The ICG NxtMail Server provides a local Wireless Access Point (WAP ) in the aircraft cabin permitting WiFi capable personal devices to access conventional Internet Protocol (IP) based terrestrial services for the purpose of sending and receiving E-Mails and mobile web browsing. The NxtMail Server provides global connections via a single inexpensive Iridium channel. Besides acting as a WAP and Dynamic Host Configuration Protocol (DHCP) Server, the NxtMail Server efficiently and automatically manages link access to optimize “on-air” time and associated costs. The Server has various interfaces that include: multiple serial ports, fax dialup data interface, Ethernet, and USB. The NxtMail Server provides internal router functions and a HTTP server to permit access of up to 10 user devices, offering a truly wireless system for the aircraft cabin. Multiple serial interfaces with port management, permit connections of several RS-232 devices without the risk of port contention, collisions or data corruption. WiFi capable user devices, such as BlackBerry® smartphones and iPhone™ mobile digital devices, are automatically assigned an IP address by the DHCP server to provide immediate access to the system without user intervention or set-up beyond what is required with any WiFi network.
