Market research, which includes social and opinion research, is the systematic gathering and interpretation of information about individuals or organizations using statistical and analytical methods and techniques of the applied social sciences to gain insight or support decision making.
Each access point has limits for the number of connections and amount of network load it can handle, but by integrating multiple of them into a larger network, the overall scale can be increased. Many individual wireless routers and other access points support up to approximately 250 connected devices. Routers can accommodate a small number (usually between one and four) of wired Ethernet clients with the rest connected over wireless.
Different wireless clients negotiate different link speeds with the wireless router, based on the wireless modes, distance, and noise level (the level of interference from other wireless transmissions). To get IEEE 802.11n speed, both the wireless router and wireless client have to support 11n mode. If either the wireless router or the wireless client can support only 11a or 11g, the link rate would be a maximum of 54 Mbps, and the actual data transfer speed would be about 22 Mbps. The most common 11n maximum link rates are 150 Mbps and 300 Mbps.
