• Question 258:

  Basic requirements for WLAN network construction include bandwidth requirements, coverage targets, coverage methods, field strength requirements, and power distribution methods. Determining the strength of the coverage area in the field strength requirement is adjusted by the AP transmit power. The following statements are correct regarding the requirements that the network regulation needs to consider in advance.Is it?

  A. The field strength demand in key areas is that the main online area of the user can be controlled at -40~-80dBm. If the power is too strong, it will easily lead to receiving overload, and the power is too weak.Will cause the connection rate to drop
