Reliable, robust, low-cost technology for power line based home automation and device control is available today in ITRAN Communications' DCSK based IT800 modem. The integration of the IT800 with Microsoft Simple Control Protocol enables the development of a wide variety of in-home PLC based applications with significantly superior performance than existing PLC command and control solutions.
Fortunately, a repeater provides a practical solution for both of these problems in any X-10 compatible installation. In the X-10 standard command protocol, a controller sends the signal twice, back-to-back. The repeater listens to the first signal, then transmits on top of the second signal. It can boost a weak 25 mV signal to a 5V level that receivers can easily hear. The repeater also concurrently transmits on to the other pole in a home wiring system.
The Archronix ArcWay ZigBee to WSDL gateway allows two sets of standardized yet disparate technologies to communicate with each other. You can buy products from a variety of vendors and they will be able to plug and play together.
Clearly 2001 has been a mixed bag in the areas discussed above with the number of bright spots being equaled by instances of postponed growth. The depth of this technology industry downturn has been unprecedented by most metrics. It has reinforced the belief that the tech industry despite its allure is cyclical beyond just the semiconductor segment. Nevertheless over the long-term the technology industry, as an aggregate, should post healthy positive growth.
The newer, and at this point more expensive, 802.11a standard is able to transmit data at speeds up to 54 Mbps, which is more than adequate for today's video and audio technologies. In fact, according to a recent report from the Gartner Group, Inc., it has "enough capacity to simultaneously support two streams of standard television content, data traffic among multiple PCs in the home and an HDTV stream".
I was most impressed with the quick and easy setup and the fact that I didn't need to train the voice recognition system at all. This is a fun ... fun ... fun product that can pretty much become your sidekick in operating your home automation system, answering, dialing and taking messages as well as getting your favorite sports scores, stock prices and weather reports from the internet. What else do you need? And the very best part ... just say "Goodbye" or "Thank-you" and HAL goes to sleep until you awaken it with your next desire.
The digital home continues to evolve and smarter appliances continuing to perpetrate the home. These smarter appliances and the need for sharing broadband data, voice, and video is pushing the need for home networking. While several technologies exist the technology that provides high-speed and reliable delivery of voice, data and video will win. IEEE 1394 is one such home networking technology that provides both high-speed and reliable delivery. The proliferation of 1394 as the A/V standard will be accelerated through the use of HAVi as its middleware solution to connect disparate devices, thus providing a complete solution to the consumer.
In an office setting, printers are not replicated in everyone's office. A printer's capabilities are distributed by networking it; thus multiple users can share one device. Home entertainment networking is analogous to the office printer scenario, permitting multiple users to share the capabilities of entertainment devices and providing benefits to both the consumers and service providers.
At COMDEX 2001 HomePNA announced the Voice-over-HomePNA (VoHPNA) protocol, which extends its 2.0 specification to include support for digital voice services. This announcement makes HomePNA the first home networking protocol to deliver a network-based framework for delivering toll-quality digital telephony services for consumer price points.
What Whitecap2 does is give priority to the game, movie, and other multimedia content you're running, allowing it more usable throughput within the 11mbps pipeline. If you imagine 802.11b as a highway, picture it with no traffic signs, no lanes, no lights - just data whizzing around with no traffic cop to maintain order. What Whitecap adds, to extend the metaphor, is a commuter lane for multimedia content.
Some of the products discussed provide adequate performance under ideal conditions, but there are many things that emit radio interference that can impact performance. These include stadium lights, cordless phones, microwave ovens, wireless LANs, and anything else that operates in the unlicensed 900 MHz or 2.4 GHz frequency band.
The all in one unit contains a high resolution CCD camera and an embedded web server. There are inputs for 3 analogue camera's (CCTV). Other features include an interface for adding on a pan/tilt/zoom function as well as adding a motion sensor. All this can be controlled with a standard web browser ... no additional software needed.
When you consider the versatility and diverse capabilities of powerline home networking solutions, it is clear that there is strength in numbers. Bringing together 90 companies from a range of industry sectors ensures that consumers who want to create a home network will be provided with a variety of cost-effective, HomePlug-certified products that will all work together.
With just a Web browser you can control lights, appliances, a security system -- almost anything with a power switch. In my home, the system controls the pool pumps and cleaner, opens and closes drapes, and even tells me when someone is coming up the driveway or if I left the garage door up.
I'm not going to redo the in depth review of HomeVision here. My original review is still relevant so click here if you want to get into the nitty gritty of this controller. Suffice it to say that when I got my new HomeVision it only took a few minutes to change over all of my schedules and devices from the Enerlogic system that I have used for the past 10 years. I did not lose one day of control and in fact added scenes and modes that I had been thinking about for some time. Not having to write and debug control code has made this experience a pleasure.
