<small>These days every internet users use the word BROADBAND which is used to upload and </small>
<small>download more data like audio, video, photo…</small>
<small>Many internet users are switching to cable </small>
<small>modems and Digital Subcirber Lines to increase their bandwidth</small>
<small>There is a new type of service being developed that will take broadband into the air which is called as “AIRBORNE INTERNET”</small>
<small>The AI will function much like satellite based internet access without any time delay</small>
</div><span class="text_page_counter">Trang 3</span><div class="page_container" data-page="3"><small></small>AI is a private secure and reliable peer-to-peer aircraft communication network
<small></small>This implementation is used to connect aircraft to a groundbased internet access
node, including the information which passed across the communication link.
<small></small>It is useful in providing information about Weather, Surrounding airspace environment and for aircraft-to-aircraft communications
</div><span class="text_page_counter">Trang 4</span><div class="page_container" data-page="4"><small></small>Satellite internet replaces the dial up connection for telephone connection, cable connection for television.
<small></small>Satellite internet does not use telephone lines or cable systems, but instead uses a satellite dish for two way ( up and down) data communication.
<small></small>Upload speed is one-tenth of 5oo Kbps download.
<small></small>Download speed is 10 times faster than normal download
</div><span class="text_page_counter">Trang 5</span><div class="page_container" data-page="5">Two-way satellite consists of,
<small></small>Approximately a two-foot by three-foot dish,
<small></small>Two modems,
<small></small>Co-axial cables between dish and modem.

<small>1.</small> ANGEL TECHNOLOGIES planning AI called High Altitude Long Operation (HALO) which use fligth weight planes.
<small>2.</small> Aero Vironment has teamed up with NASA on a solar power unnamed plane that works similar to HALO
<small>3.</small> Sky Station International is planning for a similar thing using blimps instead of planes.
</div><span class="text_page_counter">Trang 7</span><div class="page_container" data-page="7"><small></small>The computer most people use comes with a standard of 56K modem, which means that copmuter has a downlaod stream at a rate of 56Kbps.
<small></small>Land based lines are limited physically in how much data that they can deliver because of the diameter of cable or phone line, but in AI there is no such physical limitation
</div><span class="text_page_counter">Trang 9</span><div class="page_container" data-page="9"><small></small>It takes only less time for AI to relay data that is not as high up.
<small></small>The AI aircraft will circle overhead at an altitude of 52.000 – 69.000 feet.
<small></small>These Airborne networks will overcome last-mile barries like physical proximity.
<small></small>This AI is not completely wireless, the consumers has to install an antenna on their home or business in order to receive signals from network hub over head.

passengers to access the internet at very high altitudes that is in aeroplanes and in other
conventional services.
