Broadband USB Modems are used for accessing internet connection wirelessly. The device is compact and can overcome the flaws of earlier methods. Just by plugging the gadget into the USB port of laptops, users can start accessing internet connection. There is no longer the need of connecting by means of long drawn wires or by ‘phone dial ups’ for getting connected to the internet.Internet accessibility is thus made easy with broadband. The modems are available with several companies such as Vodafone, 3 Mobile, O2 mobile and others. These service providers of broadband bring quality service and users can really enjoy availing broadband networks. It is also becoming increasingly common to find a free modem with broadband service providers. Most of the UK based broadband providers are known to supply a free modem to their customers. However, if people want to get it from marts, they can find it at amazingly low price.

Toronto, Canada – GAO Research Inc.  has launched its economical, flexible and reliable Soft-modem for Set-Top Boxes (STB). The soft-modems are designed to be compliant with specific ITU-T standards and yield comparable reliability and quality to traditional hardware modem chipsets. GAO’s soft-modems run on a DSP or microprocessor along with other control software and require an analog front-end.

GAO’s modular, re-locatable and reentrant soft-modems support multi-channel capability and improved for all common embedded hardware platforms. They are operating within a multi-tasking environment or as a stand-alone task and are optimized for fixed-point arithmetic. They support most commercial analog front ends (AFE) as well as various discrete DAAs with codes, depending on the application.

GAO’s soft-modems are the ideal solution for satellite STB units. The lower speed modems, using V.22 or V.22bis standards, provide a speedy hand-shaking process and a sufficient bit rate to complete the typical data transaction requiring relative low bandwidth within seconds. The higher-speed modems including V.34, V.90 and V.92, have maximum downstream data rates of 33.6kbps, 48kbps and 56kbps respectively. These high-speed modems are suitable for the transfer of data for interactive STB applications that require real-time response such as interactive gaming and Internet/email/IM access.

GAO’s high-speed soft-modems are typically deployed in high-end satellite STBs in order to support advanced interactive features, to meet desirable response times and higher bit rates..

Don’t you find it annoying that whenever you are in a middle of research or online surfing, the connection suddenly stops? If you’ve experienced that a number of times, perhaps the problem might lie with the cable modem. And what you can do perform a few tweaks on the cable modem in order to optimize its operation.

Say the cable modem on your computer gets disconnected after a few minutes, then here’s a cable modem tweak that can help you address the issue. One reason this thing happens in your computer is that this is Windows XP-related. On the Windows XP, there is an option that allows the computer to turn off the USB device in order to save on power. Now what you can do is to disable this option. Just click on the start button and highlight the My Computer icon and select the option that says properties. A window will then appear with the system properties. Navigate the window by clicking on the hardware tab and press the device manager button. Expand the serial bus controllers and double click on the USB root hub. You’ll now see the Power Management tab and uncheck the ‘allow the computer to turn off the device to save power’. If the computer displays a number of USB root hub, then make sure that you repeat the same steps for that same number of hubs. Often a cable modem that disconnects after a few hours can be remedied by performing these two steps. One cable modem tweak that is possible is by disabling the hibernation. You can right click on the desktop and click the screen saver tab. You’ll notice the power button of the display properties dialog. Click that one. Another dialog box will appear and you’ll be shown the hibernate tab. Use this box to uncheck the box beside the enable hibernation. Another good step is to disable the Windows Messenger. On the start button, select run and input the words gpedit.msc. Proceed to the Computer Configuration then select the Administrative Templates, then straight to Windows Components and on to Windows Messenger. Don’t run the messenger, just go to the properties and check the box near it to enable.

WiMAX has enabled convergence of mobile and fixed broadband networks through a common wide-area radio-access technology and flexible network architecture. Since January 2007, the IEEE 802.16 Working Group has been developing a new amendment of the IEEE 802.16 standard (i.e., IEEE 802.16m) as an advanced air interface to meet the requirements of ITU-R/IMT-advanced for 4G systems, as well as for the next-generation mobile network operators.

With WiMAX indoor traffic taking up more than 80% of total WiMAX traffic, WiMAX Operators are faced with the pressing need to improve indoor coverage. Contrary to common belie f that WiMAX Modems are merely variables in the WiMAX subsystem, this whitepaper discusses how WiMAX Modems can play a major role in the subsystem, particularly in improving indoor coverage.

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.
