MH110/MH120 IP Wireless Telephone Setup and Administration Guide - Revision 1

System Components

• The

MH110 is a lightweight, durable handset specifically designed for

mobile workplace use within a facility using the supported NEC IP

telephony system and 802.11b APs in a wireless LAN.

• The

MH120 offers a durable design with push-to-talk functionality.

The MH110/MH120 functionality is provided by emulating the NEC

DtermIP-16LD. Among other features, the Mobile Handset can receive

calls directly, receive transferred calls, transfer calls to other

extensions, and make outside and long distance calls (subject to the

restrictions applied in your facility.) The Mobile Handsets are to be

used on-premises; they are not cellular or satellite phones.
UNIVERGE WL Mobile Handsets use Direct Sequence Spread Spectrum

radio technology (DSSS) to transmit audio packets over wireless LAN

APs that support SVP Server.

•

SVP

Serv

- SVP Server is the NEC quality of service (QoS)

mechanism that is implemented in the Mobile Handset and AP to

enhance voice quality over the wireless network. SVP Server gives

preference to voice packets over data packets on the wireless medium,

increasing the probability that all voice packets are transmitted

efficiently and with minimum or no delay. SVP Server is fully

compatible with the IEEE 802.11b standards.
The SVP Server is an Ethernet LAN appliance that works

with the AP to provide QoS on the wireless LAN. All Protims packets to

and from the MH110/MH120 pass through the SVP Server and are

encapsulated for prioritization as they are routed to and from the

supported NEC VoIP solution or other Mobile Handset.
SVP Server is required for QoS because the current IEEE 802.11b

wireless LAN standard provides no mechanism for differentiating

audio packets from data packets. This standard is undergoing revision

to version 802.11e to provide all the functionality of SVP Server in an

industry standard, thus ensuring high-quality voice in a mixed client

environment. Once 802.11e is ratified, NEC and its 802.11b

technology partners will adopt the new specification.

•

NEC IP System - NEC VoIP solution.

•

Access Points - supplied by third party vendors, access points

provide the connection between the wired Ethernet LAN and the

wireless (802.11b) LAN. Access points must be positioned in all areas

where Mobile Handsets will be used. The number and placement of

access points will affect the coverage area and capacity of the wireless

system. Typically, the requirements for use of MH110/MH120 are

similar to that of wireless data devices.
Access points must utilize SVP Server. Contact NEC, or a certified

NEC distributor, for information about APs that support SVP Server.
