Redwood City Police <br /> Department System Performance <br /> l 0%to 50% System easily accommodates the data <br /> � load. <br /> SO%to 75% The system will support peaks in data <br /> , traffic without appreciable degradation ia <br /> response time. . <br /> 75% to 100% With this amount of usage, data backlog <br /> caused by message traffic peaks should <br /> clear quite quickly. The users may notice <br /> a longer response time for a short period <br /> � while the system reiluns to no�al. As <br /> the utilization increases toward the upper <br /> limit of this range, data.backlog caused <br /> by traffic peaks will take longer to clear <br /> and system response times will increase. <br /> 100% + System becomes unstable and easily <br /> saturates. <br /> The results of the loading calculations show that to implement <br /> reports and AVL will require: One 19.2 kbps channel is sufficient <br /> `. for the projected load including reports�and AVL and up to 200 <br /> units. <br /> RADIO INFRASTRUCTURE COVERAGE <br /> Motorola has designed the radio infrastructure segment of this <br /> Mobile Data System to meet the needs of the City of Hillsborough, <br /> the City of Foster City, and the City of Redwood City Police <br /> Departments. Radio coverage maps included in this proposal show <br /> anticipated coverage from the following site: <br /> � Proposed Site Latitude Longitude <br /> Cross 37�27'22" 122� 16' 08'" <br /> Mazlborough 37� 32' 44" 122�21' 40" <br /> The predicted mobile area coverage is based on the analysis results <br /> obtained using Motorola's MOZAI&SM coverage prediction <br /> � ,_ <br /> prograin. The MOZAIKSM prograin computes predicted coverage <br /> �MOroEro�..4 3 - 14 <br /> , <br /> . _ ___ _ <br />
