As a service field of social public activities, wireless network coverage is becoming more and more important.

Abosin, a weak current engineering construction company, believes that for most parks, it has the characteristics of large floor area, high user mobility and low wireless data concurrency rate.

If the wireless local area network (WLAN) is deployed in the traditional way, there are also some problems, such as troublesome wiring and high engineering cost. Therefore, it tends to use the wireless data transmission mode at a long distance, so as to save the trouble of wiring, reduce the construction cost and make the deployment of wireless AP more convenient.

requirement analysis
1. Meet the needs of wireless long-distance data transmission and ensure high signal strength
2. Wireless AP devices are relatively scattered and need to meet the needs of simultaneous access of multiple wireless APS in a large range
3. The equipment shall be able to adapt to the harsh outdoor use environment and reach a certain level of lightning protection, waterproof and dustproof
4. The wireless equipment shall support Poe power supply to facilitate access to power supply in outdoor environment and meet the demand of flexible power distribution

5. The wireless equipment shall support unified management and configuration, and monitor the working status of each equipment in real time to make operation and maintenance simple

conceptual design

Wireless network coverage solutions for scenic spots and parks

Characteristics of the plan

The scheme adopts the combination of outdoor wireless CPE and outdoor wireless AP to realize the wireless coverage of the park, and adopts centralized management software to uniformly manage and deploy all CPEs. It has the following characteristics:

High availability

300m wireless transmission rate, built-in outdoor high gain dual polarization antenna, external high-performance independent power amplifier circuit (PA) and low-noise power amplifier receiving circuit (LNA), providing 27dBm (500MW) transmission power and - 95dbm reception sensitivity, especially suitable for outdoor long-distance WLAN applications.

High adaptability

CPE and outdoor AP adopt professional outdoor enclosure design, provide IP55 dust-proof and waterproof, support 15kV ESD electrostatic protection and 4KV lightning protection, and adapt to various harsh environments.

Long transmission distance
The wireless transmission distance is greater than 5km; It works in the pure 5GHz frequency band with small interference and wireless transmission distance of more than 15km.

high reliability

CPE can solve the hidden node problem in IEEE 802.11 protocol, reduce the resource waste caused by client competition mechanism, provide lower delay, higher throughput, greater network capacity and stability, and improve the performance of multi node wireless networks.

Easy to deploy

Poe network cable is adopted for CPE and outdoor AP power supply, and 60m power transmission is adopted to facilitate access to power supply in outdoor environment and flexible distribution.

Rich functions

The web management system provides rich software functions, provides working modes such as AP, AP client, bridge, repeater, AP client router and AP Router, and supports spectrum analysis and linear adjustment of transmission power function. It can focus on system resource status, wireless signal quality, RF status, throughput, wireless client and other system working parameters, and control the working status of the equipment in real time.

Manageability

Unified ac management by wireless controller, automatic discovery and unified management of AP, real-time view of AP operation status, convenient network management and operation and maintenance; CPE equipment can be managed uniformly through centralized management software to reduce the management and maintenance workload during large-scale deployment.
