Many people these days travel for work and leisure purposes and like to carry a portable PC with them. This can be useful to have available for a number of reasons. If you want to use the internet while doing this there are a few options available. While using a Wi-Fi hot spot at a cafe or hotel is an option this can only be utilized when you are in a suitable location. A more convenient way of connecting to the internet can be to use a wireless air card and these are widely available these days.
A wireless air card is basically a portable modem which uses cell phone technology rather than telephone cables to connect to the internet. It tends to be designed for use with portable computers such as notebooks, although it can be used with a desktop computer. It is a small card sized device which either connects into the PC card slot of a portable PC or they can also typically be connected using a USB adapter. Once connected the PC can then be connected to the internet through the cell phone network and this means that you can basically have an internet connection anywhere there is a cell phone service. The only real restriction on its use is that the area where you are trying to connect must be directly covered by the air card provider or indirectly covered through roaming contracts.
The benefit of using a wireless air card is that you can have access to the internet wherever you are rather than trying to have to find a convenient hot spot location to connect. Many people require an internet connection for working purposes and using an air card means that whether you are sitting in the back of a taxi, on a train or in a clients office you are able to establish an internet connection. It can also be useful for those that travel a lot for leisure as connection to the internet and the entertainment this brings can be a good way to relieve the boredom of travelling.
Most of the cell phone providers will have wireless air cards available and generally these can be purchased on monthly contracts which typically provide unlimited access. In many cases the air card will be provided free of charge when you open an account. Cell phone providers such as Sprint, Verizon and AT&T are examples of air card providers, although many cell phone companies offer the service.
When deciding which wireless air card provider to choose the first thing to look at is the coverage that they provide for their service. Different areas of the country can have different cell phone services that work best and it is common sense to pick a service that provides good coverage of the areas in which you live and travel. Most cell phone companies have maps on their website showing the areas they cover and this can be a good starting point in terms of finding a good service.
If you are looking to purchase a wireless air card there are a few online companies which can be used to find a comparison of the various devices and contracts on offer. Cheap Aircards is an example of this and they have a range of air cards from various companies. Typically the air cards on offer are free, with the monthly cost of an account generally starting around $40 per month.
If internet access is important to you when you travel then a wireless air card is the best option to choose. It ensures that no matter where you are you should be able to connect your portable PC to the internet through the cell phone network.
