Abstract
A method of transmitting data from a transmitter to a receiver in an unsynchronized, ad-hoc, low-power, wireless network including: creating a packet including a header and data; and retransmitting the same created packet a plurality of times in succession.
Claims16
A method comprising:
- creating a packet comprising a header and data;
- and
- transmitting, from a transmitter to a receiver in an unsynchronised, ad-hoc, low-power, wireless network, without a schedule, the same created packet a plurality of times in succession one after the other as a concatenated sequence in the same communication channel, wherein the same created packet is an information packet comprising a time field and not comprising a data payload.
An electronic communications device comprising:
- a transmitter configured to transmit data to a receiver using an unsynchronized, ad hoc, low power, wireless network;
- and
- processing circuitry configured to create a packet comprising a header and data;
- wherein the transmitter is configured to transmit, without a schedule, the same created packet a plurality of times in succession one after the other as a concatenated sequence in the same communication channel, and wherein
- the same created packet is an information packet comprising a time field and not comprising a data payload.

A method comprising:
- switching on a receiver according to a first schedule;
- detecting reception of one of a succession of same packets transmitted, from a transmitter to a receiver in an unsynchronised, ad-hoc, low-power, wireless network, without a schedule one after the other as a concatenated sequence in the same communication channel;
- wherein the same packet is an information packet comprising a time field and not comprising a data payload;
- extracting data from the received packet;
- and
- switching off the receiver until it is next scheduled to be switched on.

An electronic communications device, the device comprising:
- a receiver configured to detect reception of one of a succession of same packets transmitted, from a transmitter in an unsynchronised, ad-hoc, low-power, wireless network, without a schedule one after the other as a concatenated sequence in the same communication channel, wherein the same packet is an information packet comprising a time field and not comprising a data payload;
- and
- processing circuitry configured to switch on the receiver according to a first schedule, to extract the time field from a received information packet and to switch off the receiver until a time, dependent upon the extracted time field, for receiving a data packet comprising a data payload.
A method comprising:
- at an unscheduled time, transmitting, from a transmitter to a receiver in an unsynchronised, ad-hoc, low-power, wireless network, a plurality of times in succession, one after the other as a concatenated sequence in the same communications channel, an information packet for determining a wake-up time at a receiver;
- wherein the same packet is an information packet comprising a time field and not comprising a data payload;
- and
- transmitting, from the transmitter to the receiver in the unsynchronised, ad-hoc, low-power, wireless network, a data packet comprising a data payload at the wake-up time.
