Adaptive radio resource management in a sectored cell for broadband wireless access systems
(2010)In this work, we analyze the performance of a multi-user sectored MIMO/OFDMA system under the limited feedback constraint. Dynamic radio resource management methods are used to a reuse-one sectorized cell in order to reduce ... -
Downlink multi-user transmission for higher user speeds in IEEE 802.16m
(2009)A dynamic resource allocation algorithm with beam steering is evaluated for providing broadband wireless access to mobile users of the emerging IEEE 802.16m air interface standard. Thanks to our design, the coverage area ... -
Enabling crowd-sourced mobile Internet access
(2014)Crowd-sourced mobile Internet access services enable mobile users to connect with each other and share their Internet connections. This is a promising solution for addressing users' increasing needs for ubiquitous connectivity ... -
Estimating downlink throughput from end-user measurements in mobile broadband networks
(2019)In recent years, Downlink (DL)throughput estimation in Mobile Broadband (MBB)networks has gained immense popularity and it is expected to become a vital component of the upcoming fifth generation (5G)systems. Plentiful ... -
Large scale “speedtest” experimentation in Mobile Broadband Networks
(2021)Characterizing and evaluating the performance of Mobile Broadband (MBB) networks is a vital need for today's societies. Testbed-based measurements are of great significance in this context, since they allow for controlled ... -
On the use of distributed directive antenna arrays in mobile OFDMA networks
(2011)Distributed Omni Antenna Systems (OASs) have been proposed to increase the capacity of Broadband Wireless Access (BWA) systems. We investigate the extension of such systems by employing distributed Directive Antenna Arrays ... -
Packet reordering effects on the subjective quality of broadband digital television
(2006)Several assessment sessions involving human observers were conducted on the output of a laboratory broadband digital television system to examine how packet reordering could affect the audiovisual subjective quality. Besides ... -
Pricing the last mile: Data capping for residential broadband
(2014)In recent years, ISPs in mature residential broadband markets have been moving away from flat-rate pricing schemes to ones that involve usage limits (or ?data caps). These changes have led to a lively debate about the ...
