authentication in a wireless LAN. Smart cards also provide an easy way for users
to carry an authentication device with them. On a smart card users can store
important information, such as security keys and network profiles. The smart
card reader reads the data stored on the computer chip and sends it to the network
for processing. The smart card is protected by a PIN code; to access the contents of
the smart card, you need to enter the correct PIN code.
Warning:
Keep all miniature smart cards out of small children’s reach.
Antennas
The Nokia C110/C111 Wireless LAN Card is equipped with two internal antennas
placed inside an extension box providing improved signal quality and coverage
area. As with any other radio transmitting device, do not touch the antenna
unnecessarily when the wireless LAN card is in use. Contact with the antenna
affects the quality of the transmission and may cause the wireless LAN card to
operate at a higher power level than otherwise needed.
Note:
Make sure that the antenna is pointing towards the access point and
placed in an open area. Do not cover the antenna.
The Nokia C111 has two antenna connectors for attaching external antennas for
coverage area extension. The Nokia C111 can be used with up to two external
antennas at the same time. Use only the supplied antennas or an approved external
antenna. Unauthorized antennas, modifications, or attachments could damage
the wireless LAN card and may violate regulations governing radio devices.
If only one external antenna is used, best performance is obtained by connecting
the external antenna to the right antenna connector of the wireless LAN card.
