6.1 Introduction to Wi-Fi
Wi-Fi, a popular name for 802.11b, refers to the underlying technology for wireless local
area networks (WLAN) based on the IEEE 802.11 suite of specifications conforming to
standards defined by IEEE. IEEE 802.11b describes the media access and link layer con-
trol for a 2.4 GHz implementation, which can communicate at a top bit-rate of 11 Mbits/s.
Other standards describe a faster implementation (54 Mbits/s) in the 2.4 GHz (802.11g)
and a 54 Mbits/s implementation in the 5.6 GHz band (802.11a). The adoption of 802.11
has been fast because it's easy to use and the performance is comparable to wire-based
LANs. Things look pretty much like a wireless LAN.
Wi-Fi (802.11b) is the most common and cost-effective implementation currently avail-
able. This is the implementation that is used with the RCM4400W RabbitCore module. A
variety of Wi-Fi hardware exists, from wireless access points (WAPs), various Wi-Fi
access devices with PCI, PCMCIA, CompactFlash, USB and SD/MMC interfaces, and
Wi-Fi devices such as Web-based cameras and print servers.
802.11b can operate in one of two modes—in a managed-access mode (BSS), called an
infrastructure mode, or an unmanaged mode (IBSS), called the ad-hoc mode. The 802.11
standard describes the details of how devices access each other in either of these modes.
6.1.1 Infrastructure Mode
The infrastructure mode requires an access point to manage devices that want to communi-
cate with each other. An access point is identified with a channel and service set identifier
(SSID) that it uses to communicate. Typically, an access point also acts as a gateway to a
wired network, either an Ethernet or WAN (DSL/cable modem). Most access points can
also act as a DHCP server, and provide IP, DNS, and gateway functions.
When a device wants to join an access point, it will typically scan each channel and look
for a desired SSID for the access point. An empty-string SSID (" ") will associate the
device with the first SSID that matches its capabilities.
Once the access point is discovered, the device will logically join the access point and
announce itself. Once joined, the device can transmit and receive data packets much like
an Ethernet-based MAC. Being in a joined state is akin to having link status in a
10/100Base-T network.
