Security is an important element of data transmission, irrespective of the network topology. It is especially important for military and corporate applications. Building a network on the SONAbeam platform is one of the best ways to ensure that data transmission between any two points is completely secure. Its focused transmission beam foils jammers and eavesdroppers and enhances security. Moreover, fSONA systems can use any signal-scrambling technology that optical fiber can use.

The common perception of wireless is that it offers less security than wireline connections. In fact, FSO is far more secure than RF or other wireless-based transmission technologies for several reasons:

• Laser beams cannot be detected with spectrum analyzers or RF meters
• Laser transmissions travel along a line of sight path that cannot be intercepted easily. It requires a matching transceiver carefully aligned to complete the transmission. Interception is very difficult and extremely unlikely
• The laser beams are narrow and invisible, making them harder to find and even harder to intercept and crack
• Data can be transmitted over an encrypted connection adding to the degree of security available in FSO network transmissions.
