Carlos Rincón Castro; Aurely Leal Lozano; Jenny Pantoja Blyde

ABSTRACT

Today, technologies used to deploy cellular networks have as main feature the increase of data transmission rate, due the need to offer voice, data and multimedia services (triple play). However, most part of cellular networks used around the world are based on 2.5G technologies, which have as restriction the data transmission speed. Service Providers are searching for applications that allow 2.5G networks to offer attractive service to users, increasing the life of the network infrastructure. Unlicensed Mobile Access (UMA) is the use of Wi-Fi network spectrum (IEEE 802.11 and others) to connect the user with the service provider, using VoIP technology to minimize the interconnection cost and to offer a wider range. The purpose of the present work is to analyze the advantages and disadvantages of UMA technology and to dissert about its future deployment on 2.5G networks.

Key Words: Unlicensed Mobile Access, 2.5G technologies.
