Mobile broadband is defined as broadband access (e.g. cable and DSL) in the cellular environment. Wireless internet has been around for a number of years but mobile broadband has only recently (within the last few years) become popular due to the costs involved. WiFi is quickly losing its edge due to the restraints that comes with it. The problem with WiFi is that if you want to connect, then you must be in a WiFi hotspot and, crucially, you must be stationary. You could say that a WiFi connection is similar to a cordless telephone, whereas mobile broadband is like the mobile telephone, enabling fast internet access, anywhere. Mobile broadband has changed the way businesses operate. Mobile broadband communication now means businesses can have virtual conferences and meetings with their employees and clients anywhere in the world and can quickly update clients and employees with new information.
Mobile broadband uses the same technology as mobile phones, through radio waves and frequencies. The way mobile phones work is by sending and receiving audio data through the telephone masts. Mobile broadband works in almost the same way, though the data that is transferred contains packets of web pages, emails, audio and video data; all sent and received through the telecommunications towers.
Mobile broadband was initially quite slow compared to a WiFi connection, though constant improvements have meant that speeds have increased dramatically, listed below are the chronological order of mobile broadband advancements:
-2.5g, or EDGE as it is more widely known, was the first form of mobile broadband, though take up was low as the packet transfer speeds were so low.
-The second format that was introduced was 3g, known on GSM formats as UMTS. Though transfer speeds were also quite slow, it began to offer users an alternative to using WiFi.
-HSDPA was the next incarnation of mobile broadband which offered slightly increased speeds over WiFi.
-Currently HSUPA is the standard, with bandwidth similar to WiFi speeds.
A new format that is currently being developed is called WIMAX. WIMAX, or 4g, will be able to give users broadband connection speeds faster than the WiFi speeds currently offered in popular hotspots. It will also have a very wide network coverage ratio, which means more people being able to access the internet from more places. It is becoming commonplace for laptop manufacturers to incorporate mobile broadband receivers into the design of new notebooks, and with the huge increase in speeds of mobile broadband over the last few years; internet via cable may become a thing of the past.
