14 Wireless Communication
� Transmisi suara dan data menggunakan
gelombang elektromagnetik menuju ruang bebas
� Gelombang elektromagnetik � Kecepatan cahaya (c = 3x108 m/s)
� Memiliki frekuensi (f) dan panjang gelombang (λ)
� c = f x λ
Modul 1 Pendahuluan
� c = f x λ
� Penggunaan frekuensi lebih tinggi umumnya medium meredam lebih besar

Pengkayaan Latar Belakang Sejarah Wireless � Perkembangan ilmu dalam bidang penjalaran gelombang elektromagnetik
serta pengiriman informasi
• Dimulai tahun 1867 James Clerk Maxwell : Penjalaran
gelombang EM pada ruang bebas udara.
• Tahun 1888 Heinrich Hertz : Percobaan radiasi energi
gelombang EM yang pertamakali
• Tahun 1892 Edouard Branly : Detektor radio yang pertamakali
History (0)
2/11/2010 21
• Tahun 1892 Edouard Branly : Detektor radio yang pertamakali
• Tahun 1895 Guglielmo Marconi pertamakali berhasil mencapai
komunikasi end to end wireless sejauh ¾ mil.
• Tahun 1901 manusia berhasil mengirimkan pesan trans atlantic
• Tahun 1906 Reginald Fessenden : Transmisi radio siaran yang
pertamakalinya
• Tahun 1933 Edwin Howard Armstrong menemukan FM (
Frequency Modulation )
• Perkembangan berlanjut dengan sistem yang makin kompleks

History (1)
� Two-way radios (known as mobile rigs) were used
in vehicles such as taxicabs, police cruisers,
ambulances, and the like
� Mobile/portable two-way radios

History (2)
� In December 1947, Douglas H. Ring and W. Rae
Young, Bell Labs engineers, proposed hexagonal
cells for mobile phones.[1] Philip T. Porter, also of
Bell Labs, proposed that the cell towers be at the
corners of the hexagons rather than the centers
and have directional antennas that would
24
and have directional antennas that would
transmit/receive in 3 directions (see picture at
right) into 3 adjacent hexagon cells.[2] [3] The
technology did not exist then and the frequencies
had not yet been allocated. Cellular technology
was undeveloped until the 1960s, when Richard
H. Frenkiel and Joel S. Engel of Bell Labs
developed the electronics.Modul 1 Pendahuluan

History (3)
� In December 1971, AT&T submitted a proposal for
cellular service to the Federal Communications
Commission (FCC).
� After years of hearings, the FCC approved the
proposal in 1982 for Advanced Mobile Phone
Service (AMPS) and allocated frequencies in the
25
Service (AMPS) and allocated frequencies in the
824-894 MHz band.[5]
� Analog AMPS was superseded by Digital AMPS in
1990.

1G
� NET in Tokyo Japan in 1979.
� In 1981 the NMT system was launched in
Denmark, Finland, Norway and Sweden. The first
handheld mobile phone in the US market was the
Motorola_Dyna 8000X, which received approval in
1983. Cellular networks with multiple base stations
26
1983. Cellular networks with multiple base stations
and protocols for the automated "handover"
between two cells when a phone moved.
� Analog, car phone, Motorola portable/hand held
phone. These systems (NET, AMPS, TACS, C-
Net, and Radiocom 2000) later became known as
first generation (1G) mobile phones.

2G
� In the 1990s, 'second generation' (2G) mobile
phone systems such as GSM, IS-136 ("TDMA"),
iDEN and IS-95 ("CDMA") began to be introduced.
In 1991 the first GSM network (Radiolinja) opened
in Finland.
� Digital NB, TDMA/CDMA, advanced and fast
27
� Digital NB, TDMA/CDMA, advanced and fast
phone to network signaling, higher frequency (900
MHz). In America the IS-54 standard was
deployed in the same band as AMPS.

3G
� NTT DoCoMo launched the first commercial 3G
network on October 1, 2001, using the WCDMA.
� In 2002 the first 3G networks on the rival
CDMA2000 1xEV-DO technology were launched
by SK Telecom and KTF in South Korea, and
Monet in the USA.

Monet in the USA.
� In March the first European launches of 3G were
in Italy and the UK by the Three/Hutchison group,
on WCDMA.

33 Frequency Carrier/Kanal
– Informasi yang dikirim menuju receiver dilewatkan pada
band frekuensi tertentu.
� Disebut sebagai kanal (channel)
– Tiap kanal memiliki bandwidth yang tetap (dalam KHz)
dan kapasitas (bit-rate)
– Band frekuensi yang berbeda (atau kanal) dapat
digunakan untuk mentransmisikan informasi secara
Modul 1 Pendahuluan
digunakan untuk mentransmisikan informasi secara
paralel dan independen (konsep multiple access).

34 Example
– Assume a spectrum of 90KHz is allocated over a base frequency b
for communication between stations A and B
– Assume each channel occupies 30KHz.
– There are 3 channels
– Each channel is simplex (Transmission occurs in one way)
– For full duplex communication:
� Use two different channels (front and reverse channels)
� Use time division in a channel
Modul 1 Pendahuluan
� Use time division in a channel
Channel 1 (b - b+30)
Channel 2 (b+30 - b+60)
Channel 3 (b+60 - b+90)
Station A Station B

35 Simplex Communication
� Normally, on a channel, a station can transmit only
in one way. � This is called simplex transmision
� To enable two-way communication (called full-
duplex communication)� We can use Frequency Division Duplex
Modul 1 Pendahuluan
� We can use Frequency Division Duplex
� We can use Time Division Duplex
What’s Frequency Division Time Division Time
Division and Time Division Multiplexing ???

A singe frequency channel is used. The channel is divided into time
slots. Mobile station and base station transmits on the time slots
alternately.

Channel Number Center Frequency (MHz)
Reverse Channel 1 <=N <= 799
991 <= N <= 1023
Forward Channel 1 <=N <= 799
991 <= N <= 1023
0.030N + 825.0
0.030(N-1023) + 825.0
0.030N + 870.0
0.030(N-1023) + 870.0
(Channels 800-990 are unused)
Channel bandwidth is 45 MHz

39 What is Mobility
� Initially Internet and Telephone Networks is designed assuming the user terminals are static
� No change of location during a call/connection
� A user terminals accesses the network always from a fixed location
� Mobility and portability– Portability means changing point of attachment to the
Modul 1 Pendahuluan
– Portability means changing point of attachment to the network offline
– Mobility means changing point of attachment to the network online

43 The Need for Wireless/Mobile Networking
� Demand for Ubiquitous Computing
– Anywhere, anytime computing and communication
� You don’t have to go to the lab to check your email
– Pushing the computers more into background
� Focus on the task and life, not on the computer
� Use computers seamlessly to help you and to make your life
