2 Introduction to the ePico3801
2.5.3 Typical Application Scenarios
The ePico3801 is designed to solve the indoor coverage problem of the UMTS network. With
the ePico3801, mobile operators can deploy ordinary indoor coverage, intensive coverage in
office buildings, and hot-spot indoor coverage quickly at low cost.

2.5.1 Access Networking Scenarios

The ePico3801 is connected to an enterprise LAN or modem, which connects the ePico3801 to
the public IP network. Then, the public IP network connects the ePico3801 to the AG, and the
AG connects the ePico3801 to the UMTS core network. Through convergence and UMTS traffic
and signaling forwarding performed by the AG, routing towards the UMTS core network is
achieved. The ePico3801 can be connected to the public IP network in LAN access mode or
modem access mode.
Modem Access
The ePico3801 can be connected the public IP network through a fixed phone modem or cable
TV cable.
Principle of Modem Access
Each ePico3801 is connected to the public IP network through a modem. The digital subscriber
line access multiplexer (DSLAM) performs data convergence and distribution and isolates the
ePico3801 from other ePico3801s through a private VLAN. The service data is sent to the
broadband access server (BRAS) in Point-to-Point Protocol over Ethernet (PPPoE) or Dynamic
Host Configuration Protocol (DHCP) mode, and the BRAS performs access authentication and
billing for the public IP network. After the authentication is successful, the service data is sent
to the SeGW on the core network of the uBro solution through the public IP network. The SeGW
processes the data and forwards it to the AG and AAA.
