Những lý do chính là tốc độ triển khai, | Designing a Wireless Enterprise Network Hospital Case Study Chapter 9 305 Project 1 Providing Satellite Building Access When designing a wireless network in an enterprise building you must determine the placement of antennas and access points for best coverage. In this example the mechanical room elevators and communications room are sources of frequency interference that you need to consider. A single omnidirectional antenna might be capable of covering the office area in a satellite building over 100 feet . However with the interference items to consider it would be better to place omnidirectional antennas and access points in each hallway as shown in the Figure to get better coverage. Also each access point can provide redundancy. If one access point fails the other provides access to all computers on the floor. The access point wireless bridges will be placed on shelves near the antennas. The Ethernet ports of the access point bridges will be connected to the LAN switches that serve the floor. The LAN switch must be configured to permit multiple media access control MAC addresses on the data port. Designing Planning. Other Antenna and Access Point Bridge Placements There are several methods of placing antennas to have full coverage in a floor. Directional antennas could be placed in each of the four corners of the floor aiming at a 45-degree angle toward the center of the building. To verify antenna placement place an access point bridge at each location and test its range with a laptop with a wireless card. It is helpful to perform this test using a roll cart so you can roll around the hallways offices and conference rooms to verify coverage. Project 2 Providing Wireless Technology to the Conference Rooms For the conference room project plan to install one access point wireless bridge. Users requiring wireless LAN connectivity will need to install wireless LAN network interface cards into their laptop computers. The access point will be configured as a .
