How does router work?

As you might be aware, bits are a form of language for machines and packets are series (groups) of these bits that traverse the network. The mechanism via which these packets travel across the network is organized thanks to Internet Protocol (IP is set of common rules, structures and descriptions). In general, we have: END DEVICES (like […]

What is Light Fidelity (LiFi)? – A Guest Post from Grandmetric Advisor

Light Fidelity (LiFi) was introduced by Prof. Harald Haas, from the University of Edinburgh in the UK, in his 2011 TED Global Talk titled “Wireless Data from Every Light Bulb”. It is a new broadband wireless communication technology similar to WiFi, but it uses visible light communication (VLC) instead of radio frequency used by WiFi.

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.
