Unlicensed Mobile Access Presented by: Alexei, Ashley, Ryan, Tommy

U.M.A  Developed by UMA Consortium  Participants include: Cingular, Motorola, Nokia, and T-Mobile  Definition: allows the transfer and switching of cell phone receptions to unlicensed wireless networks, local area networks, and a public switched network to enable the most optimum reception available

UMA Process  A subscriber makes a call with a UMA enabled phone  Once the call is in place, the signal is sent and must be approved by the unlicensed access network  Upon approval, the user’s mobile phone is shifted seemlessly to the best available networks at any given time.  Prevents any existence of roaming.

Advantages of UMA  Co-exists with systems such as, Wi-Fi and Bluetooth  Doesn’t require modems, routers, and access points  Eliminates poor reception in buildings

Conclusion  Questions and Comments Thank you for time and patience!
