The goal of zero-latency roaming is to allow clients
to seamlessly maintain their connection as they move from one access
point to another. Moxa's WAC-2004A Industrial Wireless Access Controller
features Controller-based Turbo Roaming technology to enable millisecond-level
roaming across different IP subnets. The advanced roaming algorithm
along with Mobile IP technology allows wireless clients to roam between
APs in different IP subnets within milliseconds, while upholding stringent
security in extremely demanding environments. The rugged WAC-2004A
is capable of operating at temperatures of 0 to 50°C and is suitable
for on-site installation in harsh industrial environments.
