LTE eNodeB Scheduler and Different Scheduler Type
What is a LTE Scheduler ? Scheduling is a process through which eNodeB decides which UEs should be given resources (RBs), how much resource (RBs) should be given to send […]
Spectral Efficiency : 5G-NR and 4G-LTE
What do you think of when you hear word “spectral efficiency?” The answer will come, it has to do with the amount of information that fits in a given channel […]
3GPP Release-15 UE Cat Types, Throughput, Modulation and DL / UL Combinations
UE Category information is used to allow the eNB to communicate effectively with all the UEs connected to it. The ue-Category defines a combined uplink performance capability and downlink performance capability. […]
Explain LTE Frame Structure both for FDD and TDD
Time duration for one frame (One radio frame, One system frame) is 10 ms. This means that we have 100 radio frame per second. Let’s look at the frame structure: […]
LTE Control Plane and User Plane Latency Calculation (FDD)
LTE- is designed to support peak data rates of 300 Mbps in the downlink and 75 Mbps in the uplink with 4×4 MIMO support along with C-Plane latency less than […]
Drone Wireless Video Transmission – Technologies, Challenges and Probable Solutions !
Lately, drones have become very popular both as professional tools and for recreation and air sports competitions. Drone or UAV (Unmanned Aerial Vehicle) are generic terms that includes many types of […]
What does noise figure signifies, Give a calculation example for Receiver chain ?
Noise figure is a number by which the noise performance of an amplifier or a radio receiver can be specified. Lets start with Signal to Noise Ratio of an amplifier. […]
How to choose an Antenna for your application ?
Choosing an antenna can be a difficult task, there are several parameters that need to be taken into consideration. Although It is important to examine several physical, electrical, and economical […]
What is physical significance of IP3, why it is more important in Receiver Chain ?
Understanding physical significance of 3rd order Intercept Point (IP3) When an amplifier or other circuit becomes non-linear, it will begin to produce harmonics of the amplified inputs. The second, third, […]
What is Inter Symbol Interference (ISI) in LTE, How Cyclic Prefix (CP) helps eliminating this problem ?
What is Inter Symbol Interference (ISI) ? In an ideal system (theoretical), the transmitted symbols arrive at the receiver without any loss or interference, as shown in the following figure. […]
