1 Introduction to the Product

About This ChapterThe OptiX RTN 310 (RTN 310 for short) is an full-outdoor radio transmission product thatoperates at 6 GHz to 42 GHz. The Outdoor Access Unit (OAU) 1A is the full-outdoor accessunit of the RTN 310.

1.1 Equipment Model

The RTN 310 supports the split model.

1.2 Positioning

The RTN 310 is used to provide transmission solutions with low network construction cost for

mobile communication networks and private networks.

1.3 Benefits

The RTN 310 provides a tail access solution that significantly reduces operational expenditure

(OPEX) and capital expenditure (CAPEX) of mobile backhaul networks. The RTN 310 also provides a microwave channel solution for transparent transmission on the IP radio access

network (IP RAN).

1.4 Specifications

The RTN 310's specifications meet the requirements of mobile backhaul and private network backhaul.

1.1 Equipment Model

The RTN 310 supports the split model.

The split RTN 310 consists of the outdoor access unit (OAU 1A) and ODU, which areconnected using an IF cable. See Figure 1-1.

Figure 1-1 Split RTN 310

The OAU 1A performs service access, multiplexing, IF processing, system communication

and control. The ODU converts the frequency and amplifies the power of signals. The RTN310 uses the RTN XMC ODU, covering the entire frequency band from 6 GHz to 42 GHz.

For details about the RTN XMC ODU, see RTN XMC ODU Hardware Description.

The split RTN 310 can use the existing RTN XMC ODUs to implement zero footprintinstallation.

Unless otherwise specified, the RTN 310 mentioned in this document refers to the split RTN 310.

1.2 PositioningThe RTN 310 is used to provide transmission solutions with low network construction cost for

mobile communication networks and private networks.

Compared with the traditional split radio equipment, the RTN 310 supports full-outdooroperating environment and zero footprint installation. Therefore, the RTN 310 can provide

carriers with full-outdoor radio transmission solutions with low network construction cost andoperating expense.

The RTN 310 supports flexible networking. RTN 310s can form ring or chain backhaulnetworks for various IP base stations on existing or new networks.

The RTN 310 supports 2048QAM, XPIC, PLA, and 1+1 HSB/FD/SD. It can providehigh-bandwidth backhaul links for high-capacity 3G/LTE base stations.

The main RTN 310 applications on mobile communication networks are as follows:







3

RTN 310 independently form tree or ring backhaul networks to provide links with highcapacity, bandwidth, and reliability for 3G/LTE base stations. See Figure 1-2.

The RTN 310 works with the ATN to provide a microwave channel solution for

transparent transmission on the IP RAN. See Figure 1-3.

When an existing OptiX RTN 900 IDU needs to be moved outdoors, the RTN 310'sOAU 1A can replace the OptiX RTN 900 IDU. See Figure 1-4.

1.3 BenefitsThe RTN 310 provides a tail access solution that significantly reduces operational expenditure(OPEX) and capital expenditure (CAPEX) of mobile backhaul networks. The RTN 310 also

provides a microwave channel solution for transparent transmission on the IP radio accessnetwork (IP RAN).

Zero Footprint Installation and Quick Service Provisioning

The RTN 310 integrates service processing, baseband processing, and radio frequency (RF) processing functions, which effectively reduces the costs on site construction and deployment.







5

The RTN 310 uses the split design. The RTN 310 can work with the existing XMC ODUto implement zero footprint installation.

The RTN 310 supports DC and power over Ethernet (PoE). PoE does not require power

cables.

Initial configuration data can be imported from a USB flash drive to the RTN 310, whichhelps implement quick site deployment.

When the OAU 1A is installed under a tower, users can commission and maintain theOAU 1A easily. When the OAU 1A is installed on a tower, users can commission and

maintain the OAU 1A through Wi-Fi, without setting up a physical connection to theOAU 1A.

The RTN 310 supports automatic fading margin tests.

Integrated IP radio with High Bandwidth and High Spectrum Utilization

The RTN 310 provides one channel of Integrated IP radio based on native Ethernettransmission mode, featuring high bandwidth and transmission efficiency.

The RTN 310 supports 7 MHz, 14 MHz, 28 MHz, 40 MHz, and 56 MHz channel

spacings for air interfaces.

The RTN 310 supports multiple modulation schemes, including QPSK Strong, QPSK,16QAM Strong, 16QAM, 32QAM, 64QAM, 128QAM, 256QAM, 512QAM, 512QAM

Light, 1024QAM, 1024QAM Light, and 2048QAM. The difference between strong/lightmodulation schemes and normal modulation schemes lies in forward error correction(FEC) encoding parameters. Strong modulation schemes have stronger error correction

capabilities, which result in higher receiver sensitivity but lower air interface bandwidth.Light modulation schemes have poorer error correction capabilities, which result in

lower receiver sensitivity but higher air interface bandwidth.

The RTN 310 supports a maximum of 600 Mbit/s Ethernet service throughput at airinterfaces.

The RTN 310 supports Ethernet frame header compression. The equivalent Ethernetservice throughput at air interfaces can reach 1 Gbit/s.

The RTN 310 supports cross polarization interference cancellation (XPIC), which can

double the service capacity of a microwave channel with the bandwidth unchanged.

The RTN 310 supports adaptive modulation (AM), which improves spectral efficiency.

When channel quality is good (such as on clear days), the RTN 310 uses a high-ordermodulation scheme so that more user services are transmitted. In this manner, thetransmission efficiency and spectrum utilization of the system are improved. Whenchannel quality deteriorates (such as on stormy or foggy days), the RTN 310 uses a

low-order modulation scheme so that only higher-priority services are transmitted using

the available bandwidth and lower-priority services are discarded. In this manner, theanti-interference capability of links is improved, and the availability of higher-priority

services is ensured.

Figure 1-5 shows the step-by-step AM shifts caused by weather changes and their impacton service throughput and reliability. In this example, the modulation scheme ofguaranteed AM capacity is QPSK Strong, and the modulation scheme of full AM

capacity is 256QAM.

Easy Management and Maintenance

The RTN 310 provides a variety of management and maintenance features, which effectivelyreduce maintenance cost.

During parts replacement, data can be backed up and imported using a USB flash drive. Software can be upgraded using a USB flash drive. Services are not interrupted during

the upgrade.

The iManager U2000-T can manage the RTN 310 and other Huawei equipment in a

unified manner.

SNMP Get and Set are used to manage the RTN 310. The SNMP agent can be used to

query alarms and performance events and to configure and query parameters includingservice parameters.

Maintenance personnel can perform routine maintenance on the RTN 310 without the

need to be physically present onsite.

When the OAU 1A is installed under a tower, users can commission and maintain the

OAU 1A easily. When the OAU 1A is installed on a tower, users can connect the MobileLCT or Web LCT to the OAU 1A through Wi-Fi to maintain the OAU 1A.

The RTN 310 supports ETH OAM, which helps manage and monitor Ethernet services

in an end-to-end manner.

1.4 Specifications

The RTN 310's specifications meet the requirements of mobile backhaul and private network backhaul.

The throughput specifications in the preceding tables are based on the following conditions:

Frame header compression disabled: untagged Ethernet frames with a length from 64 bytes to 9600

bytes

L2 frame header compression enabled: untagged Ethernet frames with a length from 64 bytes to9600 bytes

L2+L3 frame header compression (IPv4) enabled: tagged Ethernet frames with a length from 70 bytes to 9600 bytes

L2+L3 frame header compression (IPv6) enabled: tagged Ethernet frames with a length from 90

bytes to 9600 bytes

The difference between strong/light modulation schemes and normal modulation schemes lies in

FEC encoding parameters. Strong modulation schemes have stronger error correction capabilities,which result in higher receiver sensitivity but lower air interface bandwidth. Light modulationschemes have poorer error correction capabilities, which result in lower receiver sensitivity buthigher air interface bandwidth.

5.1.2 Channel ConfigurationThe OptiX RTN 310 supports three channel configuration modes: adjacent channel

co-polarized (ACCP), adjacent channel alternate polarization (ACAP), and co-channel dual polarization (CCDP).

ACCP

ACCP allows signals to be transmitted over the electromagnetic waves in the same

polarization direction on two adjacent channels. See Figure 5-1.
