  • FAA names airports protected by C-Band 5G rollout buffer

    I read this and wondered how large the exclusion zone is exactly? It's not AI's fault that they did not mention it. The story here is pretty much identical to one posted in many news sources today. Some digging turned up the answer: About one mile. The FAA is restricting 5G in places where it could affect aircraft within the last 20 seconds of flight in the USA (compared with the last 96 seconds in Europe). The US also broadcasts 5G at higher power than in Europe which is why the FAA is still concerned about how it could affect aircraft radio altimeters on precision approaches especially during low visibility conditions. To work out that the distance is about a mile, I looked at the approach speed of aircraft. That's 30% above their stall speed. Their stall speed is based on the weight of the aircraft. A 747 has an approach speed of 166-172 MPH. Divide 172 by 60 is 2.86 miles per minute. Divide that by 3 and you get 0.96 miles. So it's about a mile. Not sure if this is only over the flight paths but it's a likely guess. The exclusion zone is some kind of weird ameba shape around the airport and the approaches following a signal strength contour.

  • The AirTag stalking problem is only partially Apple's problem, it's mostly law enforcement...

    So if I was to create some new product that could easily be used by one person to harm another I can just say that it's law enforcement's responsibility? Really? Let's bring back lawn darts!

    Before anyone gets too excited about a hole punch camera, consider this invisible, behind the screen front facing camera in this ZTE phone released a year ago now and two years before the iPhone 14:

  • HDMI cable purchasing is about to get a whole lot more complicated

    It's easy. Just read the clearly labeled spec version that's printed on the HDMI plugs ... not.
    The HDMI forum should replace the people who make decisions. They are useless.

  • Apple execs explain why you should use Apple Maps over competitors

    Even after years of development, Apple Maps still won't give you directions to a specific store in an outdoor mall. It still just drops you at the entrance to the parking lot. Google Maps will give you precise directions to the correct store. There are still reasons to use Apple Maps such as its excellent Siri integration (hey Siri, directions home) and amazing synthetic voice that manages to pronounce every street name perfectly and it conversational English. Keep Google Maps as a backup for when Apple Maps fails you.
