Toward a Seamless Communication Architecture for In-building Networks at the 60 GHz band

Abstract

This paper addresses the issues of designing an infrastructure to support seamless in-building communication at the 60 GHz band. Recently, the 60 GHz band has received much attention due to its 5 GHz of available spectrum. However, the propagation of signals in this band is strongly hindered by attenuation and line-of-sight requirements. The situation gets worse in the in-building environment where signal propagation is obstructed by physical objects such as walls, furniture etc. In this paper, we present a novel Radio over Fiber (RoF) architecture that is cost-effective and is able to deliver high data-rate of the order of gigabits. To ensure a seamless communication environment at the 60 GHz band, we propose the concept of Extended Cells (EC) in order to create sufficient overlap areas. Finally, we illustrate the effectiveness of the proposed architecture by simulating an in-building network at the 60 GHz band employing the RoF and EC concepts.

Sensor assisted movement identification and prediction for beamformed 60 GHz links

“…A slight displacement in device position/orientation can result in link misalignment. This thesis focuses on the challenge of device movement in 60 GHz networks, which can limit the maximum achievable link quality [3,9,18,20]. Different causes are attributed to link degradation due to device movement:…”

Home networking at 60 GHz: challenges and research issues

“…This approach is based on the novel radio-over-fiber (RoF) technique [12] which requires a low-cost plastic optical fiber infrastructure to be installed in new buildings or retrofitted to existing buildings. As illustrated in Fig.…”

“…With this target in mind, an infrastructure for broadband in-building networks at millimeter-wave GHz band was presented in [12,18]. It is proposed to group multiple adjacent antennas into an extended cell (EC) and to allow the antennas to transmit the same content over the same frequency channel.…”

On-chip micromachined dipole antenna with parasitic radiator for mm-wave wireless systems

“…The 60 GHz band has received much attention in the last few decades where it offers 5 GHz bandwidth [1] which matches the continuous desire of developing small wireless devices that are capable of transmitting data very fast. Thanks to the technology advances, nowadays, devices with dimensions down to the micro and even nanoscale are now fabricated.…”
