Interoperability of Wireless Networks Based on Layer Modification and LTE with 4G

Future generation of wireless communication systems are envisioned to offer higher data rates, higher mobility support, transparent and seamless communication. These requirements open potentials for the operators to increase their service portfolio and for the users to experience context-rich and personalized services. Consequently the interoperability between different wireless network platforms emerges as a crucial necessity. Here focus is given to the significance of the network interoperability aspect based on layered approach and its role in the development towards 4G.This paper gives an overview of the major and differentiating features of 4G from other generations. Attention is also paid to the interoperability provided by LTE.
