Question Response
What if I already have a wireless router? The T-Mobile @Home HiPort ™ is the only router of its kind that works with the T-Mobile @
Home service. This wireless router may be connected to your existing wireless router.
Will T-Mobile become my Internet service provider
(ISP)?
No. T-Mobile will only provide your phone service. Your wireless router connects to the Internet,
so you must have a separate Internet service provider (ISP) for the high-speed Internet connec-
tion.
How secure is the T-Mobile @Home HiPort™? Corded home phone calls are sent over the Internet and are very secure. Cordless phone call
security is dependent on the cordless phone’s voice encryption between the phone and the
phone’s base station. For increased security, plug a corded phone into the wireless router.
Note: T-Mobile does not make specic recommendations on the best method of securing a local
network.
Will the wireless router work with a rewall? Our wireless router uses industry standards for security. Simply put, if you can set up your lap-
top behind your rewall, you can connect with our wireless router.
For rewalls, UDP should not be blocked for those two ports 4500, 500. It’s recommended that
in business settings, you work with your IT support person if you do not have access to modify
the settings. It is also possible that an IT support person might have other settings congured
that would cause difculties for the cabled or wireless portion of the router.
How do I set up the wireless router? T-Mobile @Home is designed for you to set up easily.
Use the Setup CD packaged with the wireless router.
For non–Windows-based computers, use the setup poster included in the box.
Where should I put my wireless router? Cordless phone reception is not based on the location of the wireless router, but rather on the
location of the base unit for the cordless phone relative to the other cordless phones.
T Mobile @Home is generally not affected by radio frequency (RF) interference. T-Mobile
recommends a DECT 6.0 phone, which has signicantly less interference than the standard
900-MHz, 2.4-GHz, and 5.8-GHz phones. Even corded phones can have interference from radio
stations.
What devices can cause radio frequency (RF)
interference?
Any device that uses the 2.4-GHz spectrum may cause RF interference with T Mobile @Home.
Examples include:
2.4-GHz cordless phones•
Baby monitors•
Microwave ovens•
Some home video-surveillance equipment•
When using other wireless routers, remember to congure them on different channels, or dis-
able wireless on the routers you are not using for wireless Internet.
What are the bandwidth requirements for
T-Mobile @Home?
A broadband Internet connection is required to place calls over Wi-Fi. Each voice call can use
up to 70 Kbps upload/download speed. Most consumer high-speed connections have at least
256 Kbps, which is recommended to allow for other activities.
How many people can use this service at one time? The T-Mobile @Home HiPort™ supports up to two lines of T Mobile @Home service. The actual
number of calls the wireless router can handle depends on the bandwidth you have from your
ISP. A typical high-speed connection can support ve concurrent calls at a time, including those
made over HotSpot-enabled phones (dependent on Internet connection speed and bandwidth).
Can I buy the T-Mobile @Home HiPort™ without
getting the T Mobile @Home service?
Yes, you can purchase the T-Mobile @Home HiPort™ without getting the T Mobile @Home
service, but discounts or rebates may not apply.
