What do we think, when talking about wireless network?Antenna
Band
Frequency
Bandwidth
Interference
Signal to Noise Ratio (SNR)
Client Connection Quality (CCQ)
Multiple Input Multiple Output (MIMO)
Spatial Stream (SS)
Modulation and Coding Scheme (MCS)
Noise Floor Signal
Protocol
Polarization
Hardware-protection (CTS/RTS)
Service Set Identifier (SSID)
Transmission power
Signal Strength
Wireless security (WEP,WPA,WPA2)
Wireless Distribution System (WDS)
Mesh
Good wireless network? High signal strength?
High transmission power?
High gain antenna?
