Radiocalc or dBcalc - Conversions RF Engineering

Besides classical functions and dB conversions, RadioCalc includes a converter of Power to field strength commonly used for EMC/EMS test-set-up. Also impedance can be represented as a function of reflection coefficient (somehow like an electronic Smith-chart). This and many other functions are obtained by clicking into the arrow of the "Conversion off" window.

Radiocalc - Convertisseur Radio Universel

Radiocalc - Convertisseur Radio Universel

Thanks to RadioCalc the different dB charts are obsolete by computing the ratios of Power (W) or Voltages (V) according to dB = 10*log(P2/P1) ou dB = 20*log(V2/V1).

Just for a trial : type 100/10 (or just 10) and push the dB button as the 'W' mode is chosen, the result will be 10 dB, then choose the 'V' mode by clicking in the V button (in the Quick dB window) push again dB, the result is now 20 dB.

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.

Wired Wi-Fi or WiGig for enhancing Range

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.

DTH for Software Downloads and Updates

Here is an example how i feel a DTH portal can interleave with interactive optical/wireless networks on land.

Let us assume Simtel has a DTH Channel. They broadcast MS updates from 10.00 AM to 10.30 AM. Linux updates at 11.00AM and Mac at 9.00 AM. All updates, some repetitive in gzip format and a advance xml feed indicating and enabling parsing of content on a digital device.

DTH for Software Downloads and Updates

From 1.00 PM to 5.00 PM is subscriber time. "Your favorite software is 'played' at these times". A user can use his phone or tablet to request a media. paid or free. All software will be broadcast at the time slot. With a xml feed/sitemap.

The user transfers the software from dth box to his computer using usb/lan. If he has been mailed dual layer decrypt keys he will be able to unzip the paid software. Else he can look thru the formatted/presented xml for any free software/media he would like to use.

DTH software providers can monetize using software developers to publicize their demo versions. Other firms from computers to toothbrush providers can give a "Media Promotion Pack" with wallpapers/freeware/video/audio/presentations and discounted/free offers.

Auxiliary Software Media DTH Download Box - Reduce Net Congestion

# Either you connect the USB of this Download-Box to Router to make a media server for your Netbooks & Tablets or plug it to your Desktop PC.

# This has a Tiny LCD Touch Screen, Key in the URL & Press Get, Wait. Media ready beep will come in a few secs. Satellite Delays don't matter.

# Invent something like Satellite Software/Media Download DTH Service - Small dish on Roof, A Stand alone Box with One Tera Byte HDD and USB.

DTT an interweave of WiMax and DTH

DTT - Direct To Tablet is a Technology, That is required in the communication Infrastructure, both for wireless and wireline networking. At Least till Optic Fibers Reach Every home.

If the Satellite Broadcasting Technology and RF Wireless Semiconductor Technology, advances fast. It may be Possible for DTT as a small module in the Tablet. This is TV on Tablet with Interactivity, as we have TCP/IP as well on Wi-Fi. This method does not load the TCP/IP infrastructure with HD Videos or Audio.

The other way is Intermesh WiMax with DTH to make Interactive TV on Tablet. The HD Media is requested by a Net Protocol, then it is got form Sattelite on Local DTH and comes to Tablet over WiMax. This way a HD Video need not travel a long distance, around the globe, causing traffic jams.

DTT an interweave of WiMax and DTH

I am sure, still nobody got me, or what i am talking of, but its is pleasant that way. Here is an image i had done a couple of years back. Try incremental levitation of the thought process, then you shall perceive a Tux on the Clouds.

Directly or Indirectly it is Tux who has made tablets possible in most all of the tablets you see today. They have made it happen. - In fact all are, some admit, some do not.

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

Facts of EMI and RFI from the Inside

Electromagnetic interference (or EMI, also called radio-frequency interference or RFI when in radio frequency) is disturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source.
 
Electromagnetic interference Wiki

Vertical polarized VHF- UHF biconical antenna

Vertical polarized VHF- UHF biconical antenna
170 – 1100 MHz with omni directional H-plane pattern

Who would know better about Radio Frequency Interference and ElectroMagnetic Interference more than the Hams or Amateur Radio Community.

If they have to communicate effectively using limited resources, they have to deal with EMI/RFI effectively, While they build their equipment or combat Noise from other Machines and Installations nearby.

EMI RFI Mains Filters

This problem needs more practical involvement and experimentation to learn, compared to learning something like Digital Electronics.

Equipment and Electricals like SMPS, AC/DC Drives, Motors, Solenoids and CFL Lamps are to be built/reinforced for low EMI/RFI emission/radiation.

Sensitive Medical Equipment like ECG or even a Aircraft can be seriously affected by Noise.

In microwave circuit design S-parameters are very useful for the full characterisation of any 2 port network. In contrast to z,y and h-parameters, which require broadband short circuited and open circuited connections at the TEST ITEM for the measurement,

S-parameters are determined with input and output terminated with the resistive characteristic impedance of test systems (generally 50 ohms in a coaxial line system). Parasitic oscillations in active devices are minimised when these devices are terminated in resistive loads."
