| Voice over WLAN: Come On and Feel the Noise |
 |
The Voice over WLAN (VoWLAN) market has experienced
much hype over the course of 2004, primarily due to the growing presence of Wi-Fi
data networking in businesses and in homes. Much of the interest has been in the
expectation of combination cellular and Wi-Fi handsets, with a vision of the end-user
being able to switch seamlessly between cellular and Wireless LAN (WLAN) networks,
while simultaneously maintaining a call.
The VoWLAN market is really divided into four segments at this stage, however.
The four areas include the following: (1) VoWLAN handsets for the enterprise,
(2) VoWLAN handsets for the home/SOHO, (3) soft phones, (4) and combination cellular/VoWLAN
handsets.
802.11b enterprise VoWLAN handsets have been shipping out the door since
2000. SpectraLink and Symbol have been the leaders in this market for the past
few years, selling handsets mainly to the verticals of healthcare, education,
retail/warehousing/distribution, and manufacturing. Cisco introduced its VoWLAN
handset in mid-2003. With total handset shipments totaling less than 60 thousand
in 2003, this market is still a niche market, however. Factors hindering large
volume shipments include the relatively high cost of handsets (generally an ASP
of $600), and the lack of standardized QoS and fast roaming. |
