We’re clearly living in the golden age of wireless technologies – a time when we are expecting almost any device and function to be wire-free. One obvious advantage of wireless functionality is that it simplifies the process of connectivity and extends the connectivity range for greater flexibility. Another, perhaps even more important benefit to most clients, is that it eliminates the ugly, tangled mess that cables invariably cause.
But wireless technologies can be frustrating and confusing if they are not designed and implemented well. This article from Infocomm International shares some valuable advice on how you can get wireless working well in your AV project.
Some of the insightful suggestions in it are:
“…Wi-Fi bands often are crowded, especially the 2.4 GHz band. “If there’s a lot of traffic on the 2.4 GHz network, you’re probably going to want to look at the 5 GHz network…”
“(for security)… If AV will piggyback on an existing WLAN, then work with the client’s IT staff to partition the AV portion as a virtual LAN (VLAN), which helps eliminate the back doors.”
“Look for wireless microphone systems that support a wide swath of spectrum, for two reasons. First, it enables the system to scale up gracefully as a facility grows. Second, more spectrum means more opportunities to work around interference.”
“One best practice is to reduce the distance between the antenna and the devices it serves. Doing so maximizes a signal’s strength and thus its ability to carry as much video and other content as possible.”
“Although Wi-Fi is widely used in pro AV, it has enough drawbacks — particularly its crowded spectrum even at 5 GHz — that some AV and IT vendors have developed alternatives, such as WiDi, WiGig, WHDI, and WirelessHD.”
