RF SW2.4-MED - The Wireless standard for medical equipment

Low energy consumption, rapid connection times, high availability:
These are the key advantages of RF SW2.4-MED »steute Wireless« technology.

The frequency band is subdivided into 32 channels.

Significantly lower power consumption – shorter connection times

The system is subdivided into 32 channels and works on the globally accessible 2.4 GHz waveband. Signal transmission is bidirectional and takes less than 20 ms. At max. 25 mA its power consumption is up to 60 % lower than for other radio standards. In »sleep mode« the system has a power consumption of just 6 μA. It is activated by a switching function, and the radio data connection is built up in less than 200 ms (a typical time is 70 to 100 ms). Users do not notice any difference, but profit from a significantly longer battery life.

As a result of the low power consumption very long battery lifespans can be reached by using merchantable alkaline batteries. As an alternative a rechargeable battery pack is also available.

For foot and hand controls

Nearly all foot and hand controls from steute Meditec can be optionally equipped with steute´s wireless technology. Instead of a cable connection, a compact radio module with integrated antenna is fitted inside the switch, which then communicates with a corresponding receiver belonging to the medical device. The receiver can be designed either as a printed circuit board for complete integration inside the medical device or as a unit in a separate external enclosure. In both cases the receiver interface is adapted to suit the requirements of the customer.

The RF SW2.4-MED radio standard, as well as all the switching devices and modules which use it, conform to the relevant directives for medical equipment as a matter of course.

Transmitter and receiver change channels synchronously.
