FAQs

Q: Is the BlackBerry Curve 8320 the only UMA device available?
A: No, there are currently two flip-phones available – Nokia 6086 and Samsung t409.
More devices, including a new Windows Mobile device, will be available in Q1 of
2008.

Q: Will my cellular minutes be used while I am on the wireless network?
A: No. As long as you are connected, you will not be using your cellular minutes
and you will be receiving clear coverage.

Q: If I switch from my current carrier to T-Mobile, will I keep my mobile phone
number?
A: Yes. We will port your cell number over to your new T-Mobile device.

Q: How can I understand that I am on a wireless network vs. a cellular network?
A: The signal strength indicator on the phone changes to a different shape and color
and says EDGE when it is on the cellular network. This indicates cellular minutes
are being used. It will say UMA along the signal strength indicator when in a Wi-Fi
environment.

Q: Will a call be interrupted when I leave the WiFi network for the cellular network?
A: No. The call will seamlessly switch between the two networks without
interruption.

Q: Are the phone calls I make on a WiFi network secure?
A: Yes. The phone calls are just as secure as the calls placed on the cellular
network.

Q: How do I use my UMA phone at home or another location outside of my office?
A: As long as there is an accessible wireless network, you can use your UMA
phone while not using your cellular minutes. It is an easy three step process to
connect for the first time.

Q: Once I have created a new wireless connection with my UMA phone, do I need to
recreate it the next time?
A: No. The phone stores all of the networks you have saved and will recognize the
network when you return and automatically connect.

Q: What information is needed from me to begin the process?
A: Once we have completed the WLAN Site & Cellular Service Surveys, we can
begin the process of quoting and installation. Most applications can be up and ready
to use within two weeks.

Q: Is there a technical reason that coverage inside a building might be bad? For
instance,  is it simply because you are inside or is it due to interference, etc.?
A: The issue is frequency. Older analog cell phones used lower frequencies. Lower
frequencies travel farther and penetrate buildings better. New digital frequencies that
are being used today support higher bandwidth, but they don’t transmit as far and
they do not penetrate buildings well.

Q: I currently have a WLAN in my office. Can I use the UMA phone on this network?
A: It may work but will not give you optimal service or coverage. RACO Wireless will
determine, through a site survey, if your network is optimized for phone traffic and
the wireless coverage extends to all areas where the phone would be used.

Q: Other than the UMA phone, can I use the WLAN for other purposes?
A: Yes. The WLAN is open to other wireless devices such as notebook computers,
print servers, data collection devices and other wireless products.
