Chapter 1. Product Description of NML-200

1.1Product Summary

NML-200 digital microwave equipment is a new-generation packet microwave

communication system based on an innovative design concept. Rather than using the

traditional structure of split-mount between ODU and IDU, it uses a full outdoor integrated

structure and innovative software/hardware design, integrating RF and Modem into a single,

compact outdoor unit, which is directly connected with the antenna, greatly simplifying the

engineering installation, operation and maintenance.

5/10/20/30/40/60/80MHz ) and flexible modulation schemes (QPSK-1024QAM)

to secure best link performance

• Power supply with coaxial cable and Optional Optical GE port for strong

lightning protection.

• High availability and reliability based on licensed frequency bands from 6.5G to

23G and unlicensed frequency bands at 5.8G, 10.5G 17G and 24G

• Jumbo frame up to 9600 bytes, layer-2 switching, auto MDI/MDXI, VLAN, QoS,

QinQ, STP

• RF and digital loopback capability

• Digital Pre-distortion feature

• ATPC and built-in FEC function

• Small and attractive profile, Low latency and low power consumption, wide

operating temperature range fits all weather conditions

• Local management capability as well as SNMP

• Zero IF design for easy manufacturing.

Chapter 2. Features and Functions of Packet Radio NML-200

2.1 NML-200 Packet Radio Service Type

The NML-200 is pure packet radio, all the service is transmitted by packet frame. To

transmit TDM business, external devices should be used to encapsulate TDM traffic to the IP

packet data frame (Packet). NML-200 provide the flow control, TDM services can be set the

Ethernet Interface Full-duplex or half-duplex optical GE（SFP）

NMS Interface Ethernet RJ45 ( in-band)

2.3 Modulation Mode of NML-200

The NML-200 supports adaptive modulation functions. Adaptive modulation (AM) is a

technology that automatically adjusts the modulation mode according to the channel quality.

The user can decide to enable or disable the adaptive modulation function (AM).

In the case of adaptive modulation function is enabled, the different modulation modes,

the traffic capacity of the microwave is also different, the higher the modulation mode, the

higher the capacity of transmission service. For example, in a good channel quality (such as

Clear), the device uses a high modulation mode, more business can be transmitted, in order to

improve throughput and spectrum utilization efficiency of the spectrum resources. In a bad

channel quality (rain, snow, etc.), the device uses a low modulation mode, then the

transmission quality and reliability is improved, but services throughput dropped, the

transport business choice according to the traffic management mechanisms (QoS), high

priority traffic transmission priority, low-priority traffic is discarded.

The features of the AM function of NML-200 is listed below：

� Support QPSK/16QAM/32QAM/64QAM/128QAM/256QAM/512QAM/1024QAM

modulation mode, user license also decided the highest available modulation mode.


2.4 Traffic capacity of NML-200

The traffic capacity of NML-200 support to 450Mbps, the actual traffic capacity is

determined by channel bandwidth, modulation and the user license.

2.5 ATPC function of NML-200

The NML-200equipment provide automatic transmitter power control function (ATPC). The

output power of the transmitter can automatically adjust by tracking the receiving signal

This function can reduce the interference of the adjacent communication system. ATPC

performance of NML-200 is shown in Table 2-X.

Chapter 3. Installation and commissioning

3.1 Radio installation

There are two options to install the radio with antenna, one is to use 4-clips to fix with

antenna, or to use 4-screws to fix with antenna.


Option1

Fig 3-1 Radio installation using 4 clips

This slip-fit installation uses 4 clips to fix the radio with antenna. The polarization

consistency of the radio and the antenna should be ensured during the installation.

Option2
