Narrow Band-Physical Broadcast Channel (NPBCH)

January 31, 2019

NPBCH stands for narrowband physical broadcast channel similar to PBCH in LTE Technology. The Narrow Band-Physical Broadcast Channel (NPBCH) is used to deliver the NB-IoT Master Information Block (MIB), which provides essential information for the NB-IoT UE to operate in the NB-IoT network. Narrow Band-Physical Broadcast Channel (NPBCH) uses a 640 ms TTI, but within […]

5G Channel Models: Requirements and Deployment Scenarios

November 8, 2018

5G Channel Models: Requirements and Deployment Scenarios Propagation Channel Model: A channel model is also known as radio wave propagation model, it characterizes radio wave propagation as a function of frequency, distance, environment, and other factors. In other words, we can say that channel model provides us rough idea how much distance a signal can […]

5G Absolute Radio Frequency Channel Number (NR-ARFCN)

October 31, 2018

5G Absolute Radio Frequency Channel Number (NR-ARFCN) An Absolute Radio-Frequency Channel Number (ARFCN) is a code that specifies the a pair of reference frequencies used for transmission and reception in radio system. In a FDD system one ARFCN number is required for downlink and another for uplink  as downlink and uplink frequencies are different while for TDD system […]
