Overview of ETSI EN 300 220-3-1 Testing

ETSI EN 300 220-3-1 testing covers short range devices operating in the frequency range from 25 MHz to 1,000 MHz. This wireless test standard covers low duty cycle high reliability equipment. It also covers social alarms and equipment operating on designated frequencies.

The standard defines what a low duty cycle / high reliability device is. These devices rely on low overall spectrum utilization. They also rely on low duty cycle spectrum access rules to ensure high reliable spectrum access and transmissions in shared bands.

The specific equipment that falls under ETSI EN 300 220-3-1 compliance testing is typically alarm systems that use radio communication for indicating an alert condition at a distant location. Also, social alarm systems that allow reliable communication for a person in distress fall under this standard.

The ETSI EN 300 220-3-1 radio test standard recognizes that the radio communications link alone does not determine the overall operation of a system. However, a functioning radio communications link is an essential foundation upon which a system may be built.

Objectives of the Testing

There are three objectives of improving the performance of a radio communications link. The first is a set of spectrum access rules. The objective is to reduce the probability of collisions between transmissions from different equipment.

The second objective is receiving parameters. The goal is to reduce the probability of interference of equipment on other frequencies. The third objective is bi-directional communication. This aims at reducing the number of transmissions needed to achieve a given level of confidence in successful communication.

It is important to note that completion of these three tasks does not in and of itself ensure successful radio communication. Other features may impact communication. These include error correction and Listen Before Talk.

What Are Frequency Errors?

A common question that arises from wireless radio testing is frequency error. These are the differences between the measured and unmodulated carrier frequency and the nominal operating frequency. These can occur under extreme and normal conditions.

Frequency errors are normally measured with an unmodulated carrier. This requirement does not apply if the equipment is incapable of producing an unmodulated carrier. In these occasions, the adjacent channel power requirements shall be met under extreme test conditions.

The ETSI EN 300 220-3-1 radio test standard has seven clauses. Clauses one, two and three provide general details such as the scope, references and definitions. Clause four defines the technical requirements that all equipment must meet.

 Clauses five and six specify technical requirements. Clause five is written for receivers in equipment with uni-directional communications. Equipment with bi-directional communications are detailed in clause six. Clause seven details the testing method for compliance and the technical requirements.

Testing Parameters of ETSI EN 300 220-3-1

To declare compliance to the technical requirements, the ETSI EN 300 220-3-1 test lab must address the following parameters. The operating frequency, normal operating voltage and minimum operating voltage must be declared. So must the test modes, antenna gain and the antenna type and connection.

Other parameters include channel width, duty cycle, environmental profile and maximum duty cycle. The declaration of conformity test sample must be provided. The mod A or b1 operation must also be declared.
