If any of the cells has an anticipated number of portables percell that is more than 44 or 23, repeat step 4.If you have too many portables in an area, inform your customer.Note 1: If the -45 dBm contour lines overlap, users may hear long mutes,voice interruptions, crackling speech, or they may drop calls.Note 2: You do not need to verify that the offices and office areas in a highportable density system are at -70 dBm or better because all linkswill be greater than -70 dBm.Example of a high portable density areaChildren’s Hospital wants to provide a wireless system for its nurses. It wantsto provide up to 200 portables to be covered anywhere on the floor. The salesgroup recommends the Meridian Companion system.You survey the site as if it is an area that is not high portable density and findthat the site can be covered with three cells, as shown in Figure 29.Figure 29 : Example of standard cell planningNone of the 200 users have an office on the floor, so you compute theanticipated portable count to be 67 (200 ÷ 3) users for each cell. Using Table 8on page 38, you find that the anticipated number of portables per cell countexceeds 23, therefore you must plan the floor for high portable density.cell center-73 dBm contour1C31C31C31C11C11C21C23
