952a4dc4fcb75b2b68ff94ff9bd171fe | 102 135 | 4 Executive summary | 4.1 Status of the System Reference Document The ERM TG32 DIIS working group has approved the present document. |
952a4dc4fcb75b2b68ff94ff9bd171fe | 102 135 | 4.2 Technical issues | DIIS is a new generation of digital PMR radio that is designed to operate within the existing channel rasters or spacing used in land mobile frequency bands in Europe. |
952a4dc4fcb75b2b68ff94ff9bd171fe | 102 135 | 4.2.1 Applications | DIIS is specifically targeted at small to medium sized PMR systems in all areas where analogue PMR is currently applied today. It will provide voice and data services. |
952a4dc4fcb75b2b68ff94ff9bd171fe | 102 135 | 4.2.1.1 Spectrum requirement and justifications | It is expected that DIIS will be implemented within the classic land mobile allocations by a natural re-farming process of old analogue PMR systems. However, the concerns about co-existence means that some defined parts of the PMR frequency bands need to be marked as preferential for DIIS protocol. A separate System Re... |
952a4dc4fcb75b2b68ff94ff9bd171fe | 102 135 | 4.2.2 Spectrum parameters | |
952a4dc4fcb75b2b68ff94ff9bd171fe | 102 135 | 4.2.2.1 Radiated power | DIIS radios will be operating with RF specifications broadly similar to those of current analogue PMR radios, i.e. 1 W to 5 W for handheld equipment and 5 W to 25 W for mobile and base station equipment. DIIS will also offer dynamic RF power control by the terminals. This will have the effect of increasing the frequenc... |
952a4dc4fcb75b2b68ff94ff9bd171fe | 102 135 | 4.2.2.2 Transmitted bandwidth | The transmitted bandwidth will comply with EN 300 113-1 [2] or EN 300 390-1 [4] as appropriate. ETSI ETSI TR 102 135 V1.1.1 (2002-12) 8 |
952a4dc4fcb75b2b68ff94ff9bd171fe | 102 135 | 4.2.2.3 Frequency considerations | Applicable frequencies will be the same as those currently used by analogue PMR radio systems and the 169,4 MHz to 169,8 MHz (ERMES) band would be an ideal candidate. The present document specifically applies to the ERMES band above and a separate document will cover DIIS deployment outside of the ERMES band. |
952a4dc4fcb75b2b68ff94ff9bd171fe | 102 135 | 4.2.3 Current regulations | For spectrum conformity testing the radio will comply with the current harmonized standard EN 300 113-2 [3] or EN 300 390-2 [5] as appropriate. |
952a4dc4fcb75b2b68ff94ff9bd171fe | 102 135 | 4.2.4 Compatibility issues | The primary co-existence issue to consider is that of allocation of shared frequencies between DIIS and analogue PMR users. Whilst DIIS radios will be able to co-exist within the framework of a defined "polite" channel access protocol, it is doubtful that all analogue radios will be able to distinguish between noise an... |
952a4dc4fcb75b2b68ff94ff9bd171fe | 102 135 | 5 Main conclusions | |
952a4dc4fcb75b2b68ff94ff9bd171fe | 102 135 | 5.1 Business importance | The transition to digital technology in all sectors of radio communications is vital in order to meet the user requirements whilst improving spectrum efficiency. To date the lower market sectors of PMR have not been addressed in ETSI standardization. The success of the DIIS protocol will be crucial to the future of the... |
952a4dc4fcb75b2b68ff94ff9bd171fe | 102 135 | 5.2 Expected timing for products to market | It is expected that the draft EN for the DIIS protocol will be completed by the end of 2002. It is estimated that commercial DIIS products would be available for first customer shipments within 24 months of the standard being published. |
952a4dc4fcb75b2b68ff94ff9bd171fe | 102 135 | 5.3 Requested ERC actions | This TG requests that ERC allocate this frequency band on a harmonized European wide basis to a digital speech and data service using a polite protocol. DIIS is an example of a suitable protocol. The frequency band covered by the present document covers the frequency range from 169,4 MHz to 169,8 MHz. This permits a to... |
