WAN Networks

A point-to-point communication is an exclusive air connection link between two systems . It is the easiest and most effective way to provide a wireless connection from one site (or building) to another.

For example, in a telephone call, one phone is connected with another one. What is said by the first caller can only be heard by the other. On the opposite, point-to-multipoint or broadcast connection allow many network nodes to receive information transmitted by one node.

Point to point wireless connection (also called P2P) typically uses directional antennas, and requires an unobstructed line of sight between the two points.

Wi-Fi, short for wireless fidelity, is a wireless networking protocol that allows devices to communicate without being connected together with wires or cables. Based on the IEEE 802.11 network standards, Wi-Fi is commonly used for local area networking (LAN) of devices and Internet access, using short range radio waves.

Used all around the globe, Wi-Fi can also be configured as WAN networks, on larger scale, using essentially repeaters and amplifiers.

Sigfox is a French telecommunications operator created in 2009. It is the very first IoT (Internet of Things) network to have been set up. It currently covers 45 countries in Europe and worldwide.

Sigfox’s service revolutionizes M2M (Machine to Machine communication) with its cellular connectivity offer, it allows devices to communicate with low power on a wide area . The network, which uses UNB (Ultra Narrow Band), allows connected devices to communicate with each other while significantly reducing their energy consumption and price.

With our EASY product range , using Sigfox technology, SEE is able to send information (geolocation, video, audio, temperature, humidity, …) without any distance constraint, directly to your servers. Then, the information stored can then be pushed to platforms allowing data formatting (statistics, curves, alarms…) thanks to PLCs or Callbacks.

LoRa network is a radio telecommunication protocol also known as Long Range. Like SigFox network, it is a technology that allows the connected objects to exchange low data rate and low size data.

LoRa technology mainly plays on energy saving for objects in themselves. It responds to the problems of IoT market by providing, with low consumption, bidirectional links between an object and the collecting network over several kilometres. This also makes it possible to exchange information with devices, not only to receive the information, but also to give it simple commands: activation at a fixed time, system verification, ….

The Global Positioning System ( GPS ) is a satellite-based radionavigation system that receives signals from satellites and determines a position. The network of 24 satellites currently in operation, owned by the United States government, is freely accessible to civilians . It makes it possible to determine the geographical coordinates of any point on the surface of the globe. It can be accurate to within 1 metre.

The operating principle of GPS is based on measuring the distance of a receiver from several satellites. Each satellite emits a signal, which is picked up on Earth by the receiver, thus making it possible to measure very precisely the distance between the transmitter and the receiver thanks to the travel time.

LTE (Long Term Evolution) is the most recent development in mobile telephony standards. LTE networks are cellular networks made up of thousands of radio cells using the same radio frequencies.

The standard is also called “3.9G” because it is close to 4G, but it does not yet meet all the specifications imposed by the International Telecommunication Union (ITU) and the 3GPP for 4G standards, particularly in terms of bandwidth and usable data rates.
