Non Orthogonal Multiple Access (NOMA) is proposed technology for future wireless communication. In the evaluation of telecommunication technologies there were different multiple access techniques implemented. In previous generation of wireless technologies time, frequency and coding scheme is used as source of multiple access technique. Time division multiple access (TDMA) implemented in second generation of communication […]

802.11n and 802.11ac came into being, aiming to achieve higher data rates with the introduction of the MAC and PHY layer enhancements. Though Wi-Fi is a resilient technology but not necessarily the most efficient technology owing to the half-duplex nature of the medium only one radio transmits at a particular time. As more users participate in […]

Cellular communication has been evolving a lot in the last decades through massive technological advancement. Experiencing a data speed of few kbps to accessing a bunch of data via video streaming, gaming or video call, totally different experience for a user. Development from the third generation to the fourth generation, the multi-input multi-output (MIMO) concept […]

While taking a phone call with Bluetooth wireless headphones on or typing notes using a Bluetooth keyboard or even checking emails on the Smartwatch have you ever thought that your information is accessible to hackers?   Research in recent times identifies a fundamental flaw  in the Bluetooth standard, affecting every device having Bluetooth capabilities covering a huge […]

The advancement in wireless communication up to 4G, could perform communication over sub 6 GHz band on their maximum capacity due to hardware constrains and requirements in existing scenario. Cellular users are increasing rapidly worldwide and creating congestion in existing spectrum allocation on the other hand users demanding higher data speed for accessing enhanced mobile […]

Network Slicing: The 5G determiner with a big question mark In 5G networks a single physical network is virtually separated into multiple radio access networks (RANs). Network slicing allows a network operator to provide dedicated virtual networks with functionality specific to the service or customer over a common network infrastructure. Thus it will be able […]
