IDEA #3 – (”share my internet”)


I’ve written about this idea in the past (here and here). ShareMyWifi (I own ‘’ — “share my internet”) — Have you ever been somewhere and didn’t have an Internet connection (airport, hotel)? Or maybe you have the Internet connection and want to monetize it a bit (maybe you spent $6.95 for an airport wifi connection and would like to split that cost). Or you live in an area with tons of wifi Internet connections — and you’d rather not pay $50 per month for your own connection (or flip side of that coin).

My idea is that… you would install a piece of software on your computer — on your PC the software would sit in your system tray. The software would display other wifi Internet connections around you that are either free (open, unprotected) or that use (have this software installed and running). If you need an Internet connection, you are a buyer of wifi — if you have an Internet connection, you are a seller of wifi. There would be a credits/cost setup — if you share your connection, you’d either get paid cash or receive future credits on the system (when you lack an Internet connection) — if you need Internet, you’ll pay money. My business idea acts as the gateway and takes a cut of collected fees.

This is a software solution — there is a hardware solution that is trying to take off, but I think software is the optimal solution — tapping into using user wifi network cards. Apparently from what I’ve researched — typical wifi cards can only connect to one network at a time (or broadcast as a network). However, my research discovered that for Windows PCs — you could create a virtual device that would essentially make your computer appear to have 2 wifi cards in it (even though there’s only one). Thus, the one wifi card could broadcast you to the network — and the other wifi card would connect to someone’s Internet connection in the network. Thus, there’s an input and output network connection at this point.

If I need someone’s Internet connection, I connect to the network that person is broadcasting — and much like Wayport Internet connections (found at airport), every website I try to reach simply redirects me to a ‘’ webpage where I can purchase the Internet connection (maybe it gives me some information on the specific connection’s up-time and bandwidth speed. There would be certain service requirements — specifically up-time and bandwidth speed — or else the user is charged less (and the seller is paid less).

Another feature of this software might be that it bridges Internet connections together — thus, instead of connecting to 1 of the 4 available wifi networks — your connections are bridged to increase your speed from say 100 kbps to 400 kbps. See below:

Risks: Will the world eventually be blanketed by free wifi? Can Linux and Macs emulate a second wifi card?

Revenues: Sellers (“sharers”) of Internet connections get paid for sharing their connection — we collect all money and receive a percentage of the revenue collected on each sale.

From Corey Hickey, a consultant: Strictly speaking, wireless cards are only designed to handle one connection at a time. Microsoft’s Virtual Wi-Fi is an interesting idea, but it still operates by switching the wireless card back and forth between two networks.

They appear to have put a lot of thought into the idea, so it might be a viable approach, but I would be skeptic of its utility for routing until I see the results of such a test. Like the paper above mentioned, the crucial factor is the time it takes to switch between two networks. The paper says that, when using commodity hardware, they were able to achieve 300ms for connecting to an infrastructure network and 170ms for connecting to an ad-hoc network. That might be usable. I really don’t know. The trouble is that Internet communications require a significant amount of two-way negotiation, which would necessitate the wireless card to be constantly switching between the two networks. At best, latency would be like that of a slow dial-up connection, but bandwidth might be decent.
