7. UPS Maintains Network Connection even during Power Failure
Yutaka Electric Mfg. Co., Ltd. exhibited the UPS (Uninterruptible Power Supply) with built-in PLC adaptor. Network connection can be maintained at the event of sudden power troubles since the built-in battery can supply power to HD-PLC module in case of a power failure. With this system, it has the potential for applying it to cases such as being able to keep verification devices placed in confidential areas running in case of power failure.
8. Network Connection Using USB Terminals
Many HD-PLC adaptors that can connect to USB terminals were showcased at CEATEC. Expanded application in various areas is expected since even digital electronics without Ethernet ports, such as game consoles, can be connected to the Internet by only using USB terminals.
9. Stable Connection despite Wiring Phase Differences
In response to growing HD-PLC use, other businesses have started to pay attention to the technology. I-O Data Device. Inc. presented an instrument can easily check wiring phases in the household (see Note 2) that effects the communication speed of HD-PLC, and also exhibited a signal bridge that can mutually connect even if wiring phases differ. The company is working on solutions to remove any hurdles in using HD-PLC.
Note 2) Wiring phase: Connection types of AC power wires within a home. In-house power lines use 2 voltage wires to gain 200V of power, one of which a 100V plug uses. Communication speed depends on which power line the adaptor uses.
10. HD-PLC Applicable with Coaxial Cable
Sun Corp. exhibited a modem for TLC (TV Line Communication) which allows network connections via coaxial cable for TV, demonstrating connection examples. This modem was derived from HD-PLC technology. It is expected to be used at hotels and at public facilities where coaxial cables are already present.
11. New Modules Now Suitable for Built-In Application
Murata Manufacturing Co., Ltd. exhibited its HD-PLC module, the PLCP0100. It uses IC chips supplied from Semiconductor Company, Panasonic Corp. Unlike existing modules, it is equipped with an interface called MII (Media Independent Interface), with better usability than the Ethernet, so that it can be flexibly used for embedded applications.
12. Panasonic Communications Exhibits HD-PLC Modules Development Roadmap
MMDPMS250 series (photo: second from right) realized a huge decrease in size, integrating analog parts such as noise control filters, simplifying high-speed power line communication. The MMDPMS235 series (photo: lower right) is the latest module which achieved serial communication via power line by using HD-PLC development kit, making it possible for users to control home electronics. Applying this to systems such as power monitors, energy saving effects can be expected in the future.
13. Booths set up to experience HD-PLC hands-on
A booth was at the exhibit to freely touch and try HD-PLC network. Many visitors gathered to experience the high-speed performance of HD-PLC. There were numerous other application examples at CEATEC this year, indicating the growth of HD-PLC.
