whitepaper Design and Simulation of Orthogonal Frequency Division Multiplexing (OFDM) Signaling2001-05-15 Bradley University
  A MATLAB program has been written to investigate Orthogonal Frequency Division Multiplexing (OFDM) communication systems. This program is valuable for future researchers simulating systems that are too theoretically complex to analyze. Single carrier QAM and multicarrier OFDM are compared to demonstrate the strength of OFDM in multipath channels. Two graphical user interface demonstrations show some of the basic concepts of OFDM.   
whitepaper Paradise Datacom Connecting GSM Networks Via Satellite2004-10-01 Paradise Datacom
  The worldwide popularity of GSM has encouraged operators to deploy services in most cities and, increasingly into remote areas. In parts of the world where the terrestrial infrastructure is non-existent, GSM has enabled telecom services for the first time. The only practical way to extend GSM services into these remote locations has been via satellite. Paradise Datacom P300 series satellite modems and BUCs are ideally suited for GSM over satellite systems. Increased bandwidth (space segment) efficiency and better system functionality are the key benefits of using these products for GSM over satellite links.

whitepaper Understanding Upstream Modulation Profiles2003-01-01 Cisco Systems
  Modulation profiles define how information will be transmitted upstream, from a cable modem to the cable modem termination system (CMTS). Many upstream modulation profile variables can be changed, such as guard time of the burst, preamble, modulation (quadrature phase shift keying [QPSK] or 16-quadrature amplitude modulation [QAM]), and forward error correction (FEC) protection. Cisco has created three default profiles, qpsk, 16qam, and mix to eliminate confusion, but changes may be necessary depending on the application.   
whitepaper All You Wanted to Know About T1 But Were Afraid to Ask0000-00-00 Data Comm for Business
  We are experiencing a breakneck growth in the interconnection of personal computers, terminals and telephones in the business environment. T1 technology is proving to be a cost-effective means of linking voice and data, both inter-office and intra-office, and serves as an alternative to high speed modems for data transport. There is significant discussion these days about "T1 Gateways" and "T1 trunks" as the cost from the various phone companies of these services goes down. Users are discovering that it costs less to have a T1 trunk than a series of leased telephone lines in a point-to-point topology. This increase in the use of T1 requires a fundamental understanding of the technology.

whitepaper Cable Modems0000-00-00 International Engineering Consortium
  Cable modems are devices that allow high-speed access to the Internet via a cable television network. While similar in some respects to a traditional analog modem, a cable modem is significantly more powerful, capable of delivering data approximately 500 times faster.

This tutorial explores the high-speed access capability of cable modem technology in detail, with emphasis on mode of operation, network architecture, alternative technologies, and security issues. 		  
whitepaper Build Yourself an ISP0000-00-00 Patton Electronics
  As an ISP you will offer a service which generally includes some kind of access to the Internet. This can be through dial-up modems, DSL, cable, wireless...you name it! There are two ways of becoming an ISP. One is becoming a Virtual ISP which is reselling another ISP’s service under your own name. The other way is becoming a facilities based provider which means you own and operate the physical pieces which make up your network. By becoming a facilities based provider you’ll get some routers and servers, an upstream Internet connection and some phone lines. The number one service a provider offers is dial-up modem access. The center of being an ISP is the Internet and the foremost service is Dial-up modem access, with just a few pieces of equipment you too can build yourself an ISP.

whitepaper The Role of Power Line Communications in the Networked Home0000-00-00 ITRAN Communications
  The role of power line communications in the home network is as an omnipresent device control and high speed networking avenue. Power line device control modems, if robust enough to overcome the strong interference of the medium, offer excellent value through low silicon costs. Power line networking modems, if able to deliver 1.5Mbps bit rates and high robustness, offer significant cost advantages over phone line and RF media, and can be accessed through every power outlet in the home.
