Deploy a Wireless Access PointIn order to prevent common faults, you should master some simple basic precautions. In order to ensure that the wireless access point is deployed without any problems, This article summarizes the ten experiences gained from practice.
1. The location of the wireless access point should not be near the metal structure.
When deploying wireless access points, you must note that the actual location of the deployment should not
according to 2 a latitude and longitude point, calculate this 2 distance between a latitude and longitude pointThe formula for calculating the distance between any two points on a sphere can be found in the following articles on Wikipedia.
Great-circle distance
Haversine formula
It is worth mentioning that Wikipedia recommends the use of the Haversine formula, the reason is that the great-circle distance formula uses a large number o
It's just a second answer, and then consider how to validate.Meet the Bi−ai≤mid b_i-a_i \le mid point on the tube, set the transmission point built in X,y X,y, the remaining points need to meet:| x−ai|+| Y−bi|≤mid | x-a_i|+| Y-b_i|\le midThis is difficult to do if we find that we consider enumerating an endpoint. Can be transformed, note that the constraint above is a form of a Manhattan distance, that is to say (X,y) (X,y), (Ai,aj) (A_i,a_j) as a poi
