An Ethernet cable is shown connecting this port to a wall-mounted Ethernet outlet. The CPE then provides internet access via Wi-Fi or its LAN ports to devices like computers.

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: A network diagram illustrates the VPN client functionality. It shows a PC connected to an 'LTE VPN Client' which then connects to the LTE network. The CPE is part of this LTE network. The connection then goes through a VPN Tunnel to a Serving Gateway (SGW), then a PDN Gateway (PGW), leading to the Internet and finally a VPN Server. This depicts a typical VPN client setup where the CPE facilitates the VPN connection for the PC.

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: This diagram shows the VPN pass-through functionality. It depicts an LTE connection leading to the CPE. From the CPE, a VPN tunnel is established directly to a VPN server, bypassing the need for the CPE itself to act as a VPN client. This allows devices on the LAN side of the CPE to establish their own VPN connections.

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 WAN IP address.

Diagram Description: Two cases are illustrated for IP Pass-Through. Case 1 shows a PC directly connected via Ethernet to the CPE's WAN port, receiving the WAN IP address. Case 2 shows a Router connected via Ethernet to the CPE's WAN port, and then a PC connected to the Router's LAN port. In both cases, the CPE passes the WAN IP address to the connected device (PC or Router).

3.6 IPv6 Only and IPv4v6 Dual Stack

3.6.1 IPv4v6 Dual Stack

CPE provides dual stack function.

Diagram Description: This diagram illustrates the dual-stack (IPv4v6) capability. It shows an LTE connection to the CPE. The CPE then connects to the network via SGW and PGW, facilitating both Internet IPv4 and Internet IPv6 connections. The diagram indicates that both IPv4-only devices and IPv6-only devices can connect to the CPE and access the respective internet protocols.

3.6.2 IPv6 Only (CLAT)

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

When the IPv6 only (CLAT) function is enabled, NAT-based functions (like DMZ/Port Forwarding/Port trigger) 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: This diagram depicts the IPv6 Only mode with CLAT (Customer-side Translator). It shows an LTE connection to the CPE. The CPE connects via SGW and PGW, providing Internet IPv4 and Internet IPv6 access. A key element is the CLAT function which allows IPv4-only devices to access the internet via IPv6. The diagram shows an IPv4-only device connecting to the CPE, which then translates its traffic for IPv6 networks.

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: This diagram illustrates the Multi-APN configuration. It shows a User Equipment (UE) connecting via LTE to the CPE. The CPE then connects to the network via SGW and PGW, providing access to 'Internet IPv4'. Two distinct APN connections are shown originating from the CPE: a 'Default APN' and a 'TR-069 APN', indicating separate pathways for data and management services.

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

3.11 HOTA

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

Diagram Description: This diagram shows the HOTA (Huawei Online Firmware Update) process. It depicts a UE connecting via LTE to the CPE. The CPE then connects through SGW and PGW to the Internet, where it communicates with an Auto-Configuration Server (ACS). This server is responsible for managing and delivering firmware updates to the CPE.

4 System Structure and Scenario Constraints

4.1 System Architecture

Figure 4-1 System structure

This diagram illustrates the system architecture of the HUAWEI B535-232. The central element is the Internet, which connects to the device via 'LTE access function' and 'Ethernet access function'. These functions feed into core processing modules: 'IP route protocol and NAT', 'DHCP/DNS', and 'WEB management'. Additionally, an 'AP function' provides Wi-Fi connectivity, and a 'LAN access function' handles wired connections. End devices like laptops and computers connect to these functions.

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.
