5G Networks: Use-Cases By Vikram Singh5G networks are designed to support many use-cases for variety of scenarios and terrains. These use-cases have different latency, date-rate and scale (number of devices) quality of service requirements. The requirements are defined in terms of bit/block/packet error rate, throughput (spectral efficiency, energy efficiency), latency, power consumption (complexity of algorithms),…
Design new standards for emerging technologies By Vikram SinghDifferent standardization bodies define the specification for different systems. One such standardization body is 3GPP which define protocols for 4G and 5G networks. The standards are designed separately for layer-1 (physical layer), layer-2 (MAC layer, radio link control layer, Service Data Adaptation Protocol (SDAP) layer and Packet…
Understand your algorithms better By Vikram SinghAcademia has paved a way for industry by designing state of the art algorithms and methods such as orthogonal frequency division multiplexing and access (OFDM(A)), LDPC codes, Polar codes etc. However lately, the contributions (innovations) per paper has drastically reduced in academia compared to the previous decades. One major…
Network Design and Optimization By Vikram SinghWireless communication network consists of two parts (network infrastructures), the radio access network (RAN) and core network (CN). 4G-BWSim and 5G-BWSim focus on the RAN infrastructure which consists of three layers L1, L2 and L3. 4G simulator can simulate all the three layers whereas the 5G simulate the layer…
