Benefits of using a RadioControlli module
RadioControlli is an Italian supplier  with 30 years of experience in the radiofrequency and wireless  field.  The catalog includes standard radio modules (transmitter, receiver ASK/FSK), miniaturized radio modules (SMD mounting) and modules that can be used in the IoT applications.
“Why to use a RadioControlli’s module?” Because it is a self-contained subsystem that utilizes a standard IC and includes several components required to realize a fully functioning Radiofrequency solution. These types of modules can include crystall oscillator, filters, inductors, capacitors, an antenna connection circuit, and a RF shield.  These modules are calibrated, they are all tested  and certified to the required standard (CE or FCC) .  We can recap all the benefits of a RadioControlli module in one sentence :    "Time-to-Market Reduction".
Using a RadioControlli’s module , the final device manufacturer can take products to market faster, so  the manufacturer has more time to develop more functions for the final product;  besides this process minimize the development's costs.
The activity of RF design is described by many as “black magic activity” because it is something that is impenetrable to all, but it is foremost for practitioners with a lot of expertise.  To build a RF design, starting from a single IC, a good RF design expertise is required.
Not every electronics companies are able to make investments in research and development on the activities of RF projects. For this reason the use of RadioControlli’s module avoids a series of technical problems of functionality and development costs.
Using a RadioControlli’s module can reduce the risk associated with implementing RF functionality in a device.  There are no more risk about the testing, design,manufacture, or certification of the RF functions.
Furthermore, the complexity of the manufacture is reduced; it is no more indispensable  to manage many single components but only a simple single object (PCB standard based).
The module is already certified, so there is no need to re-test the new design if Using a pre-certified module.
