A method of providing a software patch to an electronic device. A device containing a software patch for an electronic device may be plugged to an electrical outlet. A plurality of electronic devices may be queried, over a power line through the electrical outlet, for identifying the electronic device requiring the software patch. As a result, the electronic device requiring the software patch may also identify the version of the firmware installed on the electronic device. Test signals may be sent over the power line to determine the signal quality of various multiple carriers for using OFDM scheme. Suitability of various sub-carriers for sending the software patch over the power line may be determined. Higher density modulation may be used for higher quality sub-carriers to send the software patch to the electronic device. An acknowledgment signal for receipt of the properly received authenticated software patch may be received.

The invention provides an information interactive system and interactive method for a charging pile and a power distribution network. The information interaction is implemented by the steps as follows: S1, the load on the outlet side of the power distribution network is divided into a charging pile load and a non-charging-pile load; S2, the output electric quantity of the power distribution network is measured by a gateway meter; S3, a BPLC (broadband power line communication) communication unit of the charging pile and the BPLC unit of the gateway meter are in real-time interaction to collect the output port electric quantity of the power distribution network; the collected data is compared with the affordable maximum load of the power distribution network in real time; and S4, a charging pile main control sends messages to an electric vehicle BMS (battery management system)according to the real-time load; and electric vehicle BMS controls the electric vehicle to decrease / increase electric power or stop the charging process. The interconnection and coordination between the charging pile and the power distribution network can be realized through the gateway meter and the control unit; therefore, the reliable and economic operation of the power distribution network is ensured; and the power distribution network can guarantee the household electricity consumption of users preferentially.

A broadband powerline communication system makes use of knowledge of the spectrum characteristics of a local radio environment in order to improve system performance. A determination is made of the spectrum characteristics of a radio environment in the vicinity of the broadband powerline communication system that is transmitting data on modulated carrier frequencies. In order to avoid interference, certain ones of the carrier frequencies otherwise used by the broadband powerline communication system may be selectively masked based on the determination. The spectrum characteristics may be determined 1) in advance and used to compile a configuration database comprising frequency masking parameters; 2) by monitoring the local radio environment using the transmitter / receiver nodes of the system; or 3) based upon receipt of an indication from a conflicting user that the user is experiencing interference. Various combinations of these spectrum characteristic determination techniques may also be used.

A determination is made of the spectrum characteristics of a radio environment in the vicinity of the broadband powerline communication system that is transmitting data on modulated carrier frequencies. Certain ones of the carrier frequencies otherwise used by the broadband powerline communication system may be masked (i.e., not used) by all or part of the broadband powerline system in order to avoid interference based on the determination. The spectrum characteristics may be determined 1) in advance and used to compile a configuration database comprising frequency masking parameters; 2) by monitoring the local radio environment using the transmitter / receiver nodes of the system; or 3) based upon receipt of an indication from a conflicting user that the user is experiencing interference.
