The development of new technologies has forced carriers to seek more powerful solutions to adapt to the needs of competition and meet the increasingly stringent requirements of users for data services. 3G is a challenge for all parties, but regardless of the heavy cost pressure of 3G systems, wireless carriers must enable their networks to handle more complex data services without affecting voice traffic. Therefore, more network equipment is needed. This article will help component and design engineers identify which solution will be most suitable for their wireless system equipment.
