How to Connect Port-au-Prince with a Wireless Network


As you can see from the network diagram above, Inveneo's long-distance WiFi links connecting NetHope member organizations is starting to be far-reaching. Inveneo engineers Mark Summer and Andris Bjornson have been able to bring high-speed Internet access - critical communication capacity - to eleven relief agency locations with minimal equipment and installation time

Our long-distance WiFi network has made huge improvements in connectivity for NetHope member organizations. Some had no connectivity before. Others had limited connectivity, like a 160 kbit connection that jumped to 1.6 Mbit. That’s like going from 3 dialup connections to a cable or DSL connection.


These leaps in access have immediate impact when 20-100 people are sharing bandwidth at each location. International staff are able to make high-quality Skype video calls when before even voice calls were next to impossible, cutting resupply and rebuilding times by weeks or months.

We want to do more than just build out physical infrastructure; we also want to build the human capacity of local Haitian companies. Eventually, we hope they can deploy these technologies themselves, expanding the benefits of ICT beyond Inveneo's direct reach.

While we're fundraising for long-term capacity development, we're going to start the process of knowledge dissemination with a primer on deploying long-distance WiFI links in Haiti

How to deploy long-distance WiFi links in Haiti

Inveneo has created a methodology for deploying long-distance wireless networks from our many years of work in Africa. So while Port-au-Prince presents it own set of logistical and communication challenges, we were able to install and manage a high-functioning network relatively quickly using these basic steps:

1. WiFi Network Design - make sure your nodes are visible to each other and pointing at the right location
2. Location Capacity Survey - confirming the location can support a network node
3. WiFi Hub Antenna Pointing - aiming the dish for the highest signal strength
4. Installation Trip Preparation - determining what you'll need before your 30ft up a tower
5. Node Antenna Setup - aiming and connecting the antenna
6. Disseminating Internet Access - networking locally for end-user access
7. Network Management - making sure everyone has equal access to bandwidth

If you've read this far, you'll want to read the full How to Deploy Long-Distance WiFi in Haiti primer and how we and our Certified ICT Partners can bring Internet access to rural and underserved communities in the developing world.

IPTV- Revolution in Television Market

Over the last decade, the growth of satellite service, the rise of digital cable, and the birth of HDTV have all left their mark on the television landscape. Now, a new delivery method threatens to shake things up even more powerfully. Internet Protocol Television (IPTV) has arrived, and backed by the deep pockets of the telecommunications industry, it's poised to offer more interactivity and bring a hefty dose of competition to the business of selling TV.



IPTV describes a system capable of receiving and displaying a video stream encoded as a series of Internet Protocol packets. If you've ever watched a video clip on your computer, you've used an IPTV system in its broadest sense. When most people discuss IPTV, though, they're talking about watching traditional channels on your television, where people demand a smooth, high-resolution, lag-free picture, and it's the telcos that are jumping headfirst into this market. Once known only as phone companies, the telcos now want to turn a "triple play" of voice, data, and video that will retire the side and put them securely in the batter's box. For More Info Visit.

Cisco's Telepresence - Death of Distance

The Cisco TelePresence On-Stage Experience was an ambitious collaboration between Cisco and Musion Systems, which took place during the opening of Cisco’s Globalization Centre East in Bangalore, India. Musion seamlessly integrated their 3D holographic display technology with Cisco’s TelePresence’s system to create the world’s first real time virtual presentation.

In the past, building and maintaining those critical business relationships meant expensive face-to-face engagement and productivity challenges, as well as mention time spent away from home and family.



Cisco TelePresence™ creates a live, face-to-face communication experience over the network that empowers you to collaborate like never before. Cisco TelePresence helps people meet, share content, create high-quality video recordings and events, consult with experts and deliver powerful personalized services, all using the power of the network for an immersive in-person experience.

Cisco demonstrated an "On-Stage" Telepresence experience at the launch of their Globilization Center East in Bangalore, India. During a presentation to the media in Bangalore, Cisco CEO John Chambers "beamed up" Marthin De Beer, Senior Vice President of Emerging Technology Group at Cisco, and Chuck Stucki the General Manager of the Telepresence Business Unit from San Jose. The photorealistic and lifesize virtual duo from San Jose then interacted with the Cisco CEO and presented to the audience in India.
