Product Description

2.1 Integration

RTN 360 integrates a built-in antenna and uses a wide frequency band design, which allows a single chassis to cover the entire V-band.

Built-in Antenna

RTN 360 integrates its system control unit, clock unit, power unit, baseband unit, RF unit, and antenna into a single chassis. See Figure 2-1.

Figure 2-1 Integrated chassis with a built-in antenna

Baseband

board Panel antenna

Such a highly integrated design facilitates quick and flexible installation of RTN 360s in fulloutdoor scenarios.

Wide Frequency Band

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.

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 5:1, 4:1, 3:1, 2:1, 1:1, 1:2, 1:3, 1:4, or 1:5.

2.3Automatic Frequency Selection

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 interferencefree channels, releasing engineers from planning microwave link frequencies.

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

2.4 Adaptive Modulation

Adaptive modulation (AM) technology automatically adjusts the modulation scheme based on channel quality.

Modulation Scheme and Air-interface Capacity

When AM technology is enabled and the same channel spacing is used, the available radio service bandwidth varies according to the modulation scheme: the higher the modulation efficiency, the higher the bandwidth of the transmitted services.

•When channel conditions are favorable (such as on sunny days), the equipment uses a higher-order modulation scheme to transmit more user services. This improves transmission efficiency and spectrum utilization of the system.

•When channel conditions are unfavorable (such as on stormy or foggy days), the equipment uses a lower-order modulation scheme to ensure that higher-priority services are transmitted first. If some lower-priority queues become congested due to a lack of available bandwidth, some or all interfaces in these queues are discarded. This method improves the anti-interference capabilities of a microwave link and ensures link availability for high-priority services.

OptiX RTN 360 Radio Transmission System	2 Functions and Features
Product Description

Modulation Scheme Shift and Service Priorities

For Ethernet services transmitted through IP microwave, priorities can be set based on the service bandwidth and QoS policies corresponding to the current modulation scheme, to control service transmission. The transmission of services with the highest priority is ensured.

With the QoS technology, ethernet services are scheduled to queues with different priorities. The services in different queues are transmitted to the microwave port after running the queue scheduling algorithm. When modulation scheme switching occurs, certain queues may be congested due to insufficient capacity at the air interface. As a result, certain services or all the services in these queues are discarded.

Adaptive Modulation

Figure 2-4 shows how the modulation scheme shifts step by step according to weather changes and how modulation schemes affect service throughput and reliability. In this example, the modulation scheme of guaranteed AM capacity is QPSK and the modulation scheme of full AM capacity is 32QAM.

Product Description

Characteristics

The AM technology used by RTN 360 has the following characteristics:

•Supports the QPSK, 16QAM, and 32QAM modulation schemes.

•Can configure both the lowest-order modulation scheme (also called reference scheme or modulation scheme of guaranteed AM capacity) and the highest-order modulation scheme (also called nominal scheme or modulation scheme of full AM capacity).

•Can switch modulation schemes without changing the transmit frequency, receive frequency, or channel spacing.

•Switches modulation schemes step-by-step.

•Features hitless switching. When the modulation scheme is downshifted, high-priority services are not affected while low-priority services are discarded. Switching is successful even when 100 dB/s channel fast fading occurs.

2.5Power over Ethernet

The RTN 360 provides a P&E port through which the RTN 360 supports power over Ethernet (PoE) as a powered device (PD).

In PoE mode, an outdoor network cable carries Ethernet service signals along with DC power signals. PoE has the following advantages:

•Reduces the number of power cables and simplifies installation.

An RTN 360 can work with a power injector (PI) to implement power over Ethernet through its P&E port. See Figure 2-5.

2.10 Rapid Deployment

A variety of technologies are used to simplify RTN 360 installation so that wireless installation personnel can deploy an RTN 360 within 30 minutes.

So that it can be deployed rapidly, RTN 360:

•Uses TDD mode, in which signals are transmitted and received over the same frequency, eliminating the need to distinguish TX high and low sites and requiring spare parts for only one equipment model.

•Supports automatic frequency selection, simplifying microwave link frequency planning.

•Integrates panel antennas, simplifying installation.

•Uses an alignment scope to facilitate antenna alignment, improving installation efficiency.

Figure 2-9 Aligning antennas using an alignment scope

•Supports power over Ethernet. RTN 360 can work with power injector (PI), or other power sourcing equipment (PSE) to receive service signals and power signals, facilitating deployment.

•Supports configuration-free commissioning using a USB flash drive.

•Manages NEs on a per-NE basis using a Wi-Fi module.
