Building a Cisco Wireless LAN

The following examples of both interior and exterior wireless designs will help guide you through some of the more common wireless implementations.
The example in Figure 4.19 shows a design for a warehouse in which wireless coverage is the maximum concern for the customer. Automatic rate negotiation will be used because coverage is the primary concern and cabling is available to all points in the store. The warehouse has a very high ceiling and the visibility of antennas to the customers is not of concern; therefore, we chose a high-gain, mast-mount antenna for the maximum coverage.
Here in Figure 4.20 is the same warehouse as described in the previous section, but instead of using the high-gain, omni-directional antenna, we used the patch antennas and one rubber dipole to provide coverage for the facility. With this design, we were able to get identical coverage using different types of antennas but with two less APs.
One possible reason to use the patch antennas could be that cabling for wired Ethernet is not available in the middle of the warehouse and is available only around the edges of the facility. Therefore, the patch antennas in the warehouse would increase coverage from the perimeter .
Figure 4.21 depicts the same warehouse except in this situation Ethernet wiring is available only in the front of the...
