GSM is the most successful mobile technology nowadays; moreover the market share of GSM is still rising. To maintain this rate of growth new services are needed. As it was in case of fixed telecommunications networks it seems that in the wireless networks mobile data providing is going to be the service driving the market. As mobile network operators face the growing demand, they have multiple choices to make their networks capable of providing higher data rates. The coming era of 4g systems is foreseeing a potential smooth merger of all these heterogeneous technologies with a natural progression to support seamless cost-effective high data rate global roaming, efficient personalized services, typical usercentric integrated service model, high Qos and overall stable system performance. However, every step in such technological advancements presents huge research challenges. This article aims to focus upon some of these potential challenges along with different proposed feasible and non-feasible solutions in the areas of mobile terminals and users, mobile services, mobile and wireless access networks, and communication, in order to give an in-depth view of the next-generation communication systems.
