This article offers slightly more detail on Meru's support for voice over WLAN: Meru says its suped-up QoS method can support 100 voice users per AP.
I'd like to know what Meru offers for security. If it used VPN, it would have to require a VPN client on the handset, which is a bit of a deal breaker. Standard security like 802.1X doesn't happen fast enough to support quick handoffs for voice. So what is it doing to secure the network?
In other voice over WLAN news, a company in Japan is coming out with a Wi-Fi handset: IPTalk plans to start offering the service next year in Japan.
