In today's hyper-connected society, everyone constantly uses their smartphone,
|
|
|
|
|
which in turn uses the commercial cellular networks (from 2G/GSM to 4G/LTE)
|
|
|
|
|
in order to achieve connectivity. However, contrary to WiFi technology, even
|
|
|
|
|
most technology-minded people don't have much of an idea how the infrastructure
|
|
|
|
|
behind those cellular networks looks like.
|
|
|
|
|
|
|
|
|
|
This talk does not cover the architecture and protocols of underlying
|
|
|
|
|
cellular systems, but focuses on the physical side of things:
|
|
|
|
|
* what are the typical components of cellular base stations?
|
|
|
|
|
* what are their key functionalities?
|
|
|
|
|
* how did cellular base station technology evolve during the past 20 years?
|
|
|
|
|
* how do we expect cellular base stations to change in the [near] future?
|
|
|
|
|
|
|
|
|
|
We will not cover DIY or hobbyist projects here, but the actual technology deployed
|
|
|
|
|
in the field by real-world commercial operators.
