Abstract: IOT device-based messaging communications systems and methods are disclosed herein. An example system includes an Internet-of-things backend system comprising IOT devices that implement proximity and physical web discovery services and implement a modified short-range wireless communication protocol stack for communicating with communication devices at a kernel level; and each of the communication devices being configured to with receive messages from the Internet-of-things backend system over a short-range wireless connection, the messages are presented to the communication devices without an application being installed on the communication devices, the modified short-range wireless communication protocol stack being configured based on a short-range wireless protocol that is active on the each of the communication devices.

Abstract: Messaging communications systems and methods are disclosed herein. An example system includes a beacon architecture including a server; and a plurality of beacons arranged around an environment, the server being configured to sense a real-time center of gravity of a communication device from any of the plurality of beacons receiving communications from the communication device, the real-time center of gravity being a location of the communication device within the environment, transmit a notification to the communication device, the notification including a link to content based on the real-time center of gravity, and transmit the content to the communication device based on a selection of the link.

Abstract: A two-way packet radio-based electronic toll collection system is to be installed on a highway and includes a main communication tower for transmitting continuously downlink communication packets that contain information regarding available uplink communication channels, and an in-vehicle unit installed in each vehicle passing along the highway to receive the downlink communication packets. The in-vehicle unit is capable of selecting one of the available uplink communication channels. The in-vehicle unit and the main communication tower exchange toll collecting and payment information wirelessly via the available uplink communication channel selected by the in-vehicle unit and a downlink communication channel corresponding thereto. When collision occurs along the packets transmitted by a number of in-vehicle units, a retransmission scheme is applied for each in-vehicle unit to guarantee successful communication between the tower and the in-vehicle unit.
