Internet of things: come e perché

Se ne parla da molti anni. E’ una di quelle cose che sembrano consumarsi negli annunci. Ma le precondizioni per un’accelerazione dell’internet of things stanno maturando tutte insieme, sostiene OpenMind.

A number of significant technology changes have come together to enable the rise of the IoT. These include the following.

Cheap sensors – Sensor prices have dropped to an average 60 cents from $1.30 in the past 10 years.
Cheap bandwidth – The cost of bandwidth has also declined precipitously, by a factor of nearly 40X over the past 10 years.
Cheap processing – Similarly, processing costs have declined by nearly 60X over the past 10 years, enabling more devices to be not just connected, but smart enough to know what to do with all the new data they are generating or receiving.
Smartphones – Smartphones are now becoming the personal gateway to the IoT, serving as a remote control or hub for the connected home, connected car, or the health and fitness devices consumers are increasingly starting to wear.
Ubiquitous wireless coverage – With Wi-Fi coverage now ubiquitous, wireless connectivity is available for free or at a very low cost, given Wi-Fi utilizes unlicensed spectrum and thus does not require monthly access fees to a carrier.
Big data – As the IoT will by definition generate voluminous amounts of unstructured data, the availability of big data analytics is a key enabler.
IPv6 – Most networking equipment now supports IPv6, the newest version of the Internet Protocol (IP) standard that is intended to replace IPv4. IPv4 supports 32-bit addresses, which translates to about 4.3 billion addresses – a number that has become largely exhausted by all the connected devices globally. In contrast, IPv6 can support 128-bit addresses, translating to approximately 3.4 x 1038 addresses – an almost limitless number that can amply handle all conceivable IoT devices.

Per un sistema industriale come quello italiano che produce oggetti più che software la connessione dei prodotti alla rete può risultare particolarmente interessante, generare innovazioni significative e aumentare il valore aggiunto. Tra l’altro i sensori sono una tecnologia che gli italo-francesi di Stm sanno fare con risultati significativi sul mercato. Ma evidentemente si tratta di sviluppare la visione e di testare i prodotti connessi. Le precondizioni sono un generatore di opportunità. E’ probabile che qualcuno le colga. Sarebbe piuttosto importante che tra chi le coglie ci siano anche i produttori italiani.
