60 GHz MAC Standardization: Progress and Way Forward
Communication at mmWave frequencies has been the focus in the recent years.
In this paper, we discuss standardization efforts in 60 GHz short range
communication and the progress therein. We compare the available standards in
terms of network architecture, medium access control mechanisms, physical layer
techniques and several other features. Comparative analysis indicates that IEEE
802.11ad is likely to lead the short-range indoor communication at 60 GHz. We
bring to the fore resolved and unresolved issues pertaining to robust WLAN
connectivity at 60 GHz. Further, we discuss the role of mmWave bands in 5G
communication scenarios and highlight the further efforts required in terms of
research and standardization
Beam Based Stochastic Model of the Coverage Probability in 5G Millimeter Wave Systems
Communications using frequency bands in the millimeter-wave range can play a
key role in future generations of mobile networks. By allowing large bandwidth
allocations, high carrier frequencies will provide high data rates to support
the ever-growing capacity demand. The prevailing challenge at high frequencies
is the mitigation of large path loss and link blockage effects. Highly
directional beams are expected to overcome this challenge. In this paper, we
propose a stochastic model for characterizing beam coverage probability. The
model takes into account both line-of-sight and first-order non-line-of-sight
reflections. We model the scattering environment as a stochastic process and we
derive an analytical expression of the coverage probability for any given beam.
The results derived are validated numerically and compared with simulations to
assess the accuracy of the model
