WiFi signal strength in Tunnels & Subways.

Click For Summary
WiFi signal strength is notably low in tunnels, subways, and underground areas, leading to a lack of wireless network access during travel. Technical solutions, such as the implementation of "leaky feeder" systems, can enhance connectivity by providing continuous WiFi and phone service throughout these environments. While some tunnels utilize this technology, many do not, indicating that the issue is not a technological barrier but rather a matter of implementation. Identifying specific tunnels that lack adequate wireless infrastructure could help address this connectivity challenge.

TL;DR
WiFi signal strength in Tunnels & Subways.
As we see the WiFi signal strength is very low as observed in Tunnels, Subways & Undergrounds while we travel in a train or walk. We do not get the wireless network.

Can there be any technical solutions for increasing the Wireless signal strength in these areas?

Can this be considered a technological barrier?

Many tunnels have a "leaky feeder" system that provides continuous WiFi, phone and radio throughout the tunnel.

I do not believe there is a technological barrier, it has simply not been implemented in your sample of tunnels. Where are the tunnels that need it ?

Thread 'Impersonation News'

A new phenomenon is AI-generated news videos pretending to be by well-known professors Jeffery Sachs and John Mearsheimer. The amazing thing is that they both seem very tolerant of this. Youtube will block these if they request it but this has been going on for months and such blocks never seem to happen. The other surprise is that while they may be visually ugly or even grotesque the news analysis is quite good. If given the sound alone I don't believe I could tell it from the real...
