New AI can Predict Micronutrient Deficiency from Space
Micronutrient deficiencies are serious and afflict over 2 billion people around the world, including 340 million children. These deficiencies have fatal health consequences, but early diagnosis for effective treatment is costly and requires time-consuming blood draws and lab tests. However,…
First African Rural Satellite Launch
OneWeb, a global communications company with a mission to bring connectivity to everyone, everywhere, has announced the successful launch of its first six broadband satellites aboard a Soyuz launch vehicle from the Guiana Space Center in Kourou, French Guiana. The…
MIT’s Solve 2017 Problem Solving Global challenges
Solve has launched its new challenges for 2017, which is a good base for wireless sensor network practitioners, researchers and IoT experts to showcase why the future belongs to us. According to MIT President Rafael Reif at Solve at MIT…
Satellite Internet- Rudiments to Africa’s Advancement and Development
The Sub-Saharan Africa according to Commonwealth Telecommunications Organisation has succeeded in the last decade in bringing voice services within the reach of some three quarters of the population, but the vast majority of the region is falling further behind the…
Wireless Sensor Network Node with REST Advantages: CoAP Protocol
In this article, the new Constrained Access Protocol (CoAP) will be introduced and analysed for its fitness for purpose in constrained environments such as wireless sensor nodes. Iain Learmonth a member of the Electronics Research Group at the University of…
Wireless Sensor Network Node with REST Advantages: HTTP Protocol
Platforms such as wireless sensor nodes are typically quite constrained in the amount of processing power, memory and battery power available. Whilst 6LoWPAN has enabled these devices to have IPv6 connectivity, the protocols that are typically deployed on top of…
Radio Propagation Modelling
Why is it needed? •To predict coverage between nodes in a wireless network •Path loss is different from environment to environment, e.g., in-building is different to outdoors. •Knowledge of path loss enables system parameters to be defined, e.g.,transmit power, receiver…
Remote Sensing and Satellite
Communication that involves the use of an active or passive satellite to extend the range of a communications, radio, television, or other transmitter by returning signals to earth from an orbiting satellite. For example, researchers like Prof Gorry Fairhurst of…
