Key Features

LINK REDUNDANCY & FIBER ARBITRATION

•  Smart packet arbitration between wireless and fiber back-up to ensure best performance and zero loss of data or service outages 
•  Fiber back-up for wireless connectivity disruption due to inclement weather conditions
• Integration with nxLink – Share
  • Monitors packet time spent in input buffers

Latency: 

• 200 ns User-to-User latency for 64 byte payload

ZERO PACKET LOSS

• Secures an unreliable RF link using a stable backup fiber network
• Duplicates ingress packets and performs deduplication on the receiving device
• Maintains TCP connections over RF links and prevents client disconnects
