SIST EN 302 502 V1.1.1:2006 is the Slovenian adoption of ETSI EN 302 502 V1.1.1, a harmonized European standard for Broadband Radio Access Networks (BRAN). It applies to 5.8 GHz fixed broadband data transmitting systems and specifies the radio spectrum, emission and DFS requirements used to show conformity with Article 3.2 of the R&TTE Directive. Manufacturers, test laboratories and conformity assessors use it to verify channel plans, power levels, unwanted emissions and radar-avoidance behaviour.
What does SIST EN 302 502 V1.1.1:2006 specify?
SIST EN 302 502 V1.1.1:2006 applies to radio equipment for Fixed Broadband Data Transmitting Systems operating in the 5.8 GHz band, and it covers equipment with integral or dedicated antennas. The document is written to support presumption of conformity with the essential radio requirement in Article 3.2 of the R&TTE Directive.
The standard is organized into a short front matter, then five main clauses:
- Clause 1 Scope
- Clause 2 References
- Clause 3 Definitions, symbols and abbreviations
- Clause 4 Technical requirements specification
- Clause 5 Testing for compliance with technical requirements
It is followed by five annexes.
| Annex | What it covers |
|---|---|
| Annex A | HS Requirements and conformance Test specifications table (HS-RTT) |
| Annex B | Test sites and arrangements for radiated measurements |
| Annex C | General description of measurement |
| Annex D | DFS parameters |
| Annex E | EN title in the official languages |
What are the key requirements of SIST EN 302 502 V1.1.1:2006?
Frequency plan and frequency accuracy
SIST EN 302 502 V1.1.1:2006 requires the manufacturer to declare the centre frequencies on which the equipment can operate, and the equipment shall only use channels centred on those declared frequencies. The actual carrier centre frequency must stay close to the nominal channel centre frequency.
In practice, this is the basic channel-planning rule for the product. It tells the designer and buyer which channel widths are supported and ensures the transmitter stays on the intended channel.
Output power, EIRP and spectral density
SIST EN 302 502 V1.1.1:2006 sets separate limits for mean RF output power, Equivalent Isotropically Radiated Power (EIRP) and EIRP spectral density at the highest stated power setting. The limits depend on the declared channel width, with separate cases for 10 MHz and 20 MHz channels.
In practice, the antenna gain and transmitter power have to be considered together. A product can only be assessed correctly if the declared antenna assemblies, power settings and channel width match the configuration tested.
Unwanted emissions and idle or standby behaviour
SIST EN 302 502 V1.1.1:2006 requires transmitter unwanted emissions to stay within the limits outside the 5.8 GHz operating band, and it also defines an emission mask inside the band. If the equipment has an idle or standby mode in addition to transmit mode, that mode must meet the receiver spurious emission requirements.
In practice, this is the filter and leakage control part of the standard. It matters because it limits how much the equipment can disturb adjacent spectrum users and how much noise it can emit when it is not actively transmitting.
Transmit Power Control (TPC)
SIST EN 302 502 V1.1.1:2006 requires the equipment to support Transmit Power Control (TPC), so that the operating mean EIRP can be reduced from the highest level. The standard ties this to spectrum sharing, especially where many devices operate in the same band.
In practice, TPC is a feature that helps reduce interference without changing the channel plan. A buyer or integrator should check that the product can lower its power as claimed, not only operate at maximum power.
Receiver spurious emissions
SIST EN 302 502 V1.1.1:2006 limits spurious emissions from the receiver while the equipment is in receive mode. The requirement covers a broad frequency range and is verified by conducted or radiated testing, depending on the antenna arrangement.
In practice, this is about preventing the receiver electronics from becoming an unintended transmitter. It matters for coexistence testing and for systems with sensitive co-located radio functions.
Dynamic Frequency Selection (DFS)
SIST EN 302 502 V1.1.1:2006 requires full Dynamic Frequency Selection (DFS) for devices in a Fixed Wireless Access (FWA) deployment. The equipment must detect radar signals, check channels before use, monitor the operating channel during service, shut down the channel after radar detection, and keep the channel unused for the required non-occupancy period before revalidation.
In practice, DFS is the main coexistence feature of the standard. Annex D fixes the DFS timing parameters, interference threshold, and the radar test signals used to prove that the equipment detects radar reliably enough and moves away quickly enough.
Test conditions, antenna arrangements and measurement quality
SIST EN 302 502 V1.1.1:2006 specifies how testing is to be done. It defines the environmental profile, the test transmission sequences, the test frequencies, how to present equipment with integral or dedicated antennas, and how to handle host-connected or plug-in radio devices.
In practice, this keeps laboratory results comparable. The standard also requires measurement uncertainty to be reported and applied with a shared-risk approach, so the test report has to show how close the measured values are to the limit.
What terms does SIST EN 302 502 V1.1.1:2006 define?
- Antenna assembly - The antenna, its coaxial cable, and any connector or switching parts are treated as one assessed set.
- Available channel - A channel that has been checked and can be used for transmission.
- Operating channel - An available channel that the device is currently using for transmission.
- Fixed Wireless Access (FWA) - The deployment context for these systems, where fixed radio links provide broadband access.
- Transmit Power Control (TPC) - A technique for lowering transmitter output power to reduce interference.
- Dynamic Frequency Selection (DFS) - The mechanism used to detect radar and avoid channels that are in use.
- Unit Under Test (UUT) - The device, or device combination, that is being measured in the compliance test.
Who uses SIST EN 302 502 V1.1.1:2006?
SIST EN 302 502 V1.1.1:2006 is used by manufacturers of 5.8 GHz fixed broadband data transmitting systems, including equipment with integral antennas and equipment with external or dedicated antennas. It is also used by antenna suppliers, module makers, test laboratories, certification bodies, and compliance or quality teams.
Typical tasks include declaring supported channel widths and centre frequencies, defining antenna gains, setting transmit power and TPC ranges, running DFS tests, and preparing technical files for conformity assessment. Buyers and system integrators use it to check that a product is aligned with the regulatory and test expectations for the band.
Which standards are used with SIST EN 302 502 V1.1.1:2006?
- Directive 1999/5/EC [1] - The legal framework behind the essential requirement on efficient spectrum use and harmful interference avoidance.
- ETSI EN 300 019-1-0 [2] - Used for guidance when declaring the environmental profile for testing.

4.6 Dynamic Frequency Selection (DFS)
4.6.1 Introduction
All devices in a FWA deployment shall employ full Dynamic Frequency Selection (DFS) functionality to detect
transmissions from other systems and to avoid co-channel operation with these systems, notably radar systems.
Radar detection (DFS) is not required in the frequency range 5 850 MHz to 5 875 MHz.
The operational behaviour and DFS requirements for all equipment are as follows:
a) the equipment shall use a Radar Interference Detection function in order to detect radar signals;
b) before transmitting on a channel, which has not been identified as an Available Channel, the equipment shall
perform a Channel Availability Check (see clause 4.6.2.1) to ensure that there is no radar operating on the
channel;
c) during normal operation, the equipment shall monitor the Operating Channel (In-Service Monitoring) to ensure
that there is no radar operating on the channel;
d) if the equipment has detected a radar signal during In-Service Monitoring, the Channel Shutdown shall be
initiated and the Operating Channel becomes an Unavailable Channel;
e) the equipment shall not resume any transmissions on this Unavailable Channel during a period of time after a
radar signal was detected. This period is referred to as the Non-Occupancy Period (see clause 4.6.2.4);
f) after the end of a Non-Occupancy Period, a Channel Availability Check is required before an Unavailable
Channel can be identified as an Available Channel again;
g) a channel can only have one status at any specific time.
