Internet Service Provider Options and Pointers |
Chapter FourInternet Service Provider Options and PointersEveryone seems to be talking about the Internet these days. Every television commercial points you to a Web site with more information. At this stage of the game, you should be considering how you want to connect to the Internet. Most users subscribe to an Internet service provider (ISP) for their dial-in access. An ISP serves to link you to the Internet when you need access, saving you from paying for a 24-hour connection. In this lesson, you can find answers to the following questions:
I'll try to answer these questions and more as you go in search of an Internet service provider. Types of ConnectionsThis section explains the different connection options available to you. The one you use--modem, ISDN, cable modem, T1 line, or T3 line--depends on many factors, with cost being one of the greatest determiners. ModemsA modem is an electronic device that converts computer data into audio signals. These audio signals can then be transmitted over a normal phone line. At the receiving end, another modem converts the audio signals back into computer data. Modems can be internal, part of the original computer system, or purchased as external components. On either configuration, you have a jack for connecting your phone line and the data line from your computer. You also have to install special software on the machine to dial out with the modem connection. The speed of a current modem is measured in kilobits per second (kbps). The most common speeds are 14.4 and 28.8 kbps. Modems running at 33.6 kbps are currently available, although not many ISPs are capable of supporting this speed. ISDNISDN stands for Integrated Services Digital Network. ISDN lines are connections that use ordinary phone lines to transmit digital instead of analog signals. With digital signals, data can be transmitted at a much faster rate than with a traditional modem. ISDN converts audio signals--your voice, for example--into digital bits. Because bits can be transmitted very quickly, you can get much faster speed out of the same telephone line--four times faster than a 14.4 kbps modem, in fact. In addition, ISDN connections are made up of two different channels, allowing two simultaneous "conversations"; you therefore can speak on one channel and send a fax or connect to the Internet over the other channel. All these transactions occur on the same ordinary phone line currently plugged into your telephone. Your local telephone company can tell you if ISDN is available in your area. ISDN is a powerful tool for Internet communications, but it is not available everywhere. Traditionally, it has been used in urban business zones and large corporate settings with special digital switching equipment, but residential ISDN service is expanding rapidly. If you're shopping for an Internet service provider that offers you ISDN, be sure to consider the equipment costs. An ISDN line can offer you inexpensive, high-bandwidth connections, but you may have to buy special hardware that will allow ISDN to communicate with your home or corporate machines. Cable ModemsCable modems may be the next great leap in "at-home" connection solutions. It would be great to have the speed of the T1 line you may have at work available to your home PC. Even if you dial in to your office you are still held to the speed of the modem connected to your computer using the normal phone lines. Enter the cable modem. Your computer is hooked not to your phone line but to your coaxial television cable. Cable modems are targeted toward the Internet enthusiast with the need for speed. According to some accounts, the fastest cable modems will be capable of receiving data at 10 Mbps and sending it at 768 Kbps. The suggested fee for that cable-modem service may fetch about $30 to $40 monthly. Including the $600 price tag on the modems themselves, this will be one substantial upgrade that many veteran Net surfers are willing to make. Getting your hands on the hardware may be the easy part. Only certain areas are experimenting with the use of cable modems, but their use is rapidly expanding. Contact your local cable company to see whether it is planning to carry Internet access with cable modems. T1 LineA T1 line is a high-speed digital connection capable of transmitting data at a rate of approximately 1.5 million bits per second. A T1 line is typically used by small and medium-sized companies with heavy network traffic. This line is large enough to send and receive large text files, graphics, sounds, and databases instantaneously, and it works at the fastest speed commonly used to connect networks to the Internet. Sometimes referred to as a leased line, a T1 line is basically too large and too expensive for individual home use. T3 LineA T3 line is a super high-speed connection capable of transmitting data at a rate of 45 million bits per second. This connection represents a bandwidth equal to about 672 regular voice-grade telephone lines. A T3 line is wide enough to transmit full-motion, real-time video and very large databases over a busy network. A T3 line is typically installed as a major networking artery for large corporations and universities with high-volume network traffic. The backbones of the major Internet service providers, for example, are made up of T3 lines. Ten Questions for Your ISPIf you're treading into an unknown area trying to
find an ISP, arming yourself with some basic information is a good idea. The following
questions should help you decide which ISP is going to get your business. If an ISP skirts
the issue when you ask tough questions, strongly consider looking elsewhere. Just as in
any other business, you can find good ISPs and bad ISPs.
1. What is the price structure? 10. How many newsgroups can I access? Newsgroups enable users with similar interests to share their thoughts with each other. Star Trek fans, for example, can congregate in a specific newsgroup to discuss the characters, plots, and upcoming movies. Some ISPs offer limited newsgroup access; others have none at all. Commercial Providers: AOL, CompuServe, MSN, and ProdigyIf you have recently bought a computer magazine, chances are it came with ads (and probably software) for one or more of the major national online services: America Online (AOL), CompuServe, Microsoft Network (MSN), or Prodigy. Of these major online services, AOL is consistently rated best by magazines that compare the services. Figure 4.1 shows the AOL interface. CompuServe usually comes in second, with MSN, because it is still new and developing, in third place. For quick information, check AOL's Internet site. What Do These Services Offer?One of the best selling points of these services is their sign-up process. Connecting to them is usually simple: You install the free software they provide, follow the onscreen instructions, and you're connected. In addition to the vast resources of the Internet, these services also give you access to certain content that is not available to people who don't use the services. These ISPs, for example, have their own chat rooms, newsgroups, online shopping, special-interest groups, and searchable references that only subscribers to the service can use. What Do All These Services Cost?Two drawbacks really stand out about using these services: cost and cost. The first cost to consider is the amount AOL, MSN, Prodigy, or CompuServe charges your credit card each month. America Online (www.aol.com) now offers three pricing plans to better suit its users. The standard monthly package gives you unlimited Internet access for $19.95, with discounts down to $14.95 a month if you pay for two years in advance. Other offers include unlimited access to AOL's network through a local ISP for $9.95 a month, or the light-usage program at $4.95 for three hours of access. MSN, (www.msn.com), not surprisingly, is running very similar deals: One month of unlimited access to the Internet and MSN for $19.95. MSN underbid AOL by offering access to MSN content for $6.95 a month when you use your own local ISP. The company also has hourly service at $6.95 for five hours of connection time. Prodigy (www.prodigy.com) also offers an unlimited plan for $19.95. The company's secondary plan gets you 10 hours of online access for $10. To try out Prodigy's service you can sign up for one free month of unlimited access. The price structure is changing regularly in response to an extremely competitive market. These charges were available at the time of this writing, but the deals will no doubt change and others will take their place as the competition gets stiffer. The second factor that affects the cost of using one of these commercial online services is the dial-up access numbers. These national ISPs don't have local access numbers in all areas. If you live in an area not covered by a local access number, you may be forced to place a long-distance or local toll call whenever you log on. National ISPsOne way many people use a national online service like AOL is to get their feet wet and to learn more about the Internet. When they feel comfortable, they move on to a local provider that gives more options and often better service. National online services occasionally don't allow users with 28.8 kbps modems to run at 28.8 kbps. The modem banks they use may max out at 14.4 kbps, leaving those people with newer computers watching graphics download slowly as their wallets are being emptied. Be sure to check that the company offers at least 28.8 kbps connections in your area. If you like the idea of working with a national company but don't want to pay per-hour prices, a number of national companies now offer direct access to the Internet at a flat rate. Netcom, as shown in Figure 4.2, offers a $19.95 package that gives you unlimited Internet access and 24-hour support. Netcom advertises its services and specials on its Web site. AT&T has started offering Internet access, and Bell Atlantic reportedly plans to do so soon. Even AOL and CompuServe are getting in on the act. AOL also owns GNN, which is a national ISP, and CompuServe is debuting its Wow! service, featuring "unlimited" Internet access for $18 per month. Under such a price structure, you could theoretically log on to the Internet and never log off. Maybe you won't do that, but other people will--and when they do, that's one less modem available per person for all the other customers. Someone is losing out, and it's not the person who stays connected around the clock. The Local Connection: How to Find a Local ISPFinding a local ISP is getting easier all the time. Because ISPs are popping up all over the place, it's hard to talk to someone that hasn't done some of the work for you. Phone guides, friends, coworkers, and local computer stores are all good sources of information for finding your local ISP. I know this procedure will sound very low-tech, but the classics live: Tear your fingers from the keyboard and pick up the phone guide. Check the yellow pages for Internet service providers, and you should find a good starting point. Because new ISPs are always beginning to offer services, some may not be included in the phone guide. The next source for finding a local ISP is as close as your local computer store. Odds are that the staff of the store can recommend a few good services. The computer store may also have special deals with some local providers and may be able to get you a trial subscription or a discounted rate. It never hurts to ask. If you happen to be lucky enough to be investigating ISPs at the same time that a local computer club is having a computer show, you should know that providers flock to shows to have rate wars with the competition, and the winner is usually you. Here you have a collection of local ISPs in one area. Spend some time talking to the people who work on the system. Ask them some of the questions from the beginning of this lesson. If they really know their system, they should have no problem answering your questions. My final suggestion is to check the List (http://thelist.iworld.com), a Web site dedicated to listing many of the ISPs in the U.S. and Canada. This site, shown in Figure 4.3, even boasts a global ISP list categorized by country or country code. Use the List to find a local ISP.
