The high speed HSDPA data cards are getting popular by the day for broadband access on the move. But the biggest limitation of these cards is that they can only be used with just one device (a laptop or computer). And there is no straight forward way to share this connection across multiple machines. Imagine a scenario where you can actually share a data card connection across your phones, iPods, netbooks, PCs, etc. Sounds good?
To facilitate this need, a new breed of WiFi access points have arrived. These points come with one or two USB ports and can take one or two data cards, and instantly share the Internet connection over WiFi. Now any WiFi enabled device can be connected to it for accessing Internet.
These devices come with different functionalities. For instance, there is a device which can get power from a USB data cable, or a car charger or even from the wall socket. You can even use this device to turn your car into a WiFi hotspot. You can carry it in your bag with a battery pack and create a mobile hotspot with high speed bandwidth.
There are models which can take two USB data cards and even aggregate their bandwidth. This means you can get an Internet connection which has speeds of upto 6.2Mbps over WiFi by simply buying two HSDPA data cards.
