Where we are today
In 2002, there were 850M landline phones
As of 2015, there were over 7.4 Billion wireless subscribers worldwide.
– Current approximate world population: 7.4 Billion.
In the US (as of 2014):
– 90% have cell phones
– 65% have smart phones
– 35% go online mostly with a cell phone
Worldwide: By end of 2016 there will be more devices (7.9B) than people

Mobile Communications: Legacy
Cellular Telecommunications Network
W ireless Controllers
• Network tailored for voice – very low bandwidth
• Devices not suitable for Internet and computing applications
Despite high penetration & coverage, Internet fizzled until the mid-2000’s
Radio

The Internet – Wireless Enterprise Networks
Telephone Network
Radio Edge Access Internet Router Router
• Network tailored for best-effort data traffic – high bandwidth, no controls • Supports general computing and data networking applications
Now, ubiquitous coverage via 3G, 4G and WiFi
W ireless Gateways

 Hybrid architecture: evolved 3GPP & IP
 Control interfaces to support evolution are sophisticated by necessity
 Dependent upon access technology
 IP tunneling – GPRS Tunneling Protocol (GTP) within EPS
 Gateways – important part of evolved structure but introduce
throughput considerations and limitations 7

Information Centric Networking
• Usage and growth patterns require a change in the network
• Content and context aware message delivery is often associated with mobile services
• Complexities associated with legacy CS or PS drive paradigm shift
• Service typically involves dynamic binding of content/context to specific net addresses in conjunction with multicast delivery
• Retrieving information based on cached data enables scalability and reduces or eliminates complexity

Next Gen Mobile Networks: 5G – Mobile by Design
LTE w/FIA interface

Mobility-Centric Future Internet Architecture
Standard FIA Router
WiFi w/FIA interface
FIA Distributed Control Plane
 Unified Internet/Mobile Net arch with integrated support for naming, authentication, mobility, etc.
 Simplified distributed control rather than legacy complexity
 Technology neutral – BS or AP plug-in
 Flat network = No gateways or tunnels!
 Mobile devices as “first class” citizens

Overview of Traditional Wireless Networks
• Primarily wireless access to wired networks
• Feature additions over wired networks – wireless media
– mobility
• New features = New Problem (or new challenges!)

– data (packet access or circuit-switched)
• Wireless PBXs/LANs – 802.11
• Wide Area Data
– paging
– messaging
– access to the Internet
• Distribution – TV
18

Mobility Terminology
• Mobile Location
– Finding a mobile to deliver a connection/packet (LA/RA/TA) – Usually requires finding the cell in which a user is located
– Architecture design to provide area assignment
• Mobile Tracking
– Following the approximate location of a mobile as it moves while not in an active session – Usually involves some sort of registration
• Handoff (Handover)
– Transferring /forwarding a connection as a user moves while in an active session
19

Coverage Area
• Pico-cell (Femto-cell) – O(10s ft) – covers a room
• Micro-cell – O(100s ft) – covers a floor/street
• Macro-cell – O(10 mi.) – big towers
• Satellites
– regions/countries
20

Mobility
• Users can move great distances, at great speed, or both – personal mobility vs. terminal mobility
• High speeds while communicating
– cellular voice
– cellular data
– Doppler effects for wideband vs. narrowband
• Travel large distances between communication – cellular

Physical Layer
• Communications infrastructure is the air interface/frequency band – limited bandwidth
– shared, public media
– often regulated
– re-use of resources is key to providing sufficient capacity to users
• Harsh environment
– continually changing characteristics: adaptation – high error rate: FEC-based channel coding
– bursty errors due to sudden fades: interleaving – higher layer error recovery
• Mobility
– signal strength varies with location
– motion affects signals
– must “change” channels during handoffs
28

Physical Layer degradation
• Free space propagation model
– signal strength diminishes inversely with distance to the power n.
– n is typically between 2 to 4
– Free space propagation model predicts received power as inversely proportional to the square of the distance between transmitter and receiver
PTGTGRλ2 (4π )2 d 2
PR =
where GT and GR are transmitter and receiver antenna gains, r is the distance between the
transmitter and the receiver, and λ is the wavelength.
(λ = c/f where c is the speed of light = 3*108 m/s and f is the transmitted signal)
29

Power and Decibels
• Power has a large range over a typical coverage area – decibel is a convenient way to express this range
• Decibel expresses factors or ratios logarithmically
• For power ratios (dimensionless)
– X (dB) = 10 log (Y) For example, Y = 1000  10 log(1000) = 30dB – Y = (10 )X/10 For example, X = 30 dB1030/10 = 1000
• For power (Watt or Milliwatt)
– dBW (re:1W) and dBm (re:1mW)
– X (dBm) = 10 log (Y/1mW) For example, Y = 100uW10 log(10uW/1mW) = -20dBm – Y (mW) = (10 )X/10 For example, X = -20 dBm10-20/10 = .01 mW = 10uW
• Since the decibel scale expresses exponents, multiplying (dividing) factors corresponds to adding (subtracting) their dB values
30

Log-distance path loss model (Average Large-Scale Fading)
• Path loss is the difference (in dB) between transmitted and received power • Average received power decreases logarithmically with distance
PL =10log(P ) dB T
P
R PL(d)∝(d )n
0
PLdB(d)=PLdB(d0)+10nlog(d ) 0
n is the path loss exponent (2 for free space, 2-4 for cellular radio) and d0 is the reference distance close to the transmitter (usually 1m, but can be defined as other)
31

Physical Layer degradation (Small-Scale Fading)
• Multipath
Diffraction Reflection
T
Scattering
– Signal can get severely distorted due to reflection (objects larger than wavelength), scattering (objects smaller than wavelength), and diffraction (shadow fading)
• Rayleigh Fading (fast fading)
– statistical model of fading over the air
• Shadow Fading
– dependent on environment, signal variation has a log-normal distribution
• Inter-symbol interference (ISI)
– adaptive equalization techniques
32

Types of Small-Scale Fading
Based on Multipath Time Delay Spread
Flat Fading
1. BWsigBWchan
2. Delay spread > Symbol period
Based on Doppler Spread
Fast Fading
1. High Doppler spread
2. Coherence time < Symbol period 3. Channel variations faster than baseband signal variations Slow Fading 1. Lower Doppler spread 2. Coherence time > Symbol period 3. Channel variations slower than
baseband signal variations

Limits of wireless channel
• Shannon defined the capacity limits of communication channel with additive white Gaussian noise
•Forachannelwithoutfading,shadowing,ISI, themaximumpossibledatarateonagiven channel of bandwidth, B, is
C (bps) = B log2(1+SNR)
where SNR is received Signal to Noise Ratio
• This theoretical limit cannot be achieved in practice but novel design and coding techniques help data rates approach this bound

Channel Sublayer: Frequency Assignments

FDMA/TDMA systems
 Key: split spectrum into set of frequencies (channels) and reuse frequencies in distant cells=> careful frequency planning
Take advantage of frequency attenuation Dynamic channel allocation
CDMA systems
 Entire spectrum available to all cells (full re-use => little frequency planning)
 Capacity depends on interference level (soft capacity)
 Coverage is dynamic and depends on instantaneous number of users: “Breathing cell” => careful planning of thresholds and power levels
OFDMA (orthogonal FDMA)
 Combination of CDMA and FDMA

Frequency Reuse
• Each pattern represents a different set of carriers • Re-use factor of 3 shown
41

MAC Layer
• Maximize capacity and minimize delay (circuit vs. packet access)
– FDMA,TDMA,CDMA – for voice, streaming
– Aloha, Slotted Aloha – low delay for bursty, short messages (signaling)
– CSMA-based protocols – bursty messages, larger number of users
– Packet Reservation MA and other reservation-based protocols – bursty, long messages, large number of users
• Fairness/Quality of Service
– Don’t allow a user to hog bandwidth
– Schedule traffic to meet requirements
• Handoffs
– Assign new channels
42

Logical Link Control
• Error recovery
– yes or no (handled by TCP)? – ordered data delivery
43

Network Layer
• Responsible for routing
– circuit-switching: performed at connection establishment time – datagrams: performed or each packet
• Key problem caused my mobility
– address no longer = location to route connections/messages
• Address is a logical identifier • Ad hoc networks
– No infrastructure
– Self-organizing networks

• Each packet routed individually (potentially on different paths) • Hierarchical address (network + host) (not geographical)
46

Mobility and the Network Layer
• Circuit Switching
– address no longer points to location
– must find user once, then establish connection – connections must be updated for handoffs
• Datagram
– find user each time?
– smart solutions avoid this
47

Transport Layer
• Current data transport protocol (TCP) designed to work in fixed networks – establish end-to-end connection (in end points only)
– recover from errors
– flow control (react to congestion)
• Mobility causes problems due to errors or discontinuous transmission – may misinterpret lost packets
– may be affected by delay in locating mobile users
• Wireless Media – error rates
– low bandwidth
48

Applications
• Wireless media
– high error rates
– low bandwidth
– can high quality audio, video be supported? – can data applications be supported
• Mobility
– pauses in transmission
– possibility for new applications?
• Solution Techniques
– asymmetric design of applications and protocols
– network-based proxies to perform complex functions on behalf of mobile users – pre-fetching and caching of data
