MU-MIMO uses multiple antennas to form separate data streams for multiple devices at the same time. The access point can beamform to several clients simultaneously, so each device receives its own stream rather than waiting for a turn. This boosts overall network capacity and reduces wait time, especially in busy environments, because throughput isn’t spent on serving one client at a time. This isn’t about stronger encryption, and it doesn’t remove the need for an access point. It also isn’t about one device using multiple channels—that’s a different technique like channel bonding. MU-MIMO specifically enables concurrent downlink transmissions to several clients using distinct spatial streams.

Disabling WPS centers on reducing a security risk. WPS was meant to make it easier to connect devices, but it has vulnerabilities that can let an attacker bypass normal authentication and join the network. The WPS PIN feature, in particular, can be brute-forced more easily than standard WPA2/WPA3 connections, giving an intruder access without knowing your actual passphrase. By turning WPS off, you remove that attack path, improving overall security. WPS does not affect speed, and it isn’t required for WPA3—WPA3 uses its own secure setup SAMPLEmethods. WPS also isn’t limited to 5 GHz; it can be present on both bands, so disabling it eliminates a potential weak link across the network.

The most fundamental factor is understanding what kind of facility you will be surveying. The facility type sets the context for every design decision in a WLAN site survey. Different buildings have very different RF environments: construction materials (concrete, metal, glass), ceiling heights, room layouts, and occupancy patterns all influence how signals propagate and where you should place access points. For example, a multi-story hospital with many dense spaces has distinct coverage and security requirements compared to an open-plan office or a warehouse. Knowing the facility type helps you anticipate interference sources, determine the number and placement of APs, set realistic coverage and capacity targets, and plan Maverick measurements like signal strength, interference, and roaming behavior accordingly. It also helps you gauge user needs and use cases, such as which areas must be covered reliably, what kinds of devices will be used, and how many concurrent users you expect in peak times. This context guides the survey scope, measurement plan, and success criteria, ensuring the results produce a usable, efficient wireless network tailored to the environment. Timing, address details, and vendor preferences matter too, but they are logistical or implementation choices rather than the information that shapes the network design from the ground up. Knowing the facility type first informs what areas to survey, what environmental factors to measure, and what performance targets to set.

Private IPv4 addresses are reserved for use inside local networks and are not routable on the public Internet. They let LANs assign addresses without consuming public space, often behind a NAT device that translates to a public address when accessing the Internet. The standard private blocks are 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. Together they cover large, commonly used address ranges for internal networks: - 10.0.0.0/8 spans from 10.0.0.0 to 10.255.255.255 - 172.16.0.0/12 spans from 172.16.0.0 to 172.31.255.255 - 192.168.0.0/16 spans from 192.168.0.0 to 192.168.255.255 The best option lists all three canonical private blocks, which is why it’s the correct choice. Other options either include a non-private range (such as 172.32.0.0/12) or specify only a subset of a private block (like 192.168.1.0/24) rather than the full private ranges used in LANs.
