Bandwidth conservation

conserving mobile data

There are offline navigation apps like CoPilot and OsmAnd (free) that allow you to download maps on wifi and use them without data while traveling. Note that realtime traffic data doesn't work in these scenarios since the apps are offline.

Google maps will let you download certain map tiles for offline use. This would work best if you are in the same areas but would be less useful while traveling.

Quick Answer: the uBlock Origin browser plugin for Firefox and Chrome/Chromium is simple to use and surprisingly effective. It is a good first step to reducing web bandwidth use.

compression proxies

A compression proxy runs between you and the internet and optimizes / compresses web content to save bandwidth. It may downgrade image quality for substantial savings. It is an internet version of a mail forwarding service that throws out the junk mail and extra packing before sending your mail mail to you.

Note: HTTPS (encrypted) traffic cannot be optimized because it is encrypted and the proxy can't see what it is.

The Opera Mini browser was the first mainstream browser to offer a compression proxy. Now the Chrome mobile browser has a proxy and there is a Data Savings plugin for Chrome/Chromium.

If you are technically minded and have a server somewhere you can run your own compression proxy using freeware like ziproxy.

email frugality

podcast frugality

video frugality

Streaming is evil when bandwidth is limited. Some networking gear is socket-limited; there is a certain number of “slots” available for users. When web browsing, reading email, etc, a user will take one of the slots for active data then release it. Streaming holds a monopoly on the socket, which can block other users from using the resource.

If you must stream use the minimum video quality you can tolerate.

If you can, download the media during off-hours; this is the kindest to the provider and to other users.

“On recent versions of Android (last couple of years) you can pull up the Settings | Apps menu and select the unwanted app. If it was preinstalled you can probably Disable it, which will lock it down. If it was installed afterwards you can Uninstall it from there.

This will stop the creeping background data use and battery consumption.

If you only want to control sneaky data use you can go to Settings | Mobile Data (or Data Usage, depending) and select any apps you see listed as being hogs. Tap on the hog and Restrict app background data. It will still be able to use mobile data when you are using the app but not when you are not interacting with it.

Note: Apps that you intend to run in the background (email, texting, nav, google services, streaming, whatever) should keep access to background data.”1)

conserving wifi data

Wifi is a shared resource, one that is often free as a service to customers. It does not, then, represent an opportunity to waste bandwidth.

The tips for Mobile Data also apply on wifi, but there are couple of chokepoints in a shared resources like wifi:
