Wired Wi-Fi or WiGig for enhancing Range

You have a big office of 3 Floors or a Home which is not Wi-Fi Friendly and it does not have the provision for LAN or any other wiring. Even a distant room/garage or basement beyond the Wi-Fi range.

Wireless Gigabit Alliance – WiGig 60 GHz

If we could build a Wired interface for Wi-Fi and WiGig then such rooms can be brought within range. A wired interface without wires, then you think of optics, not even optic fiber …. that will build up the cost for home networks.

Wave Guide may be an answer, a wire that pretends to be a waveguide. Let us take a thin flexible plastic tube, 2-3 mm in dia, 1mm wall thickness of tube. The outer wall of the 3mm tube is coated with a suitable copper alloy. Above that a thick insulation to protect from mechanical damage. This may act as a waveguide if properly designed, probably the way or pattern in which the metal is coated.

Fixed WiMAX SoC and RF Module – Fujitsu

If this works in theory, then Pump RF on one end with a little more juice, just like in Optic fibers. The other end may get enough signal strength for good speed connectivity. It will at least be still wi-fi on waveguide and easier to implement than RJ45, these LAN cables, connectors and switches include many components and modules, that make it very fussy and unreliable.

Wi-Fi seems to be very friendly and safety has also improved now. So a wired, one wire or waveguide to extend Wi-Fi can phase out the RJ45. I like RJ45 similar to the sentiments i have for the Printer Port and RS232. Then USB has just taken over. Change is inevitable, Find a way out of RJ45 for good.

Wireless Handheld Multimedia Computers

The Average home user or a majority of mankind have trouble even when operating a TV remote control. Things are not as simple as a Water Tap or a Toggle Switch. An Easy to use Handheld is more important than any technology or features that may be available for that. Ergonomics, Utility or Application, Quality and Cost are the basic requirements of the consumer.

Wireless Handheld Multimedia Computers

A Handheld gadget for the masses, needs to be a Entertainer and Communicator. It has to be wireless and should at least get into a Coat Inner pocket or Small Bag. It is a Duarble Consumer Electronics Product, comparable to the first Popular Tape Recorders from Philips or Grundig.

Wireless Gigabit Alliance – WiGig 60 GHz

Wifi and WiMax are the things that are being talked-blogged about and being tried. I just got some idea about these technologies and have my feedback or understanding.

If Somebody asked me to set up a low cost wifi connectivity in a small housing complex, I would just strap a wireless router on the pole on every street corner, the poles or junctions being the ones used for existing cable broadband. Then depending on subscriptions and demand, improve the capacity of the network within the budget of the colony.

The handheld can have simultaneous connection to two or three routers and as the person moves, drop a weak path and take up a new router which is strong. This is just my hunch.

The Handheld could be used for three types of wireless connections.

Full Multimedia Duplex – Like Video Telephone, WebApps – 100 units money charge per hour.

Semi Multimedia Duplex – Like Interactive Quiz, Games – Up is Text, Down is Video – 50 Units /hr.


Multimedia Broadcast – Digital Radio Podcast, TV Show Podcast, Movie Podcast – 15 Units/hr.

The TV and Radio Shows on subscribed podcasts can be downloaded and stored when it is transmitted live; but seen any time, any number of times, but transmitted only once. This is a wireless Transmission with an advance program xml feed info. It is just like Regular TV. This is to avoid bandwidth wastage on multiple downloads of same show by the people in one block. Even software updates and games can be brodcast and stored in background.

The usage of Internet and phone remains duplex and will take more resources. The handheld usage for entertainment may be very high. Duplex for that will cause excess costly load. Normal usage of Internet for browsing, mail and webapps may become difficult as more entertainment load builds. Entertainment on Handheld is best as a one time brodcast with a advance feed.

Drawing Tools for Electronic Schematics in Android

Conclusion – Wireless Handhelds connectivity must have separate interfaces for Web and Media. The Web is the same as Lan Wifi but Movies and Games can be connected by a Broadcast Show. And seen on Handheld by wireless Programmable Live Reception with storage.

Wireless Home Automation and Application Server

The PC has much Evolved, From XT to AT, then from 286 to 586, the evolutionary trend continues. The Speed: GHz, Space: GB and Software: Linux-XP, have grown rapidly. The other vital things Interface, Networking and Power Consumption moved a bit slower. So some suggestions on the New Desktop for Small Office and Home Standard, that is crucial in the present computing scenario.

Enterprise Level Hardware and Software can be extrapolated from this idea for a SOHO. An Enterprise is like a SOHO Cluster. One big Homogeneous Entity is unstable and unreliable. When small varied, self-dependent entities collaborate to form an Enterprise, it is a Cluster of SOHOs, which is a Reliable and Resilient Entity.

Wireless Home Automation and Application Server

A Green solution could be New Desktop Computing Standard – The quiescent losses in this is only the wifi server cube, which can serve 6 tablets or UMPC. So if 6-12 people are using computers, many desktops need not be on. Tablets, Laptops and Notebooks consume less power and run on batteries. Thin Custom Notebook and Tablet Clients can use one OpenOffice on the WiFi Application Server cube

Power Electronics Design Methods

I first saw this practically in the Orthodox Cherokee SMPS. This is where we differentiate from Engineered Products and just Mass Production without following standards. The Cherokee SMPS was a work of art, perfect in all respects.

The Copper Desert or Isolation Land

There is a No Man’s Land in PCB. Any good power electronics designer should/will know. Product Safety and HV Isolation, Quality and Reliability all depend on this.

High Energy Circuits

Power Electronics Design Methods

These things don’t come overnight, it is a culture, learning, experience and integrity of some of these American Firms. Reliability and Product safety are important. Every human values his life very much. A manufacturer too should appreciate this.

Coming back to isolation, Keep in mind creepage distance, High energy circuits and Low voltage circuits should have clear isolation, use the best insulation. Fire and shock hazard. Mains HV transitions, spikes.

Regulated High Voltage Power Supply

Power supply faces all these, even other areas where a Human Life or Property can be endangered.

HV High Voltage Reliability and Safety

Use a Servo Stabilizer or CVT Constant Voltage Transformer or at least an Isolation Transformer. The First Defense form HV Surges, Spikes.

High Voltage Polyester & Polypropylene Metallized Capacitors in Stepdown Supplies should be Fire Retardant & Self Healing with a MOV too.

Tech Ideas as Feedback – Computers

These are some ideas, comments, feedback and communication that i have had over the past many years online. 2006-11

Photonic Speeds

The real speed can be seen when we switch completely to photons and photonic circuits. No more electrons. Blazing Tera Hertz Transfer Speeds. Just a few decades away. Another smart alec comment i made at the site of a major speed provider.

System-on-Chip – SoC – IP

3D Hologram Newspaper

3D Hologram Newspaper

An Interactive 3D Hologram Newspaper that is Projected by a Small Rechargeable Pendent or Desktop Device. It can be a MultiMedia 3D Book, Magazine or Newspaper. It can be used even when lying down on a bed. It can be used on a Restaurant, the group can read the day’s Paper. (An idea i gave at a website with a Questionnaire, years ago)

Digital Signal Processing – DSP

Rechargable Wireless Peripherals

Buy only those Wireless Peripherals or Even Keyboard / Mouse, that can be recharged & dockable or on a Ferrite / Magnetic, No wire/metal charging base. (Just drumming up an old idea of mine)

Storage Tripod Hybrid for Reliability Speed

The wear and tear, fragmentation on HDD can be reduced using a Tripod Hybrid. Access Speed improves too…

Top Layer is RAM Drive with Li-ion Battery. Second layer is Flash. Third is the Spinner HDD.

All active files of user are on RAM drive and backed up on Flash by intelligent Drive (not CPU). The files go into HDD after they have been stable for over an hour. As HDD sizes are increasing. The files and file system can be like svn and maintain 3 versions of all dynamic files. This is useful for user also and HDD too.

Storage Tripod Hybrid for Reliability Speed

Static files like Binaries can be on one area of HDD. Frequently accessed binaries are promoted to flash layer. Extremely frequent to Ram Layer. The HDD now is less stressed and lasts longer and is a stable backup. Power failures immune.

Bare Essentials

A supercap built into a HDD. On Brownout OR Power Fail. The falling ramp is detected beyond an isolating diode. It says to HDD uC … Look there is something funny with power now. The HDD uC at once finishes the work at hand, drawing its juice from the stable supercap, parks its heads and goes to sleep.

When power is stable again, it wakes up and the supercap is replenished too. This way damage to HDD is avoided, these happen when .. battery connection problems in laptop or mains power fluctuations or switching power systems carelessly. It makes HDD idiot proof at least electrically.

The SmartRadio – eNewspaper Delivery

A Jpeg browser device like Digital Photo Album. It has a LCD Screen and a FM Radio interface. It costs less that $100 or comes free with 5 yrs subscription to a paper. – The SmartRadio

In the early morning it downloads the media on a built-in locked FM receive only radio.The FM newspaper station just transmits a few minutes of encrypted digital data. This is stored and static jpeg pages generated, which can be easily viewed and read using scroll and zoom using a convenient handheld device.

XML-HTML FM Radio – FM Radio enhancements

FM radios consume less power and are affordable, now we should add a small LCD display like you have in cellphones. Xml should be frequency modulated and transmitted by fm stations in adjoining bands.

Electronic Engineering Magazines

Xml is demodulated by fm radio and displayed in the lcd display on radio. This way news can be transmitted to many people without internet or tcp/ip. This is just one way broadcast of xml or html information, it need very less freq. Even html, jpeg, png and flash can be broadcast by fm radio. Product advertisements can also be sent in this format. Just tune into your xml fm radio station with your color lcd portable radio and presto news, ads, pictures, semi static but can reach millions. The radio tuner can tab over different stations.

Cost Effective eNewspaper Delivery Jpeg Radio

If it works and people start using it, it could be a standardized paper reader which can manage multiple subscriptions. The subscription can be bought in the form of a chip card or monthly billing. Then it can move to color and slowly to WiMax with Rich Media and Accessibility like Read aloud Text, Translate and Search. This depends on how far the media can go in modernizing and how safe the system is. Too bad that looks like a Tablet Computer again.

Everything is converging to Wireless Internet and Cloud Computing. The Tech Prophets had foreseen this phenomena prematurely.Then there was a oracle from the sky …..

There is enough bandwidth on the sides to accommodate a Low Resolution Jpeg or GIF Animation. Seeing this on a Color LCD Radio will make it Smart.

Now we have SMS Song Requests. The names of the Enthusiasts can come on the LCD screen by xml. Some Text can be easily pumped on FM Frequencies as a thin xml file. Even the details of the Radio Show.

SmartRadio may be One way communication. But we can add static pictures and text !

We could also make a Hybrid Device that combines the Mobile Data or Wi-Fi.

“Each Man will have a HandHeld Tablet Computer that will pack the power of a Super Computer”
