TECHNOLOGY
STE Research on Network Technology is leaded towards the implementation of very efficient communication protocols:
  • Optimization of Network layout and implementation.
  • Correct Data rate, nodes capability, Duty-Cycle and other issues.
  • Correct current consumption optmimization to provide long life cycle of batteries pack.
  • Optimization of cost to market and correct rate between investments and cost of network maintenance.
Price, complexity and current consumption are all mutually related parameters that must be carefully optimized and implemented into a typical M2M wireless RF platform. The actual limit of Standards as Bluetooth or ZigBee is the Protocol complexity of layers: the Program Memory Stack Dimension in Bluetooth is around 250Kbytes where Zigbee is able to provide smaller stack down to 30Kbytes: The key which makes a STE Network concept and implementation a winning solution is the combination between a correct custom design, correct Data Rate, correct current consumption.

NEW PATENTED WOOD LIFE GUARD RF MESH NETWORK SYSTEM.
Active sensor wireless operating system for fire protection and monitoring in wood and forest areas.
Every year 45.000 forest fires burn out in Europe. Between 1989 and 1993 2.6 million hectares of woodland were destroyed by fire in the Mediterranean area; STE, in cooperation with Politecnico di Milano - Technology Transfer Office, has developed new Patented RF application to provide activity of Dynamic Fire Monitoring Detection by means of SRD Low cost.

SVT27
New compact ceramic layer SVT27 SAW Tx.
433,92 MHz OOK “SAW868.35 MHz OOK “SAW” TX ceramic design

The SVT2x is a new concept design series which combines a new “SAW” stabilized circuit design and hybrid ceramic
construction to achieve high stability improved
performances. “A” version is for “OOK”
modulation while “S” version employes a gaussian shaped fast data rate “ASK” modulation.
The SV ceramic layer new design is the innovative approach STE offer on the RF wireless market of SRD: full reliability, stability over temperature range, reduction of mechanical stress are some of the advantages STE launch on the market with the new SV line of SRD low cost ceramic modules.
