Feb 20, 2008 — by Eric Brown — from the LinuxDevices Archive — 1 views

Agito Networks announced the availability of its Linux-powered RoamAnywhere Mobility Router. Designed to help enterprises cut mobile phone fees, the router works with dual-mode phones, routing calls over WiFi when available, and passing calls between WiFi and cellular networks.

Announced in October, the RoamAnywhere Mobility Router works together with a client application that can be installed over the air on Windows Mobile or Symbian phones. The product works with any cellular network, the company claims, and users' phones require only a single number, regardless of their location. The router can also route calls over WiFi at home, says Agito, using built-in support for 802.11 a, b, g, and n protocols.

Agito's dual-mode call routing architecture

The RoamAnywhere router comes in two configurations: The 2000 Series router supports up to 100 simultaneous users, says Agito, whereas the 4000 Series router scales up to 1000 simultaneous users. The devices appear to be based on a standard off-the-shelf 1U server platform powered by an Intel Xeon processor of unspecified speed. The 2000 Series version features a single dual-core Xeon processor, while the 4000 Series uses two. A DSP (digital signal processor) co-processor may be implemented as well, as Agito refers to a “hybrid” architecture that separates data flow from control tasks.

The RoamAnywhere I/O features include a 9-pin serial port interface supporting a console connection, a pair of gigabit Ethernet ports, and a USB port. The 4000 model is equipped with 250GB of redundant SATA hard drive storage. Both models run on an in-house version of Linux 2.6.


Pricing for the RoamAnywhere solution starts at approximately $10,000 for the 2000 Series, says Agito, and $28,000 for the 4000 Series.
