The present document applies to 5 GHz high performance 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 RLAN equipment covered by the present document is operated in accordance with the ECC Decision (04)08 [5] and the Commission Decision 2005/513/EC [6]. 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 radiocommunications and orbital resources so as to avoid harmful interference".

ETSI
9 ETSI EN 301 893 V1.4.1 (2007-07)

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.

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

(Non-Occupancy Period) after a radar signal was detected on that channel
Usable Channel: any channel from the declared channel plan, which can 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
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.

4 Technical requirements specifications
4.1 Environmental profile
The technical requirements of the present document apply under the environmental profile for operation of the
equipment, which shall be stated by the manufacturer.
The equipment shall comply in any of the operating modes with all the technical requirements of the present document
at all times when operating within the boundary limits of the stated operational environmental profile.
4.2 Centre frequencies
4.2.1 Definition
The centre frequency is the centre of the channel declared by the manufacturer as part of the declared channel plan(s).
4.2.2 Limits
The actual centre frequency for any given channel declared by the manufacturer shall be maintained within the range
f ± 20 ppm.
c
4.2.3 Conformance
Conformance tests as defined in clause 5.3.2 shall be carried out.
4.3 Nominal Channel Bandwidth and Occupied Channel
Bandwidth
4.3.1 Definition
The nominal channel bandwidth is the widest band of frequencies, inclusive of guard bands, assigned to a single
channel.
The occupied channel bandwidth is the frequency bandwidth of the signal power at the -6 dBc points when measured
with a 100 kHz resolution bandwidth.
NOTE: dBc is the spectral density relative to the maximum spectral power density of the transmitted signal.
4.3.2 Limits
The nominal bandwidth shall be in the range from 10 MHz to 40 MHz.
The occupied channel bandwidth shall be between 80 % and 100 % of the declared nominal channel bandwidth. In case
of smart antenna systems (devices with multiple transmit chains) each of the transmit chains shall meet this
requirement.
NOTE: The limit for occupied bandwidth is not applicable for devices with a nominal bandwidth of 40 MHz
when temporarily operating in a mode in which they transmit only in the upper or lower 20 MHz part of a
40 MHz channel. (e.g. to transmit a packet in the upper or lower 20 MHz part of a 40 MHz channel).
4.3.3 Conformance
Conformance tests as defined in clause 5.3.3 shall be carried out to determine the occupied channel bandwidth.

4.4 RF output power, Transmit Power Control (TPC) and power
density
4.4.1 Definitions
4.4.1.1 RF output power
The RF output power is the mean equivalent isotropically radiated power (EIRP) during a transmission burst.
4.4.1.2 Transmit Power Control (TPC)
Transmit Power Control (TPC) is a mechanism to be used by the UUT to ensure a mitigation factor of at least 3 dB on
the aggregate power from a large number of devices. This requires the UUT to have a TPC range from which the lowest
value is at least 6 dB below the values for mean EIRP given in table 1.
TPC is not required for channels whose nominal bandwidth falls completely within the band 5 150 MHz to 5 250 MHz.
4.4.1.3 Power density
The power density is the mean Equivalent Isotropically Radiated Power (EIRP) density during a transmission burst.
4.4.2 Limits
The limits below are applicable to the system as a whole and in any possible configuration. This includes smart antenna
systems (devices with multiple transmit chains).
4.4.2.1 RF output power and power density at the highest power level
For devices with TPC, the RF output power and the power density when configured to operate at the highest stated
power level of the TPC range shall not exceed the levels given in table 1.
For devices without TPC, the limits in table 1 shall be reduced by 3 dB, except when operating on channels whose
nominal bandwidth falls completely within the band 5 150 MHz to 5 250 MHz.
