Cable Modems

A standard modem’s job is to convert data from its digital form to analog form, which are then transferred over a phone line and reverse done while receiving data from the telephone line to your computer. By doing both modulating and demodulating the data signals, it is called to be a Modem.

A broadband modem is quite different from those of dial-up modems. You need it when you take a broadband service for the first time. Usually providers offer modem along with you package or may ask you to have a modem at extra cost. Anyhow, getting the modem from your broadband provider should be safe being supported by your provider and should work fine with the setup.

In case your provider does not offer a modem then you can get a modem of your choice. There are wide types of modem out there and it is good before to check with your provider for a suitable modem. If you are in preparation to set up a network to share your internet connection then you require a router modem.

Broadband modems are still limited to utilize analog/digital conversion. But most recent advanced modems are capable of modulating/demodulating hundreds of channels simultaneously. Also many broadband modems together include the firewall features and functionality of a router.

The propagation of cable broadband, along with ADSL, has steered well the broadband Internet access in the developed world. However, modem for a cable broadband much differs from an ADSL modem. Cable broadband primarily uses the unused bandwidth on a cable television network to deliver speeder broadband Internet access. A cable modem so is a different type of modem that is designed to carry on the data signals over network designed for cable television.

ADSL and Cable modems differ little by the way it works and both are superior alternatives to dial-up internet. Both offer a snappy pace to transfer data packets to the servers. But, there is wide different in bandwidth between ADSL and Cable internet. Speeds at which data are send and received vary between cable and of ADSL modems.

Cable modems mostly run at a speed of 3-6 Mbps in downstream and in upstream 0.3-0.4 Mbps. Comparing to Cable modem, DSL modem offers less speed and varies between service packages. Service quality also depends on your location from your local exchange. A dial-up modem can run at a speed of 56 Kbps. Irrespective of broadbands having their own advantages and disadvantages, modems take the central most part in it to provide you the high-speed internet.

Sharing an internet connection between two computers in your home is very easy with all this new technology. If you own a broadband modem or one that is supplied from your internet service provider you can most probably have two computers connected to it without needing a router. This can save you money by not having to buy that extra network equipment. 

Quick tips on how to connect two computers to one modem:

If you look at the back of your modem, it may have a USB (blue) and a ETHERNET (yellow) port. See a detailed picture how to connect two computers to one modem

**My service provider, Telstra Australia, supplied my modem to me. It came with an installation disc, which we will need to use to connect to the modem through the USB.

**If you have a similar modem to what I have described, you can connect two computers off the one broadband modem and thus both accessing the internet.

One can connect through the USB port and the other through the Ethernet.

**A USB cable and and Ethernet cable should come with the modem, however to connect the second computer you may need to buy a longer Ethernet cable as you do not want the two computers sitting right next to each other. Get a blue cable.. NOT red.

**To connect a computer to a broadband modem through USB, it is recommended that you use the installation cd. It will ask you to choose how you want to connect and you select USB. Make sure you know your user name and password for your internet service provider.

**To connect the second computer to the same modem but through the Ethernet, just plug it in…It usually works straight away. If it does not, use the installation cd, but choose to connect with Ethernet instead of USB.

Notes:

1..If you do not have an installation cd, phone your internet service provider and they will send one to you.

2..If you run into any problems, phone your internet service provider and they will help. You are allowed to have more than one computer connected to the internet. You can also get more networking tips at tips4pc.com.

Modem, a term derived form Modulator-Demodulator used to stand for a device that allowed a computer or terminal to transmit data over a standard dial-up telephone. This description of a modem is inadequate and was suitable only until the late 1990s. Since the advent of high-speed cable and DSL connections, modem now refers to devices that offer low-speed dial-up or high-speed broadband. Taking technology one step ahead, the wireless 3G modem provides global wireless access to the Internet and e-mail.

USB wireless 3G modem creates connection of computers and private networks with the Internet as the primary or back-up route. It is especially suitable for desktop users seeking permanent wireless Internet connection and users in rural areas where no other means of broadband Internet are available. It is also equally suitable for users on the move who want to take their connection with them all the time.

As mentioned above, the wireless 3G modem provides global wireless access to the Internet and e-mail on HSDPA (High Speed Downlink Packet Access) capable UMTS networks. With a speed of up to 1.8Mbps down and 384kbps up, it enables users to enjoy access to wireless connectivity similar to DSL or cable modems. In addition to supporting high-end HSDPA technology, the wireless 3G modem is also compatible with UMTS, EDGE and GPRS networks.

This capability of the wireless 3G modem makes it an ideal device for operators planning to upgrade their networks to HSDPA as it supports currently deployed wireless broadband technologies (WCDMA 2100MHz, EDGE Class 10 Quad band). By virtue of this technology, you can get access to the Internet using your 3G mobile phone as a modem by simply connecting your handset to your PC with a USB cable. What more, while you are browsing the net, you can still use your 3G mobile to make and receive phone calls or send and receive text messages.

If you thought dial-up modems were going the way of the Dodo bird, there are still die hard analog modem users out there. Not only are thousands of Internet surfers still using dialup, but businesses often make the best use of dialups for nightly back up purposes.

A recent survey by Pew Internet (http://www.pewinternet.org/PPF/r/184/report_display.asp) provided an insight into the current increasing market of high speed internet access from homes while revealing dialup users loyalty. Close to double the number of Americans who access the internet at their homes say they use broadband connections rather than dial-up, according to data released by the Pew Internet & American Life Project in late April 2006.

Statistics show American adults with broadband access at home increased 40 percent from 60 million to 84 million people in the year leading up to March 2006 – two times the rate of growth from the previous year according to another recently released Pew study. The majority of users surveyed, 62 percent, reported accessing the Internet from some form of high-speed service, while 34 percent stated they still used analog (dialup) modems – and they would continue to use dialup. That translates close to 25 million additional Americans are using broadband in 2006 than in 2005. With figures like that, it might seem like the demise of dial-up is knocking at the industry door.

Don’t plan dialup’s funeral just yet. Apparently, there is still a market for people who’s online needs are easily met with analog modems. The study also revealed that the majority of dial-up users, 60 percent, told the Pew pollsters that they had zero interest in upgrading to broadband. Another barrier analog modem cyber-surfers face: broadband is simply not available in their area. Dialup internet access is often the only choice for rural town internet access.

In addition to availability, the research hypothesizes that many dial-up users reject high-speed Internet services because of having to pay twice the price. The average monthly fee for cable Internet access was $41, DSL service was $38, where dial-up was only $18 per month. For web surfers everywhere, the monthly bill is enough to justify staying on dialup internet access.

With new technology and different business models, dialup providers are offering faster connection speeds than ever. By blocking pop-ups and other advertising images, users can often get the speed they need for email and web browsing. Like many services, it depends on what you want to use it for. Dial-up is still usually not fast enough for those wanting to download 100’s of MP3 and movie files.

While it does not presume to be a market for fast growth, the dialup internet providers who understand these user’s needs will continue to have a stable businesses for the casual internet user. If getting email and browsing text web sites is main need, dialup may very well be the best solution. An additional phone line is not always needed because the dialup user’s habits do not justify it. There are also technologies like “catch-a-call” which work in tandem with a user’s online connection and call waiting to keep from missing calls.

Another market the dialup access providers are pursuing is dialup connections to upload nightly receipts through an internet connection vs. paying long distance charges for a direct connection. While long distance costs have plummeted in the past 10 years, there is still a great advantage to making that local call each night to a dialup ISP instead of paying long distance charges.

With committed customers on the books and new ones dialing into the world wide web, it appears dialup ISPs can keep answering the call for online service in the foreseeable future.

Are you a road warrior that still needs to send out and receive emails and have access to the internet? Are you tired of wasting your money for data download fees on wireless internet plans that are a hassle to connect and don’t always work?

One solution to your problems may be a wholesale 3G or EDGE Modem, the latest in internet connection technology in the wholesale market.

Any business person that’s spent a lot of time on the road will tell you that trying to keep their laptop connected to the internet has never been an easy endeavor. The plans are expensive and dial up and broadband connections are never capable of giving you universal coverage.

On the release of smart phones, like the 2G iPhone, the Blackberry and the HTC Mogul, saw ingenious businesspeople use the data allotments set aside for their mobile phones to hook their notebooks to the internet. They do this by ‘tethering’ their phones to their computers.

However, this isn’t an ideal solution for three reasons:

1) You’re required to buy expensive hardware in the first place

2) For arrangements where you get a free (or cheaper phone) you’re locked into a potentially expensive roaming contract.

3) It means you need two phones as one is dedicated to running the laptop’s internet connection.

Wholesale electronic manufacturers have noticed the move towards tethering and have started making EDGE and 3G modems, which use GSM SIM cards as the driver.

These new types of wholesale modems take the idea of tethering to the next level for the following reasons:

You’re not wasting money on extra features: The problem with buying a phone that will just be used to tether to a laptop or notebook is that it’s probably going to be a smart phone. It will probably likely to be a lot more expensive than other phones and have a whole lot of features including a camera, the ability to store and play MP4 and MP3 files. Amongst other things.

If you want a phone that acts like a mini laptop then that’s great. But if you’re happy with your laptop and just want to connect to the internet then you’re getting a lot of useless features that cost you too much money and eat up valuable battery life. That is where wholesale EDGE modems really shine. Wholesale 3G and EDGE modems are a fifth of the price of smart phones (at the very least) and just do one thing… connected you to the internet.

They’re easy to connect: hooking up a dialup and broadband connection isn’t exactly the easiest process the notebook and tethering your phone isn’t a walk in the park either. Setting up wholesale EDGE modems is just a plug in and play operation.

Good coverage: Anywhere you can get a cell phone signal you can get internet connection. This means that in places like Europe and countries like Japan, New Zealand and the more populated areas of the US have almost unbroken internet access.

You can use more than one phone company: Any international businessperson will tell you that there’s nothing worse than trying to keep a connection to the internet going when you’re dealing with one provider in different parts of the world. With wholesale EDGE modems changing which provider you use is as easy as putting a different GSM SIM card into the phone.

So, if you think you’re overpaying for an unreliable internet connection that’s a hassle to set up then you owe it to yourself to check out what wholesale EDGE modems offer you and your notebook connection.

It seems that some people are just never happy with the speed of anything. They approach their computers Internet speed the same way that a high school kid does his car, always wanting more. For others who rely on their computer for their income, time is money and in those cases the sooner they can get their work done, the sooner they get paid. The good news for anyone that wants to see things happen faster when they are online is that the means are now available to kick-it-up a notch for more speed on their computer.

Online Services Now Specialize in Speed

This is because, there are now online services that can help you to get your speed increased, no matter what type of Internet service you are connected to. This means that even people that are still using standard dial up service can get things going quicker when they are using their computer online. The first step however, is to determine your computers actual modem speed and then work from there.

Test Your Download and Your Upload Speed

The truth is, that you can test your modem speed yourself. This is done by simply downloading a file of a specific size and timing the procedure while it happens. However; this doesn’t account for your upload speed, which is far more difficult to test. An online service can test both of them by sending you a file of a specific size and then seeing how long it takes for your computer to download it and then upload it back to them.

Retest After Your Upgrade

After this is done, for many people the first step is to install optimization software, which will increase the speed even if you are using dial up service. If you have broadband however, you will need a tweak utility such as TCP Optimizer. Either way after you have completed your upgrades, you will then want to have your modem speed retested to see how much of an improvement has been made.

Whether you operate a home business or a large corporation, your lifeline to the world is the telephone line. With out it you would be out of business. Phone lines are very important, but they are also expensive, and as a valuable resource, they should be managed wisely. An intelligent phone switch will manage your calls and save you money month after month.

Line-sharing technology can cut fixed costs on your monthly bills and give you the advantage of more control over your telecommunications system. Sharing phone lines for voice callers, a fax machine, a modem, and other devices is both feasible and cost-effective. Automatic call processing technology makes this possible as well as profitable.

Automatic call processors save the monthly cost of having dedicated phone lines for your fax, modem, and/or voice calls. By effectively using your phone lines, you can eliminate one or more of them with the help of a “smart” phone switch.

When installed on your system, the line-sharing device automatically routes calls over one or more lines to multiple devices. When a fax call comes in, the switch automatically sends the call to your fax. If it’s a data call, it’s routed to your computer. Or if the caller is a human, it’s routed to your phones, phone system, or answering machine. The correct device answers automatically and no other devices will ring. A smart switch pays for itself in a few months and keeps on saving you money for years to come.

Cut Fixed Costs

A smart switch can save you 1-9 lines per unit in phone charges, and multiple-line devices can save you even more.

A computerized call processor can automatically tell whom the call is for and whether the caller is a person or a machine. Fax switching frees up the fax line for other uses when the fax is not in use.

Distinctive ring processors allow up to 3 phone numbers on the same line.

Tone Detection call processors allow up to 9 devices to share a single phone number.

Modems can share lines with other modems, fax machines, voice systems or any phone-connected equipment. You can poll multiple modems over one phone line in one call automatically. Line Sharing will save you thousands over the life of the equipment.
