Introduction
Overview
Integrating the cutting edge of Internet Telephony and VoIP Router manufacturing experience, PLANET
now introduces the latest member of PLANET Wireless VoIP Router family: the VIP-281SW.
The VIP-281SW provides not only high-quality voice communications and wired Internet sharing
capabilities but also the Access Point (AP) function for flexible wireless communication. With advanced
router and VoIP DSP processor technology, the VIP-281SW is able to make calls via SIP proxy voice
communications plus the IP sharing and the QoS mechanism.
By applying the VIP-281SW, home users and companies are able to save installation cost and extend
the VoIP network from their previous investments in telephones, conferences and speakerphones. The
VIP-281SW is equipped with two telephony interfaces, so users may register to different SIP proxy
servers and establish up to 2 concurrent VoIP calls for more flexibility in the voice communications. The
VIP-281SW can also be the bridge between traditional analog telephones and IP network with an
extremely affordable investment.
With built-in IEEE 802.11b/g/n wireless network capability, the VIP-281SW allows any computer and
wireless enabled network client connect to it without additional cabling. The 802.11n wireless
capability gives users the highest speed of wireless experience ever. With an 802.11n compatible
wireless adapter installed in your PC, the files can be transferred at up to 300Mbps. The radio coverage
is also doubled to offer the high speed wireless connection even in a wide space of your office or house.
To secure the wireless communication, the VIP-281SW supports most up-to-date encryption: WEP,
WPA-PSK and WPA2-PSK. In addition, the VIP-281SW supports WPS configuration with PBC/PIN
type for users to connect to a secured wireless network easily.
