Signals that can be directed toward a specific point in space exclusively through electronic control. Q: What are phased arrays and why do we need them at mmWave frequencies?Ī: A phased array is an array of antennas which can be used to create a narrow beam of radioĬlose up of the silicon-based millimeterWave phased array antenna module mounted on a test board. However, for 5G to leverage this new mmWave spectrum, new equipment and radio access will be required, including new base station designs that support transmission and reception at these frequencies, and ultimately new smartphones with mmWave wireless capability. This spectrum offers dramatically wider bandwidths for data transmission than have been allocated in previous generations. The millimeter wave (mmWave) frequency spectrum, which lies between the microwave spectrum and infrared spectrum, offers an entirely new source of bandwidth for cellular networks that are being made available for 5G networks. This includes new spectrum below 6GHz, as well as spectrum in higher frequency bands. In order to support increased traffic capacity and to enable the transmission bandwidths needed to support very high data rates, 5G is expected to extend the range of frequencies used for mobile communication. 5G is expected to support data rates that exceed 10Gbps in specific scenarios such as indoor and dense outdoor environments. It is necessary to support soaring mobile data consumption rates driven by ever-expanding consumption of video content, as well as by the Internet of Things and its associated projected billions of connected devices. This group jointly developed a millimeterWave phased array module designed for 5G base station communicationsĪ: Today, we’re on the cusp of a new generation of wireless communications called 5G.

The reported work, which is the result of a two-year collaboration between IBM Research and Ericsson, could help effectively build 5G access infrastructure.īodhi tells us what to expect in the next several years as technological advances move 5G wireless experiments from prototype to a commercial reality.
Today, Bodhi is presenting a paper at the International Solid-State Circuits Conference, announcing the world’s first reported Si-based 5G mmWave phased array antenna module operating at 28GHz. By the time he graduated in 2007, everyone had a mobile phone the technology behind the cell phone fascinated Bodhi, setting his career on a path toward the development of wireless technology and radio frequency integrated circuits. When Bodhisatwa (Bodhi) Sadhu was starting out his undergraduate degree in Electrical and Electronics Engineering at BITS Pilani in India in 2003, students would have to wait in line 30 minutes or more to make calls home on one of the two landline phones on campus. More on the Low Frequency Sensor and MCFR radars can be found on the MEADS International website at. MEADS radars provide detection capacity against maneuverable, low-signature threats such as short- and medium-range ballistic missiles and cruise missiles.Ī formal flight test of the MEADS radars will occur later this year at White Sands Missile Range in New Mexico.Ī video of the MFCR radar in test can be viewed at. Their “plug-and-fight” design allows the radars to act as nodes on integrated air and missile defense networks. The MEADS radars are capable of wideband discrimination and classification, as well as precision tracking. "The MEADS radars offer greater coverage and flexibility, including complete 360-degree defense to protect military sites and civilians against next-generation threats," says Dave Berganini, President, MEADS International. The system is the only transportable air and missile defense radar capable of 360-degree coverage at such ranges. During testing, the two radars were situated more than ten miles apart and repeatedly exhibited 360-degree rotating mode capability while tracking aircraft flying in and out of the airport. The MEADS Low Frequency Sensor is an electronically steered, active array radar capable of 360-degree, extended range coverage, while the MEADS MFCR is a 360-degree X-band, solid-state phased array radar. The Battle Manager then produced corresponding cue search commands for the X-band MFCR, which searched the cued area and set up a dedicated track once the target was acquired.
The UHF Low-Frequency Sensor acquired, tracked, and relayed the location of a small test aircraft to the MEADS Battle Manager. A Medium Extended Air Defense System (MEADS) Low-Frequency Sensor has cued a Multifunction Fire Control Radar (MFCR) in a demonstration at Hancock Airport in Syracuse, N.Y.
