Services and Applications

Data Services

The B311-221 can access the Internet through mobile networks and Ethernet networks. By connecting to the B311-221 using Wi-Fi or a network cable, users can obtain access to high-speed Internet services and establish a local area network (LAN).

Accessing the Internet through a Mobile Network

(LTE/UMTS/GSM)

The B311-221 can access the Internet through mobile networks.

Accessing the Internet through an Ethernet Network

The B311-221's LAN/WAN port can be connected to a wall-mounted Ethernet port using a network cable.

Voice Services

The B311-221 provides one telephone port that can be connected to telephones for calling.

SMS

The B311-221 supports message writing/sending/receiving and group sending (up to 50 -contacts at a time).

Security Service

The B311-221 supports comprehensive and robust security services. It provides a firewall function and PIN protection mechanisms. These features allow users to connect their computers to the Internet and simultaneously protect their computers against security threats from the Internet.

Firewall Service

The B311-221 supports the enabling or disabling of a firewall on the network connection, which protects the device and network from attacks by hackers on the Internet and controls access to the Internet.

MAC Filtering

The B311-221 supports configuration of the Media Access Control (MAC) address to restrict network access.

Wi-Fi Authentication

The gateway supports the following user authentication protocols for WLAN:

• No encryption
• WEP, WPA2-PSK (AES), WPA/WPA2-PSK (TKIP/AES).

VPN Function

VPN Client

VPN tunneling involves establishing and maintaining a logical network connection (that may contain intermediate hops). On this connection, packets constructed in a specific VPN protocol format are first encapsulated within some other base or carrier protocol, then transmitted between the VPN client and server, and finally decapsulated on the receiving side.

The B311-221 supports L2TP and PPTP tunneling protocols.

VPN Pass-Through

The B311-221 supports L2TP/PPTP/IPsec VPN pass-through for the LAN side device. The LAN side device can create a VPN tunnel to the VPN server.

IP Pass-Through

The LTE CPE obtains the WAN IP address and passes it through to the PC (Case 1) or Router (Case 2), and then the PC (Case 1) or Router (Case 2) can directly use the WAP IP address.

IPv6 Only and IPv4v6 Dual Stack

IPv4v6 Dual Stack

CPE provides dual stack function.

IPv6 Only (CLAT)

The LTE CPE supports IPv6 only with the transition solution CLAT for IPv4 device.

NOTE

When the IPv6 only (CLAT) function is enabled, NAT-based functions (like DMZ/Port Forwarding/Port tigger) cannot be used.

When an IPv4 device accesses the Internet, the performance is degraded because packets need to be packetized and unpacked. However, IPv6 devices are not affected.

Multi-APN

The B311-221 supports the establishment and maintenance of three APNs. These three APN connections isolate data, voice, and remote management services on an operator's network.

The B311-221 supports an independent APN for CPE internal/VoIP/TR-069.

HiLink

• Supports up to two HiLink devices to connect to B311-221 through the WPS/Hi button to create an expanded network.
• Supports quick connection between a HiLink device (such as Honor set-up boxes and Honor handsets running on EMUI 5.0 and later) and B311-221 through the WPS/Hi button.
  

Customer management

WebUI

The B311-221 supports local configuration through the Web UI. You can perform device management and network configuration to ensure normal and stable performance.

HUAWEI SmartHome APP

Scan the QR code (can be found in the Quick Start Guide and Web UI) to download the HUAWEI SmartHome APP and configure the router from your phone.

Operator maintenance

The B311-221 supports Operator maintenance through the TR-069. Operator remote manages the CPE software update/parameters configuration via TR-069.

HOTA

The B311-221 supports the HOTA feature, which allows users to remotely update the device firmware through the HOTA server.

System Structure and Scenario Constraints

System Architecture

Figure 4-1 System structure

The following describes the modules shown in Figure 4-1.

• LTE access function: The B311-221 adopts the LTE access technology at the WAN side.
• LAN access function: One 10/100/1000 Mbps high-speed Ethernet ports are provided at the LAN side. The B311-221 provides the switching function for local networking and sharing of the broadband network when it is connected to terminal devices.
• AP function: An 802.11b/g/n-compliant WLAN AP interface is provided for wireless networking at home. The interface is compliant with the IEEE 802.11b/g/n standard and the WEP, WPA/WPA2-PSK, WPA2-PSK security authentication mechanisms.
• DHCP/DNS: The DHCP server dynamically allocates IP addresses to PCs.
• Web-based management: You can configure the B311-221 and modify and view the configuration of the B311-221.
• IP routing protocol and NAT: The B311-221 has high-speed routing capability. With the built-in NAT, the B311-221, together with LTE terminals, can provide flexible broadband access solutions and networking schemes.
• Voice function: The B311-221 supports voice services.

Scenario Constraints

The B311-221 is a household wireless broadband access product designed for use in scenarios with relatively few network access devices and relatively low network reliability requirements, such as homes or small office and home offices (SOHOs).

The B311-221 is not an enterprise-grade product. It cannot be used by medium- or large-sized enterprises or in scenarios with high network reliability requirements, such as banks, securities agencies, traffic control, and communications device backhaul.

The B311-221 has the following constraints:

• When the IP Pass-Through mode is enabled, the HOTA function cannot be used.
• When the L2TP/PPTP VPN client function is enabled, the throughput performance will slow down.
• A maximum of 32 devices can be connected to the WLAN in theory; the actual number of devices that can be connected and served depends on actual conditions.
