Satellite broadcasting is very suitable for our consumers. It offers a lot of choices for news, sports, comedy, music, weather and more. Except in steep canyon roads and tunnels, it can be used almost anywhere. Since it does not work in the tunnel, this can cause problems in an emergency. Television and regular radios have a public address system to remind us of emergencies; XM Radio can do the same. The only problem is that these do not apply to road tunnels.
I recently drove through the Boston Tunnel after traveling on the East Coast. I noticed several tunnels cut by XM radio. Of course, I am not surprised because it is difficult to get signals from underground satellites. However, every time I enter the tunnel, I will hear a great song on the TV station in the 80s. The Baltimore Tunnel is not a problem, there is no traffic, I am sailing; no big deal. In New York, the tunnel takes a while to get through the traffic, but it still takes a few minutes, and then the radio is as good as gold. The real problem is that in Boston, the traffic is very intense. I spent nearly 20 minutes in Big Dig for traffic, no radio, behind my CD collection, I couldn't get up. This makes me believe that there must be a better way. The XM radio has a little time delay so you can travel on the highway without switching your music or news on more than 200 channels. However, when passing through long tunnels or canyons, you often miss the signal because you don't have direct sight of the satellite.
I recommend one of two options. A: [We allow government agencies to use all possible channels of all satellite radios and conventional radio stations to play pre-recorded information or B.] We place relays at the end of these tunnels, allowing all satellite radio users to receive signals from the tunnel. If we choose "A", then government agencies will license the use of these signal frequencies for free, and provide fast one- or two-line commercials and public service announcements, such as:
"XM Radio brings you the following statement from the big state's MerryLand; when traveling in the Baltimore Tunnel, stay in your driveway and drive at 45 miles per hour if traffic permits. If you see any Abnormal, please be sure to inform the Maryland State Highway Patrol. Today our alert status has improved and we will rely on your eyes and ears to be there. In order to make Maryland a good place, please drive and always keep Courtesy, thank you for this is the public service announcement of XM Radio and the Maryland State Highway Patrol and Charge Bus Bureau.
If we choose the "B" option, then we need to allow authorized personnel to enter the radio program in the tunnel during heavy traffic, amber alerts, fugitive observations or reminders. Think about it.
