How Telecommunications Works=-+ beyond wires

Schedule

How do people in Nippon use smartphones to cheat their way into the subway?

They use NFC. A short-range, standards-based wireless connectivity technology, based on RFID technology that uses magnetic field induction to enable communication between electronic devices in close proximity. Easynow.

the obvious Telephone = the power to the wires

fluctuates to match the sounds carried.

And now for AM radio

Radio = a transmitter converts the sound waves to an analog or digital signal by modulation of frequency (FM), phase-shift (Bluetooth), or amplitude (AM). The electrons on the surface of the receiver move when the sound waves strike them, then the receiver processes them back into their original sound.

the kind of obvious

old TV, obvious in a Willy Wonka way

old TV = a transmitter converts the recording to UHF (500 to 1000 Megahertz) or VHF (60 to 130 Megahertz) modulation which a receiver reverts.

Oblivious, really... cell phones (advanced, but not honors)How do they work? Magic. No, from Wikipedia, “The first handheld mobile phone was demonstrated by Dr. Martin Cooper of Motorola in 1973, using a handset weighing 2 kg (4.4 lb).

( The first mobile telephone call made from a car occurred in St. Louis, Missouri, USA on June 17, 1946, using the Bell System's Mobile Telephone Service, but the system was impractical from what is considered a portable handset today. The equipment weighed 80 lbs, and the AT&T service, basically a massive party line, cost $30 USD per month (equal to $337.33 today) plus 30 to 40 cents per local call, equal to $3.37 to $4.5 today. ) “

cell phoneswork by connecting to a cellular network owned

by a mobile network operator. A key feature of the cellular network is that it enables seamless telephone calls even when the user is moving around wide areas via a process known as handoff or handover. Features of the advanced phones –

SMS “text” messages

SMS text messaging is the most widely used data application in the world, with 2.4 billion active users, or 74% of all mobile phone subscribers.

It was originated from radio telegraphy in radio memo pagers using standardized phone protocols as a means of sending messages to and from mobile handsets.

WAPWAP (or mobile web payments) consumer uses web pages displayed or additional applications downloaded and installed on the mobile phone to make a payment. It uses WAP (Wireless Application Protocol) as underlying technology, which leads to follow-on sales at that webpage.

Near Field Communications (NFC) Near Field Communications (NFC) – pay close attention, this is the future, a short-range, standards-based wireless connectivity technology, based on RFID technology that uses magnetic field induction to enable communication between electronic devices in close proximity. (from Wikipedia, Mobile payment) Used mostly in paying for purchases made in physical stores or transportation services. A consumer using a special mobile phone equipped with a smartcard waves his/her phone near a reader module. Most transactions do not require authentication, but some require authentication using PIN, before transaction is completed. The payment could be deducted from pre-paid account or charged to mobile or bank account directly.

The cloud The cloud Smart Phones Smart PhonesWhen the phones entered the next generation of technology, 2G, the

first smartphone was introduced, the Nokia 9000 Communicator (1996). It added PDA functionality to the basic mobile phone at the time. This brought the phones beyond calls, cameras and kind letters.

Most have “SIM” cards or an R-UIM, which give the phones internationally unique serial number identifiers.

Features now stretch beyond SMS text, and third generation now has standard software applications using High-Speed Download Packet Access that makes possible fast GPS navigation, music (MP3) and video (MP4) playback, RDS radio receiver, alarms, memo recording, personal digital assistant functions, ability to watch streaming video, video download, video calling, built-in cameras (1.0+ Mpixel) and camcorders (video recording), with auto focus and flash, ring tones, games, PTT, memory card reader (SD), USB (2.0), dual line support, infrared, Bluetooth (2.0) and WiFi connectivity, instant messaging, Internet e-mail and browsing and serving as a wireless modem. Nokia and the University of Cambridge demonstrated a bendable cell phone called the Morph .

Digital TelevisionDigital Television

Digital Television (HD and IPTV), the CPU meets world, on your TV! HD is a format (one of many compression algorithms used worldwide). The US has finally adopted one for HD TV, and incidentally, adopted one for HD DVD, BluRay.

IPTV

I don’t know how this works, and I work for AT&T! Actually, AT&T sends a video stream to the residential gateway (router) which then sends your internet protocol Television video stream to your TV (‘s set top box and then to your TV).

The future

Peer-to-peer – parts of the data package are stored on individual’s computers across the web and an application grabs from each computer and sends it to you.

The future

Actually – tomorrow starts today. The FCC is determining its stance, which will hopefully in the US continue on the same track of how the telecommunications act update in the 1990s balanced previous large-scale capital investments with potential future equity to start-ups, all with the idea to develop a national “wire-up”.

The future

In an all together different (oxymoron) presentation, I will present my ideas of how we could:

House data at central locations and simply rent keys to unlock and stream bi-directionally, wired or not, to whatever local device.

Money and maintenance could be automated.
