Wi-Fi Hotspots at 40,000 feet height

• Time, for many of passengers,

definitely is money.

• Many of airlines understandingthis need,

• Emirates is the first airlines in

ME has invested in the WiFi

hotspot.

WiFi , RFID & NFC

• NFC offers a

simple, touch-

based solution that

allows consumersto exchange

information and to

access content andservices in an

intuitive way.

Mosquito-Fi

Mosquito catching over Wi-Fi

• It’s an electronic vacuum

cleaner that omits odorsattractive to mosquitoes.

• better to kill mosquitoes

before they breed!

WiFi Against Mosquito rights group

• “We've meshed a great mosquito-catching machine with a computertechnology on top of it, and

wireless network technology on topof that, and then turned it into agreat defensive shield againstmosquitoes coming into yourhabitat” … Devin Hosea, AmBio CEO

• “So far we don't know of anymosquito rights group, so it'stotally PC to kill as many as youwant” … Devin Hosea, AmBio CEO

Solar powered WiMax

• solar-powered WiFi router/WiMaxrouter/surveillance cam that can besituated a top a streetlight. The access

point may uses a high gain omniantenna and a high gain parabolicantenna to provide access/security toboth developed and developing regions;it is already in use in Cameroon, with

plans for deployment to India, China,and Morocco.

OFDM & OFDMA • OFDM is a modulation

techniques related to Fixedand Portable scenarios.

• Uses 256 point FFT (Fast

Fourier Transform) @

demodulate the signal.

• All subcarriers transmittedat once.

• Same modulation type is

applied for all channels.

OFDM Modulating for 9subcarriers

FDM Demodulating for 9

subcarriers

8/4/2019 A a Faq 07


OFDM & OFDMA

•OFDMA is a modulation techniques

related to Mobile scenarios.

• Uses 2048 or 4096 point FFT

(Fast Fourier Transform)

@ demodulate the signal

• Subcarriers transmitted separately.

• Interference prevention.

• Different modulation type can be

applied for every channel (QPSK,

16QAM or 64QAM)

How to protect your WiMAX investment?

• Moving from Fixed to

Portable to Mobility WiMAX.

• Is your box firmwareupgradeable?

• Minimize the IF cable as

much as you can.

• use 5.4 GHz domain instead

of 5.8 GHz.

Smart Antennas Designing

• because the available broadcast

spectrum is limited, attempts to

increase traffic within a fixedbandwidth 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-insupport for Wi-Fi.

• The number of public Wi-Fi hotspots continues to grow.

• Mesh WiFi … will be deployed 2006/2007

Mobile WiMAX won’t kill Wi-Fi

Competitive, But Not a Replacement

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.
