SUMMARY Triggered by the explosion of mobile traffic, 5G cellular network requires evolution to increase the system rate 1000 times higher than the current systems in 10 years. Motivated by this common problem, this paper studies to integrate mm-wave access into current cellular networks as multi-band heterogeneous networks to exploit the ultra-wideband(More)
Mobile data traffic has been increasing at a rapid pace over the past few years due to the rise of both smartphones and tablets. To accommodate such a huge traffic volume in cellular systems, it is imperative to reduce cell size to increase system capacity. To reduce cell size, the main issue confronting mobile network operators is system cost to provide(More)
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(More)
– Broadband fixed wireless access (BFWA) networks with Multipoint-to-Multipoint (MP-MP) systems of mesh topology have recently been considered as a promising approach to realize high quality and high performance networks. Needless to say, it is of prime importance to adopt an effective frequency assignment method suitable for MP-MP systems in order to make(More)
