Key Featureses

1. Metal shell design, can withstand harsh working environment

JR254 uses a metal shell design, rich texture and durable, greatly reduced the degree of damage,thus prolonging the service life. Because of the metal material density is much higher than that of plastic, waterproof and dustproof performance has better corrosion resistance and oxidation resistance.

2. High performance chip solutions, large capacity cache

Built-in Qualcomm high-performance chips as well as large capacity 512M flash memory, improve the overall performance of the system can allow more data stored in the cache, thereby enhancing the overall data processing capacity.

3. Support the docking of the third party audit platform to expand value-added services

Third party audit support platform for docking, equipment on the WLAN site daily inspection and found Wifi hot distribution area, combined with the spot management of the online inspection and control platform, formation management information system to form a complete place, meet the Ministry of public security 82 orders, but also can realize the value-added services such as user behavior analysis.

4. Stable and fast network transmission, strong penetration

Based on the IEEE802.11n standard using MIMO technology can provide the maximum transfer rate up to 300Mbps, equivalent to the wireless access rate of the traditional 802.11a/b/g network of more than 6 times. The transmission power of up to 250mW, 3 times higher than ordinary wireless router, and have more penetrating power.

5. Integrated intelligent management

The centralized management mode, equipment through the cloud platform, based on the unified management of the project, the configuration of the batch, batch upgrade maintenance, greatly facilitate the user management and maintenance of equipment. At the same time combined with the cloud platform, you can also experience the rich features, such as roaming, spectrum navigation, user authentication and billing, coupled with high quality the advertising push, portal, WeChat WiFi certification, features analysis of operation flow, enhance the real operation ability of users.

6. Superior performance

● Support automatic channel selection through the wireless controller or the cloud platform of intelligent channel switching function, can guarantee that each AP can be assigned to the optimal channel, as far as possible to reduce and avoid the adjacent channel interference makes the connection more stable performance.

● Support AP intelligent load sharing, through the wireless controller or cloud platform channel intelligent switching function, real-time analysis of the location of a wireless client dynamically determined in the current time and the current position of AP which can share the load, so as to avoid the client while connected to a AP, cause client throughput reduction problem.

● No support for weak signal access, weak signal management functions by forcing the weak signal terminal to go offline, and the AP actively sends the relief frame to a STA that is below the specified signal strength or specifies the access rate, allowing STA to reconnect or roaming. Suitable for high density WLAN network (AP dense arrange, such as gymnasium, lecture hall, library, report hall, dormitory, the conference site, etc.) to ensure access to users, improve the user experience.
