How to Build a Low-tech Internet

Post by Dreamweaver » 09 Jan 2018, 20:33

A long read, this includes thoughts on and pictures of the following items.

Picture: A node in the Scottish Tegola Network.
WiFi-based Long Distance Network

Long-distance WiFi links require line of sight to make a connection -- in this sense, the technology resembles the 18th century optical telegraph.
Advantages of Long Range WiFi
Litebeam M5Long range WiFi offers high bandwidth (up to 54 Mbps) combined with very low capital costs.
Long Range WiFi makes use of unlicensed spectrum and offers high bandwidth, low capital costs, easy installation, and low power requirements.
Long Range WiFi Networks in Poor Countries

WiFi-Based Community Networks in Europe
In a community network, the users themselves build, own, power and maintain the infrastructure.

Performance of Low-tech Networks
The available bandwidth per user can vary enormously, depending on the bandwidth of the gateway node(s) and the number of users, among other factors

Delay-Tolerant Networks
Data Mules

Delay-Tolerant Software

Resilient Networks

Such a hybrid system of online and offline applications would remain a very powerful communication network -- unlike anything we had even in the late twentieth century. Even if we envision a doom scenario in which the wider internet infrastructure would disintegrate, isolated low-tech networks would still be very useful local and regional communication technologies. Furthermore, they could obtain content from other remote networks through the exchange of portable storage media. The internet, it appears, can be as low-tech or high-tech as we can afford it to be.
