In this paper, we propose a new technique for the future fifth generation\ncellular network wireless backhauling. We show that hundreds of bits per second\nper Hertz (bits per second per Hz) of spectral efficiency can be attained at a\nhigh carrier frequency (such as 26 GHz) between large antenna arrays deployed\nalong structures (such as lamp posts) that are close and roughly parallel to\neach other. Hundreds of data streams are spatially multiplexed through a short\nrange and line of sight massive multiple input massive multiple output\npropagation channel thanks to a new low complexity spatial multiplexing scheme,\ncalled block discrete Fourier transform based spatial multiplexing with maximum\nratio transmission. Its performance in real and existing environments is\nassessed using accurate ray-tracing tools and antenna models. In the best\nsimulated scenario, 1.6 kbits per second per Hz of spectral efficiency is\nattained, corresponding to 80% of Singular Value Decomposition performance,\nwith a transmitter and a receiver that are 200 and 10,000 times less complex,\nrespectively.\n
