Abstract
A gateway architecture able to meet the challenges raised by the large-scale deployment of wireless sensor networks. The main modules within such a gateway for wireless sensor networks, for example digital radio modems and analog radio interface modules take the form of various separate physical blocks that may be joined together. This technique makes it possible to implement adaptable and scalable modular gateways that may be quickly and easily configured or suited to any situation, simply by replacing existing physical blocks or adding new physical blocks.
Claims15
A digital radio modem (200) for the modulation and demodulation of a digital signal, in accordance with a preselected radio access technology, wherein said digital radio modem is characterized in that it comprises a protective frame (201) of overall parallelepipedic design and a plurality of communication interfaces which are arranged within said protective frame (201),
- wherein the plurality of communication interfaces comprises:
- at least two first communication interfaces with a complementary device,
- wherein one of the first communication interfaces comprises:
- on one of the surfaces of the protective frame (201), described as the “upper surface” (202), two male SPI connectors (203, 203′);
- wherein another of the first communication interfaces comprises:
- on the opposing surface of the protective frame (201) to said upper surface (202), described as the “lower surface” (204), two female SPI connectors (205, 205′), which are designed to cooperate with the two male SPI connectors (203, 203′) of another digital radio modem such that, when a plurality of digital radio modems are connected:
- the male (203, 203′) and female (205, 205′) SPI connectors constitute the respective terminations of at least one SPI data bus, arranged internally to the protective frame (201), and employed by the digital radio modem for the transmission and reception of data to and from the digital radio modem(s) to which it is connected;
- at least one second communication interface with an analog radio interface module, wherein the second communication interface comprises:
- on one of the lateral surfaces of the protective frame (201), described as the “rear surface” (206), at least one other SPI connector (207) and at least one coaxial connector (208), which are designed to cooperate with the complementary connectors present on an analog radio interface module.
