scope:

The present document describes the current Wideband Data Transmission Systems (WDTS) and technologies that have been developed over time compliant with the existing provisions in Annex 3 of ERC Recommendation 70-03 [i.1] for the 2,4 GHz band. In addition to using wideband modulation techniques, these systems use a polite access/sharing mechanism (which also includes mechanisms restricting the Medium Utilization) in order to facilitate sharing among the wide variety of Wideband Data Transmission Systems operating in this band. The details of the polite access/sharing mechanisms are described in ETSI EN 300 328 (V2.2.2) [i.8]. Products using these technologies that are available in Europe are required to be compliant with the existing provisions in EC Decision 2006/771/EC [i.2] or national regulations based on the ERC Recommendation 70-03 [i.1].

For the various Wideband Data Transmission Systems covered by the present document, the following information is included:

• Market information.

• Technical information [including expected sharing and compatibility issues].

• Regulatory issues.

The information on the various Wideband Data Transmission Systems in the present document can be used to support the work within CEPT in the context of updating the EC Decision 2006/771/EC [i.2].

During the time the present document was developed, no proposals for new systems were submitted. However, it was mentioned new systems are being developed which may lead to a future activity to revise the present document or to develop a new System Reference document.
