Network Information
===================
Current Service Status = Normal, Service Error = None
Current Service = Packet switched
<snip>
Radio Information
=================
Radio power mode = ON
Current RSSI = -58 dBm
LTE Technology Preference = AUTO
LTE Technology Selected = LTE
Modem Security Information
==========================
<snip>
SIM Status = OK
<snip>
As shown in this output, the RSSI should be better than -9
0 dBm. The SIM status is “OK” and the current service
status is ”Normal”, meaning that the router is ready to make the data call and set up the IP connectivity using the
4G LTE WWAN interface.
5.3 Profile Configuration
Cellular service providers can associate the cellular devices to different pools using the access point names
(APNs). These pools can be maintained in different ways, such as per service type or per enterprise type. Cellular
service providers typically use the APN for enterprises to provide a specific private IP address or static IP address
for the enterprise devices. By default, profile 1 is prepopulated with a default APN that gives a dynamic IP address
to the endpoint, such as the EHWIC. Cellular service providers can provide a managed connectivity using an
enterprise-specific APN. This profile configuration command can be used to modify the default profile to a
specific one:
ROUTER#cellular <unit> lte profile create <profile#> <APN_name>
For more details, refer to the Cisco 4G LTE software installation guide:
5.4 LTE Data-Call Setup
, Cisco IOS Software acts as the host operating system, which operates the cellular modem to
set up the data call on the radio side with the cellular network. After the call is set up, the modem passes the IP
address to the Cisco IOS Software. All subsequent data traffic is passed to Cisco IOS Software by the modem in a
data-packet format.
