“…To extend the communication distance, the beamforming technology which consists of an array antenna with beam steering capability is widely used to obtain higher antenna gain, at the cost of increased power dissipation. A recent publication [40] employs 16 Tx and 16 Rx array structure, demonstrating 4.6 Gbps throughput at 10 m communication distance while dissipating 960 mW in Rx and 1190 mW in Tx excluding the power consumption of the baseband signal processing. In WiGig/IEEE 802.11ad, both SC modulation and OFDM modulation have been adopted, considering various use case scenarios.…”

SUMMARY Millimeter-wave (mmw) frequency bands, especially 60 GHz unlicensed band, are considered as a promising solution for gigabit short range wireless communication systems. IEEE standard 802.11ad, also known as WiGig, is standardized for the usage of the 60 GHz unlicensed band for wireless local area networks (WLANs). By using this mmw WLAN, multi-Gbps rate can be achieved to support bandwidthintensive multimedia applications. Exhaustive search along with beamforming (BF) is usually used to overcome 60 GHz channel propagation loss and accomplish data transmissions in such mmw WLANs. Because of its short range transmission with a high susceptibility to path blocking, multiple number of mmw access points (APs) should be used to fully cover a typical target environment for future high capacity multi-Gbps WLANs. Therefore, coordination among mmw APs is highly needed to overcome packet collisions resulting from un-coordinated exhaustive search BF and to increase total capacity of mmw WLANs. In this paper, we firstly give the current status of mmw WLANs with our developed WiGig AP prototype. Then, we highlight the great need for coordinated transmissions among mmw APs as a key enabler for future high capacity mmw WLANs. Two different types of coordinated mmw WLAN architecture are introduced. One is distributed antenna type architecture to realize centralized coordination, while the other is autonomous coordination with the assistance of legacy Wi-Fi signaling. Moreover, two heterogeneous network (HetNet) architectures are also introduced to efficiently extend the coordinated mmw WLANs to be used for future 5 th Generation (5G) cellular networks. key words: millimeter wave, IEEE802.11ad, coordinated mmw WLAN, 5G cellular networks, heterogeneous networks

“…This is a key enabling technology for the success of Cyber Physical Systems where high speed sensor nodes are used such as radars, cameras, array of detectors and so on. At higher layers of the networking protocol stack our solution can be made compliant with upcoming IEEE 802.11ad wireless networking standard [6,7] (WiFi/WiGig Alliance) that foresees 3 physical layer frequencies at 2.4 GHz, 5 GHz and 60 GHz.

In Cyber Physical Systems there is a growing use of high speed sensors like photo and video camera, radio and light detection and ranging (Radar/Lidar) sensors. Hence Cyber Physical Systems can benefit from the high communication data rate, several Gbps, that can be provided by mm-wave wireless transceivers. At such high frequency the wavelength is few mm and hence the whole transciever including the antenna can be integrated in a single chip. To this aim this paper presents the design of 60 GHz transciever architecture to ensure connection distances up to 10 m and data rate up to 4 Gbps. At 60 GHz there are more than 7 GHz of unlicensed bandwidth (available for free for development of new services). By using a CMOS SOI technology RF, analog and digital baseband circuitry can be integrated in the same chip minimizing noise coupling. Even the antenna is integrated on chip reducing cost and size vs. classic off-chip antenna solutions. Therefore the proposed transciever can enable at physical layer the implementation of low cost nodes for a Cyber Physical System with data rates of several Gbps and with a communication distance suitable for home/office scenarios, or on-board vehicles such as cars, trains, ships, airplanes. Needs of High Speed Wireless Connections in Cyber Physical SystemsCyber Physical Systems are feedback systems where sensing, actuation, and processing is usually distributed among several nodes (Electronic Control Units, Actuator Control units and smart sensors) connected through digital networks, both cabled or wireless [1,2]. Indeed most of today control systems are realized according to a distributed paradigm to improve the scalability and flexibility of the solution, to increase the interoperability of subsystems from different providers/vendors, to reduce the "single point of failure" risk of a centralized approach.A key issue in emerging Cyber Physical Systems is the networking at high speed of all the nodes belonging to the network. In this scenario there is a growing use of high speed sensors like photo and video camera, radio and light detection and ranging (Radar/Lidar) sensors, photo detectors and so on, to increase the knowledge of the environment where the system is operating, and to increase the amount of data acquired and used by the "cyber" part of the system to make a decision/actuation. This increases the need for high speed communications, with wireless connections to avoid wiring harness, beyond 1 Gbps [3][4][5]. Hence at the physical level of a Cyber Physical System there is the need of high speed wireless solutions reaching data rates well beyond the tens of Mbps offered today by Wireless LAN or Bluetooth devices. To this aim some standardization initiatives such as the Wi-Gig alliance have been already started and a new IEEE 802.11ad standard is emerging [6-8].

This paper presents the first large-scale wafer-scale phased-array at 60 GHz with 64-elements spaced )J2 apart and occupying a full reticle area of 2.2x2.2 cm 2 • The transmit array includes high-efficiency on-wafer antennas, 3-bits amplitude and S-bits phase control on each element, and a highly redundant RF distribution network for improved yield. It also includes redundant SPI control and power strips, also for improved yield.The 64-element array results in a half-power beam width of 12.5°in the E-and H-planes, a directivity of 23 dB and scans to +/-55° in the E-and H-planes with near-ideal patterns and a cross-polarization level of <-25 dB. The measured EIRP is 38 dBm at 66 GHz, but this is currently being redone for improved accuracy. To our knowledge, this is the largest single-chip phased array ever developed and paves the way to mm-wave large-scale (1000+ elements) phased-array systems.
