The IBM Enhanced Performance Wireless Keyboard and Optical Mouse use a 2.4 GHz R/F technology that does not interfere with Bluetooth or Wireless LANs. This product offers a 10-meter range. You can use it in large conference rooms together with a projector and in many other environments. Another benefit of this product is its ease of use. Unlike other wireless products that demand extensive setup, the IBM Enhanced Performance Wireless Keyboard only requires a driver install to begin operating. This keyboard has the same layout as the IBM Enhanced Performance USB Keyboard, which allows you to complete your computing tasks faster, more efficiently, and comfortably. Seven reprogrammable hot keys open programs, documents, and Web sites.
