Due to the centralized architecture of current cellular networks, the wireless link capacity as well as the bandwidth of the radio access and backhaul networks cannot practically cope with the exponential growth of mobile traffic. In order to meet this challenge, researches on the fifth generation ...
In contrast, we describe why a small cell architecture is amenable for cloudlet deployments. Our experience from operating a small cell testbed in licensed frequencies matches that reported by equipment vendors. The applications we care about require high throughput and low latency. In a...
Power Minimization Based Resource Allocation for Interference Mitigation in OFDMA Femtocell Networks With the introduction of femtocells, cellular networks are moving from the conventional centralized network architecture to a distributed one, where each n...

Extensive performance tests were conducted to evaluate the performance of a two-tier system and compare its throughput...
Overall Cellular Network Architecture Subscribers gain access to acellular networkvia radio signals enabled by aradio access network, as shown inFigure 11.1. The radio access network is connected to the wireline portion of the network, also called thecore network. Core network functions include servici...

To reduce the latency for X2-based handover requests, an edge cloud infrastructure has been also developed to provide high-computing for dedicated controllers at the edge of a cellular network. The proposed system is also compared with the traditional 3GPP architecture and other works in the ...
In this paper, we propose the Unified Cellular and Ad-Hoc Network (UCAN) architecture for enhancing cell throughput, while maintaining fairness. In UCAN, a mobile client has both 3G cellular link and IEEE 802.11-based peer-to-peer links. The 3G base station forwards packets for destination ...
Semtechmade it possible for us to stay in the community without constantly beingat the police department, doing reports, managing things that we can now do in amobile environment. Steve Reeves Chief North Platte Police Department, Nebraska
These applications have extremely demanding connectivity requirements and require very accurate indoor positioning and distinct architecture and security attributes. Industrial Automation IoT reinforced by Critical IoT connectivity is the key enabler for the full digitalization of Industry 4.0 for the world'...
