LONG DISTANCE MW LINK
1. TITLE
Long Distance Microwave (MW) Link Diagram
2. OVERVIEW
A long distance MW link is a point-to-point wireless communication system used to connect two far locations using microwave radio signals. It is commonly used in telecom networks, ISP backhaul, enterprise connectivity, and remote site communication.
3. MAIN PURPOSE
– Connect Site A to Site B over a long distance
– Carry voice, data, and internet traffic
– Provide backhaul transmission between two network points
– Replace or reduce fiber dependency in difficult terrain
4. DIAGRAM DESCRIPTION
The diagram shows:
– Two telecom towers
– One microwave antenna on each tower
– A wireless microwave path between both sites
– Approximate distance: 50 km
– Indoor/outdoor microwave equipment connected to network devices
– LAN/network distribution at both ends
5. SITE A COMPONENTS
– Telecom tower
– Microwave antenna
– MW radio equipment
– Microwave equipment cabinet
– Router
– LAN connection
6. SITE B COMPONENTS
– Telecom tower
– Microwave antenna
– MW radio equipment
– Microwave equipment cabinet
– Switch
– LAN connection
7. SIGNAL FLOW
LAN/Router at Site A
→ Microwave Equipment
→ MW Radio
→ Antenna
→ Long Distance Microwave Signal Through Air
→ Antenna at Site B
→ MW Radio
→ Microwave Equipment
→ Switch/LAN at Site B
8. KEY COMPONENTS EXPLANATION
A. Tower
– Supports the antenna at required height
– Helps maintain line of sight between both sites
B. Microwave Antenna
– Usually dish antenna
– Focuses and transmits RF signal in one direction
– Receives signal from the remote end
C. MW Radio
– Converts digital traffic into microwave RF signal
– Sends and receives the signal through the antenna
D. Microwave Equipment / IDU-ODU System
– Handles modulation, traffic processing, and radio control
– Connects transmission system with IP network
E. Router / Switch
– Distributes network traffic
– Connects microwave link with LAN or backbone network
F. LAN
– Local user network or downstream devices connected at site
9. LINK DISTANCE
– Shown distance in the diagram: approximately 50 km
– This is considered a long distance microwave link
– Actual achievable distance depends on:
– Frequency band
– Antenna size
– Output power
– Terrain condition
– Fade margin
– Weather effects
– Line of sight clearance
10. BASIC WORKING PRINCIPLE
– Site A sends data through router or network device
– Data enters microwave equipment
– Microwave radio converts it to RF signal
– Antenna transmits signal across open air path
– Remote antenna receives signal at Site B
– Site B radio converts it back to usable network traffic
– Data is then delivered to switch, router, or LAN
11. IMPORTANT DESIGN REQUIREMENTS
– Clear
