If you do the work and wire the 2nd transmission point you will be much more satisfied with the end result. Examples: Heavy Walls, Vertical Differential (transmitter upstairs and downstairs low signal or vise versa) Noise is caused because of other equipment generating competing RF signal (AC or Furnace, Microwaves, larger powered electrical motor, or poorly shielded one) Most of which can be solved by relocating the transmission point or adding a WIRED secondary transmission point (effectively creating a second route that doesn't need to travel through the point creating the RF noise) My experience if the 2nd transmission point isn't wired it will be a dismal disappointment. Most newer chipsets use 0 to 100.įrom my experience signal strength is reduced because of barriers between the transmission point and receiving point. Notes: Look at the RSSI only on an associated client Some older chipsets used RSSI from 0 to 256, or 0 to 127. A higher difference of signal to noise indicates better signal. To get a meaniful measurement of a good quality signal, you would have to subtract the noise on the line from that signal power level and consider the difference.
As a general example, a good signal would be -50, a reasonable would be -75, and a bad one would be -90, while -100 would provide no service at all. For example, RSSI of -65 is better than -85. The closer the figure is to zero, the better. It is often expressed in decibels (db), or as percentage values between 1-100, and can be either a negative, or a positive value. RSSI is the relative signal strength in a wireless environment and can be measured in any unit of power. It is a measure of the power level that a RF client device is receiving from an access point, for example. RSSI (Recieved Signal Strength Indicator) is a common name for the signal strength in a wireless network environment.
