About This Chapter

The OptiX RTN 360 radio transmission system (RTN 360 for short) is a full-outdoor radio transmission product that operates at the V-band (a frequency band ranging from 59 GHz to 64 GHz).

1.1 Network Application

1 Product Introduction

RTN 360 is tailored for service backhaul for small cell base stations that are deployed on buildings or at the street level. RTN 360 plays an important role in the Huawei radio backhaul solution for small cell base stations.

1.2 Product Specifications

RTN 360's specifications meet the requirements of service backhaul for small cell base stations. In addition, RTN 360 features excellent immunity to interference, and is easy to install and maintain.

1.3 Site Configurations

RTN 360s are usually powered by Docks or other standard power sourcing equipment (PSE). RTN 360s can form sites providing one-direction, two-direction, or multi-direction microwave links.

1.1 Network Application

As V-band full-outdoor radio equipment, RTN 360 has the following characteristics:



RTN 360 operates at the frequency band ranging from 59 GH to 64 GHz. It requires unobstructed line of sight (LOS) and features low inter-site interference and rich idle frequency spectrum resources. A V-band link can span a maximum distance of 300 m, meeting the requirements of service backhaul for small cell base stations. RTN 360 can provide large-capacity microwave links for small cell base stations densely deployed in downtown areas.

1.3 Site Configurations

RTN 360s are usually powered by Docks or other standard power sourcing equipment (PSE). RTN 360s can form sites providing one-direction, two-direction, or multi-direction microwave links.

1.3.1 Sites Providing One-Direction Microwave Links

If a small cell base station is located at the end of a transmission link, an RTN 360 is required to provide a 1+0 unprotected microwave link. The RTN 360 receives power signals and service signals from the Dock of the small cell base station.

Figure 1-2 illustrates configurations of a site providing a one-direction microwave link.

If a small cell base station can serve as standard PSE, RTN 360s can directly receive power signals and service signals from the small cell base station.

1.3.2 Sites Providing Two-Direction Microwave Links

If a small cell base station is an intermediate node on a transmission link, two RTN 360s are required to provide two 1+0 unprotected microwave links in different directions. RTN 360s receive power signals and service signals from the Dock of the small cell base station.

If a macro base station connects to multiple small cell base stations in a star topology, in addition to multiple RTN 360s, an OptiX RTN 900 (IDU) (for example, an IDU 950A) or other power sourcing equipment (PSE) is required. The IDU supplies power to the RTN 360s through a PoE board (for example, an EG4P board) and aggregates services.

data

RTN 360 uses a wide frequency band design, which enables a single chassis to cover the entire V-band from 59 GHz to 64 GHz. This eliminates the need to distinguish TX high and low sites, which means that spare parts need to be prepared for only one equipment model.

Both RTN 360 and Huawei small cell base stations can be installed on walls and poles. They are similar in appearance and look harmonious when installed together.

2.2 TDD

Time division duplex (TDD) has unique advantages over frequency division duplex (FDD) in asymmetric transmission and high frequency spectrum resource utilization.

In FDD mode, symmetric frequencies are required to function as the uplink and downlink channels. The V-band is license-free in most areas and may be used by multiple users, and it is difficult to obtain interference-free symmetric frequencies. Therefore, RTN 360 uses TDD mode.

In TDD mode, asymmetric frequencies are used. Uplink and downlink data is transmitted in different time periods. The ratio of timeslots for uplink data to those for downlink data can be configured based on service requirements, flexibly using frequency resources.

Figure 2-2 Comparison between FDD and TDD modes

Using TDD mode, RTN 360 has the following advantages:



One RTN 360 can cover the operating frequency band (59 GHz to 64 GHz), eliminating the need to distinguish TX high and low sites.



Timeslots for uplink and downlink data can be flexibly adjusted based on actual traffic. The ratio of timeslots for uplink data to those for downlink data can be configured to 3:1, 2:1, 1:1, 1:2, or 1:3.

RTN 360 supports automatic frequency selection, which enables it to automatically select an interference-free channel as the working channel.

RTN 360 scans frequencies within a specified range to select interference-free channels. See

Figure 2-3.

Automatic frequency selection applies to the following two scenarios:



During commissioning in site deployment, this function is used to obtain interference-free channels, releasing engineers from planning microwave link frequencies.



For an in-service RTN 360, this function is used to reselect and switch to an interference-free channel if the current microwave link is interrupted or fails due to interference on the working channel, improving microwave links' immunity to interference.

RTN 360 works with its network management system (NMS) to prevent unauthorized logins and operations, ensuring equipment management security.

Overview of Hardware Security

RTN 360 uses the following hardware security measures:



Microwave ports: The forward error correction (FEC) encoding mode is adopted and the adaptive time-domain equalizer for baseband signals is used. This enables the microwave ports to withstand strong interference. An interceptor cannot restore the content in a data frame if coding details and service configurations are not obtained.



Modular design: Control units are separated from service units, and service units are separated from each other. In this manner, a fault on any unit can be isolated, minimizing the impact of the fault on other units in the system.



CPU flow control: The data flow sent to the CPU for processing is classified and controlled to prevent CPU resources from being exhausted by a large number of packets. This ensures that the CPU operates properly under attacks.



Management port control: The protective cover for the maintenance compartment is kept closed when the management port is not being used, preventing unauthorized access.

Overview of Software Security

RTN 360 processes two types of data: O&M data and service data. The two types of data are transmitted over independent paths and do not affect each other. This enables services running on an RTN 360 to be processed on two planes:



Management plane The management plane provides access to the required equipment and management

functions, such as managing accounts and passwords, communication protocols, and alarm reporting. Security features on the management plane implement secure access, integrated security management, and all-round security audits.



Data plane The data plane processes the service data flow entering the equipment and forwards

service packets according to the forwarding table. Security features on the data plane ensure confidentiality and integration of user data by preventing malicious theft, modification, and removal of user service packets. These features ensure reliable data forwarding by protecting forwarding entries against malicious attacks and falsification.
