The GSM infrastructure is evolving rapidly to
meet the data communications requirements of mobile professionals. The mobile switching center (MSC) of the network connects to the Public Switch Telephone Network (PSTN), and the modem pool of the GSM network pumps the data over the phone network. This solution is ubiquitous but includes modulation/demodulation at both ends of the communications link. To bypass modulation, all-digital solutions such as the AVM Computersysteme M1 controller use the GSM/ISDN interface. In the near future, Internet service providers partnering with GSM operators will offer direct Internet access at ISDN rates.
The General Packet Radio Service (GPRS) data packet technology, which will be suitable to handle the bursty nature of wireless data traffic, is still two years off. Meanwhile, when GSM phones with PDA-like functionality show up, Short Message Service (SMS) will take off as a platform for communication applications with low data-transfer requirements.

My approach to software engineering is far more pragmatic than it
is
theoretical--and no language better exemplifies this than C++.
