Wize technology
Wize technology is a low-power wide-area network technology using the 169 MHz radio frequency. It was created by the Wize Alliance in 2017. Derived from the European Standard Wireless M-Bus, it has mainly been used by utility companies for smart metering infrastructures (AMI) for gas, water and electricity but is equally open to other applications in industry and 'Smart City' spaces.
The 169 MHz radio frequency band (169.4 - 169.8125 MHz more precisely), formerly known as ERMES band, was historically used by pager type services.
When this service ended, the European Conference of Postal and Telecommunications Administrations (CEPT) and its Electronic Communications Committee (ECC) decided in 2005 to allocate this frequency for a number of new use cases, including remote meter reading. The low value of the frequency, as well as the potential to transmit at up to 500 mW, makes this band a high-performance technical solution for remote meter reading taking into account the difficult radio access conditions (e.g. deep inside a building) and the necessity to be battery-powered for a long period of time (up to 20 years).
The ISM 169 MHz radio frequency spectrum is open and royalty-free in Europe, working as a license-free band for Short-range devices, with the common spectrum occupancy restrictions these shared spectrum have.
In 2005, Suez, a private water utility, developed an AMI infrastructure based on the 169 MHz frequency to run smart water metering deployments across Europe, mainly in France, Spain and Portugal.
In 2011, Malta's Water Services Corporation (WSC) adopted the 169 MHz frequency band for its smart water metering project, becoming the first country in the world to build a nationwide smart grid within a fully integrated water system.
The EN13757-4 European standard is part of a metering standard suite managed by the CEN TC294 technical committee. The CEN TC294 standardizes communication for gas, water and heat meters as well as for heat cost allocators. EN13757-4 defines the wireless low level interface of this standard, including physical and MAC layers. This standard includes a long list of variants.
In 2012, the emergence of the EN13757-4/N2 variant within the CEN TC294 technical committee constituted a turning point.
