5G NR Dual Active Protocol Stack (DAPS) Handover – 3GPP Release 16
3GPP Definition: As per 3GPP TS 38.300 DAPS Handover can be defined as a handover procedure that maintains the source gNB connection after reception of RRC message (HO Command) for […]
NB IOT Peak Data Rate Calculation
We have seen in different literature that Narrow Band IOT (NB-IOT) release 13 technology peak downlink data rate is 170 kbps and pplink data rate is 250 kbps, do know […]
5G NR Transmitted Signal Quality: Time Alignment Error [TAE]
Transmitted signal quality specify how much the transmitted signal deviated from an ideal signal in terms of frequency domain, timer domain or modulation property. The impairments on the transmitted signal are […]
5G NR Transmitted Signal Quality : Frequency Error [Fe]
Transmitted signal quality specify how much the transmitted signal deviated from an ideal signal in terms of frequency domain, timer domain or modulation property. The impairments on the transmitted signal […]
Wavelength, Frequency, Amplitude and phase – defining Waves !
Microwave engineers frequently refers to electromagnetic waves or simply waves and their properties like wavelength, frequency, amplitude and phase. Wave propagation direction is perpendicular to the direction of forces that […]
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. […]
Explaining NOMA basic concept, how is it different from OFDMA and applications of NOMA for 5G ?
Non-orthogonal multiple access (NOMA) has been recently recognized as a promising multiple access technique to significantly improve the spectral efficiency of mobile communication networks. In 1G, 2G, and 3G, frequency […]
What is BTS, Which unit of BTS consumes most of the power ?
A base transceiver station (BTS) is a piece of equipment that facilitates wireless communication between user equipment (UE) and a network. UEs are devices like mobile phones (handsets), computers with wireless Internet connectivity. The network can be that of any of the […]
Revising Direct Conversion Transceiver Radio Architecture, its Sections, Technical Challenges and benefits over SuperHyterodyne
The direct conversion means that an RF signal is directly down-converted to a Base-band (BB) signal or vice versa without any intermediate frequency stages, and therefore it is also referred […]
Why characteristics impedance of RF transmission lines is kept 50 Ohms ?
If you play with RF PCB where RF devices such as amplifiers, filters, couplers etc. are mounted, or you come across RF coaxial cables, you probably know the fact that transmission […]
