Core Features and Business Advantages

1. Reliability and link protection

It has multiple protection architectures: non standby, hot backup, spatial diversity, frequency diversity, and quad diversity (spatial+frequency diversity), achieving high link availability for harsh transmission paths such as ultra long and cross water areas. It can be paired with smaller antennas to achieve longer transmission distances.

Forward error correction FEC, high system gain, high dispersion fading margin DFM, industry-leading ability to resist multipath fading.

High neighbor channel interference suppression capability, suitable for use in spectrum crowded frequency bands.

The whole machine comes with a 2-year warranty.

2. Frequency band capability: licensed frequency band+unlicensed frequency band

Licensed frequency bands: covering FCC Part 101/74 and NTIA government regulated frequency bands in North America, including rich frequency bands such as 1.7GHz, 1.9GHz, and 2-11GHz.

License free frequency band: 2.4GHz, 5.8GHz ISM frequency band; Adopting narrowband single carrier modulation, different from spread spectrum unlicensed microwaves, it has higher transmission power, stronger anti-interference ability, and better spectrum utilization.

5.8GHz single channel maximum 150Mb/s; 2.4GHz license free mode up to 16 x DS1 or 24Mb/s Ethernet.

5.8GHz devices can be upgraded to 6GHz licensed frequency band devices through simple hardware replacement, protecting existing investments; 5.8GHz can also be used as an overlay layer for existing 6GHz links to add Ethernet services.

MDR-8000 Lite: Lightweight license free version, no hot backup, capacity of 8 × DS1, transmission power+25dBm, suitable for low capacity links and backup links.

3. Cost reduction related designs

Industry's highest system gain: System gain=transmit output power - receive threshold. Three major benefits: using smaller antennas, reducing tower load and tower leasing costs; Reduce the number of relay stations and extend the single hop distance; Improve link availability.

Unified public platform: a large number of modules with different frequency bands and capacities can be used interchangeably, reducing the types of spare parts and lowering the cost of operation and maintenance training.

Online Capacity Keys Expansion ™： Under the hot backup architecture, changing the key can expand the capacity without interrupting the business, and there is no need to replace the hardware.

Low power consumption: The power consumption is about 1/3 lower than competitors, reducing the configuration of DC power supply, battery, and air conditioning, and lowering equipment procurement and monthly cooling expenses; Mainly relying on passive heat dissipation, most configurations do not require fans.

Compact volume

Standard hot backup rack: 7RU; a single 19 inch rack can deploy up to 4 sets of hot backup devices, with a total capacity of 12 × DS3.

Compact (unprotected): Only 4RU; supports indoor installation, can also be deployed outdoors on poles/walls, without the need for tower mounted electronic units, reducing high-altitude maintenance.

4. Modulation and anti-interference technology

Modulation methods: 32-TCM, 128-TCM, 64-QAM, can be selected as needed: 128TCM maximizes spectral efficiency; 32TCM achieves higher system gain and longer transmission distance.

All digital receiving filtering, excellent adjacent channel suppression; Support ATPC automatic transmission power control: dynamically adjust the transmission power by dB based on the remote received signal level, only increase the power when fading occurs, in compliance with FCC power control, and reduce interference to other devices on the same frequency.

5. Wayside DS1 bypass DS1 business

For every DS3 configured, a bypass DS1 with hot backup protection is provided; 3 x DS3/OC-3 provides 3 bypass DS1s. Can be used for service lines, data channels LAN/WAN， It does not occupy the main business bandwidth and can carry critical business.

6. Network management

The hardware provides 3 64kb/s business channels and 1 16kb/s monitoring channel; The business channel can transmit service voice RS232、 Alarm monitoring data.

USI User System Interface: Windows PC graphical local management, real-time monitoring of alarms, performance, device configuration, recording of received signal level RSL, and analysis of link propagation anomalies.

Supports multiple network management protocols: MCS-11, E2A/TBOS, and SNMP v1/v2/v3 (optional TMN interface module).

ELMC Extended Link Monitoring Channel: Independent of the network management interface, supports remote viewing of alarms, status, remote configuration, and software downloads of connected devices across the entire network.

7. Multi device configuration form

No backup, hot backup, supports linear and ring network topologies; Can superimpose spatial diversity and frequency diversity; The four diversity single rack can accommodate four receivers, which are used for high difficulty links such as ultra long distance and water surface transmission.

Multi channel configuration: Each working channel has independent 100% device protection, which is different from traditional multi line systems that share protection channels. It does not require separate frequency protection, simplifies spectrum coordination, and improves the reliability of high-density links such as multi OC-3.

Main application scenarios

Cellular operator wireless backhaul: base station backhaul, replacing renting DS1 dedicated line; The licensed/non licensed version quickly opens new sites with excellent investment return cycle.

Public safety and local government: inter agency communication, LMR land mobile radio backhaul; Carrying video and IP LAN services; The license free model is used for emergency communication link backup to meet high security redundancy requirements.

Transportation, power, and pipeline industries: covering remote and rugged terrain; Carrying SCADA monitoring, pipeline/highway video surveillance, and enhancing the resilience of homeland security related businesses.

Local exchange operator LEC: Extend the network beyond the franchise area to avoid renting lines from competitors; Used in areas where fiber optic is depleted and wired resources are missing.

Radio and television broadcasting auxiliary services: meet FCC Part 74 standards, achieve studio transmitter link STL, cross regional video distribution, and ensure high-quality video transmission.

Federal government agencies in the United States operate on NTIA regulated frequency bands to avoid land acquisition and construction delays for cable construction, serving agencies such as the Department of Defense, Department of Justice, and Department of the Interior.

Enterprise Private Network: Voice and data interconnection for education, healthcare, banking, large enterprises, industrial parks, metropolitan areas, and cross regional branches, budget friendly.
