Overview

The NetLink e340/h340/i640 Wireless Telephone is a mobile handset for workplace IP telephone systems. NetLink Wireless Telephones operate over an 802.11b wireless Ethernet LAN providing users a wireless voice over IP (VoIP) extension. By seamlessly integrating with the Mitel IP telephony system, NetLink Wireless Telephone users are provided with high-quality mobile voice communications throughout the workplace. The NetLink Wireless Telephone gives users the freedom to roam throughout the workplace while providing all the features and functionality of an IP desk phone.

The NetLink e340/h340/i640 Wireless Telephone provides a wireless extension to the Mitel Networks 3300 and SX-200 ICP VoIP solutions. The NetLink Wireless Telephone supports the MiNET protocol, a proprietary protocol developed by Mitel Networks for communication between a Mitel Networks IP phone and a Mitel Networks PBX.

The NetLink Wireless Telephones reside on the wireless LAN with other wireless devices using Direct Sequence Spread Spectrum (DSSS) radio technology. The handset radio transmits and receives packets at up to 11Mb/s.

2.1QoS and Security

The NetLink SVP Server is an Ethernet LAN device that works with the access points (APs) to provide QoS on the wireless LAN. Voice packets to and from the NetLink Wireless Telephones are intercepted by the NetLink SVP Server and encapsulated for prioritization as they are routed to and from an IP telephony server or gateway. See the NetLink SVP Server: Installation, Configuration and Administration document for detailed information about this device.

The NetLink e340/h340/i640 Wireless Telephone supports Wired Equivalent Privacy (WEP) as defined by the 802.11 specification. SpectraLink offers the product with both 40-bit and 128-bit encryption.

NetLink Wireless Telephones support basic WMM™ (Wi-Fi Multimedia) if also supported by the AP as part of the 802.11e protocol. If the AP supports WMM, the handset automatically discovers and uses it. WMM does not replace the NetLink SVP Server.

NetLink Wireless Telephones also support the 802.11i protocol including Wi-Fi Protected Access (WPA™ and WPA2™)—PSK. As vendors introduce access points that are eligible to become Wi-Fi CERTIFIED™ for WPA-PSK and/or WPA2- PSK, SpectraLink will determine their compatibility with the NetLink Wireless Telephones and include them on the NetLink Wireless Telephone Access Point Compatibility Table.

The latest software versions are required to support the features described in this document.
