Does the diversity antenna support both uplink and downlink?
The diversity antenna supports only downlink; the main antenna supports both uplink and
downlink.

When I use the sh cellular x/x/x radio command, I get the following message under HDR
(1 x EVDO)-related information:
Rx gain control(Main)= -0 dbm, Diversity = Unavailable
Does this message mean that the diversity antenna is disabled? If so, how do I enable
it?
Antenna diversity should be enabled by default. The code base uses the diversity RF path only
when in active traffic. This message indicates that you need to test the antenna while a call is
in progress.

Features and Functions
Is quality of service (QoS) supported with the 3G HWIC wireless cards?
QoS is supported on the router itself; none of the service providers support QoS on their
current wireless networks.

Do I always need to configure dial-on-demand routing (DDR)?
The 3G HWIC WWAN cellular interface is a DDR interface; that is, the connection is set up
only when there is associated traffic. So you have to configure the dialer group and Chat script
whether the cellular interface is being used as a primary or backup.

Can I configure the 3G HWIC WWAN cellular interface as the primary interface and
configure another interface as a backup to the cellular interface?
No. The 3G HWIC interface is an asynchronous serial, DDR interface. You cannot configure
another interface as the backup interface to any DDR interface because the DDR interfaces
themselves are designed to function primarily as backup interfaces.

Account Activation and Provisioning
Is the account information of the Cisco 3G HWIC saved on Cisco IOS Software? If I
remove an existing Cisco 3G HWIC connected to the Sprint network and replace it with
another HWIC, will it retain the same values?
No. The account information for each modem is stored on the modem NVRAM for a Cisco 3G
HWIC CDMA module (3G-HWIC-CDMA) and on the subscriber identity module (SIM) card for
the Cisco 3G HWIC GSM module (3G-HWIC-GSM), not on the Cisco IOS Software.

Each modem on the 3G wireless HWIC is uniquely provisioned using the ESN numbers. You
need to activate the new card with your service provider, and your service provider needs to
move your account information to the new ESN.
