You don't. I don't. Others do. It's also plug and play. People love that.
Covering a house with WiFi is cheapish. But still not free. And these are meant for more than just houses.
A business blocks access to WiFi or has consent pages to protect themselves and their network. If they are a Sprint customer or have a lot of Sprint users, a MB is a free way to cover your building/office area. Every place I have ever worked blocks or has guest captive portal on WiFi. Yet still have a DAS.
It's isn't a way to abuse the network, it's a way to waste Sprints financial resources (people who don't need it but want to use it like me).
Don't know. I was barreling down the highway at the time I took the picture, and I don't usually do speed tests anyway. But considering the available speed used to be zero, I'm going to say it's decent, sure.
On my way home today, I'm going to take a long route to check on some more sites I don't usually go by. Expect the Premiere map to fill in some after I get home.
(Also, I'm amused that with yesterday's update to the Sprint coverage map, the Red House tower that's on the air is now missing from the map along with the Hat Creek tower, while the Sugar Hill site that had no antennas two weeks ago is still present.)
