Cingular used a trade show in Las Vegas this week to transmit a wireless call using a device capable of hitting 3.6 megabits per second.

Cingular said it became the first wireless carrier to achieve that mark.

The demonstration included high-speed downlink packet access device (HSDPA), a modem card from Option Wireless and a chipset from Qualcomm. The call was delivered over Cingular’s 3G network.

“We continuously strive to enhance our customers’ wireless experience, using technology to deliver the most advanced data services and the highest quality voice services available,” said Kris Rinne, chief technology officer for Cingular Wireless. “The flexibility of using HSDPA in our network gives us the ability to significantly increase data connection speeds as the market demands.”

Cingular offers HSDPA service with downlink speeds of 400 to 600 kilobits per second with bursts to over one megabit per second in Las Vegas and 15 other markets.
