COMMISSION IMPLEMENTING DECISION  
of 8 December 2011  
amending Decision 2006/771/EC on harmonisation of the radio spectrum for use by short-range 
devices  
(notified under document C(2011) 9030)  
(Text with EEA relevance)  
(2011/829/EU)  
THE EUROPEAN COMMISSION,  
Having regard to the Treaty on the Functioning of the European 
Union,  
Having regard to Decision No 676/2002/EC of the European 
Parliament and of the Council of 7 March 2002 on a regulatory 
framework for radio spectrum policy in the European 
Community (Radio Spectrum Decision) (  1 ), and in particular 
Article 4(3) thereof,  
Whereas:  
(1) Commission Decision 2006/771/EC (  2 ) harmonises the 
technical conditions for use of spectrum for a wide 
variety of short-range devices, including applications 
such as alarms, local communications equipment, door 
openers, medical implants and for intelligent transport 
systems. Short-range devices are typically mass-market 
and/or portable products which can easily be taken and 
used across borders; differences in spectrum access 
conditions therefore prevent their free movement, 
increase their production costs and create risks of 
harmful interference with other radio applications and 
services.  
(2) However, due to rapid changes in technology and 
societal demands, new applications for short-range 
devices can emerge. These require regular updates of 
spectrum harmonisation conditions.  
(3) On 5 July 2006, the Commission issued a permanent 
mandate to the European Conference of Postal and Tele ­
communications Administrations (CEPT), pursuant to 
Article 4(2) of Decision No 676/2002/EC, to update 
the Annex to Decision 2006/771/EC in response to tech ­
nological and market developments in the area of short- 
range devices.  
(4) Commission Decisions 2008/432/EC (  3 ), 2009/381/EC (  4 ) 
and 2010/368/EU (  5 ) already amended the harmonised 
technical conditions for short-range devices contained 
in Decision 2006/771/EC by replacing its Annex.  (5) In its March 2011 report (  6 ) submitted in response to the 
abovementioned mandate, the CEPT advised the 
Commission to amend a number of technical aspects 
in the Annex to Decision 2006/771/EC.  
(6) The Annex to Decision 2006/771/EC should therefore be 
amended accordingly.  
(7) Equipment operating within the conditions set in this 
Decision should also comply with Directive 1999/5/EC 
of the European Parliament and of the Council of 
9 March 1999 on radio equipment and telecommuni ­
cations terminal equipment and the mutual recognition 
of their conformity (  7 ) in order to use the spectrum 
effectively so as to avoid harmful interference, demon ­
strated either by meeting harmonised standards or by 
fulfilling alternative conformity assessment procedures.  
(8) The measures provided for in this Decision are in 
accordance with the opinion of the Radio Spectrum 
Committee,  
HAS ADOPTED THIS DECISION:  
Article 1  
The Annex to Decision 2006/771/EC is replaced by the text in 
the Annex to this Decision.

( 1 ) Member States must allow the usage of adjacent frequency bands within this table as a single frequency band provided the spec ific conditions of each of these adjacent 
frequency bands are met. 
( 2 ) Member States must allow the usage of spectrum up to the transmit power, field strength or power density given in this table.  In conformity with Article 3(3) of 
Decision 2006/771/EC, they may impose less restrictive conditions, i.e. allow the use of spectrum with higher transmit power, f ield strength or power density. 
( 3 ) Member States may only impose these “additional parameters (channelling and/or channel access and occupation rules)”, and may  not add other parameters or 
spectrum access and mitigation requirements. Less restrictive conditions within the meaning of Article 3(3) of Decision 2006/77 1/EC mean that Member States may 
completely omit the “additional parameters (channelling and/or channel access and occupation rules)” in a given cell or allow h igher values. 
( 4 ) Member States may only impose these “other usage restrictions”, and may not add additional usage restrictions. As less restri ctive conditions may be introduced within 
the meaning of Article 3(3) of Decision 2006/771/EC, Member States may omit one or all of these restrictions. 
( 5 ) This category is available for any type of application which fulfils the technical conditions (typical uses are telemetry, te lecommand, alarms, data in general and other 
similar applications). 
( 6 ) For this frequency band Member States must make all the alternative sets of usage conditions possible. 
( 7 ) “Duty cycle” means the ratio of time during any one-hour period when equipment is actively transmitting. Less restrictive con ditions within the meaning of Article 3(3) 
of Decision 2006/771/EC mean that Member States may allow a higher value for “Duty cycle”. 
( 8 ) Social alarm devices are used to assist elderly or disabled people when they are in distress. 
( 9 ) This category covers, for example, devices for car immobilisation, animal identification, alarm systems, cable detection, was te management, personal identification, 
wireless voice links, access control, proximity sensors, anti-theft systems, including RF anti-theft induction systems, data tr ansfer to handheld devices, automatic article 
identification, wireless control systems and automatic road tolling. 
( 10 ) This category covers inductive applications used for radio frequency identification (RFID). 
( 11 ) This category covers inductive applications used for electronic article surveillance (EAS). 
( 12 ) This category covers the radio part of active implantable medical devices, as defined in Council Directive 90/385/EEC of 20 J une 1990 on the approximation of the laws 
of the Member States relating to active implantable medical devices (OJ L 189, 20.7.1990, p. 17). 
( 13 ) This category covers systems specifically designed for the purpose of providing non-voice digital communications between acti ve medical implants, as defined in footnote 
19, and/or body-worn devices and other devices external to the human body used for transferring non-time critical individual pa tient-related physiological information. 
( 14 ) This category covers transmitting devices which are placed inside the body of an animal for the purpose of performing diagnos tic functions and/or delivery of therapeutic 
treatment. 
( 15 ) This category includes applications which connect personal audio devices, including mobile phones, and the automotive or home  entertainment system. 
( 16 ) Applications for wireless audio systems, including: wireless microphones; cordless loudspeakers; cordless headphones; cordles s headphones for portable use, e.g. portable 
CD, cassette or radio devices carried on a person; cordless headphones for use in a vehicle, for example for use with a radio o r mobile telephone, etc.; in-ear monitoring 
and wireless microphones for use at concerts or other stage productions. 
( 17 ) This category covers applications used for determining the position, velocity and/or other characteristics of an object, or f or obtaining information relating to these 
parameters. 
( 18 ) Tank level probing radars (TLPR) are a specific type of radio-determination application, which are used for tank level measur ements and are installed in metallic or 
reinforced concrete tanks, or similar structures made of material with comparable attenuation characteristics. The purpose of t he tank is to contain a substance. 
( 19 ) The power limit applies inside a closed tank and corresponds to a spectral density of – 41,3 dBm/MHz e.i.r.p. outside a 500 l itre test tank. 
( 20 ) This category covers applications used to control the movement of models (principally miniature representations of vehicles) in the air, on land or over or under the 
water surface.’EN L 329/18 Official Journal of the European Union 13.12.2011
