In order to ensure that radio equipment uses the radio spectrum effectively and supports the efficient use of radio spectrum, radio equipment should be constructed so that: in the case of a transmitter, when the transmitter is properly installed, maintained and used for its intended purpose it generates radio waves emissions that do not create harmful interference, while unwanted radio waves emissions generated by the transmitter (e.g. in adjacent channels) with a potential negative impact on the goals of radio spectrum policy should be limited to such a level that, according to the state of the art, harmful interference is avoided; and ...[+++], in the case of a receiver, it has a level of performance that allows it to operate as intended and protects it against the risk of harmful interference, in particular from shared or adjacent channels, and, in so doing, supports improvements in the efficient use of shared or adjacent channels.

The response curves of phase and amplitude against frequency are determined by measuring the output signals of the data channel in terms of phase and amplitude against a known input signal, for various values of this signal varying between FL and 10 times the CFC or 3 000 Hz, whichever is lower.

The work programme described includes - digital-signal processing (DSP), Reduced Instruction Set Computing (RISC), RF (radio frequency) communications, and touch-screen solutions - a focus on RF (radio frequency) semiconductor components for use in portable transmitters and receivers that operate at lower voltages and higher frequencies - systems architectures for wireline/wireless personal digital assistants (PDAs), personal intelligent communicators (PICs) and screenphone/fax.

To this end, it is asking the Twelve and by extension all the European bodies concerned, to reserve a specific frequency band of 169.4 to 169.8 MHz, which the European Conference of Postal and Telecommunications Administrations (CEPT) has said will be suitable. With the support of European firms, the administrations concerned in Europe also intend to adopt, through the CEPT, a new, worlwide standardized radiotaping code to permit faster and more extensive signalling, in particular including services (1) COM(89) 166 Putting an end to the fragmentation of the European market The ERMES system will end the fragmentation of the European marke ...[+++]t and help to bring down the cost of radiotaping receivers.
