TECHNICAL CHARACTERISTICS OF SMART CITY PLATFORM READY FOR THE INTERNET OF THINGS
NATIVE AND NETWORK IPV6 PROTOCOL
IPv6 protocol allows end-to-end bi-directional communication between urban objects to create and manage innovative services, with the ability to make decisions and define real-time actions by adapting the services themselves to varying conditions. An IPv6-based solution speaks the language of the Internet: if we were able to connect only PCs 20 years ago and today we are talking about smartphones, tablets and a number of devices, tomorrow the urban IP network will support objects and applications we still do not know.
WIRELESS SUB-GHz & 2.4 / 5 GHz CONNECTIVITY
The narrowband Sub-GHz network is ideal for connecting urban objects (streetlights, counters, traffic lights, parking lots, etc.) that need to transmit limited amounts of data, since it offers the best performance thanks to the perfect outdoor radio propagation. More powerful data applications, such as Wi-Fi or IP cameras, can be supported by the broadband section of the same network. The integration of the two sections into the same urban infrastructure allows to cover the connectivity needs of the city with a single reliable and secure solution, easy to manage and able to provide a satisfactory ROI.
IETF 6LoWPAN PROTOCOL FOR A SOLID MESH NETWORK
The 6LoWPAN protocol supports virtually unlimited extensions, with billions of interconnected objects. It also ensures maximum scalability and is born as a “pure” data transfer protocol, is 100% agnostic to applications and devices. Unlike other protocols, such as ZigBee, it has been designed and developed for industrial wireless networks requiring high levels of reliability and long range coverage as well as the ability to support outdoor sensor networks as well. LoWPAN is optimized for Ultra Low Power devices management and offers the ability to optimize network power consumption and the battery life of individual objects.
OPEN STANDARD, AUTOCONFIGURATION AND AUTHORIZATION
Unlike proprietary systems, IEEE 802.15.4 and IETF 6LoWPAN protocols allow interoperability and allow a large number of devices and applications to communicate with each other. This enables the construction of “future-proof” infrastructures. Both standards offer maximum ease of use experience and a full range of plug & play functionality, including the off-the-sheld ability of self-configuration and self-configuration.
6LWWAN AND POWER LINE COMMUNICATION
In some cases, the radio signal may not be the optimal means of communicating – for example, data transmission between devices placed underground or submerged in the sewer pipelines of the city. By using the existing power grid, it is therefore preferable to use 6LoWPAN devices with integrated Power Line Communication (PLC) technology. The ability to build a single IPv6 / 6LoWPAN network with wireless connectivity and PLC can make a difference, overcoming any physical or infrastructure constraints.
FULL MESH WIRELESS NETWORK
From a physical point of view, a full mesh wireless network is the only possible architecture to enable and support the Internet of Objects in a simple and reliable way. It is the only known mechanism to ensure an efficient connection between a device and any other achievable remote object. Thanks to this feature, the full mesh wireless network offers multiple alternative paths for connecting two objects, plus self-configuration and self-tuning capabilities to overcome possible obstacles, interference or technical problems with the utmost reliability and flexibility.
IPv6 PROTOCOL FOR MULTIFUNCTIONAL AND AGNOSTIC PLATFORM
The proliferation of objects connected to the Internet and always operational requires network infrastructures to simultaneously support multiple functions and be agnostic to services and applications. This is particularly true for the Internet of Things, which sees the network as the infrastructure that enables communication between billions of devices scattered around cities and even worn by users – think of the latest wearable technologies or latest medical devices generation. Only an IPv6 network can meet the present and future needs of a Smart City
