<br />4. No land mobile radio user will be able to continue operating radios using 25 <br />kHz of bandwidth in the public safety service after December 31,2017. <br /> <br />{e <br /> <br />5. Licensees operating on 25 kHz of bandwidth are secondary to licensees <br />operating on 12.5 kHz channels. This means that any licensee on 25 kHz <br />that interferes with a licensee operating on 12.5 kHz must eliminate the <br />interference to the 12.5 kHz user. Any licensee on 25 kHz that is interfered <br />with by a 12.5 kHz licensee must accept the interference. <br /> <br />Likely Direction for Radio Manufacturers <br /> <br />1. land mobile radio manufacturers are likely to stop any further design work on <br />new radios capable of 25 kHz bandwidth as it will probably no longer be <br />possible to complete the basic design, complete testing and associated <br />design modifications, and then complete the FCC certification process before <br />December 31, 2004. In addition, the demand for analog modulation radios <br />capable of 25 kHz bandwidth is likely to drop rapidly as users are unlikely to <br />purchase new 25 kHz bandwidth radios due to the restrictions on new and <br />modified systems, and because new 25 kHz analog radios may not be at the <br />end of the useful life before they will need to be replaced by narrow band <br />radios. A further negative issue on design of new 25 kHz bandwidth radios is <br />that there is a limited manufacturing cycle available as the radios cannot be <br />sold after December 31,2007. <br /> <br />i. <br />, <br />\...-.' <br /> <br />2. land mobile radio manufacturers are likely to phase out production of <br />currently certified radios capable of 25 kHz bandwidth as demand drops. <br />Many existing radio designs are already near the end of the manufacturing <br />cycle and will be discontinued soon leaving an ever smaller set of radios for <br />users to choose between. <br /> <br />3. land mobile radio manufacturers will likely concentrate on the design and <br />manufacture of digital modulation radios because there may be little demand <br />for 12.5 kHz bandwidth analog modulation radios that have shorter range <br />than digital modulation radios. <br /> <br />land Mobile Radio User Impact <br /> <br />1. Any land mobile radio user in the Minneapolis-St.Paul region operating below <br />512 MHz that needs to add a channel to relieve congestion will probably need <br />to use 12.5 kHz bandwidth channels as there may not be many frequencies <br />resulting from turn backs from agencies migrating to 800 MHz before only <br />12.5 kHz radios are available. <br /> <br />2. There will be fewer and fewer analog radios available for purchase operating <br />on 25 kHz bandwidth, and there will be none after December 31, 2007. All 25 <br /> <br />. <br />
