How Does LTE Work?

There is no one-size-fits-all cellular network used across the world, and trying to understand how cellular technology works across all the different uses cases is difficult, if not impossible, in a short blog post. So, rather than trying to understand every possible standard, this article will focus solely on LTE networks. Fortunately, competing standards and implementations are roughly similar and we can extrapolate any lessons learned about LTE to other cellular networks without much difficulty. [Read More]

Wireless Networks and Shannon’s Law

All wireless networks (Wi-Fi, Bluetooth, 3G, LTE, etc.) operate using radio signals. Because they operate over the radio, all communication methods have a maximum channel capacity, regardless of technology. This maximum capacity was which is determined by the same underlying principles of information theory developed by Claude Shannon during World War II, known as Shannon-Hartley theorem or Shannon’s Law. Shannon’s Law states that This capacity relationship can be stated as: [Read More]
