Pressesc reports about multi-gigabit wireless technology capable of achieving 15 Gbps, using of extremely high radio frequencies (RF) to achieve broad bandwidth and high data transmission rates over short distances, stating that it will be available within 3 years.

Developed by scientists at Georgia Electronic Design Center (GEDC), the research focuses on RF frequencies around the currently unlicenced free-for-all 60 gigahertz (GHz) range, having already achieved wireless data-transfer rates of 15 gigabits per second (Gbps) at a distance of 1 meter, 10 Gbps at 2 meters and 5 Gbps at 5 meters.

They are seeking to preserve backward compatibility with the WiFi standard, placing special emphasis on implementing an RF concept called single-input-single-output (SISO) / multiple-input-multiple-output (MIMO), which enables ultra-high data throughput while preserving backward compatibility with WLAN 802.11, the WiFi standard.

The transmitted power is extremely low, in the vicinity of 10 milliwatts or less and the 60 GHz frequency is stopped by human skin and cannot penetrate the body, thus the technology poses no health threats.

The challenges of enabling a 60 GHz Multi-Gbps radio are CMOS based 60 GHz MMIC design, low power and compact single chip radio, low power ultra-high speed modem, low cost, low loss, compact, 3D packaging, high efficiency, high gain antenna.

The IEEE, the leading international association of electrical engineers, is also weighing a 60 GHz standard, to be called 802.15.3C.
