Have you ever wanted to go from Beijing to Guangzhou in 8 hours? If so, your dreams just came true.

Yesterday, the longest high-speed rail line was opened in China, stretching 2,298 kilometers or 1,428 miles. As mentioned before, it will only take 8 hours to complete the trip. Before this line, the fastest rail connection would get you to Beijing or Guangzhou in 20 hours.

The feat is done with the help of trains traveling at 300 kph or 186 mph. Furthermore, over 150 pairs of high-speed trains will be on this new rail line every day.

This line marks the halfway point in China’s high-speed rail plan. By 2020, the Chinese government plans to criss-cross the country with a grid of high-speed rail lines. Also, with the completion of this line, China now has over 9,300 km or 5,800 miles of high-speed rail lines and has no plans to stop building. In fact, China hopes to double this amount by the end of 2015.

Would you like to see high-speed rail in your neighborhood? Do you already use high-speed rail to get around? Let us know in the comments below.

The Bluetooth Special Interest Group (SIG) is currently working on a new standard for Bluetooth that would effectively piggy-back or work with a WLAN (Wi-Fi) based connection. As it stands, you can only get a maximum speed of about 3Mbps. The new standard can bump that up to 24Mbps.

Dubbed Bluetooth 3.0 + High Speed (BT 3.0+HS), this is the next logical step beyond Bluetooth 2.0+EDR. The objective of this project is to improve interoperability between Bluetooth devices, but it’s the speed improvement that’ll capture your interest more than anything else.

In effect, WLAN will be added to the MAC layer, physical layer, and other layers of the existing model of Bluetooth. I still don’t think that it’ll be quite as speedy as a physically wired connection, but that’s a small price to pay for the convenience of wireless. 24Mbps sounds pretty good to me.
