INTRODUCTION
AirEZY-2411-BT is an 802.11b compliant, or WiFi, radio with a 10-BaseT
interface.
Two features separate AirEZY-2411-BT from many other 802.11b-compliant
radios. Firstly, this 802.11b-compliant (WiFi) radio can be configured as
either a Station (ACR-201) or an AP (ASR-102). Secondly, when configured as
a Station, the 10-BaseT interface affords it a true plug-and-play feature that is
unavailable from any other 802.11b Station radios are based on either a PCMCIA
or a USB interface and require the installation of a driver on the host computer.
This driver-less feature also means that the operation of the radio is OS
(operating system) independent.
When configured as a Station, i.e. ACR-201, the driver-less feature enables
wireless connectivity for any computing devices/systems installed with any OS
(operating system), as long as an Ethernet communication port is available.
Ethernet-equipped workstations in a corporate environment, for example, benefit
greatly from this driver-less feature—the IT workforce has one less driver to
worry when upgrading an OS or when salvaging an OS crash. Special
computing/networking devices, such as printer servers, POS (point of sales)
machines may not even have an easy way of installing a driver for a radio.
When configured as an AP, i.e., ASR-102, AirEZY-2411-BT, offers a no-frill,
seamless way of fitting a wireless network into an existing wired LAN
infrastructure. It does not even require the assignment of an extra IP address.
Existing wired-network resources such as DHCP, VPN, firewall, etc., reach
across the ASR-102 to the client workstations with total transparency. Unlike
many other 802.11b APs on the market, which offer network functions that are
duplicative to the existing network, this AP simply wirelessly collects a group of
workstations or other kinds of computing devices into the existing network—just
like a hub.
AirEZY-2411-BT has a compact form-factor that blends easily into a home/office
environment. It also lends particularly well to portable applications. The
specifications are given on the next page.
A Utility program is needed to pre-configure AirEZY-2411-BT prior to putting the
radio in operation. And the Utility program can be used to monitor the
communication condition once the radio is in operation. Once configured, the
radio runs self-sufficiently without the aid of any driver program in the host
computer connected to the radio. This Utility program therefore is intended to be,
in most cases, just a tool for the network operators. An end user simply plugs the
pre-configured radio into a host computer or a network device equipped with a
RJ-45 receptacle without ever being expose to this Utility program. The Utility
program is simple to install and easy to use through its graphic user interface.
The details are described in Chapter 3.
