What is Wireless Internet?
As the name implies, wireless internet means the ability to go online (for communication, research, gaming, entertainment, social media, and so on) without being physically connected to a modem via a cable of sorts.
It is a type of technology that works across various devices; including everything from desktop computers to mobile phones.
3G and HSDPA
3G is 3rd generation technology that offers faster transfer of data and better voice quality than the 1st and 2nd generations.
HSDPA stands for high-speed download packet access and refers to a telephone-based protocol. It's basically an enhanced version of 3G. For that reason, it's also sometimes referred to as 3G+ or 3.5G.
Mobile connectivity is ideal for users that are not office bound. These remote or travelling employees can simply connect a USB dongle to their laptop to use this wireless internet access (where the signal permits).
GPRS (general packet radio service) is a type of mobile data that is standard for 3G technology.
