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

 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

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

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.
Presentation_ID

21
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.

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

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)
Presentation_ID

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.

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..

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.

DDR Configuration refresher
Cellular is an Async dialer interface similar to an analog modem
Implementation: Routing
Interface Cellular
Encapsulation: PPP
Media Type:
Async
DDR Configuration Steps:
1. Enable DDR on the interface
2. Define chat-script for the dialer
interface
3. Define Interesting traffic
4. Create dialer list for interesting
traffic
5. Map dialer list to the dialer interface

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

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”
