Narrow Band (NB) -IoT Modem Chip Vendors

January 31, 2019

There are a number of wireless technologies available for the Internet of things. These are mainly divided into two categories: Short Range (Zigbee, WiFi, Bluetooth, Z wave) Long Range (LoRa, SigFox, NB-IoT ) NB – IoT refers to the technology of the narrowband Internet of things a cellular IoT technology developed as part of 3GPP […]

Maximum Coupling Loss (MCL) and Maximum Path Loss (MPL)

January 31, 2019

Maximum Coupling Loss has been chosen by 3GPP as the metric to evaluate coverage of a radio access technology. In theory, it can be defined as the maximum loss in the conducted power level that a system can tolerate and still be operational (defined by a minimum acceptable received power level). MCL can be calculated […]

IoT nb1 vs nb2 Devices Comparison

January 31, 2019

IoT nb1 vs nb2 Devices Comparison, Narrow Band IoT specifications were first introduced in 3GPP release 13 and then further enhanced in 3GPP release 14 with some essential features. Release 13 NB-IoT device category is referred to as Cat NB1 or Cat N1 and Release 14 devices are referred to as Cat NB2 or Cat […]

LoRa Link-budget and Sensitivity Calculations – Example Explained !

January 30, 2019

LoRa is a proprietary spread spectrum modulation scheme that is derivative of Chirp Spread Spectrum modulation (CSS) and which trades data rate for sensitivity within a fixed channel bandwidth. It implements a variable data rate, utilizing orthogonal spreading factors, which allows the system designer to trade data rate for range or power, so as to […]
