL in ASN GW)Enables operator to limit peak data rate on a per subscriber basis. QoS parameters are
received as a part of user profile during authentication phase.

Element Manager for local or remote
control PC based element manager, Flexi WiMAX BTS Site Manager, is used for local and
remote management of the BTS
Flexi WiMAX BTS Site Manager can be connected:
Locally to the Ethernet port of BTS
Remotely from the O&M Server (OMS) or NetAct
O&M traffic is carried within the BTS backhaul link via Nokia BTSOM protocol
Main functions of Flexi WiMAX BTS Site Manager:
BTS commissioning
BTS supervision (alarms, block/unblock) BTS maintenance with SW download
BTS testing
Autoconnection makes commissioning and integrating fast and easy
Properly installed, but non-configured BTS can be accessed by Flexi BTS Site Manager remotely
Less work required on site
File based commissioning is also supported Site Configuration File (SCF) from NetAct Planner can be loaded into the BTS with Flexi WiMAX BTS Site
