The 2 greatest inventions

1. Bluetooth Pioneer:
In 1994 Ericsson asked Haartsen to develop a radio link between a headset and a cell phone. Early Ericsson and several other companies (Nokia, Intel, IBM and Toshiba) realized they were all working on similar technologies.  These firms established the Bluetooth Special Interest Group, standardizing their efforts so that devices made by different companies could talk to one another. The last year Microsoft, Lucent, Motorola and 3Com joined, and more companies have followed suit.

2. 2003 InfoWorld Innovator: In 1994, as cellular technology and sales of cellular handsets were taking off, executives at Ericsson, one of the handset market leaders, began casting about for ways to differentiate its phones in a crowded market by adding real value. 


That year, Jaap Haartsen, was given a simple directive: Devise a way to send and receive data to cell phone accessories over handsets. The technology used for wireless handsets was not suitable for data, according to Haartsen, so he needed something more powerful.

 
Using frequency hopping, Haartsen was able to overcome the need for the device to always be on, always listening for another device that wants to connect. "Bluetooth units are just floating. They are not in standby. They are always there".

Jaap Haartsen said that Ericsson hopes to increase the data rate from its current 700Kbps to 11Mbps. "We want to increase the data rate and functionality of Bluetooth by reducing latency. We will have a mode within Bluetooth where you can negotiate for a higher data rate."
