20130100867 | MULTIPLE PROTOCOL RECEIVER - The presently disclosed subject matter is directed to methods and apparatus for providing a multi-protocol receiver for use in a radio frequency (RF) network. The receiver is designed to listen for multiple different packet preambles in parallel and, upon detection of a particular preamble, shift to demodulating the data portion of the packet using the single modulation technique associated with the particular preamble. Transmission of packets may be performed using a single radio frequency for all network devices or by frequency hopping techniques but using the same hopping pattern for all network devices. The receiver may be used with general communications networks or more specific applications, such as Smart Grid and AMI networks, and meshed networks of metrology devices. | 04-25-2013 |
20130100987 | Multiple Protocol Receiver - Implementation and operation of a multiple protocol receiver are described herein. In one example, a multiple protocol receiver in a node may alternate between first and second states. In a first state, the multiple protocol receiver listens simultaneously for a plurality of differently modulated signals. Such listening may be performed in a parallel manner, wherein a plurality of preamble detection processes each listens for a specific preamble. The listening may result in detection of a preamble of a packet, which triggers transition to the second state. The detected preamble may indicate a protocol used in transmission of the packet. The received packet may then be demodulated according to, for example, a data rate, synchronization, redundancy and/or other factors indicated by the protocol. The received packet may be utilized by the node or retransmitted. The multiple protocol receiver may return to the first state to repeat and continue the procedure. | 04-25-2013 |

20130208627 | FIRMWARE DOWNLOAD WITH ADAPTIVE LOST PACKET RECOVERY - Disclosed are methodologies for implementing a firmware download to endpoints in a mesh network. A firmware package is divided into a number of blocks, each block containing a number of packets and sent as a broadcast to endpoints in a wireless mesh network. A number of redundancy packets are sent to permit calculation of lost packets. A maximum number of redundancy packets to be sent is determined and a forward error correction code is developed depending on the maximum number of redundancy packets and the total number of firmware packets to be sent. A first block of redundancy packets, less than the maximum number, is sent followed by additional blocks of redundancy packets depending on reports from the receiving endpoints. | 08-15-2013 |
