Nope! Consider the Bart problem, and then after that, consider the Wyoming problem. And then think about the India problem. Wifi just isn't available much of the time. It's important for apps to build out functionality for core user journeys in offline mode.
Of course, you can't offline the whole internet... But with reasonably good personalization, you can get some of the parts that matter most. For example, in the case of a food ordering system, the app can know the menus for restaurants used before, and have those ready to go offline. And then get the menus for restaurants that match the user profile, in the local area.
- DiabloD3 10y agoAhh, the Google methodology of caching based on physical locality. That works well for the client side... I was suggesting Unifi AC AP Pros to fix the restaurant side if they need to fix their Wifi issues. Also, Elon Musk now has the go ahead to put LTE-in-the-sky sats everywhere. Aren't in range of a tower? You probably have a wide open shot of the sky.
- Fnoord 10y agoWhat is the Bart problem?
- throwanem 10y agoSince everything else I've ever heard about BART is bad, I'm going to surmise that mobile connectivity while riding it is bad too.
- mberger 10y agoIm not from the states either but I assume it's the Bay Area Rapid Transit, or the subway. I'm assuming wifi is spotty because of the difficulty of connecting to a moving access point. No idea what the Wyoming problem is. Im assumign the India problem is access point overloading.
- gvb 10y agoThe Wyoming problem is miles and miles of empty land with no cell towers within reach.
- Fnoord 10y ago> Im not from the states either but I assume it's the Bay Area Rapid Transit, or the subway. I see. Since its an acronym and doesn't reference to a person named Bart lets call that the BART problem. > Im assumign the India problem is access point overloading. On WiFi? In large cities the WiFi problem is bigger, but 5 GHz alleviates a lot of the pain if you are stationary. I've been seeing a lot of cheaper phones (even recent) only having 2,4 GHz. My router can only set itself it either 2,4 GHz, or 5 GHz, so having one device which only can do 2,4 GHz is a problem. In large cities, the solution here appears to be more 4G APs. If you're moving, 4G (or WiFi AP in the mobile vehicle using 4G like the trains have here) solves the problem since it supports roaming very well and has a longer range than WiFi. There's also the option of Femtocell. For subway systems, the tunnels are already there (which includes safety exits and such) so building connectivity via Femtocells seems like a logical way to solve the problem. This does have a cost attached to it, and also planning and testing.
- sdenton4 10y agoIndia is mostly 2g and 3g, though there's a major new 4g network being rolled out now. That said, recent studies show that 4g networks greatly reduce in speed as they near capacity; many US cities have seen 4g speeds cut in half as more people have come into them.
