To provide the highest level of security to wireless data transmitted via your
wireless network, you can use the Wired Equivalent Privacy (WEP) data
encryption.
To use WEP data encryption in your network, you need:
— All wireless stations and access points must be equipped with CP
1515 cards
— All devices must be configured with matching WEP encryption key
values.
WEP data encryption uses 13-character encryption keys, based on the RC4
encryption algorithm, that will be used to encrypt/decrypt all data
transmitted via the wireless interface.
You can specify up to 4 different keys to

decrypt

wireless data, and select
one of the specified decryption key values to

encrypt

wireless data.
The option to use 4 different keys for decrypting wireless data, allows you to
change your WEP keys at regular intervals without affecting regular network
performance (see also Maintaining WEP Encryption Keys (page 183)).
