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 […]
NB-IoT PRBs (Physcial Resource Blocks) for In-Band Operation
NB-IoT or NB-LTE is a new 3GPP radio-access technology. NB-LTE requires 200 kHz minimum system bandwidth for both downlink and uplink, respectively. The choice of minimum system bandwidth enables a […]
Narrow Band IoT- Signalling Radio Bearers (SRBs)
Signalling Radio Bearers (SRBs) are the Radio Bearers (RBs) that are used by UE for transmitting and receiving RRC messages with the eNodeB. For NB-IoT UE, only the following radio […]
Features Comparison: NB-IoT UE Vs LTE UE
Table here list the features comparison between Narrow Band (NB) – IoT UE and Long Term Evolution (LTE) UE Features Narrow Band IoT UE LTE UE Master Information Block (MIB) […]
NB-IOT UE Attach Call Flow Messaging
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. […]
NB-IOT Synchronization Signals (NPSS and NSSS)
The NPSS and NSSS helps UE to synchronize downlink to an NB-IoT cell. These are transmitted in certain subframes based on an 80-ms repetition interval. By synchronizing to NPSS and […]
NB-IOT – Physical Broadcast Channel (NPBCH)
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 […]
Maximum Coupling Loss (MCL) and Maximum Path Loss (MPL)
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 […]
NB IOT Cat. NB1 and Cat. NB2 Devices Comparison
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 […]
Narrow Band IoT Frame Structure
NB- IoT frame structure is illustrated in below picture. At the highest level, it starts with hyperframe cycle where one hyperframe cycle has 1024 hyperframes and each consisting of 1024 […]
