Radio Characteristics
Radio Characteristics of the MPCI3A-20/R WIRELESS LAN CARD may vary:
• According to the country where the product was purchased.
• According to the type of product that was purchased.

Wireless communication is often subject to local radio regulations. Although the
MPCI3A-20/R WIRELESS LAN CARD has been designed for operation in the
license-free 2.4 GHz band, local radio regulations may impose a number of
limitations to the use of wireless communication equipment.
To comply with such regulations, MPCI3A-20/R WIRELESS LAN CARD is marketed
with dedicated channel-sets with a number of factory-programmed channels
identified by the following acronyms:
• ETS for countries that adhere to the regulations as defined by the European
Telecommunications Standards Institute (ETSI),
• FCC for countries that adhere to the regulations as defined by the US Federal
Communications Commission (FCC),
• FR for France, and
• JP for Japan.
