What it is Beacons Technology –How it works and Its Applications and Challenges Imagine! You come back home after a tiring day from office and are warmly welcomed with a cup of tea. Your home...
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...
When an 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 decodes the...
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 NPSS and NSSS help 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 NSSS, the device will...
NB- IoT frame structure is illustrated in below picture. At the highest level, it starts with the hyper frame cycle where one hyperframe cycle has 1024 hyper frames and each consisting of 1024 frames....
3GPP has defined a set of frequency bands for which NB-IoT can be used. 3GPP TS 36.101 from Release 13 provides the list of the supported bands: 1, 2, 3, 5, 8, 12, 13, 17,...
NB-IoT or NB-LTE is a new 3GPP radio-access technology. It is not fully backward compatible with existing 3GPP devices however it is designed to achieve excellent co-existence performance with legacy GSM, GPRS, and LTE...
LoRa Technology supports the handling and configuration of rejoin-requests for LoRa End Devices. Using a rejoin-request, a device is able to request the network-server to re-activate, without being ‘disconnected’ until receiving the activation. In...
Internet of things has been here for years, but now with Smart Cities deployments, IOT is being seen as the next line of business opportunity for many organization. Many organizations including giants are creating massive...
