9.13 Security

Today, the operation and management of an enterprise is becoming
increasing dependent on electronic information flow. An accompanying
concern becomes the security of the communication infrastructure and the
security of the data itself. GE MDS takes this matter seriously, and provides
several means for protecting the data carried over its wireless products.
The radio addresses this issue primarily through the use of the following
items:
1. A proprietary modem/data link layer—Data signals are processed
using code and hardware specifically designed by GE MDS.
2. A unique Network Address—This provides a unique identifier for each
radio in a network. A radio is not addressable unless this unique code is
included in the data string.
3. An optional encryption value (code)—Setting an encryption code
requires the use of the
radio's hop pattern and encrypts payload data content. A radio requires
the correct Network Address (
