TTG: Wireless Access Controller

The goal of zero-latency roaming is to allow clients to seamlessly maintain their connection as they move from one access point to another.

Industrial Wireless Access Controller features Controller-based Turbo Roaming technology to enable millisecond-level roaming across different IP subnets.

Maximum Availability
• Device-level redundancy via hot standby controller

Minimum Handover Time
• Millisecond-level Turbo Roaming
• Inter-controller roaming

Maximum Mobility in L3 Networks
• Mobile IP tunneling
• Care-of-Address (CoA) assignment
• Cross Layer 3 subnet roaming
