Bandwidth is the amount of data that can be exchanged between systems.
bandwidth is the amount of "internet" one can use.
Just like on steemit, you have bandwidth which is a measure of How much of activities you can carry out. It can be used up.
I hope you never be in that position when your bandwidth is exceeded and you have huge value you want to pass across.
BandZ was created in the mid 2017, with one purpose, which is to decentralize the internet. The internet enabled the blockchain, now, BandZ is putting that power to control the internet through blockchain technology in your hands.
Bandz is a global, blockchain based extranet. it allows each user to act as an intranet and then make internet available and much more affordable for the end users.
Extranet is a secure network, with users on it, that allows information to be exchanged.
Bandz makes enterprise-grade tools and service available to novice and inexperienced users at affordable prices.
These services will be made available on the BandZ network, and the exchange currency will be the BandZ token
The aim of BandZ is to make each end user, an internet provider.
Here in Nigeria, imagine instead of having to subscribe for internet packages, you have the power of an internet service provider. sounds so good to me.
A whole lot of nodes, connected together, set as mesh networks, providing internet services for users. not only will this solve the problem of maintenance cost, but also that of reliability and responsiveness.
The internet as a company keeps the world out, but the intranets are likened to portals, through which you can have access to internal and external resources. i read this from 
The purpose of blockchain is to empower the people, the community. Bandz has brought the power of ruling the internet into the hands of the community. with bandZ, each user becomes a node, and when connected together, we have an infallible mesh network. Where you will have access to the internet. even if one node fails, there are more than enough to respond to you.
Bandz saves you the stress of poor service delivery by ISPs and can also earn you more, like the two cases sighted by @Originalworkss.
It also ensures security. With band, the cost of maintaining or being an ISP is reduced if you install BandZ SDK on your device. Also, for end users, it makes the internet service more cheaply affordable. it gives the power of the internet to a community rather than to an group of people.
Decentralized internet means the power of information in the hands of people. nothing is more amazing than that.
Here in Nigeria, we buy internet services very costly. Sometimes, they sap the internet package i bought like i never even bought at all. I am a newbie to programming. i do self taught classes offline. i download videos and then study at my own time. Presently, my classes have been slow because i need a large amount of data to download videos from the web.
My programming videos are low quality because i have to be economical and with the number i have, i have about 30G size occupied only by programming videos. That has cost me a fortune to download. but with the advent of BandZ, i can download more with less and definitely high quality.
I will master my programming and then be able to teach other and earn more using BandZ and Programming.
Who can benefit from being able to exchange bandwidth?
wow. a whole lot of people can do that. cooperate organisations, business starters, imagine me being connected to a big time programmer, i can exchange codes with him and learn directly from him.
everybody and anybody, can benefit from this. both users and nodes, generating income through tokens and also vital informations which most times, you wouldn't have access to.
How can BandZ get rid of needless roaming charge?
For people who travel a lot, this is a great blessing. Because with mesh, you can carry the experiences of where you are coming from, to where you are going.
some have to change sim cards when changing location, which leads to loss of contacts or total break in communication sometimes. With Bandz, roaming charges are curbed because all i need to do is to connect to the bandz network, and i am home even though am away. no need searching for WiFi hotpots. i can even become a hotspot and be making my own money. also, i can do video and voice calls and be with the ones i love.
I imagine a better communication between board members having meeting at the same time, but different locations.
