eRelay is a wireless transport networking solution, used on the higher band of TDD spectrum (<6GHz). As a network element (NE) in the eRelay system, eRelay remote node(RRN) works together with eRelay BS to perform wireless backhaul.

1.1 Positioning

With the expansion of mobile broadband users (MBB), network capacity is insufficient in some outdoor hot spot areas, affecting user experience. Operators use compact devices such as AP, Micro, and Pico eNodeBs to cover hot spots. In the preceding scenarios, if access devices for fixed networks, such as optical fibers, are used for backhaul, deployment costs are high and fixed network resources are difficult to obtain. Therefore, wireless backhaul is required to solve the problem.

1 Product Positioning

As a wireless backhaul solution, eRelay adopts TDD technologies and provides high throughput with short delay. Compared with backhaul in fixed networks, deployment costs for eRelay are low and frequency resources are accessible. Compared with micro waves, eRelay has advantages in transmission in non line of sight (NLOS) scenarios.

In the eRelay solution, the eRelay RRN provides wireless backhaul channels for

Served Equipments such as Macro, Micro, Pico, video surveillance, AP and fixed

network equipment. RRN access eRelay BS through air interfaces. RRN3301 is one of the Huawei eRelay module. Figure 1-1 shows an eRelay RRN3301.



A single eRelay RRN3301 can be connected to a maximum of two Served Equipments.



A single eRelay RRN3301 supports the maximum uplink and downlink rate of 28

Mbit/s and 80Mbit/s, respectively.

Optimized Transmission Mode with Low Costs



eRelay RRN3301 support layer 2 switching.

Flexible Installation for Fast Network Deployment with Low CAPEX



The eRelay RRN3301 has a highly integrated structure with a small size and light weight, facilitating installation and maintenance and reducing the capital expenditure (CAPEX).



eRelay RRN3301 can be mounted onto a pole, and equipment rooms are not required. eRelay RRN3301 can be flexibly installed on different places and

The eRelay RRN3301 will be managed as a board of BS by operation and maintenance system.

4.2 OM Structure

4 OM

Figure 4-1 shows the operation and maintenance system of the eRelay RRN3301.

Figure 4-1 OM system of the eRelay RRN3301

The OM system consists of the LMT and the M2000. The LMT is used to maintain a single eRelay RRN3301.



To maintain the eRelay RRN3301 remotely, connect the LMT to the eRelay RRN3301 through the Internet Protocol (IP) network.

The M2000, a mobile element management system provided by Huawei, is used to remotely maintain multiple eRelay RRN3301s of different types or software versions.

The OM system provides the following functions:



The LMT performs functions such as data configuration, alarm monitoring, commissioning, and software upgrade.
