IP phones and Analog Terminal Adapters (ATAs) require a network connection. LAN cabling in the office or the home can be expensive to install if not already wired. Wi-Fi networks are practically everywhere today. Poly USB Wi-Fi adapter enables USB-equipped VoIP adapters or VVX phones (models with USB ports) to connect to the Internet over a Wi-Fi network. With the Poly Wi-Fi adapter, you have the freedom to place your VVX phones or VoIP adapters anywhere within range of your Wi-Fi network. Deployment tip - if you are using the WiFi adapter to connect your phone or VoIP adapter, these devices are typically powered by Power over Ethernet (PoE). So, if you are not plugging into a wired LAN with PoE and are instead using the USB Wi-Fi accessory, don't forget to also order the appropriate power adapter to power your phone or VoIP device.
