| 520 | |a The rapid proliferation of wireless communication devices and the emergence of a variety of new applications have triggered investigations into next-generation mobile broadband systems, i.e. 5G. Legacy 2G-4G systems covering large areas were envisioned to serve both indoor and outdoor environments. However, in the 5G era, 80 percent of all traffic is expected to be generated indoors. Hence, the current approach of macrocell mobile networks, where there is no differentiation between indoors and outdoors, needs to be reconsidered. We envision 60 GHz mmWave picocell architecture to support highspeed indoor and hotspot communications. We envisage the 5G indoor network as a combination of, and interplay between, 2.4/5 GHz having robust coverage and 60 GHz links offering a high data rate. This requires intelligent coordination and cooperation. We propose a 60 GHz picocellular network architecture, called CogCell, leveraging ubiquitous WiFi. We propose to use 60 GHz for the data plane and 2.4/5GHz for the control plane. The hybrid network architecture considers an opportunistic fall-back to 2.4/5 GHz in case of poor connectivity in the 60 GHz domain. Further, to avoid the frequent re-beamforming in 60 GHz directional links due to mobility, we propose a cognitive module, a sensor- assisted intelligent beam switching procedure, that reduces communication overhead. We believe that the CogCell concept will help future indoor communications and possibly outdoor hotspots, where mobile stations and access points collaborate with each other to improve the user experience. | ||

CogCell: cognitive interplay between 60 GHz picocells and 2.4/5 GHz hotspots in the 5G era |
| abstract |
The rapid proliferation of wireless communication devices and the emergence of a variety of new applications have triggered investigations into next-generation mobile broadband systems, i.e. 5G. Legacy 2G-4G systems covering large areas were envisioned to serve both indoor and outdoor environments. However, in the 5G era, 80 percent of all traffic is expected to be generated indoors. Hence, the current approach of macrocell mobile networks, where there is no differentiation between indoors and outdoors, needs to be reconsidered. We envision 60 GHz mmWave picocell architecture to support highspeed indoor and hotspot communications. We envisage the 5G indoor network as a combination of, and interplay between, 2.4/5 GHz having robust coverage and 60 GHz links offering a high data rate. This requires intelligent coordination and cooperation. We propose a 60 GHz picocellular network architecture, called CogCell, leveraging ubiquitous WiFi. We propose to use 60 GHz for the data plane and 2.4/5GHz for the control plane. The hybrid network architecture considers an opportunistic fall-back to 2.4/5 GHz in case of poor connectivity in the 60 GHz domain. Further, to avoid the frequent re-beamforming in 60 GHz directional links due to mobility, we propose a cognitive module, a sensor- assisted intelligent beam switching procedure, that reduces communication overhead. We believe that the CogCell concept will help future indoor communications and possibly outdoor hotspots, where mobile stations and access points collaborate with each other to improve the user experience. |

Further, to avoid the frequent re-beamforming in 60 GHz directional links due to mobility, we propose a cognitive module, a sensor- assisted intelligent beam switching procedure, that reduces communication overhead. We believe that the CogCell concept will help future indoor communications and possibly outdoor hotspots, where mobile stations and access points collaborate with each other to improve the user experience. |

Legacy 2G-4G systems covering large areas were envisioned to serve both indoor and outdoor environments. However, in the 5G era, 80 percent of all traffic is expected to be generated indoors. Hence, the current approach of macrocell mobile networks, where there is no differentiation between indoors and outdoors, needs to be reconsidered. We envision 60 GHz mmWave picocell architecture to support highspeed indoor and hotspot communications. We envisage the 5G indoor network as a combination of, and interplay between, 2.4/5 GHz having robust coverage and 60 GHz links offering a high data rate. This requires intelligent coordination and cooperation. We propose a 60 GHz picocellular network architecture, called CogCell, leveraging ubiquitous WiFi. We propose to use 60 GHz for the data plane and 2.4/5GHz for the control plane. The hybrid network architecture considers an opportunistic fall-back to 2.4/5 GHz in case of poor connectivity in the 60 GHz domain. Further, to avoid the frequent re-beamforming in 60 GHz directional links due to mobility, we propose a cognitive module, a sensor- assisted intelligent beam switching procedure, that reduces communication overhead. We believe that the CogCell concept will help future indoor communications and possibly outdoor hotspots, where mobile stations and access points collaborate with each other to improve the user experience.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">millimetre wave devices</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">legacy 2G-4G systems</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">IEEE 802.11 Standards</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">CogCell</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Array signal processing</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">frequency 2.4 GHz</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">indoor environment</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">control plane</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">macrocell mobile networks</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">frequency 5 GHz</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">cognitive module</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">picocellular radio</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">outdoor environment</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">ubiquitous WiFi</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">indoor radio</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">wireless sensor networks</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">millimetre wave picocellular network architecture</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">telecommunication traffic</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">hotspot communication</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">mobility management (mobile radio)</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">cognitive radio</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">communication overhead reduction</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">data plane</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Computer architecture</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">indoor communication</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">mobile computing</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">access points</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">broadband networks</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">wireless LAN</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">wireless communication devices</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">frequency 60 GHz</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">opportunistic fall-back</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">next-generation mobile broadband systems</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">next generation networks</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">user experience improvement</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">5G mobile communication</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">sensor-assisted intelligent beam switching procedure</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">mobile stations</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Technological planning</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Wireless communication systems</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Research</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Mobile communication systems</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Engineering research</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Prasad, R.
