Wireless Topologies

Harmony wireless products look and operate similar to Ethernet products. The only difference is that a radio replaces the wire between various nodes. This means that all of your existing applications that operate over Ethernet will work with Harmony without any special wireless networking software. The Harmony 802.11a network adapters support several network topologies, which are described in this chapter.

Ad Hoc

Two or more computers easily establish an ad hoc network when the units are in range of each other. Each computer can dynamically connect and reconnect to the others with no additional configuration, using off-the-shelf peer-to-peer network operating systems, as illustrated in Figure 1.

Figure 1 Ad Hoc

To use a Harmony 802.11a network adapter as a member of an Ad Hoc network with other 802.11a-compatible cards, configure the adapter to operate in Ad Hoc mode. See “Network Mode” on page 28 for details.

Note: Products sold in Europe do not support Ad Hoc mode.
