whitepaper Its ageing messaging system could not keep pace with the changing communications needs of an increasingly mobile workforce; and a lack of Web mail messaging and wireless email access hindered effective communications and productivity within IRB.
[09 Dec 2007]
whitepaper The solutions target upcoming mobile wireless systems such as IEEE 802.16e wireless MANs (Metropolitan Area Networks) where adaptive modulation is enabled and the underlying medium access scheme is On-Demand Time Division Multiple Access (On...
[05 Dec 2007]
whitepaper The new system supports a high-performance work environment that provides real-time access to multiple communications, enhances message speed and stability, and streamlines access for mobile workers, increasing productivity.
[28 Sep 2007]
whitepaper From multiple locations, employees can now use the Microsoft Office Outlook 2003 messaging and collaboration client, Microsoft Office Outlook Web Access, and a variety of mobile devices to send and receive e-mail messages.
[28 Sep 2007]
whitepaper This white paper presents an overview of General Packet Radio Service (GPRS), a wireless data communications standard that operates over Global System for Mobile Communications (GSM) networks and IS-136 Time Division Multiple Access (TDMA) networks.
[03 Aug 2007]
whitepaper Searching for the proper interface to access multiple resources from a mobile computer the authors have selected an approach based on self-organized hypertext maps. This paper addresses the issue of finding and accessing online educational...
[20 Jul 2007]
whitepaper GPRS (general packet radio service) is a new non-voice service that is being added to existing IS-136 TDMA (time division multiple access) networks in the United States and GSM (Global System for Mobile Communications) networks in the United...
