Piloting “White Space” to connect the underserved of rural Tanzania

Beyond the Net Journal

As economies develop in Tanzania, rural residents have growing needs for communication and broadband access. However, mobile operators are reluctant to invest in remote areas due to the elevated infrastructure cost and the high percentage of people that can’t afford the payment of the services.

The Internet Society Tanzania Chapter, supported by Beyond the Net Funding Programme in partnership with The University of Dodoma will target the remote areas of Dodoma Region, where conventional deployments are not available. Together, they will build a pilot project using TV White Space equipment as a community network solution.

White Space Internet is not widely adopted so far, but has the potential to transform the way we use wireless Internet. Being a free form of broadband, it is as a good alternative to provide underserved communities with Internet access that is similar to that of 4G mobile. White Space power stations can be charged with solar panels and broadband can travel up to 10 kilometers through vegetation, buildings and other obstacles.

“It’s amazing how life has changed in Tanzania thanks to the Internet”, explains Jabhera Matogoro, project manager and coordinator of Microsoft Innovation Center at the University of Continue reading

Mellanox, Ixia and Cumulus: Part 2

This post is part two of three in a series looking at the joint presentations made by Mellanox, Ixia and Cumulus at Networking Field Day 17, in February 2018. More specifically, this post looks at what part Ixia has to play in the deployment of an Ethernet switch fabric built using Mellanox switches and running Cumulus Linux as the Network Operating System (NOS).

Ixia

What confused me most about a presentation from Mellanox, Ixia and Cumulus about Ethernet fabrics was to figure out what role Ixia would be playing in the disaggregated model. Mellanox makes the switch hardware and Cumulus makes the switch software, so Ixia fits, well, where exactly?

IxNetwork

IxNetwork is billed as an end-to-end validation solution which in many ways undersells what it’s all about. Rather than being just more traffic-generating test equipment, IxNetwork can emulate multiple switch and server devices so that a single piece of test hardware can be connected to what it believes is a large existing infrastructure, and that hardware’s behavior and resiliency can be validated. In the demo topology, IxNetwork connects to a physical Mellanox Spectrum switch running Cumulus Linux, emulating connected servers as well as an entire leaf/switch EVPN/VXLAN fabric, attached Continue reading

Using Sales People for Tech Support is Expensive

First published in Human Infrastructure Magazine in Oct 2017. When something goes wrong with a product, your first stop is likely to be tech support. Those painfully expensive maintenance agreements that you pay for every year get you access to ‘world class’ support services. ORLY? Hopefully the problems occur after you bought and deployed the […]

What is DNS and how does it work?

The Domain Name System (DNS) is one of the foundations of the internet, yet most people outside of networking probably don’t realize they use it every day to do their jobs, check their email or waste time on their smartphones.At its most basic, DNS is a directory of names that match with numbers. The numbers, in this case are IP addresses, which computers use to communicate with each other. Most descriptions of DNS use the analogy of a phone book, which is fine for people over the age of 30 who know what a phone book is.[ Don’t miss customer reviews of top remote access tools and see the most powerful IoT companies . | Get daily insights by signing up for Network World newsletters. ] If you’re under 30, think of DNS like your smartphone’s contact list, which matches people’s names with their phone numbers and email addresses. Then multiply that contact list by everyone else on the planet.To read this article in full, please click here
