<br />, I, <br /> <br />RGV:299:5/31/00 <br /> <br />ANALYSIS OF ANOKA COUNTY LAW ENFORCEMENT RADIO <br />QUESTIONNAIRE RETURNS <br /> <br />CRITICAL CONCERNS <br /> <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 /> <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 /> <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 /> <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 /> <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 /> <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 />
