Introduction
Private Wide-Area Paging (PWAP) systems are basically On-Site Paging (OSP) systems with an
extended range achieved by using a higher transmitter power (for guidance 25W could be a suitable
value) and antenna location, as well as a specified receiver sensitivity. These systems can use time
sharing in order to increase the number of virtual available channels. The time sharing as specified in
part 2 of this ETS is a free running system that requires minimum overhead and supplies minimum loss of
net-air time.
Potential applications include emergency services, hospitals and manufacturing industry that may be
located at various sites within the covered area.
This ETS is based mainly on ETS 300 224, ETS 300 133 part 5, ESPA publication 4.2.7.
In preparing this ETS, much attention has been given to assure a low interference probability, while at the
same time allowing a maximum flexibility and service to the end-user.
The conditions for licensing as well as conditions for interfacing to the Public Switched Telephone Network
(PSTN) are determined by the appropriate authorities.
Additional standards or specifications may be required for equipment intended to interface to the Public
Switched Telephone Network.

manufacturer shall provide for the power source circuit feeding the crystal oven to be independent of the
power source to the rest of the equipment.
a) Procedure for equipment designed for continuous operation:
If the manufacturer states that the equipment is designed for continuous operation, the test procedure
shall be as follows:
- before tests at the upper temperature, the equipment shall be placed in the test chamber and left
until thermal balance is attained. The equipment shall then be switched on in the transmit condition
for a period of half an hour, after which the equipment shall meet the specified requirements. For
tests at the lower temperatures, the equipment shall be left in the test chamber until thermal
balance is attained, after which the equipment shall meet the specified requirements.
b) Procedure for equipment designed for intermittent operation:
If the applicant states that the equipment is designed for intermittent operation, the test procedure shall be
as follows:
- before tests at the upper extreme temperature are made, the equipment shall be placed in the test
chamber and left until thermal balance is attained;
the equipment shall then either:
- transmit "on" and "off", according to the duty cycle as declared by the applicant, for a period
of five minutes; or
- if the "on" period as declared by the applicant exceeds one minute, transmit in the "on"
condition for a period not exceeding one minute, followed by a period in the "off" or "standby"
mode for four minutes, after which the equipment shall meet the specified requirements.
Page 14
ETS 300 719-1: July 1997
For tests at the lower extreme temperature the equipment shall be left in the test chamber until thermal
balance is attained, then the equipment shall be switched to the "standby" or "receive" condition for one
minute, after which the equipment shall meet the specified requirements.
5.3.2 Extreme temperature limits
For tests at extreme temperatures, measurements shall be made in accordance with procedures specified
in subclause 5.3.1 over the following ambient temperature range:
- base station equipment: -20°C to +55°C;
- pocket receiver equipment: -10°C to +55°C.
5.3.3 Extreme test power source
The power source voltage for tests under extreme voltage conditions shall be as follows:
a) the extreme source voltages for equipment to be connected to an ac mains source shall be the
nominal mains voltage ±10 %;
b) when the equipment is intended for operation from the usual types of battery power sources, the
extreme voltages shall be as follows:
- where the equipment has a battery status indicator, the extreme voltages shall be the end
point voltages indicated by the battery status indicator of the equipment under test;
- where the equipment does not have a battery status indicator, and the manufacturer has not
declared the end point voltages, the following end point voltages shall be used:
1) Leclanché type of battery or Lithium type of battery:
- 0,85 multiplied by the nominal voltage of the battery;
2) Nickel-metal hydride or Nickel cadmium type of battery:
- 0,9 multiplied by the nominal voltage of the battery;
No upper extreme test voltages apply for 1) and 2).
3) Equipment using other power sources:
- for equipment using other power sources, or capable of being operated from a
variety of power sources, the extreme test voltages shall be those agreed
between the equipment manufacturer and the testing authority and shall be
recorded in the test report.
5.3.4 Test power source
During type tests the power source of the equipment shall be replaced by a test power source, capable of
producing normal and extreme test voltages as specified in subclauses 5.2.2 and 5.3.3. The internal
impedance of the test power source shall be low enough to ensure that its effect on the test results is
negligible. For the purpose of tests, the voltage of the power source shall be measured at the input
terminals of the equipment.
If power to the equipment is provided from an external power source, the test voltages shall be those
measured at the point of connection of the power cable to the equipment.
In battery operated equipment, the test power source shall be applied as close to the equipment battery
supply terminals as practicable.
Page 15
ETS 300 719-1: July 1997
During the tests the test power source voltages shall be maintained within a tolerance of 1 % relative to
the voltage at the beginning of each test.
6 Electrical test conditions
6.1 Normal test signals and test modulation
The test modulation signal is a baseband signal which modulates a carrier and is dependent upon the type
of equipment under test and also the measurement to be performed.
6.1.1 Normal test signals for data
These test signals are defined as:
- D-M1: a test signal that produces the "space" (0) or "mark" (1) condition continuously;
- D-M2: a test signal that produces an alternating series of "space" (0) or "mark" (1) at the highest
transmission rate;
- D-M3: a test paging signal shall be agreed between the test laboratory and the manufacturer in
cases when selective messages are used and are generated or decoded within the
equipment. The agreed test signal shall comprise a selective address and (depending
upon pager type) a message consisting of 10 numeric characters or 20 alpha-numeric
characters. The signal may be formatted and may contain error detection and correction.
The normal level of the test signal D-M3 shall produce a deviation of 20 % of the channel spacing or any
other value as declared by the manufacturer as the normal operating level.
For test purposes if special equipment is required to generate the test signal D-M3 or to indicate the
correct acceptance of the messages, it shall be supplied by the manufacturer.
6.2 Artificial load
Tests on the transmitters shall be carried out with a 50 Ω non-reactive non-radiating load, connected to
the antenna terminal or test fixture terminal. The Voltage Standing Wave Ratio (VSWR) of the artificial
load shall not exceed 1:1,2 over the frequency range of the measurements.
6.3 Test fixture for pocket receivers with an integral antenna
With equipment intended for use with an integral antenna, and not equipped with a 50 Ω output
connection, the manufacturer may be required to supply a test fixture. This test fixture is a radio frequency
coupling device for coupling the integral antenna to a 50 Ω radio frequency terminal at the working
frequencies of the equipment under test. This allows certain measurements to be performed using
conducted measuring methods. Only relative measurements may be performed using the test fixture.
If applicable the test fixture shall provide means to supply power to the pocket receivers under test.
The performance characteristics of the test fixture shall be agreed upon with the test laboratory and shall
conform to the following basic parameters:
- the circuitry associated with the Radio Frequency (RF) coupling shall contain no active or non-linear
devices;
- the coupling loss shall not influence the measuring results;
- the coupling loss shall be independent of the position of the test fixture and be unaffected by the
proximity of surrounding objects or people;
- the coupling loss shall be reproducible when the equipment under test is removed and replaced;
- the coupling loss shall remain substantially constant when the environmental conditions are varied.

6.4 Test site and general arrangements for the measurement of radiated fields
Test sites shall be open air. The term "open air" should be understood from an electromagnetic point of
view. Such a test site may be "outdoor" (really in open air) or alternatively "indoor" with walls and ceiling
transparent to the radio waves at the frequencies considered. For these purposes, an anechoic room is
considered "open air".
For guidance on test sites see ETR 027 [1], the relevant part of which is reproduced in annex A.
6.5 Arrangements for test signals applied to the base station receiver input
Sources of test signals for application to the receiver input shall be connected through a network such that
the impedance presented to the receiver input is 50 Ω.
This requirement shall be met irrespective of whether one or more signals are applied to the receiver
simultaneously.
The levels of the test signals shall be expressed in terms of electromotive force (emf) at the output
terminals of the network prior to connection to the receiver input terminals.
The effects of any intermodulation products and noise produced in the signal generators should be
negligible.
7 Base station transmitter requirements
In case of equipment with variable output power, all measurements shall be made using the highest rated
power level. The equipment shall also be adjusted to the lowest rated output power setting and the
measurements in the following subclauses shall be repeated: subclaus

Introduction
Private Wide-Area Paging (PWAP) systems are basically On-Site Paging (OSP) systems with an
extended range achieved by using a higher transmitter power (for guidance 25W could be a suitable
value) and antenna location, as well as a specified receiver sensitivity. These systems can use time
sharing in order to increase the number of virtual available channels. The time sharing as specified in
part 2 of this ETS is a free running system that requires minimum overhead and supplies minimum loss of
net-air time.
Potential applications include emergency services, hospitals and manufacturing industry that may be
located at various sites within the covered area.
This ETS is based mainly on ETS 300 224, ETS 300 133 part 5, ESPA publication 4.2.7.
In preparing this ETS, much attention has been given to assure a low interference probability, while at the
same time allowing a maximum flexibility and service to the end-user.
The conditions for licensing as well as conditions for interfacing to the Public Switched Telephone Network
(PSTN) are determined by the appropriate authorities.
Additional standards or specifications may be required for equipment intended to interface to the Public
Switched Telephone Network.

For operation from other power sources or types of battery (primary or secondary), the normal test voltage
shall be that declared by the equipment manufacturer. Such values shall be stated in the test report.
In pocket equipment with integral antenna, the battery shall not be replaced with an external power source
when making radiating measurements, because this external power source could influence the test
results.
5.3 Extreme test conditions
5.3.1 Procedure for tests at extreme temperatures
Before measurements are made the equipment shall have reached thermal balance in the test chamber.
The equipment shall be switched to standby during the temperature stabilizing period.
In the case of equipment containing stabilization circuits designed to operate continuously, the
temperature stabilization arrangements shall be switched on for 15 minutes after thermal balance has
been obtained, and the equipment shall then meet the specified requirements. For such equipment the
manufacturer shall provide for the power source circuit feeding the crystal oven to be independent of the
power source to the rest of the equipment.
a) Procedure for equipment designed for continuous operation:
If the manufacturer states that the equipment is designed for continuous operation, the test procedure
shall be as follows:
- before tests at the upper temperature, the equipment shall be placed in the test chamber and left
until thermal balance is attained. The equipment shall then be switched on in the transmit condition
for a period of half an hour, after which the equipment shall meet the specified requirements. For
tests at the lower temperatures, the equipment shall be left in the test chamber until thermal
balance is attained, after which the equipment shall meet the specified requirements.
b) Procedure for equipment designed for intermittent operation:
If the applicant states that the equipment is designed for intermittent operation, the test procedure shall be
as follows:
- before tests at the upper extreme temperature are made, the equipment shall be placed in the test
chamber and left until thermal balance is attained;
the equipment shall then either:
- transmit "on" and "off", according to the duty cycle as declared by the applicant, for a period
of five minutes; or
- if the "on" period as declared by the applicant exceeds one minute, transmit in the "on"
condition for a period not exceeding one minute, followed by a period in the "off" or "standby"
mode for four minutes, after which the equipment shall meet the specified requirements.
Page 14
ETS 300 719-1: July 1997
For tests at the lower extreme temperature the equipment shall be left in the test chamber until thermal
balance is attained, then the equipment shall be switched to the "standby" or "receive" condition for one
minute, after which the equipment shall meet the specified requirements.
5.3.2 Extreme temperature limits
For tests at extreme temperatures, measurements shall be made in accordance with procedures specified
in subclause 5.3.1 over the following ambient temperature range:
- base station equipment: -20°C to +55°C;
- pocket receiver equipment: -10°C to +55°C.
5.3.3 Extreme test power source
The power source voltage for tests under extreme voltage conditions shall be as follows:
a) the extreme source voltages for equipment to be connected to an ac mains source shall be the
nominal mains voltage ±10 %;
b) when the equipment is intended for operation from the usual types of battery power sources, the
extreme voltages shall be as follows:
- where the equipment has a battery status indicator, the extreme voltages shall be the end
point voltages indicated by the battery status indicator of the equipment under test;
- where the equipment does not have a battery status indicator, and the manufacturer has not
declared the end point voltages, the following end point voltages shall be used:
1) Leclanché type of battery or Lithium type of battery:
- 0,85 multiplied by the nominal voltage of the battery;
2) Nickel-metal hydride or Nickel cadmium type of battery:
- 0,9 multiplied by the nominal voltage of the battery;
No upper extreme test voltages apply for 1) and 2).
3) Equipment using other power sources:
- for equipment using other power sources, or capable of being operated from a
variety of power sources, the extreme test voltages shall be those agreed
between the equipment manufacturer and the testing authority and shall be
recorded in the test report.
5.3.4 Test power source
During type tests the power source of the equipment shall be replaced by a test power source, capable of
producing normal and extreme test voltages as specified in subclauses 5.2.2 and 5.3.3. The internal
impedance of the test power source shall be low enough to ensure that its effect on the test results is
negligible. For the purpose of tests, the voltage of the power source shall be measured at the input
terminals of the equipment.
If power to the equipment is provided from an external power source, the test voltages shall be those
measured at the point of connection of the power cable to the equipment.
In battery operated equipment, the test power source shall be applied as close to the equipment battery
supply terminals as practicable.
Page 15
ETS 300 719-1: July 1997
During the tests the test power source voltages shall be maintained within a tolerance of 1 % relative to
the voltage at the beginning of each test.

These test signals are defined as:
- D-M1: a test signal that produces the "space" (0) or "mark" (1) condition continuously;
- D-M2: a test signal that produces an alternating series of "space" (0) or "mark" (1) at the highest
transmission rate;
- D-M3: a test paging signal shall be agreed between the test laboratory and the manufacturer in
cases when selective messages are used and are generated or decoded within the
equipment. The agreed test signal shall comprise a selective address and (depending
upon pager type) a message consisting of 10 numeric characters or 20 alpha-numeric
characters. The signal may be formatted and may contain error detection and correction.
The normal level of the test signal D-M3 shall produce a deviation of 20 % of the channel spacing or any
other value as declared by the manufacturer as the normal operating level.
For test purposes if special equipment is required to generate the test signal D-M3 or to indicate the
correct acceptance of the messages, it shall be supplied by the manufacturer.
6.2 Artificial load
Tests on the transmitters shall be carried out with a 50 Ω non-reactive non-radiating load, connected to
the antenna terminal or test fixture terminal. The Voltage Standing Wave Ratio (VSWR) of the artificial
load shall not exceed 1:1,2 over the frequency range of the measurements.
6.3 Test fixture for pocket receivers with an integral antenna
With equipment intended for use with an integral antenna, and not equipped with a 50 Ω output
connection, the manufacturer may be required to supply a test fixture. This test fixture is a radio frequency
coupling device for coupling the integral antenna to a 50 Ω radio frequency terminal at the working
frequencies of the equipment under test. This allows certain measurements to be performed using
conducted measuring methods. Only relative measurements may be performed using the test fixture.
If applicable the test fixture shall provide means to supply power to the pocket receivers under test.
The performance characteristics of the test fixture shall be agreed upon with the test laboratory and shall
conform to the following basic parameters:
- the circuitry associated with the Radio Frequency (RF) coupling shall contain no active or non-linear
devices;
- the coupling loss shall not influence the measuring results;
- the coupling loss shall be independent of the position of the test fixture and be unaffected by the
proximity of surrounding objects or people;
- the coupling loss shall be reproducible when the equipment under test is removed and replaced;
- the coupling loss shall remain substantially constant when the environmental conditions are varied.

6.4 Test site and general arrangements for the measurement of radiated fields
Test sites shall be open air. The term "open air" should be understood from an electromagnetic point of
view. Such a test site may be "outdoor" (really in open air) or alternatively "indoor" with walls and ceiling
transparent to the radio waves at the frequencies considered. For these purposes, an anechoic room is
considered "open air".
For guidance on test sites see ETR 027 [1], the relevant part of which is reproduced in annex A.
6.5 Arrangements for test signals applied to the base station receiver input
Sources of test signals for application to the receiver input shall be connected through a network such that
the impedance presented to the receiver input is 50 Ω.
This requirement shall be met irrespective of whether one or more signals are applied to the receiver
simultaneously.
The levels of the test signals shall be expressed in terms of electromotive force (emf) at the output
terminals of the network prior to connection to the receiver input terminals.
The effects of any intermodulation products and noise produced in the signal generators should be
negligible.
7 Base station transmitter requirements
In case of equipment with variable output power, all measurements shall be made using the highest rated
power level. The equipment shall also be adjusted to the lowest rated output power setting and the
measurements in the following subclauses shall be repeated: subclause 7.2 (carrier power)
