3 Services and Applications

3.1 Data Services

The B535-232 can access the Internet through mobile networks and Ethernet networks. By connecting to the B535-232 using Wi-Fi or a network cable, users can obtain access to high-speed Internet services and establish a local area network (LAN).

3.1.1 Accessing the Internet through a Mobile Network

The B535-232 can access the Internet through mobile networks.

Figure 3-1 Accessing the Internet through a mobile network: This diagram illustrates the HUAWEI B535-232 LTE CPE connecting to the internet via LTE/UMTS mobile networks. An antenna icon represents the mobile signal. The CPE then provides internet access wirelessly via Wi-Fi (indicated by Wi-Fi signal icons) to devices like a laptop and a smartphone, and via Ethernet cables to devices like a desktop computer.

3.1.2 Accessing the Internet through an Ethernet Network

The B535-232's LAN/WAN port can be connected to a wall-mounted Ethernet port using a network cable.

Figure 3-2 Accessing the Internet through an Ethernet network: This diagram shows the HUAWEI B535-232 LTE CPE connecting to the internet via an Ethernet network. The CPE's LAN/WAN port is depicted connected by a network cable to a wall-mounted Ethernet port, which in turn provides internet access.

3.2 SMS

The B535-232 supports message writing/sending/receiving and group sending (up to 50 contacts at a time).

3.3 Security Service

The B535-232 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.

3.3.1 Firewall Service

The B535-232 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.

3.3.2 MAC Filtering

The B535-232 supports configuration of the Media Access Control (MAC) address to restrict network access.

3.3.3 Wi-Fi Authentication

The gateway supports the following user authentication protocols for Wi-Fi:

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

3.4 VPN Function

3.4.1 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 B535-232 supports L2TP and PPTP tunneling protocols.

Diagram Description: Network diagram illustrating VPN client functionality. A PC connects to the LTE CPE via VPN Tunnel (L2TP/PPTP). The CPE connects to the internet via LTE, then through SGW and PGW to a VPN Server.

3.4.2 VPN Pass-Through

The B535-232 supports L2TP/PPTP VPN pass-through for the LAN side device. The LAN side device can create a VPN tunnel to the VPN server.

Diagram Description: Network diagram showing VPN pass-through. A LAN side device (PC) connects to the LTE CPE. The CPE connects to the internet via LTE, then through SGW and PGW to a VPN Server. The VPN tunnel is established from the LAN device through the CPE to the VPN server.

3.5 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.

Diagram Description: Diagram illustrating IP Pass-Through. Case 1: A PC connects via RJ45 to the LTE CPE, which is connected to the Internet. The CPE passes the WAN IP address directly to the PC. Case 2: A Router connects via RJ45 to the LTE CPE, which is connected to the Internet. The CPE passes the WAN IP address directly to the Router.

3.6 IPv6 Only and IPv4v6 Dual Stack

3.6.1 IPv4v6 Dual Stack

CPE provides dual stack function.

Diagram Description: Diagram showing IPv4v6 dual-stack functionality. An LTE CPE connects to the network. Devices can be IPv4 only, IPv6 only, or dual-stack. The connection to the internet supports both IPv4 and IPv6 through SGW and PGW.

3.6.2 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.

Diagram Description: Diagram illustrating IPv6 only operation with CLAT. An LTE CPE connects to the network. Devices are IPv6 only or IPv4 only. The CPE uses CLAT (Customer-side Translator) to allow IPv4 devices to access the internet via IPv6. The connection to the internet supports IPv4 and IPv6 through SGW and PGW.

3.7 Multi-APN

The B535-232 supports the establishment and maintenance of two APNs. These two APN connections isolate data and remote management services on an operator's network. The B535-232 supports an independent APN for CPE internal/TR-069.

Diagram Description: Diagram illustrating Multi-APN setup. A UE connects to the LTE CPE. The CPE establishes two APN connections: a Default APN and a TR-069 APN, connecting to the internet via SGW and PGW.

3.8 HiLink

• Supports up to 5 HiLink devices to connect to B535-232 through the WPS 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 B535-232 through the WPS button.

3.9 Customer management

3.9.1 WebUI

The B535-232 supports local configuration through the Web UI. You can perform device management and network configuration to ensure normal and stable performance.

3.9.2 HUAWEI SmartHome APP

3.10 Operator maintenance

The B535-232 supports Operator maintenance through the TR-069. Operator remote manages the CPE software update/parameters configuration via TR-069.

3.11 HOTA

The B535-232 supports the HOTA feature, which allows users to remotely update the device firmware through the HOTA server.

Diagram Description: Network diagram showing HOTA (Huawei Firmware Over the Air) functionality. A UE connects to the LTE CPE. The CPE connects to the internet via LTE, then through SGW and PGW to an Auto-Configuration Server (ACS).

4 System Structure and Scenario Constraints

4.1 System Architecture

Figure 4-1 System structure: System architecture diagram for the HUAWEI B535-232 LTE CPE. The diagram shows 'Internet' connecting to the CPE. The CPE has modules for 'Ethernet access function', 'LTE access function', 'IP route protocol and NAT', 'WEB management', 'AP function', and 'LAN access function'. It shows connections to a Laptop and a Computer.

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

• LTE access function: The B535-232 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 B535-232 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/a/ac -compliant Wi-Fi AP interface is provided for wireless networking at home. The interface is compliant with the IEEE 802.11b/g/n/a/ac 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 B535-232 and modify and view the configuration of the B535-232.

IP routing protocol and NAT: The B535-232 has high-speed routing capability. With the built-in NAT, the B535-232, together with LTE terminals, can provide flexible broadband access solutions and networking schemes.

4.2 Scenario Constraints

The B535-232 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 B535-232 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 B535-232 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 64 devices can be connected to the Wi-Fi in theory; the actual number of devices that can be connected and served depends on actual conditions.
