2015 Celtic Event demonstration (April 28th-29th 2015, Vienna)

 

Demo 1: Connectivity Management Platform Using Multiple AttributeDecision Making in Heterogeneous Networks (AVEA)

Mobile operators are thus looking forcost-effective solutions to overcome the capacity bottlenecks especially inhigh contention traffic scenarios. Offloading a portion of the mobile datatraffic to Wi-Fi networks is a promising solution to overcome the capacitybottleneck. However, thereby Wi-Fi networks may get easily congested as well. Acentralized connectivity management mechanism can be used to solve thisdilemma. In this demo, a novel centrally controlled Wi-Fi offloading platformfor heterogeneous wireless networks is presented. For a given user, acentralized management server collects information regarding the quality ofservice and experience from all accessible data networks, then selects the datanetwork that maximizes the overall system performance, finally the decision issent to the application on the mobile phone for execution. The intelligentdecision process uses an algorithm that is shown to be robust and also flexibleto adapt to the needs of different mobile operators.

 

Demo 2: Radio fingerprint positioning demo(MAGISTER / ECE)

Coverage measurements with detailed locationinformation are an important asset in self-optimization of wireless networks.When correlating location and coverage 3G/LTE measurements with coverage WLAN measurements i) thepositioning accuracy can be significantly improved and ii) knowledge aboutjoint coverage of heterogeneous 3G/4G/WLAN networks can be obtained. However,currently, there exists no standardized method to combine 3G/4G measurementswith WLAN measurements. In this demo, LTE and WLAN radio fingerprintpositioning accuracy is visualized utilizing field measurements from commercialLTE network. The demo tracks several mobile users showing their exact andestimated location on top of a map utilizing novel architecture that enablescombining MDT 3G/4G and WLAN fingerprint measurements. Applications: Inaddition to provides a convenient and novel way of visualizing the content ofMDT 3G/4G trace records, this approach is valuable for network vendors andoperators who are keen on automating the collection of radio coveragemeasurements for improving their radio fingerprint positioning capabilities.

 

Demo 3: Dual band / dual access antenna exhibit (CEA)

Integration of small cell base stations tourban environment requires a miniaturization effort compared to regular basestations. In addition, increasing base stations capacity is a hot topic thatcan be handled thanks to Carrier Aggregation (CA) which consists insimultaneously using several carriers (within the same band or not). CEA activedual band / dual access antenna design, covering 2100 and 800 MHz LTE bands,has been optimized to take into account these requirements. Since the antennasize increases with its bandwidth, the antenna system bandwidth has beenreduced as far as possible, to only cover the required bandwidth for a given CAconfiguration. Frequency agility has been introduced to make the antenna systemcompatible with a subset of CA configurations recommended by the standards.This bandwidth reduction has led to a miniaturization of the antenna systemwithout degrading its performance.
