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
localities
Ubiquiti 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.
New large-scale cheap wireless projects everywhere in the world
Cheap wireless devices like 3G mobile cellular phones
Enviro-friendly projects approval in most countries are getting the node
ahead of the opposite
Tried and tested
Hardware costs
Support is always available on their website http://www.ubnt.com
Wi-Fi certified and compliant devices are installed in many
personal computers, video game consoles, MP3 players,
smartphones, and other peripherals
Some 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
ACTS 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 large
A 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 user
The 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.
Another 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 kilometers
The standard IEEE 802.11 protocol stacks can also be modified to make them
more suitable for long distance-protocol hacking
Constistent use of the The Ubiquiti Networks Wiki
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 area
Always have working spare parts ready and remember to follow-up on
warranties
Have routers which incorporate a DSL-modem or a cable-modem and a Wi-Fi
access point
Have two ISPS
Backup all data and store it in secure onsite or off-site locations which are
easily accessible when needed
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.
Convenient
Most devices are wireless compatible now
Data mobility
Capacity building and less donor depends syndrome
Uses of the wireless technology is changing lives
Small business and home networks are increasing everyday
Many companies are using Wifi antennas for different business endeavours
Multihop WiFi antennas are creating longest network of the world either for
intenet connectivity or radio services
These antennas can help in disaster prone areas like Victoria outbacks for
disaster alerts
Natural disasters like Lightning
Electricity
Area’s geological lay out
Internet cut-off
Managing the bandwidth
Human induced emergencies Theft
Customs Traditions
Cost
