RGV:299:5/31/00 <br /> ANALYSIS OF ANOKA COUNTY LAW ENFORCEMENT RADIO <br /> QUESTIONNAIRE RETURNS <br /> CRITICAL CONCERNS <br /> 1. Congestion is a major problem, the main dispatch channel is oversaturated <br /> during busier periods. There are fewer reports of car stops and fewer <br /> reports of out -of -car during busier months with safety concerns as a result. <br /> There are also fewer reports to dispatch of on- the -scene during busier <br /> periods which is an operational problem for dispatch operators. <br /> 2. Coverage is less than desirable which is rated a critical problem. Fifteen of <br /> 17 rated communications with dispatch using a portable radio inside as a <br /> critical need, but there are widespread reports of poor in- building coverage. <br /> Poor outdoor coverage is reported in the Bethel, East Bethel and Linwood <br /> areas and generally in the northeast part of the county. <br /> 3. The potential for a single point failure causing loss of the radio system for up <br /> to three or more hours is rated critical by 13 while four rated this as a major <br /> concern. <br /> 4 Interference is mentioned as a critical problem on Channel 2 by nine of 15 <br /> (60 %). Interference covering or garbling transmission - seven yes and three <br /> at times. Interference causes confusion — seven yes, one at times and one <br /> no. Interference causes less effectiveness or efficiency — ten yes and one at <br /> times. <br /> 5. The potential jamming of the main dispatch channel is rated a critical concern <br /> by 15 respondents while two rated potential jamming as a very important <br /> concern. <br /> 6. Monitoring of law enforcement radio channels by criminals is rated a critical <br /> problem by 15 while two rated this as a very important concern. A number of <br /> respondents indicated that use of Mobile Data Communications was a way to <br /> relieve this problem for persons in vehicles. <br />
