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 equipment within the scope of the Radio Equipment Directive (RED) [i.2].
It is recognized that the radio communications link alone does not determine the overall operation of a system, but that a
functioning radio communications link is an essential foundation upon which a system may be built.
ETSI
7 Final draft ETSI EN 303 406 V1.1.1 (2016-12)
The present document sets out various means and features by which the performance of a radio communications link
may be improved. These include:
1) Spectrum Access Rules - with the aim of reducing the probability of collisions between transmissions from
different equipment.
2) Receiver Parameters - with the aim of reducing the probability of interference from equipment on other
frequencies.
3) Bi-Directional Communications - with the aim of reducing the time and number of transmissions required to
achieve a given level of confidence in successful communication.
4) Frequency Agility - with the aim of enabling the equipment to change its operating frequency to avoid certain
types of interference.
Application of these features, separately or in combination, does not necessarily ensure successful radio
communication. In addition, there are other features that may be considered, such as listen before talk or error
correction, that may improve overall performance.
Clauses 1 and 3 provide a general description on the types of equipment covered by the present document and the
definitions and abbreviations used.
Clause 4 specifies technical requirements to be met by all equipment.
Clause 5 specifies technical requirements for receivers in equipment with uni-directional communications.
Clause 6 specifies technical requirements for equipment with bi-directional communications and frequency agility.
Clause 7 specifies the methods for testing for compliance with the technical requirements.
Annex A summarizes the requirements relevant to the RE-Directive [i.2].
ETSI
8 Final draft ETSI EN 303 406 V1.1.1 (2016-12)
1 Scope
The present document specifies technical characteristics and methods of measurements for social alarm systems
operating on a range of frequencies that may be shared with other equipment types.
Social alarms are defined in Commission Decision 2013/752/EU [i.3] as:
"Social alarm devices" are radio communications systems that allow reliable communication for a person in distress in
a confined area to initiate a call for assistance. Typical uses of social alarm are to assist elderly or disabled people.
These radio equipment types are capable of operating, for transmission or reception, in all or part of the frequency
bands given in table 1.
Table 1: Frequency bands and usage information
Frequency band Usage information
169,400 MHz to 169,8125 MHz This band is shared with other SRD equipment
868,600 MHz to 868,700 MHz This band is shared with other SRD alarm equipment
869,250 MHz to 869,400 MHz This band is shared with other SRD alarm equipment
869,650 MHz to 869,700 MHz This band is shared with other SRD alarm equipment
863,000 MHz to 870,000 MHz This band is shared with other SRD equipment,
except as noted above
870,000 MHz to 876,000 MHz This band is shared with other SRD equipment
915,000 MHz to 921,000 MHz This band is shared with other SRD equipment

NOTE 1: The probability of interference may be different when operating in bands shared with other short range
devices compared to bands from which other short range devices are excluded.
NOTE 2: Social alarms operating in a designated band are covered in ETSI EN 300 220-3-1 [i.5].
The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.2] under the
conditions identified in annex A.

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 equipment within the scope of the Radio Equipment Directive (RED) [i.2].
It is recognized that the radio communications link alone does not determine the overall operation of a system, but that a
functioning radio communications link is an essential foundation upon which a system may be built.
The present document sets out various means and features by which the performance of a radio communications link
may be improved. These include:
1) Spectrum Access Rules - with the aim of reducing the probability of collisions between transmissions from
different equipment.
2) Receiver Parameters - with the aim of reducing the probability of interference from equipment on other
frequencies.
3) Bi-Directional Communications - with the aim of reducing the time and number of transmissions required to
achieve a given level of confidence in successful communication.
4) Frequency Agility - with the aim of enabling the equipment to change its operating frequency to avoid certain
types of interference.
Application of these features, separately or in combination, does not necessarily ensure successful radio
communication. In addition, there are other features that may be considered, such as listen before talk or error
correction, that may improve overall performance.
Clauses 1 and 3 provide a general description on the types of equipment covered by the present document and the
definitions and abbreviations used.
Clause 4 specifies technical requirements to be met by all equipment.
Clause 5 specifies technical requirements for receivers in equipment with uni-directional communications.
Clause 6 specifies technical requirements for equipment with bi-directional communications and frequency agility.
Clause 7 specifies the methods for testing for compliance with the technical requirements.
Annex A summarizes the requirements relevant to the RE-Directive [i.2].

1 Scope
The present document specifies technical characteristics and methods of measurements for social alarm systems
operating on a range of frequencies that may be shared with other equipment types.
Social alarms are defined in Commission Decision 2013/752/EU [i.3] as:
"Social alarm devices" are radio communications systems that allow reliable communication for a person in distress in
a confined area to initiate a call for assistance. Typical uses of social alarm are to assist elderly or disabled people.
These radio equipment types are capable of operating, for transmission or reception, in all or part of the frequency
bands given in table 1.
Table 1: Frequency bands and usage information
Frequency band Usage information
169,400 MHz to 169,8125 MHz This band is shared with other SRD equipment
868,600 MHz to 868,700 MHz This band is shared with other SRD alarm equipment
869,250 MHz to 869,400 MHz This band is shared with other SRD alarm equipment
869,650 MHz to 869,700 MHz This band is shared with other SRD alarm equipment
863,000 MHz to 870,000 MHz This band is shared with other SRD equipment,
except as noted above
870,000 MHz to 876,000 MHz This band is shared with other SRD equipment
915,000 MHz to 921,000 MHz This band is shared with other SRD equipment

NOTE 1: The probability of interference may be different when operating in bands shared with other short range
devices compared to bands from which other short range devices are excluded.
NOTE 2: Social alarms operating in a designated band are covered in ETSI EN 300 220-3-1 [i.5].
The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.2] under the
conditions identified in annex A.

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 equipment within the scope of the Radio Equipment Directive (RED) [i.2].
It is recognized that the radio communications link alone does not determine the overall operation of a system, but that a
functioning radio communications link is an essential foundation upon which a system may be built.
The present document sets out various means and features by which the performance of a radio communications link
may be improved. These include:
1) Spectrum Access Rules - with the aim of reducing the probability of collisions between transmissions from
different equipment.
2) Receiver Parameters - with the aim of reducing the probability of interference from equipment on other
frequencies.
3) Bi-Directional Communications - with the aim of reducing the time and number of transmissions required to
achieve a given level of confidence in successful communication.
4) Frequency Agility - with the aim of enabling the equipment to change its operating frequency to avoid certain
types of interference.
Application of these features, separately or in combination, does not necessarily ensure successful radio
communication. In addition, there are other features that may be considered, such as listen before talk or error
correction, that may improve overall performance.
Clauses 1 and 3 provide a general description on the types of equipment covered by the present document and the
definitions and abbreviations used.
Clause 4 specifies technical requirements to be met by all equipment.
Clause 5 specifies technical requirements for receivers in equipment with uni-directional communications.
Clause 6 specifies technical requirements for equipment with bi-directional communications and frequency agility.
Clause 7 specifies the methods for testing for compliance with the technical requirements.
Annex A summarizes the requirements relevant to the RE-Directive [i.2].

1 Scope
The present document specifies technical characteristics and methods of measurements for social alarm systems
operating on a range of frequencies that may be shared with other equipment types.
Social alarms are defined in Commission Decision 2013/752/EU [i.3] as:
"Social alarm devices" are radio communications systems that allow reliable communication for a person in distress in
a confined area to initiate a call for assistance. Typical uses of social alarm are to assist elderly or disabled people.
These radio equipment types are capable of operating, for transmission or reception, in all or part of the frequency
bands given in table 1.
Table 1: Frequency bands and usage information
Frequency band Usage information
169,400 MHz to 169,8125 MHz This band is shared with other SRD equipment
868,600 MHz to 868,700 MHz This band is shared with other SRD alarm equipment
869,250 MHz to 869,400 MHz This band is shared with other SRD alarm equipment
869,650 MHz to 869,700 MHz This band is shared with other SRD alarm equipment
863,000 MHz to 870,000 MHz This band is shared with other SRD equipment,
except as noted above
870,000 MHz to 876,000 MHz This band is shared with other SRD equipment
915,000 MHz to 921,000 MHz This band is shared with other SRD equipment

NOTE 1: The probability of interference may be different when operating in bands shared with other short range
devices compared to bands from which other short range devices are excluded.
NOTE 2: Social alarms operating in a designated band are covered in ETSI EN 300 220-3-1 [i.5].
The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.2] under the
conditions identified in annex A.
