Top grade wireless networks comprises of various access points and antennas in strategic locations to optimize signal integrity and simultaneously minimizing cost and increasing economic efficiency. One must interconnect these access points and antennas for proper magnification of signal strength. However, one must wonder, how and what type of connections must exist in the network.

Reverse SMA
Antennas and access points are normally connected using a reverse SMA connection. A reverse SMA cable is a SMA cable with reversed polarity, meaning the pin is in the female instead of the male connector.

SMA (SubMiniature version A) are coaxial RF connectors developed in the 1960's. It looks similar to RCA and BNC connectors. The connector has a screw type coupling mechanism, which easily and quickly attaches and reattaches while maintaining connection integrity, forming a durable and dependable connection between connectors. The connector has a 50 Ω impedance and has top-of-the-line high performance statistics for electrical conductivity from DC to 18 GHz. -- ideal for wireless networking that must function with mission critical reliability.

TNC
Linksys and Cisco products may use TNC instead of SMA connectivity.

TNC (Threaded Neill Concelman) is a threaded version of the BNC connector developed in late 1950's and named after Amphenol engineer Carl Concelman. The connector has a screw type coupling mechanism, which easily and quickly attaches and reattaches while maintaining connection integrity, forming a durable and dependable connection between connectors. The connector has a 75 Ω impedance with excellent electrical operation from 0 to 11 GHz. The threaded coupling interface ensures connection integrity in vibration-intensive applications, offering premium performance and dependability under high-stress conditions.
