Description

Mobile broadband, whether accessed via dongle or mobile phone, involves the use of 3G services. 3G Technology is made possible by two complimentary technologies HSDPA and HSUPA (high speed download, and upload packet access, respectively). In theory, these technologies are designed to give the user mobile broadband speeds of up to 7.2Mb speed downloads and uploads with speeds of up to 1.76Mb. In practice however, such speeds are only available in certain areas. It is likely that access to these speeds will become more wide-spread in the future. Today, mobile broadband dongles that include the USB sticks and data cards are the norm and are what the people are currently using to access the mobile broadband, 3G laptops are slowly becoming popular. It is with this Growth in the area that has led to the innovation that we currently see in the market and the indicator that the leading Top 10 Broadband has used to predict that mobile broadband will account for over 50% of broadband sales in the years to come There are two basic technologies used to operate cell-phone networks: Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA). In Europe and Asia the dominant technology is GSM whereas CDMA is more common in the United States. On a technical level, the two systems differ in the way each technology shares space on the radio spectrum. GSM and CDMA therefore use different algorithms that allow multiple cell phone users to share the same radio frequency without interfering with each other. Mobile broadband is also known as 3 G- third-generation cell-phone technologies). Both GSM and CDMA have developed their own 3G technology solutions for delivering high-speed Internet access to mobile devices. CDMA-based mobile broadband technology is called EV-DO. EV_DO means Evolution-Data Optimized or Evolution-Data Only. What is most distinguishing of EV-DO is that it runs over a part of the cellular network devoted entirely to data. Since Voice calls require a lot of bandwidth to maintain sound quality, separating voice from the data channel from allows maximum data transfers and provide higher-speed access to e-mail, the Internet and multimedia. The downside is that you can’t access the Internet and other data tools when talking on your cell phone. EV-DO advertises average speeds of 300-400 Kbps (kilobytes per second), the equivalent of DSL. One needs a device that’s already loaded with EV-DO hardware (like a Blackberry or other smart phone) to use an EV-DO network. However, one can use a special network card that plugs into your laptop. Most of the cards connect via USB ports or other standard PC card slots. When inserted in the ports, they act as antennas for mobile broadband signals. Fastest download and upload speeds, can be attained when one is within range of the EV-DO cellular signal. Otherwise, you’ll be bumped down to the 1xRTT (Radio Transfer Technology) standard, which broadcasts at speeds between 60 and 100Kbps. GSM’s has come down with a rival to EV-DO with what is called HSDPA (High-Speed Downlink Packet Access). This technology Unlike EV-DO, can handle both voice and data transfers.
