Anleitung Zusammenfassung
Important: Wireless coverage should be ubiquitous throughout the workspace. If legacy devices are in use, both Wi-Fi bands, 802.11b/g/n 2.4 GHz and 802.11a/n/ac 5 GHz should be central to the design plan. Design for coverage The physical layout of the building may have an impact on your Wi-Fi network design. For example, in a small business environment, users may meet with other employees in conference rooms or in offices. As a result, users move around the building throughout the day. In this scenario, the majority of network access comes from low bandwidth activities such as checking mail, calendars, and Internet browsing, so Wi-Fi coverage is the highest priority. A Wi-Fi design could include a small number of points on each floor to provide coverage for the offices. Additional access points might be considered for areas where large numbers of employees gather, such as a large conference room. Design for density Contrast the scenario above with a school that has 1000 students and 30 teachers in a two-story building. Every student is issued an iPad, and every teacher is issued both a MacBook Air and an iPad. Each classroom holds approximately 35 students, and classrooms are next to each other. Throughout the day, students conduct research on the Internet, watch curriculum videos, and copy files to and from a file server on the Local Area Network (LAN). The Wi-Fi network design for high density is more complex, due to the higher density of mobile devices. Because of the large number of students in each classroom, one access point per classroom might be required. Multiple access points should be considered for the common areas, to provide adequate coverage and bandwidth. The number of access points for the common areas may vary, depending on the density of Wi-Fi devices in those spaces. Important: A pre-install site survey should always be performed to determine the exact number of access points needed and where those access points should be mounted. A site survey also determines the proper power settings for each radio. Once the installation of the Wi-Fi network is complete, a post-install site survey should be performed to confirm the Wi-Fi environment. Sometimes it is desirable to create multiple SSIDs for different purposes. For example, a guest network may be required. Care should be taken to avoid creating too many SSIDs, as the additional SSIDs cause additional bandwidth usage. Design for Applications Apple products use multicast networking for services like AirPlay and AirPrint. Therefore, multicast support should be part of the design plan.
