Well there is no skepticism in saying that Bluetooth Dongle have proved to be effective solutions for almost all gadgets – notebooks, smartphones just to name a few.  In simple words a dongle is nothing but a small piece of hardware that helps in transferring data from one gadget to another at a fast speed. Most of us get perplexed in buying one due to enormous choice available in the market. Nothing to ponder about any more as here I present the three most significant factors to consider before buying a USB Dongle.

Speed is important

The main work of dongle is transferring any data by securing wireless connection through Bluetooth devices such as mobile phones, PDA and notebook. In this context its speed becomes a very important factor to watch out for. 2.1Mbps is considered to be a reasonable speed. Ofcourse this largely depends upon the Bluetooth Compliance Technology in use.

Range

Range does matters as many USB dongles are capable of transferring information only if they qualify certain distance limits. Up to 10 metres is reasonable but if you are looking for more a range up to 30 metres will be a perfect to meet your requirements. This too again largely depends upon the Bluetooth Compliance Technology in use.

Design

As far as design factor is concerned it is always recommended to carry a light and compact Bluetooth dongle to avoid any bulk and inconvenience. A weight around 35-45 g is a decent choice to make for.

Other factors include Radio Frequency Band; Operating Temperature; Synchronisation; and Power Consumption.
