Abstract
Low-Power Wide-Area Networks (LPWANs) are actively developed, which is supposed to provide wireless communication in the “smart” city concept. In LPWANs, tens of thousands autonomous wireless endpoint devices can transmit data to a common central node. To achieve this, ultra-narrowband (UNB) technique can be efficiently used. According to the UNB principles, each device randomly selects a narrowband channel (typically, 100 Hz) from total system bandwidth during the transmission. However, there is a problem of the increasing probability of packet collisions, which, in its turn, leads to the loss of information. This paper simulates the data transmission from many devices in a UNB system based on the “OpenUNB” specification that provides for multiple transmissions of the same packet at a given time interval to reduce the probability of packet loss. Using simulations, we have estimated the probability of packet collisions for 10,000 devices transmitting data the given number of times during the day.
