  16. CDMA Service • 1xRTT 1xRTT theoretical max speeds are 150kbps/80kbps. • EVDO Rel 0 EVDO Rev 0 provides speeds of 600Kbps-1,400Kbps Download (bursts to 2.4Mbps), 500Kbps-800Kbps Upload (bursts to 1.5Mbps). • EVDO Rel A EVDO Rev A provides speeds of 600Kbps-1,400Kbps Download (bursts to 3.1Mbps), 500Kbps-800Kbps Upload (bursts to 1.8Mbps) - comparable to home DSL service

  17. Need for Carrier provisioning • CDMA technology does not use SIM card for carrier/subscriber provisioning, so this information has to be provisioned on the modem • The carrier specific configuration on the 3G modem are: • Modem ESN and Security Keys • Carrier PRI and PRL • Modem Firmware • Additionally a security information file (flat file) generated during modem provisioning that’s needs to be sent back to the carrier • To support a new CDMA carrier, there are 2 options: • Create additional CDMA HWIC SKU and perform provisioning in manufacturing • Use the generic CDMA HWIC and defer provisioning to Cisco partner/reseller

  18. Now, in practice Actual Bandwidth Values depends on the following Factors • RSSI Value • ECIO Value • Cellular Medium shared among Multiple Users. • Distance between Site to BTS Tower

  19. Antenna • The 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

  20. What is the recommended Values of SNR and ECIO to declare site signal strength bad or fluctuating Or requires DiversityAntenna or Outdoor Antenna

  21. RSSI Recommended Values..-69dBm or better RSSI means good reception and better through. -70 to -89dBm is considered to be ok with reasonable throughput. -89 to -99 dBm is bad reception and throughput will vary significantly. -99 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.

  22. ECIO 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.

  23. CDMA Carrier Generic CDMA HWIC model Sierra Wireless creates a generic CDMA modem Sierra Wireless Sierra Wireless Cisco Manufacturing inserts the generic modem into the generic CDMA HWIC SKU Cisco Manufacturing Generic CDMA HWIC Local Partner/Disti stocks the generic CDMA HWIC and sends them to local vendor Distributor/ Partner Provisioning Partner Local vendor provisions the modem Customer/ Partner Provisioned CDMA HWIC

  24. India CDMA SP • Currently in India we have following THREE Major 3G CDMA Service provider , who offers different variant of activation process . 2

  25. Migration between CDMA Service provider Example: • Provision • With Factory • Reset Package • Provision w/ Reliance or TATA CDMA • By Default BSNL CDMA Modem • Requirements • On site • Required Cable of following •  3G4G-CAB-USB-RSVD(=) is for the “mini-USB to regular USB” RSVD For Fixed 3G • OR • 3G-CAB-RJ45-RSVD(=) is for the “RJ45 to regular USB” RSVD For Module 3G. • WINDOWS XP Laptop • Package tools and Firmware can be downloaded from CCO

  26. Modem Provisioning Process • Sierra Wireless provides a GUI based modem provisioning tool • The 3G HWIC allows direct access to modem via the diag port • Provisioning steps: • Boot up router with 3G HWIC • Enable 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 port • Run 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 carrier PC with Sierra SWFlash Special USB to RJ45 cable HWIC in a Router

  27. Modem Provisioning Tools/Software • SWFlash –Configuration Tool • This is the Windows program that provisions the modem using a package. This program uses the CCT to program/configure modems • Package - Configuration bundle of: • Modem Firmware • PRL – Preferred Roaming List (provided by carrier) • PRI – Product Release Instructions (aka modem NV settings) • Flat File • Output file created by CCT. Contains modem security keys and configuration data that must be sent to the appropriate cellular carrier (copies to Sierra Wireless)

  28. SWFlash Tool - PC System Requirements • Basic requirements • Windows XP Professional (SP 2), WIN7 32 Bit OS computer • Built-in USB or UART connectivity appropriate for modem • 256MB+ memory, 1GB+ hard disk space • Microsoft Excel 97-2003 • Connection to modem on the HWIC • Cisco 3G HWIC product team would provide special USB-to-RJ45 cable • Network connectivity to transfer flat file Note: SWFlash software bundle would be provided by Cisco to the provisioning partner.

  29. Modem Provisioning – Software Tools

  30. Hands on Session • Let us Continue, How to install , Configure and Provision the CDMA Packages.

  31. Main 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 other • RF-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..

  32. 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.

  33. Site Survey Checklist • What 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?

  34. CDMA Activation Methods • Manual Activation • OTAF Activation • OTAF Activation using IVR During OTAF activation process, IVR system expect to receive DTMF digits for various selection process. Using Cisco EEM scripts, we can send the DTMF digits during OTAF process.
