Deploying APs over high latency (>100ms) links
After a successful and well received deployment of Ruckus (ZD1100 and 7372s) in our headquarter office, we are considering deploying APs across our worldwide office locations. Ideally management would be through the existing ZD in our US-FL office. Several offices are in the EMEA (Europe) region and one in APAC with average latency of 120-160ms to the EMEA offices and upwards of 200ms to the APAC office. All sites are connected via layer 3 VPN tunnels with sufficient throughput. Each site has local firewall/gateway to the internet (APs will have local internet access).
I've seen several references that <100ms is recommended, but have also seen accounts where successful deployment occurred over much higher latency. Does anyone have experience deploying over high(ish) latency links and what advice would you give in this scenario?
