17Need for Carrier provisioning CDMA technology does not use SIM card for carrier/subscriber provisioning, so this information has to be provisioned on the modemThe carrier specific configuration on the 3G modem are:Modem ESN and Security KeysCarrier PRI and PRLModem FirmwareAdditionally a security information file (flat file) generated during modem provisioning that’s needs to be sent back to the carrierTo support a new CDMA carrier, there are 2 options:Create additional CDMA HWIC SKU and perform provisioning in manufacturingUse the generic CDMA HWIC and defer provisioning to Cisco partner/reseller
18Now, in practice Actual Bandwidth Values depends on the following Factors RSSI ValueECIO ValueCellular Medium shared among Multiple Users.Distance between Site to BTS Tower
19AntennaThe extended out-door antenna is meant to extend the reach outside the surroundings if the surroundings (lot of metal cages etc.) blocking the radio signal. But it can not improve the already weak signal.cell-site itself is breathing heavily (in case of extreme over-sbuscription and inadequate radio resource planning), the signal will fluctuate. In that case, even the extended antennas won't help
20What is the recommended Values of SNR and ECIO to declare site signal strength bad or fluctuating Or requires Diversity Antenna or Outdoor Antenna
21RSSI Recommended Values RSSI Recommended Values dBm or better RSSI means good reception and better through to -89dBm is considered to be ok with reasonable throughput to -99 dBm is bad reception and throughput will vary significantly dBm onwards, should expect loss of connectivity. if -99, will see modems are working fine : Short answer, Yes, beyond 90 - nothing guaranteed but have seen card working at -90s at times but with very low throughput and high delays.
22ECIO Recommended Value ECIO value as low as possible. Lab tests have indicated ECIO ≤-2 dB. If you observed a value of -7 or something similar, you might have a very noisy environment, which may in turn cause retransmissions of the packets, lower throughput, call drops, etc.

26Modem Provisioning Process Sierra Wireless provides a GUI based modem provisioning toolThe 3G HWIC allows direct access to modem via the diag portProvisioning steps:Boot up router with 3G HWICEnable modem access from diag port using an IOS command:test cell-hwic x/x/x usb-to-dm(Note: This requires that you have “service internal” enabled in the config mode)Connect the USB-to-RJ45 cable from the PC with SWFlash to HWIC diag portRun SWFlash on the PC which would download PRI/PRL/FW and create an entry in flat file (~10 mins)Send the combined flat file to the carrierPC with Sierra SWFlashSpecial USB to RJ45 cableHWIC in a Router

This program uses the CCT to program/configure modemsPackage - Configuration bundle of:Modem FirmwarePRL – Preferred Roaming List (provided by carrier)PRI – Product Release Instructions (aka modem NV settings)Flat FileOutput file created by CCT.

30Hands on SessionLet us Continue, How to install , Configure and Provision the CDMA Packages.
31Main Antenna vs Diversity Antenna The diversity antenna supports only downlink;The main antenna supports both uplink and downlink .Multipath is a form of RF interference that occurs when a radio signal has more than one path between the receiver and the transmitter. This situation occurs in cells with metallic or otherRF-reflective surfaces, such as furniture, walls, or coated glass. The diversity antenna ports are designed for spatial diversity, and the radio checks the other antenna only when it encounters errors.Contd..
32Diversity antenna should be used always wherever possible Diversity antenna should be used always wherever possible. Typically, when the signals are not good (worse than -69dBm ) and lot of interference due to surrounded by lot of radio sources, metal casings, metal cabinates, the ECIO value goes down. In such scenaro, Diversity plays an important role to improve the overall throughput.On what basis will decide to choose in door or out door or low antenna?For commercial deployments where the router is generally deep inside the buildings (in a closet or rack room), it is recommended to use external/outdoor antenna so the antenna can be placed out side the room/closet and can receive the unattenuated cellular signal. Recommended deployment for antenna is at the edge of the building (glass-wall or window etc.) or on the roof-top of the building for better reception.
33Site Survey ChecklistWhat is distance between Site to BTS Tower?.Volume of Subscribes over that region?What type of CDMA service offering by Service Provider?What is the RSSI (Signal Value) at the Place, where we kept router?.What is the RSSI Signal value at Outside?
