A Note on 5G & Its Slicing as a Real Estate Play

【推荐读物】Recommending this insightful and objective article by Benedict Evans from a16z – 5G: if you build it, we will fill it.

Below is an excerpt of his comments on slicing…

One of the cooler features of 5G is that it lets you split out dedicated capacity for particular use cases – so-called ‘network slicing’. Today (to simplify hugely), although network operators try to do traffic management, all traffic in the cell is fundamentally using the same capacity. 5G lets you create dedicated private capacity in the radios network with specific characteristics. So, you could sell a truck operator dedicated capacity on the two miles between a specific freeway exit and a specific warehouse. Or, you could offer an IoT operator (or alarm company) much lower bandwidth but over a wider area.

／《宇宙的琴弦》—— 布赖恩·格林
11 月读完

一本深入浅出讲述物理上的弦理论的书。广义相对论和量子力学的**不兼容**是物理学中的世纪难题，superstring theory (超弦理论) 是目前可以**统一两者**，并可能成为**物理学“终极理论”**的理论 (M 理论)。作者先分别阐述了广义相对论和量子力学，之后尽可能易懂地描述了超弦、高维空间等。部分内容读起来还是比较难，但这已然是最好的科普级别。

17. Running on Empty: How the Democratic and Republican Parties Are Bankrupting Our Future and What Americans Can Do About It by Peter Peterson
／没有找到中文译本
12 月读完

一本 2004 年的书，作者是上面提过的 Blackstone co-founder，不留情面的描述了美国的 twin deficits (财政赤字和贸易赤字)，以及美国两党 – 在选民面前，共和党抓着 tax cuts，彰显 how little they can give to government，民主党抓着 healthcare，彰显 how much they can take from government；与当下的美国对比起来极其有趣。
