WIRELESS DATA NETWORK [14 records]

Record 1 2025-01-24

English

Subject field(s)
  • Data Transmission
  • Internet and Telematics
CONT

Description of Modem Signals. ... Request to Send (RTS). ... this signal is generally used to indicate that the computer is prepared to receive data from the modem (it can also be used in half-duplex communication to request permission to transmit, hence the name).

CONT

What is request to send(RTS) ? RTS is a pivotal concept in computer networking. It functions as a digital protocol ensuring efficient data transmission, particularly in wireless communication. When a device wants to send data, it initiates an RTS signal, essentially requesting permission to transmit. This preemptive communication helps prevent collisions in shared network spaces, promoting a smoother flow of data. While RTS adds a layer of coordination, it's especially crucial in crowded network environments, where simultaneous transmissions are likely.

OBS

Ready to Receive; Ready to Send: These designations do not appear in either the IEEE 802.11 or the RS-232 standards.

English

Subject field(s)
  • Radar, Radio Guidance and Goniometry
  • Weather Stations and Meteorological Instruments and Equipment
CONT

Electromagnetic interference is one of the main challenges in weather radar data quality assurance. In Italy, as in most European countries, C-band weather radars are continuously dealing with interferences caused by RLAN [radio local area network] and WLAN [wireless local area network], which share the same frequency band as weather radars.

Domaine(s)
  • Radar, radioguidage et radiogoniométrie
  • Stations, instruments et équipements météorologiques
CONT

Un radar météorologique en bande C comporte une antenne parabolique qui émet un faisceau d'ondes électromagnétiques dans la bande de fréquences des 5 GHz [gigahertz]. En se déplaçant dans les plans vertical et horizontal, le radar scrute l'espace environnant. Il a une portée d'environ 100 km. Les ondes émises ont la propriété de se refléter sur les gouttes de pluie, les grêlons et la neige. Leurs échos, qui correspondent à une infime partie de l'onde reçue, sont reçus par le radar qui les analyse grâce à sa grande sensibilité. Le radar en déduit la distance qui le sépare des gouttes et localise ainsi les zones de précipitations.

English

Subject field(s)
  • Radiotelephony
CONT

Wireless networks are proliferating rapidly, going digital and harnessing "intelligent network" technology to locate and identify roaming subscribers and to customize the services they receive. An intelligent network consists of a distributed signaling network of switches, databases and dedicated computer servers that is separate from, yet intimately connected to, the transport networks on which subscriber's voice calls and data actually flow. This architectural framework, which has been refined over the past 30 years to support such services as 800-number calling, caller identification and "911, "will soon make personalized communications services as portable as a pocket telephone.

French

Domaine(s)
  • Radiotéléphonie
CONT

La croissance du marché des radio-communications a intensifié la pression [...] sur les opérateurs pour qu'ils utilisent les fréquences plus efficacement en adoptant des techniques numériques.

OBS

Les réseaux radiotéléphoniques, de plus en plus nombreux, deviennent numériques et «intelligents», afin de localiser et d'identifier les abonnés mobiles et de personnaliser les services qui leur sont proposés. Les réseaux intelligents sont composés de commutateurs, de bases de données et de serveurs spécialisés, en plus des réseaux de transport où transitent les appels et les données des abonnés. Cette architecture, perfectionnée tout au long des 30 dernières années afin d'inclure des services tels que les numéros verts et l'identification du correspondant, débouchera bientôt sur des systèmes de communication personnalisés aussi petits que les téléphones portatifs.
