Agencia Espacial Española. The Agencia Espacial Española (AEE; [3] Spanish Space Agency) is an agency of the Spanish government responsible for the Spanish space program. The agency was officially announced on 27 May 2021 [4][5] and it became operational in 20 April 2023. [6][7] This new agency aims to group in a single body all the space ...
Antenna diversity. Antenna diversity, also known as space diversity or spatial diversity, is any one of several wireless diversity schemes that uses two or more antennas to improve the quality and reliability of a wireless link. Often, especially in urban and indoor environments, there is no clear line-of-sight (LOS) between transmitter and ...
Medium access control. v. t. e. Spatial multiplexing. 2xSMX or STC+2xMRC. Spatial multiplexing or space-division multiplexing (SM, SDM or SMX) is a multiplexing technique in MIMO wireless communication, fiber-optic communication and other communications technologies used to transmit independent channels separated in space.
The interplanetary Internet is a conceived computer network in space, consisting of a set of network nodes that can communicate with each other. [1][2] These nodes are the planet's orbiters and landers, and the Earth ground stations. For example, the orbiters collect the scientific data from the Curiosity rover on Mars through near-Mars ...
Spatial computing is any of various human–computer interaction techniques that are perceived by users as taking place in the real world, in and around their natural bodies and physical environments, instead of constrained to and perceptually behind computer screens. This concept inverts the long-standing practice of teaching people to ...
Spacetime wave packets. A Spacetime wave packet is a spatial-temporal light structure with a one-to-one correlation between spatial and temporal frequencies. [1] In particular, their group velocity in free space can be controlled arbitrarily from sub-luminal to super-luminal speeds without needing to control the dispersion of the medium it is ...
Spatial Reuse Protocol. Spatial Reuse Protocol is a networking protocol developed by Cisco. It is a link layer protocol for ring-based packet internetworking that is commonly used in optical fiber ring networks. Ideas from the protocol are reflected in parts of the IEEE 802.17 Resilient Packet Ring (RPR) standard.
