Wanlan ad-hoc network radio 70 km test
Test time: 2023-03-31
Tester: project customers and Wanlan technical support personnel
Test Objectives
Through the test, understand the function and completion of the product, verify the consistency of the actual performance of the main parameters such as point-to-point bandwidth, cold start time, and access time after start-up with the product manual, and further communicate the product details and follow-up cooperation methods.
Test points
SITE A IS LOCATED AT AN ALTITUDE OF ABOUT 1 KM ON THE TOP OF MIAOFENG MOUNTAIN, AND SITE B IS LOCATED AT AN ALTITUDE OF ABOUT -50 M ABOVE SEA LEVEL ON TANGZHI MOUNTAIN NEXT TO SHIZHONGWU VILLAGE, AND THE DISTANCE BETWEEN THE TWO PLACES IS ABOUT 70KM, AND THERE IS OCCASIONAL BASE STATION COMMUNICATION INTERFERENCE, the middle shrubs, the mountains are slightly shaded.

Location A

Location B
The equipment at the top of Miaofeng Mountain is AnyMesh-SDR-A2-2*2W car knapsack ad hoc network radio, which we call Radio A, which is placed on the flat ground on the top of the mountain, supported by a triangular bracket about 3 meters high, connected to a hand microphone to realize voice intercom, and a local computer is connected to the radio station to receive remote packetsdata
On the roadside platform of Tangzhishan Reservoir next to Shizhongwu Village (about 1 meter high), AnyMesh-SDR-A2-2*2W car knapsack ad hoc network radio station is also placed, which we call radio station B, which is connected to a hand microphone to realize voice intercom, and the local computer is connected to the radio station to receive remote filling packetsData.
Test equipment
Ad hoc network vehicle piggyback station
Product name | ANYMESH-SDR-A2 (4W) AD HOC NETWORK VEHICLE PIGGYBACK STATION |
Category | Ad Hoc Network Vehicle Piggyback Station (Base Station) |
Product model | ANYMESH-SDR-A2(4W) |
Product Introduction | The ANYMESH-SDR-A2 is a base station-type ad hoc network device that can be carried behind you to reduce extra weight or be fixed as a relay base station. The chain can be automatically built and networked after powering on the computer, and no additional configuration work is required. Each piggyback base station node does not need to forward data information through the central node, and all nodes can be used as data information collection node, relay forwarding node and data information output node at the same time. The networking mode dynamically changes with the environment to meet the requirements of multi-scenario applications. The transmission distance of the equipment can reach more than 50KM in an unobstructed environment, and it is effectively used in various severe environmental fields |

The vehicle-mounted ad hoc network radio adopts the radio technology of Wanlan Communication's new generation of multi-hop ad hoc network protocol, which has the ability to resist complex channel environments and realize the centerless same-frequency ad hoc network broadband service transmission between individual soldiers, vehicles, UAVs and other maneuvering points and fixed points in complex scenarios.
The device itself has a built-in large-capacity lithium battery, compact design, and a single-channel 2*2W and dual-channel 4W transmission power, which can meet the user's rapid establishment of a private network in emergency scenarios and provide a stable transmission channel for the user's voice, message, video and other IP data services.
The product has the characteristics of software defined radio, which is very suitable for military and firefighting fields, and is also suitable for moving vehicles and ship equipment, so as to realize uninterrupted communication between vehicles and vehicles.
It is widely used in smart cities, individual soldiers, public security and armed police, fire rescue, emergency fleet communications, civil air defense border defense, marine unmanned ships, special robots and other fields.

AD HOC NETWORK PULL-DISTANCE NETWORKING TEST (70KM TEST).
2023.3.31 Arrived at the two places at 11:00 to debug the equipment, and after trying to clean the noise and signal strength of the channel 13 80, the test began, and the distance between the two places was about 70KM, Radio A and Radio B are successfully organized and the link is in good condition

70 km 10MHz, 4W point-to-point bandwidth speed measurement
Sender:

At 10MHz bandwidth, the peak value of packet filling is 9.36Mbit/s, and the average rate is 6.19Mbit/s
Receiver:

Under 10 MHz bandwidth, the peak packet filling rate is 9.40 Mbit/s, and the average rate is 6.11 Mbps
Test conclusion: Using our 10MHz, 2*2W ad hoc network radio in 70KM cross-urban area point-to-point packet filling speed measurement of more than 6M, the communication link is very stable.
The channel bandwidth of the stations on both sides is 10 MHz, and the transmission rate is recorded as follows:
Points | Average rate | Highest rate | Audio and video stability |
Radio A | 6.11Mbps | 9.40Mbps | Very stable |
Radio B | 6.19Mbps | 9.36Mbps | Very stable |
