While ordinary IEEE 802.11 technology is fine for data, voice calls require a higher degree of consistency and quality as voice data travels in the bit stream.

To that end, Aruba unveiled a technology road map for its voice-aware WLAN "mobility" controllers.

Paul DeBeasi, a senior analyst at The Burton Group, said this is the first time that a WLAN vendor is doing anything in the FMC space.

"The thing that causes me to pause -- this is just a roadmap. I will get excited when they actually deploy FMC and they have customers that say it doesn't drop calls and it works great," said DeBeasi.

All of the technology Aruba laid out in its announcement is standards-based, said Keerte Melkote, a co-founder of Aruba Networks. The company is building a reference client that they will provide as open source and will work on any wireless-based infrastructure, Melkote said.
