The dissemination of information is paramount to the world's economy and really human evolution. The distribution of information stared with books, eventually moved to computers and then came the internet. The internet allowed people worldwide to communicate and send information or files across oceans within seconds. As we have moved further and further into the 21st century, the internet has gotten faster and also more mobile. Internet mobility started with advent of wireless broadband internet. Wireless broadband internet sent broadband signals through a router rather than a LAN cable. This allowed consumers to travel around their house or office freely without cords and still remain connected to the internet. However, wireless broadband has its limitations, most noticeably, in the realm of range. Even the best routers can only send a signal that can travel 300 to 350 feet. But now there is mobile broadband internet that allows you to receive an internet signal no matter where you are. In addition, with the advent of 4G mobile broadband networks, you can remain mobile and still receive speeds comparable to those received through DSL or cable land line connections.

Although you may be intrigued by this kind of technology, you may not understand how it works. While it may sound complicated, it is actually quite simple. Mobile wireless internet works a lot like a wireless router. A wireless router receives broadband signals from your local internet provider via a DSL or cable modem. It then transmits the broadband signal out into the world through signals that travel through the air. Your computer, if it has a wireless card, will receive this signal and allow you to surf the internet at broadband speeds without a land line connection. Similarly, mobile broadband networks use a "wireless" tower as a router. The tower receives a broadband signal from your mobile internet provider and then transmits that signal out into the air. If you have a desktop or laptop with a built-in modem capable of receiving this signal, you will be able to receive this signal and connect to the internet. If you don't have a built-in modem with this type of capacity, a USB modem can be purchased through your mobile internet provider. While they are an added expense, they are normally quite affordable; especially when the convenience factor of mobile internet is taken into account.

Currently, 4G networks provide the fastest mobile internet on the market. However, the added speed comes at a price. 3G networks are also widely available for the consumer who needs mobile internet but does not want to pay the steep price that 4G networks charge. Both networks operate in a similar fashion; however 3G networks were created primarily for use via cell phone, while 4G networks were created with laptop users in mind. Mobile wireless networks allow you to take your notebook on a road trip and maintain an internet connection throughout the trip. The benefits of mobile and especially 4G mobile internet are numerous. Along with being easy to use it can keep you in touch with the world no matter where you are.
