Abstract

A satellite distributed high-speed Internet “Hotspot” enables wireless and hardwired, satellite distributed Internet access aboard a transit vehicle such as a train for anyone with a PC or other web-ready device (wireless ready or cabled) and a valid credit card or prepaid coupon. Internet access is obtained via a ground-based satellite dish, which is operatively coupled to a wireless access point located along the transit route such as a railroad track. The wireless access point is in communication with a wireless transceiver unit located on the transit vehicle, and the Internet signal is distributed to users on the transit vehicle via a router using wired or wireless connections. A plurality of wireless access points can be located along the transit route, thereby allowing the transit vehicle to maintain the Internet connection while traveling along the transit route.

24. The method of claim 1, further comprising:

prompting the user device for a user name and password, verifying the password and an account status for the user device, and thereafter enabling the user device to access the Internet.

25. The method of claim 24, wherein upon establishing the connection with the remote server, the remote server is viewable at the user device as a webpage in a Secure Socket Layer (SSL).

26. The method of claim 24,

wherein the transit vehicle is a train and the transit route comprises a railroad track, and

wherein the user device comprises a cell phone.
