Channel spacing: 25 kHzIndividual transmitters may combine adjacent channels for increased bandwidth up to 300 kHz.Other techniques to access spectrum or mitigate interference, including bandwidths greater than 300 kHz, can be used provided they result at least in an equivalent performance to the techniques described in harmonised standards adopted under Directive 1999/5/EC to ensure compatible operation with the other users and in particular with meteorological radiosondes. 1 November 2009 [1][1] This category covers the radio part of active implantable medical devices, as defined in Council Directive 90/385/EEC of 20 June 1990 on the approximation of the laws of the Member States relating to active implantable medical devices and their peripherals (OJ L 189, 20.7.1990, p. 17). Relevant European Harmonised Standards - EN 301 839 (402 – 405MHz) and EN 302 195 (9 – 315 KHz)

SRD/MG considered an allocation for Low Power Active Medical Implants (LP-AMI), 20 MHz, 2 360 MHz to 3 400 MHz This has resulted in First band being studied is 2483.5 – 2500 MHz Other Exempt Spectrum that may become available in future

Amendments to the previous EC Decision include: –The introduction of a new mitigation technique (TPC) and new limits to allow the use of UWB for both automotive and railway applications. –The introduction of a new mitigation technique DAA to enable higher power usage by UWB devices operating below 4.8GHz and above 8.5 GHz. –The introduction of new limits for Building Material Analysis (BMA) devices. ETSI still working on amendments to EN 302 065 v1.1.1 which is the harmonised standard that covers short range UWB devices for communications applications operating in the frequency ranges from 3.4 - 4.8 GHz and 6 - 10.5 GHz. Amendments to include tests and limits for TPC for automotive and railway applications and generic DAA mechanism. EN 302 435 is the harmonised standard for Building Material Analysis (BMA) technologies. Ofcom will publish a consultation very soon on how we intend to implement these changes in the UK law. European and UK developments for UWB
