چکیده
This paper gives comprehensive description of a broadband communication system using the 60 GHz frequency band. We describe the channel and its inherent problems such as interference situations and body shadowing. We introduce the use of Virtual Frequency Networks and multiple receiving antennas in order to solve these problems resulting in an overlapping cellular architecture. We explain how the diversity of the channel can be used to increase reliability and performance. Finally, we simulate the link performance of a VCN using two receiving antennas for a set of OFDM parameters.

Performance of 60 GHz Virtual Cellular Networks Using Multiple Receiving Antennas
Virtual Cellular Networks (VCN) are an attractive type of adaptive wireless communication architecture for propagationand coverage-limited environments. In this paper, we investigate the advantages of combining a VCN and multiple receiving antennas for the downlink resulting in a MIMO system. Several ways to combine the signals with different levels of complexity are presented. In the most comp...

متن کاملInterference Mitigation in 60 GHz Wireless Local Area Networks
Due to the small-scale variations of the signal in a 60 GHz wireless network, interference situations can become an important issue. In this paper, we introduce two different ways of designing a 60 GHz wireless network. The first approach is using a beam forming that will minimize the interference, the second is using virtual cells in which different APs are sending the same signal to the termi...
متن کاملImpact of shadow fading in a mm-wave band wireless network
The interest in using higher frequency bands for high data rate wireless communication is increasing. Large unlicensed bandwidths are available specifically around 60 GHz. At this frequency, the propagation characteristics allow small cells and efficient frequency reuse. However, wireless communication at 60 GHz is mainly limited to Line-of-Sight (LOS), due to the high absorption loss of most m...
متن کاملTransmit Power Efficiency of Multi-Hop MRC Diversity for a DS-CDMA Virtual Cellular Network
In virtual cellular network (VCN), proposed for high-speed packet mobile communications, the signal transmitted from a mobile terminal is received by wireless ports distributed in each virtual cell and relayed to the central port that acts as a gateway to the core network. In this paper, multi-hop maximal ratio combining (MHMRC) diversity is presented for the VCN to reduce the transmit power wh...
