Ad Hoc And Infrastructure
If you are using an “Infrastructure” network – one in which WORK-
ABOUT PROs must pass data through an access point – leave the checkbox
next to
‘This is an ad hoc network’
blank.
If you are using an “Ad Hoc” network – a network in which hand-held com-
puters pass data directly to other hand-helds without an access point – tap
on the checkbox next to
‘This is an ad hoc network’
to enable (
√
) Ad Hoc.
Encryption
WEP (Wired-Equivalent Privacy) encryption prevents others from acciden-
tally accessing your network. If you are not using encryption, you can
choose ‘Disabled’ from the dropdown encryption menu. Otherwise, leave
this field as is.
Authentication
802.11b supports two subtypes of network authentication services:
Open
and
Shared
. Under
Open
authentication, any wireless station can request
authentication. The station that needs to authenticate with another wireless
station sends an authentication management frame that contains the identity
of the sending station. The receiving station then sends back a frame that
indicates whether it recognizes the identity of the sending station.
Under
Shared
authentication, each wireless station is assumed to have
received a secret shared key over a secure channel that is independent from
the 802.11b wireless network communications channel.
Network Key:
This text box is used to specify a 5 or 13 ASCII character sequence or an
equivalent 10 or 26 Hexadecimal digit sequence that matches the active
WEP key on the access point.
