Narrowband Internet of Things (NB-IoT) Overview – Post from Grandmetric Advisor

Narrowband Internet of Things (NB-IoT) is a secure, reliable, and efficient type of Low-Power Wide-Area (LPWA) Technology that was standardized by 3GPP in Release 13 (LTE Advanced Pro) and uses licensed spectrum.

What are the practical aspects of LTE, LTE-Advanced Pro and 5G? – A new book.

This book guides you through the LTE, LTE-Advanced Pro and 5G from the perspective of practical aspects of air interface, RAN, Core Network and end-to-end data transfer. The practical approach is reflected by the angle of system design, link budget process, network planning, parameter configurations and optimizations together with the required tradeoffs. We also evaluate the different features’ impact on the overall system as it evolves from LTE to LTE-Advanced and then going further to LTE-Advanced Pro and 5G.

LTE-Advanced Pro – what is this?

  As 3GPP Rel-13 has been already frozen (with the exception of Narrow Band IoT), the time has come to provide an overview for the evolved LTE under the name of LTE-Advanced Pro. As already mentioned in one of the previous articles (LTE evolution: from LTE, via LTE-Advanced, towards LTE-Advanced Pro), LTE-Advanced Pro is a […]

LTE evolution: from LTE, via LTE-Advanced, towards LTE-Advanced Pro

  In this article I’m sharing a short overview of the LTE evolution, starting with its introduction within 3GPP Release 8 back in early 2009 up to LTE-Advanced Pro to be finalized in March 2016 within Release 13[1]. Timeline, main features and a maximum throughput calculation is provided for each of the evolution steps.   […]
