Wifi Chuyên Dụng Xirrus XR 4820

he 

Xirrus XR-4820 Wireless Array

 is the first modular Wi-Fi product of its kind featuring upgradability, high scalability, high performance and integrated security to economically serve today’s requirements without sacrificing for tomorrow’s demand.

The XR-4820 Arrays deliver 4x the coverage, up to 8x the bandwidth and user density compared to legacy thin AP solutions. This equates to 75% less equipment, cable runs, and switch ports - resulting in a significant reduction in installation and ongoing management efforts compared to competitive solutions. The Xirrus XR-4820 combines unmatched flexibility in wireless standards with the ability to scale a network to meet increasing capacity demands without adding additional devices.  

At A Glance

• Configurable with 8 multi-state radios (2.4GHz and 5GHz)

• 300Mbps Multi-State (2.4GHz or 5GHz)

• WiFi bandwidth upto  2.4Gbp

• Field upgradable to more radios or new technologies

 

Benefits:

Upgradable

Adapt to changes in business requirements with the ability to upgrade across Xirrus XR-4820 Array. Deliver a solution with a true 5 year life cycle that can incorporate new technologies as they come to market without starting over.

Scalable

Maintain a high level of performance for mission-critical applications and support the ability to handle unpredictable user growth throughout your Wi-Fi network. Scale the number of users by adding radios and scale capacity by increasing the network traffic throughput without installing additional devices.

Secure

Eliminate potential gaps in security infrastructure with the Xirrus XR-4820 integrated firewall, threat sensor and spectrum analyzer providing comprehensive security without the need for additional equipment.
