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


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


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.


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

HWIC in a Router

PC with Sierra SWFlash

Special USB to RJ45 cable


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 FirmwarePRL – Preferred Roaming List (provided by carrier)PRI – Product Release Instructions (aka modem NV settings)

Flat FileOutput file created by CCT. Contains modem security keys and configuration data that must be sent to the appropriate cellular carrier (copies to Sierra Wireless)


SWFlash Tool - PC System Requirements Basic requirements

Windows XP Professional (SP 2), WIN7 32 Bit OS computerBuilt-in USB or UART connectivity appropriate for modem256MB+ memory, 1GB+ hard disk spaceMicrosoft Excel 97-2003

Connection to modem on the HWICCisco 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.


Modem Provisioning – Software Tools


Hands on Session

Let us Continue, How to install , Configure and Provision the CDMA Packages.


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.


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?

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.

Common Field IssuesCommon 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

Troubleshoot Network Attach Issues


Troubleshoot Network Attach Issues (cont’ed)Solution/Steps:

Check antenna connectionmake 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”

No SIM present

Check if a valid SIM is inserted, IMSI verify IMSI number in show cellular <unit> hardware output


Troubleshoot PDP Activation IssuesSymptom:

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

1. 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.

2. 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” outputcontact the carrier to verify account provisioning


Troubleshoot PDP Activation Issues(Cont’ed)

Check if chat-script has been configured properly


Modem Sample chat script

CDMA chat-script cdma "" "ATDT#777" TIMEOUT 30 "CONNECT"

GSM/HSPA chat-script umts "" "atdt*99#" TIMEOUT 180 "CONNECT"

HSPA+ chat-script plus "" "at!scact=1,1" TIMEOUT 60 "OK"

Check if line has been configured correctly.

Troubleshoot Loss of Connectivity IssuesSymptom:

data traffic passes through initially but stops after sometime.

Solution/steps: check PDP session status and IP address

Verify if PDP session is still active and if IP address is available

Check RSSI valueVerify if signal level fluctuates in show cellular <unit> rssi history

Check tx/rx packet countsVerify if packet counts shown in show interface cellular <unit> can be related to byte packets in “show cellular <unit> connection”


Use EEM Script as A Workaround

Event IPSLA object stateMIB objects


Action Clear line or shut/no shut cellular

interface – terminate the data call

Reset or power-cycle the modem

Sample Configuration:ip sla 21 icmp-echo 10.20.40.249 source-interface Vlan2 frequency 360 timeout 6000 ip sla schedule 21 life forever start-time nowaction 560 if $_remainder eq 0action 570 syslog msg "Modem Power Cycle.

Use EEM Script as A Workaround (cont’ed)


Please make sure to suspend EEM script using “event manager scheduler Suspend” when you control the modem from CLI. This is to avoid contention between EEM script and CLI
