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 Diversity Antenna or Outdoor Antenna

21. RSSI 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.

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.

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
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
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.

55. Check for Signal/Service Availability
Check RSSI :
show cellular x/x/x radio <history>
For a reliable connection RSSI should be > -90dBm. An RSSI value of -125dBm means no signal.
The history option can be used to monitor network status over a period of time.
Viewing the network and service status:
show cellular 0/0/0 network
If RSSI for WCDMA is less than -100dBm, modem automatically falls back to EDGE.

59. Common Field Issues Common field issues include:
network attach failure
PDP activation failure
Loss of connectivity
Modem initialization sequence:
modem initiates a network scan
modem attaches to a network automatically once a network is found
user can establish a Data Session (activate PDP context) after the attach procedure completes

61. Troubleshoot Network Attach Issues (cont’ed)
Solution/Steps:
Check antenna connection
make sure antenna is firmly attached
Check network coverage
check RSSI value in show cellular <unit> radio [history …]
adjust antenna location if necessary
Check modem is in online state
modem must be in “Online” mode in order to attach to the network. The radio is turned off and not transmitting if it is in “Low Power Mode”

63. Troubleshoot PDP Activation Issues
Symptom:
cellular service has been acquired, but ping fails.
Solution/steps:
Check if GSM or data profile is configured properly
verify APN, username, and password settings in show cellular <unit> profiles
Note that
Username and password have to configured in GSM profile on HSPA-U and HSPA+7 EHWICs and fixed platform SKUs using “cellular <unit> gsm profile create” command.
Username and password are limited to 32 characters in pre-15.1(4)M4 releases.
Check if there is any subscription issue
check “Service Error” in “show cellular <unit> network” output
contact the carrier to verify account provisioning
