Prerequisites for Configuring the 3G Wireless Interface
The following are prerequisites to configuring the 3G wireless interface:
• You must have wireless service from a carrier, and you must have network coverage where your
router will be physically placed. For a complete list of supported carriers, see the data sheet at:
www.cisco.com/go/m2m
• You must subscribe to a service plan with a wireless service provider and obtain a SIM card (GSM
modem only) from the service provider.
• You must check your LEDs for signal strength, as described in Table 2-1.
• You should be familiar with the Cisco IOS software. See Cisco IOS documentation beginning with
Cisco IOS Release 12.4(15)XZ or later for Cisco 3G Wireless support.
• To configure your GSM data profile, you need the following information from your service provider:
–
Username
–
Password
–
Access point name (APN)
• To configure your CDMA (CDMA only) data profile for manual activation, you need the following
information from your service provider:
–
Master Subsidy Lock (MSL) number
–
Mobile Directory number (MDN)
–
Mobile Station Identifier (MSID)
–
Electronic Serial Number (ESN)
• Check the LED located on the front panel of the router for signal strength and other indications.
Table 2-1 describes the 3G LEDs for the Cisco 819 ISR.
Restrictions for Configuring the Cellular Wireless Interface
The following restrictions apply to configuring the Cisco 3G wireless interface:
• A data connection can be originated only by the 3G wireless interface. Remote dial-in is not
supported.
• Because of the shared nature of wireless communications, the experienced throughput varies
depending on the number of active users or the amount of congestion in a given network.
• Cellular networks have higher latency than wired networks. Latency rates depend on the technology
and carrier. Latency may be higher when there is network congestion.
• VoIP is currently not supported.
• Any restrictions that are part of the terms of service from your carrier also apply to the Cisco 3G
wireless interface.
• Inserting a different type of modem from what was previously removed requires configuration
changes and you must reload the system.
