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: […]
What are the important parameters to look for while choosing PCB material ?
In order to design PCBs intelligently it becomes important to understand, among other things, the electrical properties of the board material. Understandably, these materials are the foundations for many circuits, […]

Explain Radio Requirement Set for 5G NR (1-C, 1-H, 1-O, 2-O BS Types)
The capabilities of 5G NR wireless access must extend far beyond previous generations of mobile communication. Examples of these capabilities include very high data rates, very low latency, ultra-high reliability, […]
How Conventional AGC (Automatic Gain Control) works in receiver chain and its important parameters.
In wireless communication systems such as LTE, the received signal has an unpredictable signal power and varies over a wide dynamic range caused by multi-path fading channel and unwanted signals […]
5G NR (New Radio) Frequency Bands
Recently, 3GPP has freezes specification for 5G NR and TS 38.104 section 5.2 provides the list of bands in which NR (New Radio) can operate. As per 3GPP release 15 […]
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 […]
LTE Handover Latency Calculation (Access Node)
In a cellular system, handover can be defined as a procedure to transfer a User Equipment (UE) and its context from a source cell to a target cell when source cell […]
Feature Group Indicators (FGI bits) in LTE – Rel. 8, Rel. 9 and Rel. 10
Feature Group Indicators (FGI bits) Feature Group Indicator (FGI) is a special Information Element (IE) within UE Capability Information message. The parameters other than FGI in UE Capability Information message […]
