Single-Chip Dual-Band Combo 802.11n, Bluetooth 4.0 and FM

Multi-chip module aka SiP by Murata (iPhone 5 is thin and light…)

BCM4334 is fabricated using a low-power 40 nm RF-CMOS process from

TSMC and measures 4.07 mm x 4.48 mm. This design win continues their

success in this socket with a notable recent design win that includes the

Samsung Galaxy SIII.

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

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 design

Antennas 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

GPS and WiFi signals get

through the top and bottom

RF1102 SP9T switch for

tuning antenna to bands

700MHz – 960MHz

1710MHz – 2170MHz

2500MHz – 2700MHz

Network 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

First Generation (1G):- AMPS<Analog>

Second Generation (2G):- GSM<Digital>

Third Generation (3G):- WCDMA <Digital>

Forth Generation (4G):- LTE <Digital>

Base Station

Cells

Countries with commercial LTE service

What is LTE?

4G Cellular Networks

1.4MHz - 20MHz bandwidth

Voice / HD-Voice / Data [(DL) 100Mbps+ (UL) 75Mbp]

100km+ coverage; 500km/hr

more Network Why LTE is better?

MIMO - Red + Blue = Double Bit Rate

(1) MIMO

– Increased Capacity

(2) MIMO/OFDMA

– Improved Coverage

Diversity

2 New apps in iPhone 5

ECE Knowledge: Signal Processing, Wireless Commun., Networking

Apple Maps

2D map, 3D map allowing flyover,

turn by turn navigation (with Siri),

Yelp integration

Getting better every day! :D

GPS positioning

Ranging & Triangulation

WiFi positioning

Based on landscapes/

roadmap of WiFi signal

strengths

Offline positioning possible

Passbook APP 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.

PASSBooK READY? 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

Passbook Ready? http://www.youtube.com/watch?v=NqLLWh5JoXs

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 iPhone 5

socializing some more

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…
