Satellite Gateway and Hub technology trends

Internet access has historically been terrestrial or based on networks, such as fiber or other data cabling that is based on the ground.  Cellular data is another common method of providing internet access. Satellite Internet access is Internet access provided through communication satellites. Satellite connections are often employed in remote …

Software-Defined Networks (SDN) based Satellite Networks

Satellite communication offers a number of advantages over traditional terrestrial point-to-point networks. Satellite networks can cover wide geographic areas and can interconnect remote terrestrial networks (“islands”). In the case of damaged terrestrial networks, satellite links provide an alternative. Satellites have a natural broadcast capability and thus facilitate multicast communication. Finally, …

AI enabled Intelligent Satellite Networks

Satellite communication can provide many benefits and complement terrestrial networks. They can provide service continuity, to provide network access over uncovered and under-covered areas. They can provide backup or service ubiquity, to ameliorate the network availability in cases of temporary outage or destruction of a ground network due to disasters. …

Europe and US launch Quantum testbeds and Quantum loop to catchup China in Quantum Communications Race

The race to conquer the quantum domain is among the most fiercely competitive in today’s world of technology. One important quantum technology is Quantum key distribution (QKD), that establishes highly secure keys between distant parties by using single photons to transmit each bit of the key.   Quantum cryptography is unbreakable …

Co-operative Perception (CP) for Intelligent Transportation Systems (ITS)

Autonomous vehicles (AVs) have received extensive attention in recent years as a rapidly emerging and disruptive technology to improve safety and efficiency of current road transportation systems. Most of the existing and under development AVs rely on local sensors, such as cameras and lidars, to perceive the environment and interact …

Software modem

Conventional modem designs can be termed as ‘fixed-function’ modems ‘ because almost all modem functionality in these modems are implemented in silicon resulting in large die sizes and limited flexibility. As the number and complexity of air interfaces increase, so does the challenge involved in planning, designing, manufacturing, testing and …

Software Defined Network (SDN)

Software-Defined Networking (SDN) is a network architecture approach that enables the network to be intelligently and centrally controlled, or ‘programmed,’ using software applications. This helps operators manage the entire network consistently and holistically, regardless of the underlying network technology.   Software-defined networking (SDN) is the decoupling of the network control logic from the …

Software Defined Radio (SDR) technology

A radio is any kind of device that wirelessly transmits or receives signals in the radio frequency (RF) part of the electromagnetic spectrum to facilitate the communication or transfer of information.   Software-defined radio (SDR) is a radio communication system where components that have been traditionally implemented in hardware (e.g. …

Metamaterial based Antennas for wireless and space communications, GPS, satellites, airplanes and missile seekers

Wireless electronic systems have been relying on dish antennas to send and receive signals. These systems have been widely used where directivity is important and many of those systems work well at a relatively low cost after years of optimization. These dish antennas having a mechanical arm to rotate the …
