5 System Structure
Figure 5-1shows the system architecture.
HUAWEI B890 Wireless Gateway V100R001
Figure 5-1 System architecture
The following describes modules shown in Figure 5-1.
LTE access: The B890 adopts the LTE access technology at the WAN side. The
B890 can access the 4G/3G broadband packet-based network through the
point-to-point protocol (PPP) dial-up.
WLAN AP function: An 802.11 b/g/n-compliant WLAN AP interface is provided,
used for wireless networking at home. The interface is compliant with the
IEEE802.11 b/g/n standard and the W PA -PSK /WPA2-PSK/WEP security
authentication.
DHCP/DNS: The DHCP server dynamically allocates IP addresses to PCs. The
DNS parses domain names.
Web management: You can configure, modify and query the configuration
information of the B890.
Routing and NAT: High-speed routing capability. With the built-in NAT, the B890,
together with 4G/3G terminals, can provide flexible broadband access solutions
and networking schemes.
