NPBCH stands for narrow band physical broadcast channel similar to PBCH in LTE Technology. The 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. NPBCH uses a 640 ms TTI, but within the TTI only subframe 0 is used … Read more
When a NB-IOT UE accesses a cell, it follows the same principle as for LTE: It first searches a cell on an appropriate frequency. Decode NPSS and NSSS for NCellID. After decoding NCellID, UE decode the NB-MIB Information transmitted over NPBCH, but there it can get to know NB-LTE deployment mode i.e. In-band, Guard-band or Standalone, the schedulingInfoSIB1, … Read more
Narrow Band IoT specifications was 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 as Cat NB1 or Cat N1 and Release 14 devices are referred as Cat NB2 or Cat N2. Parameter Cat. NB1 Cat. NB2 3GPP Release … Read more
Energy is the most scarce resource for an electronic device and when someone designing it, he needs to optimize its operation so that it consumes minimum power. When a device has a regular power supply along with the battery backup, one will not be worried but in the case where the device has an only battery as … Read more
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 Release … Read more

LTE band B42 and B43 mapped to CBRS frequency spectrum. CBSD devices are categorized into two types: CBSD-Category A CBSD-Category B CBSD-Category A : CBSD Category A shall not be … Read more
CBRS Network Architecture: CBRS is known as Citizen broadband radio service, It is a 150 MHz wide broadcast band in 3.5 GHz band starting from 3550 MHz to 3700 MHz. In 2017, the FCC completed a process to establish rules for commercial use of this band. Commercializing this band enables Service Providers/Wireless Operators to use it without … Read more
Citizens Broadband Radio Service (CBRS) is a 150 MHz wide broadcast band in 3.5 GHz band starting from 3550 MHz to 3700 MHz. The Federal Communications Commission (FCC) regulates interstate and international communications by radio, television, wire, satellite, and cable in all 50 states, the District of Columbia and U.S. territories. In 2017, the FCC completed a process to … Read more
