Wireless Information

Ad Hoc And Infrastructure: If you are using an Infrastructure network – one in which

NEOs 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 NEOs pass data directly to
other Ad Hoc devices without an access point – add a checkmark in 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.
AES (Advanced Encryption Standard) is a standard for protecting data through encryp-
tion. AES supports key sizes of 128 bits, 192 bits and 256 bits and will serve as a
replacement for the Data Encryption Standard (DES), which has a key size of 56 bits. In
addition to the increased security that comes with larger key sizes, the AES algorithm is
a symmetric block cipher that can encrypt (encipher) and decrypt (decipher)
information.

Authentication: 802.11 supports four subtypes of network authentication services:

Open, Shared, WPA, and WPA-PSK. 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.

Important: Keep in mind that NEO will only communicate with access points that are

configured with the same SSID.
