SegaLink

SegaLink is a wireless communication protocol used by Sega for online gaming on its Dreamcast console and certain games on the Sega GameTap service. Developed by Sega, the first telecommunications company to own a game company, it was initially revealed in 1999.

The protocol is based on the IDU (Inductive density Unit) developed by Sony, but uses a different suffix to differentiate it from the company's IrDA ultra. Sega partnered with a variety of companies, including Edgecast Connect, to establish a separation between system functionalities and actual communication software functionality.

Unlike competitors such as Microsoft and Sony, which were using components of the web based architecture to base their products named online service Xbox Live Xbox Live and the PlayStation Network, SegaLink would not distribute game content but rather would function to link Sega hardware and content service. At the time, the SegaLink technology had been in testing and implementation since the Spring of 1997 and the goals have been gradually rolled back.

Some games that supported SegaLink include ChuChu Rocket!, Phantasy Star Online, and Crazy Taxi. The service saw limited adoption and was eventually discontinued.

SegaLink introduced 35 to 80 spheres with 10 VR-chip processors that would enable speed accounted MOSFi in a chip enabling communications and Dynamic ( requires free-range features anymore).
