The exponentially increasing demand for higher data rates has pushed the mobile network operators and researchers to scout for ways to improve the system bandwidth, most notably by using the unlicensed band which already hosts long-standing technologies like Wi-Fi. Of late, some effort has gone into exploring the performance of Licensed-Assisted Access (LAA) which can boost the bandwidth of LTE by...
Apart from research being done on using SDN in wired networks, there have been attempts made to extend similar concepts in wireless domain as well, to improve network performance. There have been several architectural proposals put forward which includes concepts like reconfigurable data plane in base-stations e.g. OpenRadio to different Radio Access Technology (RAT). These ideas can be extended further...
Machine Type Communication (MTC) is becoming an integral part of the Long Term Evolution — Advanced (LTE-A) cellular network. Challenges arise when some of the MTC devices, due to the nature of their applications, are deployed in low signal locations. As per 3GPP requirements, there is a need for additional coverage enhancement up to 20 dB in comparison with LTE category 1 UE for MTC devices. In the...
