Mobile Network
Cisco Cius SP supports HSPA+ (4G), W-CDMA (3G), and EDGE (2G) networks.
AT&T is the network provider for Cisco Cius SP.
HSPA+ provides an evolution of High Speed Packet Access and can offer data rates up to 84 Mbps to the mobile device and
22 Mbps from the mobile device when MIMO (multiple antennas) are utilized.
In order to achieve higher data rates, a higher modulation or if dual cell technology (combining multiple cells into one) must be
utilized.
The actual speed for a user will be lower than the peak speeds mentioned above. Typically HSPA+ will offer higher connection
speeds only when close to the cell tower.
HSPA+ can have a quicker wakeup time, which results as an always-on connection experience.

HSPA+ should not be confused with LTE.
Signal requirements and coverage are to be guaranteed by the service provider.
Audio or video quality over the service provider’s mobile network can not be guaranteed.
It is recommended to use 360p or lower quality for video calls over the mobile network.
There is no quality of service (QoS) or call admission control (CAC) across the mobile network including VPN sessions.
There is no support for seamless handoff between mobile networks and Wi-Fi / Ethernet.

• An existing call on the wireless LAN will be not be carried over to the mobile network when roaming out of WLAN
coverage unless a VPN session is active. There will be a noticeable audio gap when transitioning from the wireless
LAN to the mobile network as the mobile network connection and VPN connection must be established before RTP
can resume.

can resume.
• An existing call can remain up on the mobile network (VPN required) when roaming into coverage of a configured
wireless LAN.
