1RESEARCH AND EVALUATE UBNT WIFI ANTENNA FOR A 5 KM WIRELESS LINK EXTENDING ADSL TO A SMALL BUSINESS In this presentation I will show how the UBNT Wifi Antenna maybe used by small businesses or government agencies mainly in the developing world to extend the availability of internet services to rural and remote underdeveloped localitiesUbiquiti Networks designs, manufacturers, and sells innovative broadband wireless solutions worldwide. The company's products include disruptive outdoor wireless products such as the The Bullet (TM), NanoStation (TM), and others; which combine industry leading product design built around internally developed core technologies including the AirOS operating system and Frequency Freedom technology (100MHz to 10GHz) RF design.

3THE USE AND RISE TO PROMINENCE OF THE UBNT WIFI ANTENNA
4Why UBNT wifi Antennas?New large-scale cheap wireless projects everywhere in the worldCheap wireless devices like 3G mobile cellular phonesEnviro-friendly projects approval in most countries are getting the node ahead of the oppositeTried and testedHardware costsSupport is always available on their website
5Examples of usesWi-Fi certified and compliant devices are installed in many personal computers, video game consoles, MP3 players, smartphones, and other peripheralsSome of UBNT wifi antenna can be used as Outdoor Radio Device Wi-Fi is used for low-cost, unregulated point-to-point connections, as an alternative to cellular networks or satellite links.150+Mbps of real outdoor throughput and up to 20km+ range.PowerStation features exceptional radio and antenna design which allows links to be established over distances of 50km
6Case StudyACTS Clinic, a non-government HIV/AIDS clinic in the Masoyi Village near the Kruger National Park in South Africa, is also at the hub of an information and communication project supported by the IDRC. The project team put the infrastructure in place to cover the Valley with connectivity, with the clinic as the central hub for the initiative.The focus is therefore on the ACTS clinic and the strategies to enhance the use of the network in this situation, before dealing with the expansion to other clinics and the community at largeA community-owned mesh network with built-in redundancy has been created in a deep rural setting with a number of topographical constraints. It has been possible to spread the applications over a range of users, from the clinic to a hospice, to framers, to the school and individual userThe main challenge is the exit strategy that needs to be put in place for the researchers to be able to withdraw and leave behind a workable and viable ICT network in its current setting. The Valley mesh network makes use of a commodity low cost WiFi based router,This network diagram shows the current connectivity between all the nodes in the mesh network and some of the servers and devices that have been installed. As can be seen from the above diagram, there is a fair amount of redundancy in the mesh network, for example, if Sakhile school goes down, network can still reach Agnus' house via the Kok farm.
9Quality PlanAnother way of adding range uses a power amplifier. Commonly known as "range extender amplifiers"Specially shaped directional antennas can be used to increase the range of a Wi-Fi transmission without a drastic increase in transmission power.High gain antenna may be of many designs, but all allow transmitting a narrow signal beam over distances of several kilometersThe standard IEEE protocol stacks can also be modified to make them more suitable for long distance-protocol hackingConstistent use of the The Ubiquiti Networks Wiki
10Disaster Recovery Plan If the disaster is naturally caused the best is to involve all Emergency agencies in the area.Increase the wireless access point for high redundancy levels in the areaAlways have working spare parts ready and remember to follow-up on warrantiesHave routers which incorporate a DSL-modem or a cable-modem and a Wi-Fi access pointHave two ISPSBackup all data and store it in secure onsite or off-site locations which are easily accessible when needed
11Benefits of this technology in these areas Cheap and easy of access to information even in remotest area (tidal fading-where point-to-point wire- less links are deployed at low altitudes over tidal estuaries, multipath interference from reflections over tidal water can be constructive at some states of tide and destructive at others.)Bring Internet to a home if regular cable/DSL cannot be hooked up at the location.If you are moving to a new location, you can transfer the interface and install it at your new location easily.There is no need for an Ethernet cable to connect computers to each other.ConvenientMost devices are wireless compatible now
12Lessons Learnt Data mobility Capacity building and less donor depends syndromeUses of the wireless technology is changing livesSmall business and home networks are increasing everydayMany companies are using Wifi antennas for different business endeavoursMultihop WiFi antennas are creating longest network of the world either for intenet connectivity or radio servicesThese antennas can help in disaster prone areas like Victoria outbacks for disaster alerts
