Choosing the Right Wireless Headset System For Your Office Phone
What about call security?
For most wireless headset users Call Security is a non-issue. For some sectors, government and military, or defense however, the issue of security is incredibly important.
In a wireless headset system, there is ample opportunity for the signal to be snooped by an eavesdropper, and different wireless headsets offer different types of protection against this.
- Channel Hopping - The frequency that the two parts of the headset system talk on, is changed very rapidly.
- Encryption The signal between the headset and the base unit is digitally encrypted
- Range Restrictions The signal is never sent further than necessary range is controlled through intelligent power management in the base station
Of these three strategies it is Digital Encryption that offers the greatest protection, with Channel Hopping and Range Restrictions adding an extra layer of obscurity and decreased opportunity respectively. Its widely believed that the GN Netcom GN 9120 Digital Headset offers the greatest security available at the time of writing employing all three strategies. It channel hops a staggering 90 times a second and intelligently manages the power of the signal it produces to make sure that it is never broadcast further than range.
The Plantronics CS range of headsets (CS55, CS55 Micro, CS351, and CS70N) all employ digital encryption strategies, and further Plantronics will produce systems to custom specifications for those organizations where security at any cost is an issue.
