Foreword
This Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical Committee
Broadband Radio Access Networks (BRAN).
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC [i.3] (as amended) laying down a procedure for the provision of information in the
field of technical standards and regulations.
The present document is intended to become a Harmonized Standard, the reference of which will be published in the
Official Journal of the European Communities referencing the Directive 1999/5/EC [1] of the European Parliament and
of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual
recognition of their conformity ("the R&TTE Directive").
Technical specifications relevant to Directive 1999/5/EC [1] are given in annex A.

National transposition dates
Date of adoption of this EN: 2 December 2008
Date of latest announcement of this EN (doa): 31 March 2009
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 30 September 2009
Date of withdrawal of any conflicting National Standard (dow): 30 June 2010

Introduction
The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to
cover all radio and telecommunications terminal equipment within the scope of the R&TTE Directive. The modular
structure is shown in EG 201 399 [8].

1 Scope
The present document applies to 5 GHz high performance wireless access systems (WAS) including RLAN equipment
which is used in wireless local area networks. Such networks provide high speed data communications in between
devices connected to the wireless infrastructure. The present document also applies to ad-hoc networking where these
devices communicate directly with each other, without the use of a wireless infrastructure. The equipment uses a
medium access protocol designed to facilitate spectrum sharing with other devices in the wireless network.
5 GHz high performance wireless access systems (WAS) including RLAN equipment covered by the present document,
and further referred to as RLAN devices, are operated in accordance with the ECC Decision (04)08 [5] and the
Commission Decision 2005/513/EC [6] as amended by the Commission Decision 2007/90/EC [7]. The equipment is
intended to operate in the frequency ranges 5 150 MHz to 5 350 MHz and 5 470 MHz to 5 725 MHz.
The present document is intended to cover the provisions of article 3.2 of R&TTE Directive [1], which states that:
"…radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio
communications and orbital resources so as to avoid harmful interference".

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in the R&TTE Directive [1] and the following
apply:
5 GHz RLAN bands: total frequency range that consists of 2 sub-bands:
• 5 150 MHz to 5 350 MHz; and

beam forming gain: additional (antenna) gain realized by using beam forming techniques in smart antenna systems
NOTE: Beam forming gain as used in the present document, does not include the gain of the antenna assembly.
burst: period during which radio waves are intentionally transmitted, preceded and succeeded by periods during which
no intentional transmission is made
channel: amount of spectrum used by a single RLAN device operating on one of the declared centre frequencies
channel plan: the combination of the centre frequencies and for each of the centre frequencies, the declared nominal
bandwidth(s)
combined equipment: any combination of non-radio equipment that requires a plug-in radio device to offer full

NOTE: An integral antenna may be fitted internally or externally. In the case where the antenna is external, a
non-detachable cable or wave-guide can be used.
master mode: mode which relates to the DFS functionality where the RLAN device uses a Radar Interference
Detection function and controls the transmissions of RLAN devices operating in slave mode
NOTE: In this mode it is able to select a channel and initiate a network by sending enabling signals to other
RLAN devices. A RLAN network always has at least one RLAN device operating in master mode when
operating in the bands 5 250 MHz to 5 350 MHz and 5 470 MHz to 5 725 MHz.
multi-radio equipment: radio, host or combined equipment using more than one radio transceiver
Operating Channel: Available Channel on which the RLAN has started transmissions
NOTE: An Operating Channel becomes again an Available Channel if the RLAN stopped all transmissions on
that channel and no radar signal was detected by the In-Service Monitoring.
plug-in radio device: radio equipment module intended to be used with or within host, combined or multi-radio
equipment, using their control functions and power supply
receive chain: receiver circuit with an associated antenna
NOTE: Two or more receive chains are combined in a smart antenna system.

RLAN device operating in master mode
NOTE: A RLAN device in slave mode may use a Radar Interference Detection function.
smart antenna systems: equipment that combines multiple transmit and/or receive chains with a signal processing
function to increase the throughput and/or to optimize its radiation and/or reception capabilities
NOTE: E.g. techniques such as spatial multiplexing, beam forming, cyclic delay diversity, MIMO, etc.
stand-alone radio equipment: equipment that is intended primarily as communications equipment and that is normally
used on a stand-alone basis
transmit chain: transmitter circuit with an associated antenna
NOTE: Two or more transmit chains are combined in a smart antenna system.
Transmit Power Control (TPC): technique in which the transmitter output power is controlled resulting in reduced
interference to other systems
Unavailable Channel: channel which can not be considered by the RLAN device for a certain period of time
(Non Occupancy Period) after a radar signal was detected on that channel
Unusable Channel: channel from the declared channel plan which may be declared as permanently unavailable due to
one or more radar detections on the channel
Usable Channel: any channel from the declared channel plan, which may be considered by the RLAN for possible use,
unless it is precluded by either:
1) the intended outdoor usage of the RLAN; or
2) previous detection of a radar on the channel (Unavailable Channel or Unusable Channel); or
3) national regulations; or
4) the restriction to only operate in the band 5 150 MHz to 5 250 MHz for RLAN devices without a radar
detection capability; or
5) being used by other RLAN devices.

Introduction The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to cover all radio and telecommunications terminal equipment within the scope of the R&TTE Directive. The modular structure is shown in EG 201 399 [8].
ETSI ETSI EN 301 893 V1.5.1 (2008-12) 7 1 Scope The present document applies to 5 GHz high performance wireless access systems (WAS) including RLAN equipment which is used in wireless local area networks. Such networks provide high speed data communications in between devices connected to the wireless infrastructure. The present document also applies to ad-hoc networking where these devices communicate directly with each other, without the use of a wireless infrastructure. The equipment uses a medium access protocol designed to facilitate spectrum sharing with other devices in the wireless network. 5 GHz high performance wireless access systems (WAS) including RLAN equipment covered by the present document, and further referred to as RLAN devices, are operated in accordance with the ECC Decision (04)08 [5] and the Commission Decision 2005/513/EC [6] as amended by the Commission Decision 2007/90/EC [7]. The equipment is intended to operate in the frequency ranges 5 150 MHz to 5 350 MHz and 5 470 MHz to 5 725 MHz.
The present document is intended to cover the provisions of article 3.2 of R&TTE Directive [1], which states that:
"…radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio communications and orbital resources so as to avoid harmful interference". 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • Non-specific reference may be made only to a complete document or a part thereof and only in the following cases: - if it is accepted that it will be possible to use all future changes of the referenced document for the purposes of the referring document; - for informative references.
