Bluetooth: Global Certification Requirements Paul G. Didcott Understanding certification requirements can speed time to market for Bluetooth products. Bluetooth is a low-power wireless technology deployed with radio equipment operating on the widely used 2.4 GHz spread-spectrum band. Bluetooth was developed to create an open specification for short-range radio for use in the mobile and business market segments. The technology provides transparent connection for mobile computing devices via a wireless modem, and documents can be sent at speeds up to 1 Mb/sec. Bluetooth can provide the same wireless connectivity expected from third-generation wireless (3G), as well as voice capability, at lower costs to the consumer. Unlike 3G, Bluetooth is available now and its first products are already appearing on the market. 3G products may still be two years away. Because users moving between locations are more likely to use data transactions at the starting and end locations rather than in transit, the potential for wireless local networking technology—Bluetooth—within offices and as a competitor to 3G is immense. As manufacturers address the issues of equipment development and the new wireless connectivity protocol, one important factor to consider is time to market. This issue can best be addressed by understanding the Bluetooth qualification process. This article identifies the common product certification requirements applicable to equipment using Bluetooth, which will have a significant effect on a products time to market. Figure 1. Product certification hurdles. Certification Two main sets of approvals requirements must be addressed before products using Bluetooth can legally be placed on the market. These requirements are the Bluetooth Qualification Program and product certification. Figure 1 shows the main certification hurdles for equipment incorporating Bluetooth.
