Many small offices and homes are installing wireless LANs to support mobile access to
common Internet applications. Service providers, such as Vonage, are strongly advertising
the capability of using the Internet for making phone calls to augment or replace standard PSTN telephones. Home and small-office owners are taking advantage of Internet
telephony to save money on long-distance phone calls.
The use of VoWLAN is further extending the benefits of VoIP by providing mobility and
even replacing the need for a cellular phone. A consumer is likely to select a VoWLAN
solution as compared to wired VoIP service to enable mobility similar to what cordless
phones offer. Someone can take the phone around the house and talk while doing house
chores.
A single access point can easily support most home and small-office voice applications.
Range is sufficient for the entire home, and a single 802.11b or 802.11g access point can
support the limited number of phones (generally only one) that will be in use simultaneously.
RF interference from microwave ovens and neighboring wireless LANs set to the same
channel can cause significant impacts on performance, however. Consumers may have
to reconfigure the RF channel of their access point to have effective wireless voice
service.
Unfamiliarity with wireless technologies may preclude some consumers from purchasing
VoWLAN equipment. In addition, the inability of Internet telephony to operate during
power outages and limited operation of 911 services may keep some consumers from
moving forward with a wired or wireless VoIP solution. Despite these issues, though,
VoWLANs in homes and small offices is expected to proliferate over the next few years.
Home owner finds value in Internet telephony
Madison Leigh of Fairborn, Ohio, found that her monthly long-distance phone bill was
running more than $100 per month because she was making regular phone calls to her
father, living in a rest home in Chicago. Madison was paying only 10 cents per minute,
but the phone calls were running into the hours, discussing issues that her father was
having living in the rest home. Madison saw an advertisement on television for Vonage
Internet-based calling, so she investigated the service and found that it would save her
approximately $70 per month. After hearing about Wi-Fi, she found that she could have
wireless voice over Internet connectivity, which she thought was a good idea because she
could talk on the phone from anywhere in the house, similar to what her cordless phone
had been providing.

business specializing in the repair of foreign automobiles and the sale of hard-to-find
automobile parts to car enthusiasts worldwide. Jack employs eight mechanics and one
administrative person, who takes care of invoicing and paying the bills. Jack supervises the mechanics and provides necessary guidance on the shop floor. He is on the phone
most of the day, making international calls, trying to locate rare parts worldwide for
fixing the cars. His phone bill had been running nearly $1,000 per month! When
purchasing a new fax machine at a local office supply store, he saw a Wi-Fi phone and
router advertising the ability to slash long-distance phone call costs, especially overseas.
After thinking about it a bit and doing some research on the Internet, Jack purchased the
solution and installed it at his company. He now pays roughly $50 per month in
phone bills.
