Last three years in ME

• WiFi Zones
• Public Areas applications (BurJuman)
• WiFi Phones
• Fixed Wimaxed links.
• Triple Player (Video, Data Voice) over
  wireless.

15
Wi-Fi Hotspots at 40,000 feet height

• Time, for many of passengers, definitely is
  money.
• Many of airlines understanding this need,
• Emirates is the first airlines in ME has invested
  in the WiFi hotspot.

16
WiFi Hot Spots

• Coffee Shops
• Airports
• Railway stations
• Hospitals
• Public areas
• ..

 
17
Digital Cities (Open Access WiFi)

• San Francisco
• Moscow
• Rwanda
• Sidney Gardens
• Los Anglos
• Riyadh
• Philadelphia
• .

WiFi , RFID NFC
19
WiFi , RFID NFC

• NFC offers a simple, touch-based solution that
  allows consumers to exchange information and to
  access content and services in an intuitive way.

20
NFC Applications

• Can be used (Pay phone or Data retriever)
• in
• Car Parking
• Super Markets
• Petrol Stations
• Public Areas ..
• ..

Pay Phone
City of Caen, France, to demonstrate simplicity
of Near Field Communication (NFC) technology

Mosquito-FiMosquito catching over Wi-Fi

• Its an electronic vacuum cleaner that omits
  odors attractive to mosquitoes.
• better to kill mosquitoes before they breed!

22
WiFi Against Mosquito rights group

• We've meshed a great mosquito-catching machine
  with a computer technology on top of it, and
  wireless network technology on top of that, and
  then turned it into a great defensive shield
  against mosquitoes coming into your habitat
  Devin Hosea, AmBio CEO
• So far we don't know of any mosquito rights
  group, so it's totally PC to kill as many as you
  want Devin Hosea, AmBio CEO

Why are we interested in WiMAX?

• bandwidth
• QoS
• services
• standards
• and a rural model .

WiMAX Access Application

26
WiMAX/3G Debate

• Is WiMAX a threat to 3G ?
• Voice networks backhauls.
• Mobily Case in Saudi
• Data Service Providers

27
IEEE / ETSI Standards

Solar powered WiMax

• solar-powered WiFi router/WiMax
  router/surveillance cam that can be situated a
  top a streetlight. The access point may uses a
  high gain omni antenna and a high gain parabolic
  antenna to provide access/security to both
  developed and developing regions it is already
  in use in Cameroon, with plans for deployment to
  India, China, and Morocco.

31
WiMAX Fixed, Portable Mobile

• Fixed LoS, nLoS NLoS.
• Portability samples
• ATM machines, Railways, Riggs, Cruisers, TV
  broadcast services,
• Mobility on board.

32
WiMAX Planning Designing

• The major challenge for WiMAX designing in ME is
  GIS availability.
• Satellite service provider.

OFDM OFDMA

• OFDM is a modulation techniques related to Fixed
  and Portable scenarios.
• Uses 256 point FFT (Fast Fourier Transform) _at_
  demodulate the signal.
• All subcarriers transmitted at once.
• Same modulation type is applied for all channels.

OFDM Modulating for 9 subcarriers
FDM Demodulating for 9 subcarriers
36
OFDM OFDMA

• OFDMA is a modulation techniques related to
  Mobile scenarios.
• Uses 2048 or 4096 point FFT (Fast Fourier
  Transform)
• _at_ demodulate the signal
• Subcarriers transmitted separately.
• Interference prevention.
• Different modulation type can be applied for
  every channel (QPSK, 16QAM or 64QAM)

37
How to protect your WiMAX investment?

• Moving from Fixed to Portable to Mobility WiMAX.
• Is your box firmware upgradeable?
• Minimize the IF cable as much as you can.
• use 5.4 GHz domain instead of 5.8 GHz.

38
Smart Antennas Designing

• because the available broadcast spectrum is
  limited, attempts to increase traffic within a
  fixed bandwidth create more interference in the
  system and degrade the signal quality

Will Mobile WiMAX Kill Wi-Fi?

• The approval of the IEEE 802.16e standard for
  mobile WiMAX raises many unanswered questions
  about the future of Wi-Fi.
• About 90 of laptops are now delivered with
  built-in support for Wi-Fi.
• The number of public Wi-Fi hotspots continues to
  grow.
• Mesh WiFi will be deployed 2006/2007

Mobile WiMAX wont kill Wi-Fi
Competitive, But Not a Replacement

WiBRO 2006 _at_ Korea
44
WiBRO 2006 _at_ Korea

• Wireless Broadband Access, part of the IEEE
  802.16 family.
• 2.3 GHz closely related to the mobile WiMAX.
• WiBro rollout this year _at_ South Korean.
• Keep 1 Mbps for mobile user.
• WiMAX (Fixed) to backhoul the Wibro network.
• Samsung has demonstrated a 4 Mbps download and 2
  Mbps upload.
• Samsung announced a cell. Phone PDA with WiBro
  capabilities.

MAKKA Case Study
46
MAKKA Case Study

• Ministry of Hajj in Saudi
• To cover the whole Makka area wireless.
• More than 450 offices to be connected.
• Mena Arafat second phase coverage.
• Smart automated system to manage the Hajj season.
• WiMAX / WiFi application

DWC - RESULTS

• Every Student has a Lap Top
• Approx. 2500 Wireless Devices
• WLAN Signal blankets the campus.
• Every classroom (130) ms access to the Intranet
  and Internet
• Internal resources have been reallocated

Conclusions

• WiFi applications to continue over 2006/2007
• Riyadh to be the 1st digital city in ME.
• RFID NFC are grow on.
• WiMAX thread to 3G.
• Solar Powered outdoor bridges will increases the
  mobility wireless access deployment.
• Mobility features amended in 802.16e are still
  not specified and not fully standardized
• OFDMA decrease the interference for mobility
  WiMAX.
• Be sure that your WiMAX hardware is firmware
  upgradeable.
