The shortened title is misleading.

"Private operator wants to use other people's wifis to offer service in Tokyo" seems to be a more accurate description.

Btw does Japan have multiple cell phone providers or is this NTT a monopoly?

Also, blockchain? This is not the current hype, it should have been AI powered!

I live in a high-density multi-family apartment block. 300 families in a small space. There are probably at least 300 SSIDs being broadcast in this area, plus Bluetooth and other noise. This is a low-income joint, so amenities are comparatively minimal, but there's just no excuse for not forging a deal with one of the local ISPs and having their WiFi/Ethernet to blanket the property, convincing residents to shut thei…

Sorry but at home I would like to connect to my WiFi, with my preferences and access to my local network. The last time I was forced to use a common access point was in my dorm at the university, and even then I bought a small travel router to rebroadcast the AP.

But I do understand what you mean. I guess one thing to do is to set the router to not broadcast at full power, and use 5GHz to limit the range.

> Tokyo has five million Wi-Fi access points – and that's 20 times what the city needs, because they’re reserved for private use Unsure if you were trying to make a point to debate the article; but it appears they're specifically speaking of private networks, not public.

They don't exist in a vacuum, they all pollute the channels with noise. Public ones indubitably perform worse due to all the private ones.

Its the same in all big cities. From my kitchen I can see 23 other access points in the list. I'm sure we could pool our internet & wifi if we could coordinate, but coordination is too hard.

Given how saturated the spectrum is, its remarkable how reliable wifi has become. I get occasional dropouts (maybe once or twice a day for a few seconds) but otherwise my connection is rock solid. And this is all over 802.11ac - which is super old at this point.

Softbank and KDDI are the biggest competitors afaik, with NTT holding about 50% market share. Big, but not monopoly tier.

Most consumers never upgrade their router, and even if it fails, telcos often send them old and outdated replacements. There's a lot of networks around that are still stuck on older technologies.

> Why does this need a blockchain? Fon/BT has been sharing residential WiFi for years without blockchain The difference is, as per the article, that the Japanese operator wants to re-imburse the WiFi hotspot subscriber. Something which is very much alien to BT's way of thinking. Of course, whether blockchain is the right way do implement that aspect is a different question, and in terms of implementation I would agre…

I really thought we all got off the blockchain bandwagon.

Japan's lagging behind in technology hypes quite a lot.

I don't know how it works on iPhone, but on Android you can easily get a new mac address and get additional 20 minutes. Settings > Developer Options > Wi-Fi non-persistent MAC randomization. Then just forget the network and reconnect.

iOS has “Private Wi-Fi Address” which I think is the same thing

The feature creates a MAC address for each access point and rotates them after 6 weeks without joining. It would be interesting to collect some of these and see if they have anything in common - same OUI, or from a group of OUIs, or totally random, etc.

> Starting with iOS 14, iPadOS 14, and watchOS 7, your device improves privacy by using a different MAC address for each Wi-Fi network. This unique MAC address is your device's private Wi-Fi address, which it uses for that network only.

5GHz doesn’t have the collision problem of 2.4GHz because it weakly propagates through brick and concrete.
