Setup
Note: This document refers to “ clicking ” or “ tapping ” interchangeably, although the physical action is
actually a tapping of the stylus on the YES tablet 7370 touchscreen.
Wireless Access Points
The YES
tablet is normally used as a wireless workstation. For wireless operation, there must be
802.11b access points available to provide the connection between YES tablets and the local Ethernet
network. Specific access point configuration depends upon the vendor and model, but here are some
general guidelines.
Identification
All points in an 802.11b wireless network share a unique name called a Service Set ID (SSID) or an
Extended Service Set ID (ESSID). In this document, the two terms will be used interchangeably. This
name is specified in each access point, and is configured in the YES
tablet in one of two ways.
•
Broadcast . An access point can be configured to broadcast its SSID. Under the zero
configuration design of the wireless 802.11b LAN support under CE.net, the YES tablet 7370 will
detect all broadcasted SSIDs within its range. You can then select the desired access point for your
connection.
•
Non-Broadcast . For security purposes, an access point may be configured to disable SSID
broadcasts. In this case, the SSID must be manually entered into the YES tablet ’s wireless adaptor
card configuration parameters. Note that SSIDs are case-sensitive.
Security
In addition to SSIDs, two more-sophisticated security methods are available:
Wired Equivalent Privacy (WEP)
WEP is a data privacy mechanism based on 64-bit or 128-bit encryption. To use WEP encryption, all
points in the wireless network must enable WEP and have the same 40-bit or 104-bit key setting. WEP
is disabled as default on the YES
tablet .
Extensible Authentication Protocol (EAP)
The new standard for wireless LAN security, as defined by the Institute of Electrical and Electronics
Engineers (IEEE), is called
802.1X for 802.11 , or simply 802.1X . An access point that supports 802.1X
