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

1. A proprietary modem/data link layer—Data signals are processed

included in the data string.
3. An optional encryption value (code)—Setting an encryption code

radio's hop pattern and encrypts payload data content. A radio requires
the correct Network Address (
