Each technology addresses different uses. Choose the right one for you
Wize technology is a registered trade mark naming a low-power, long-range and bi-directional radio communication that operates around 169 MHz frequencies. Specifically designed to connect hard to access objects (isolated or buried objects), leveraging over ten years’ experience of field deployments, Wize delivers secure information for Internet of Things applications for cities, industrial or tertiary sectors.
Wize technology offers a range of several tens of kilometers in the open field, a good resistance to the phenomenon of attenuation. The technology offers rates of message exchange between 2400 and 6400 bits/s all the while preserving the duration of battery life and limiting the use of bandwidth and therefore collisions.
An industrial technology
Wize technology enables the management of a large number of objects in bi-directional mode and the secure transmissions of an object to the management platforms. The current version is based on the European standard 13757-x, defined by the European Union to accompany the deployment of communicating meters.
This technology is for the usage linked to the Industrial Internet of Things. In other words, it is specially designed to ensure deployments on a territory-wide scale for the city's uses, which require lifetime characteristics and integration in a constrained environment: metering, public lighting, energy management of buildings, smart mobility ...
Less energy, longer lifetime
Although Wize Technology was developed in VHF (very high frequency) 169 MHz, it is modular and works on other close frequency bands. The technology is already proven in many countries in Europe and Africa, it is very effective to deploy a network on a local scale.
With equal range, the attenuation of the low frequencies is smaller, so Wize technology consumes less energy and allows a longer life.
Communications from one object to the gateways are carried out in broadcast mode in both directions, which allows multiple gateways to receive the same message from an object. Therefore, this system increases the performance of the radio solution by providing redundancy and high availability in the system.
Simple deployment requirements
On a territory-wide scale, deployment of the network is simple and fast because the technology requires a minimum of equipment (a communicating object and a concentrator): no repeater system, no pairing or complex programming sensor.
It has very good performances (range, penetration, special redundancy), which have been confirmed in the framework of large-scale field deployments, making it possible to minimize the number of equipment and therefore high points to accommodate them.
Low maintenance conditions
This technology has the ability to have objects communicate that are sufficiently energy-efficient to last a very long time. For example, water and gas communicating meters are powered by battery, the lifetime of which is expected to last 20 years for the most restrictive use.
Since the technology requires only a limited number of equipment, it facilitates the operating and maintenance costs and conditions.
