• Laws start to change in mandate ships use of radio


1914 – a snapshot

• 10% of all ships carry wireless – growing rapidly

• Wireless Telegraph stations covered the developed world

• Ships newspaper arrives daily by telegraph

• Transmission are “Damped sparks”

• Professional transmissions up to 200m (1.5MHz)

• Amateur transmissions above (“useless” spectrum)

• Titanic disaster allowed monopolisation by Marconi

– Nearby ships had closed down at 11pm – missing SOS

– Radios not universally fitted – cost, space, manpower

• Production of continuous waves subject of discussion

• “Broadcasting” sporadic

• Anuity rates at 65: Men 14%, Women 10%


The 1914 Transmitter

• Spark transmission the norm

– Power 40W – 5kW

– Efficiency low ~ 10%

– “Damped Wave”

– What was its spectrum?

• Spark = broad

• Single resonator, Q of 20

• Antenna Q of 20

• Spark resulted from transformed AC or DC supply

– 25Hz – 60 Hz = 50-100Hz

– Transformer deliberately leaky – air gap

– Interupter disc added 3-500Hz “note”

» Aided detection – human ear ~10Hz detection bandwidth

Rotary disc spark gap


Spark transmitter spectrum


The 1914 Receiver

• Use of Syntony – resonance

• Tuned antenna structure

• Main input tuned circuit

• Variable coupling to exchange senstivity and selectivity

• Detector

– Coherer

– Magnetic

– Crystal – many types

– Thermionic diode – novel


1909 receiver


1912 detector board


1912 Semiconductor technology

• Peroxide of Lead –

• Perikon - this is a detector that uses two different minerals,

usually zincite and chalcopyrite, in contact with each other for

detection.

• Iron Pyrite- a single mineral detector that, at the time, was

thought to be easy to use and fairly sensitive.

• Carborundum


The International Convention, London, July 1910

• Article 3 – bound to exchange..reciprocally..regardless of type

• Article 4 - NO JAMMING

• Article 10 – Allowable charges:Coast, ship, land, relays

• 1800m for long range

• 150m for radio location

– Art 7

• Minimum power necessary

• As little damping as possible

• NO sparks only to the aerial (except SOS)

• 20WPM min

• High selectiviy rx


1910 Convention - cont

– SII, Art 14

• Ship first

TV and long wave radio broadcasting

suspended during the war and

medium wave reconfigured to make it

harder to use as a homing beacon for

German bombing raids

Cicero 100 BC

‘The sinews of war… a limitless supply of money’

Victory goes to the side that makes fewest mistakes.

If it hadn't been for Wellington we would all be speaking French

If it hadn't been for Hitler we would all be speaking German

Hitler’s catastrophic faith in cryptography but biggest mistake

declaring war on Russia and America- the world’s two largest

economic powers

Churchill – ‘America can always be relied upon to do the right thing,

having exhausted all other alternatives’

Foundations of Mobile• 1947: D H Ring, Bell Labs, “Mobile Telephony – Wide Area

Coverage”

• BUT it was the car radio telephone service that evolved.

• UK: the GPO introduced a 50 channel system using

Stornophone equipment which was enhanced further in

1983 with automated connections. The Public Radio

Telephone System Four (PRT4) was the final iteration.

• Radio ‘zone’ concept first trialled in 1969 using payphones

on the Metroliner train service between New York and

Washington.

• 3rd April 1973 – Motorola develop the world’s first handheld

‘cell’ phone.

Foundations of Mobile

The Mobile Network• FCC approval was slow.

• In 1975 Bell Systems were permitted to begin a trial

• In 1977 the FCC approved AT&T to offer a service in

Chicago.

• Trials also conducted in Stockholm in 1977 (NMT) and

Japan in 1975 (NTT).

• Nordic Mobile Telephone System (NMT450) began

operating in Denmark, Sweden, Finland and Norway in

1981.

• 12th October 1983, first USA commercial cellular service

opened in Chicago using the Advanced Mobile Phone

service (AMPS).

UK ETACS Networks• 1982: UK Government announces two licences

• One to BT – creates BT Cellnet; one open to competiton

• Second licence awarded to Vodafone

• Development of AMPS – Total Access Communication

System (TACS).

• 890-905MHz and 935-950MHz. Giving 600 x 25kHz

analogue channels

• Later extended to 872-905MHz and 917-950MHz to give

1320 x 25kHz analogue channels. (ETACS)

Seeking a European standard• 1986 - 100,000 mobile phone subscribers within the UK

• 1987 – 200,000

• 1995 – 7% of the UK population

BUT everything stopped at the English Channel and costs

of ownership remained high.

7th September 1987 – EU Memorandum of Understanding

on the implementation of a Pan-European 900 MHz Digital

Cellular Mobile Telecommunications Service by 1991.

2100MHz band, this band was to support the new 3G technology

• The outcome of the auction was 5 awards:

– Licence A – TIW (H3G) at a cost of £4,384,700,000

– Licence B – Vodafone at a cost of £5,964,000,000

– Licence C – BT at a cost of £4,030,100,000

– Licence D – One2One at a cost of £4,003,600,000

– Licence E – Orange at a cost of £4,095,000,000

• A total of £22,477,400,000 was raised for the UK treasury

What is LTE?

• A work group established within 3GPP

• The next step in the evolution of 3GPP radio interface to deliver “Global

Mobile Broadband”

• A plan first conceived in 2004 that’s

• Based on clearly defined performance targets

• Based on clearly defined economic targets

• Based on improved use of the radio spectrum

• Based on simplified system design

• CA consists of

Component

Carriers(CC).

• CC are either

intra-band

(contiguous &

non-contiguous)

or inter-band.

• Current focus

on downlink

• We’ve gone digital…

• We’ve evolved to wideband radio

systems such as WCDMA and

more recently LTE with OFDMA

• During this period mobile phones

have evolved into handheld

computers with full multi-media

capabilities

• 2G, 3G & 4G will likely co-exist for

many years however the future is

4G with 5G coming along as and

when appropriate…
