Willcom develops "Ultra low power PHS chipset" that can wait for 10 years or more

Although PHS featuring low power consumption etc. compared with mobile phones, WILLCOM newly "Ultra low power PHS chipsetWe are expressing that we will develop "

The chipset that realized a surprisingly long life expectation that it will be able to wait for more than 10 years with a battery can be expected to be useful in fields such as public infrastructure.

Details are as below.
WILLCOM | Battery (2,400 mA / 3 V) * 1 An intention to develop "ultra-low power PHS chipset" to realize a telemetering device that operates over three years with more than 10 years

According to Wilcom 's press release, the company announced the "Ultra Low Power PHS Chipset" optimized for the communication infrastructure of the Machine to Machine (M2M) solution by reducing the current consumption of the existing PHS baseband IC, It seems to cooperate and develop.

In recent years, with the advancement of information communication, the "Internet of Things (IoT)" in which appliances and devices that had no communication function so far connected to the network, such as home appliances, automobiles, and vending machines, are developing Although there is, on the other hand, consideration about power consumption when connecting a huge number of things to the network was a challenge.

Therefore, as one solution to this problem, WILLCOM reduces the current consumption of both PHS baseband IC at the time of standby and at the time of wireless operation, and by optimizing the network side, three cells of 2400 mA / 3 V We will develop "ultra-low power PHS chipset" to realize a device enabling waiting for over 10 years.

"Ultra-low power PHS chipset" makes it possible to install communication functions to devices and devices that have been difficult to achieve due to the problem of power consumption until now, and furthermore, standard "UART"When"GPIOBecause it carries the temperature and humidity management, water level measurement, weather station, location information terminal, burglar alarm / crime prevention equipment, sensors and monitoring is expected to be expected.

The usage image looks something like this. Currently, PHS is adopted for meter reading of LP gas and electric power, copying number of copying machine, inventory information management of vending machine, parking, certification photo machine, elevator, car navigation etc.


Moreover, in order to correspond also to the standard interface "U bus" of meter with communication function standardized by NPO corporation "Telemetering Promotion Council", ultra low consumption of battery driven type in city gas, LP gas, water service It is said that it will be possible to use it for power telemetering communication system, and commercialization planned in April 2012.

Next-generation vending machine compatible with WiMAXAlthough there is definitely an advantage obtained by incorporating a communication line into equipment as in the past, as it has been commercialized by "Ultra Low Power PHS Chipset", onceConcept terminal WILLCOM exhibited at Wireless Japan 2009Would not it be interesting if the model like this would be realized?
