A new version of Bluetooth is making its way to consumers (sooner or later). This new version dubbed Bluetooth Enhanced Data Rate (EDR) increases data transmission by compressing the data better. Bluetooth EDR will be compatible with the older Bluetooth (1.2).
Bluetooth communications are set to get rather faster with a new version of the specification that takes its data throughput 2.1Mbps in the offing. The new version, Bluetooth Enhanced Data Rate (EDR), is offered as a "prototype specification" by the Bluetooth Special Interest Group (SIG). The technology increases data transmission by compressing more data into each packet rather than by increasing the rate at which packets are sent. Today's devices support speeds of up to 712Kbps.
Bluetooth EDR will use existing Bluetooth 1.2 technology for connecting devices and sending data, so older devices will still be able to communicate with machines supporting EDR. The SIG says EDR will consume less power than the current version - it reckons EDR devices will eke out battery power for twice as long as Bluetooth units do today. And the new specification also provides improved facilities to use several functions or devices simultaneously, due to more available bandwidth.
