This design win continues their success in this socket with a notable recent design win that includes the Samsung Galaxy SIII. Skyworks RF Front-end Module (FEM)
Antennas for iPhone Antennas are critical as they are the only way signals can enter and leave the phone If they are not effective your phone will not communicate well! Ideally the antenna should be efficient and radiate energy This is very difficult on a phone!!!
Antennas for iPhone
Famous example is iPhone 4
and “antennagate”
But Apple had a good idea
by putting the antennas outside
Antennas on mobile phones are
very poor (20% efficient)
Small and beautiful but
inefficient!
Hand and head also reduces
the signals
Need very careful designAntennas for iPhone
iPhone 5 keeps the external
antennas but fixes “antennagate”
I am sure Apple would have liked
to have a unibody design for the
entire phone

2500MHz – 2700MHzNetwork for iPhone 5 Concept #1: Radio Frequency and EM Spectrum Concept #2: Radio Propagation and Expensive Radio Spectrum Do you need to “see” the base station (transmitter) when you use your iPhone? Higher frequency (e.g. 5GHz) ~ Line-of-sight (LOS) propagation Lower frequency (e.g. below 2GHz) ~ Non-LOS propagation (diffraction and scattering) Radio Access Applications prefer NLOS!! limited spectrum available
More Network
What is LTE?
4G Cellular Networks Base Station
1.4MHz - 20MHz bandwidth
Voice / HD-Voice / Data [(DL) 100Mbps+ (UL) 75Mbp]
100km+ coverage; 500km/hr
Forth Generation (4G):- LTE
Cells
Third Generation (3G):-
WCDMA
Second Generation (2G):- GSM
First Generation (1G):- AMPS
Countries with commercial LTE servicemore Network
Why LTE is better?
(2) MIMO/OFDMA
– Improved Coverage
(1) MIMO
– Increased Capacity
Diversity
MIMO - Red + Blue = Double Bit Rate2 New apps in iPhone 5
Apple Maps
2D map, 3D map allowing flyover,
turn by turn navigation (with Siri),
Yelp integration
Getting better every day! :D

Keep in one place membership cards, coupons, tickets, boarding passes, etc.
Automatic update, e.g. notify you of your gate changes.
Location based, i.e. it pops up even on locked screen when you enter a shop.
Use Barcodes, instead of NFC (like your Octopus card)
Popular: Most existing smartphones have barcode app
Inexpensive: affordable by small business
Passbook is a platform, not a standalone app
Developer tools are available to allow new apps to interface with
Passbook, e.g. add a QR code coupon.

Currently, only a few companies’ apps are passbook-ready
but the list is growing fast:
US: Starbucks, Target, United Airlines; France: McDonald
China: Tencent’s QQ Movie Tickets, Ctrip, Baidu’s Qunar
H.K.: First use of iOS6 Passbook Boarding Pass - are airports

Novel 2D barcodes have been developed by my team.

Steve Jobs quoted, “People who are really serious about software
should make their own hardware.” Similarly, people who are
really serious about mobile software should develop apps using
the ECE knowhow behind.

Socializing using Siri
iPhone 5 display improvements 18% larger screen (but still not big enough: iP4 = 3.5”, iP5 = 4”, G = 4.8”) iPhone 4 = 64% standard color gamut iPhone 5 = 98% (72% NTSC) 52% reduction in glare reflection. 57% higher contrast in high ambient light
Resolution matters! 326 ppi (1136x640) retinal display, same as iPhone 4 True resolution G has 306 ppi in Pentile pixel arrangement, half number of R and B subpixels. Effective resolution is the same but in some pictures Moire is generated Very difficult to make small OLED pixels
Display Appearance Display thickness : 1.5mm (G: 1.1mm) Touch : in-cell (G: OGS), crisper image due to less overlay iPhone has more natural color. G has off white balance point (too much green) iPhone 5 has small color shift at large viewing angles. G has noticeable color shifts (OLED microcavity effect) Calibration : more accurate (Very mature LCD technology)
Why are we doing this? That iPhone 5 wasn’t cheap! The poor thing is in 20+ pieces now… The truth is that… We, the old Jedi, want to teach you to become a Jedi too… The next few slides are where the forces come together
