Martin V proposes dual WiFi/WiMax Router

Not everyone knows yet that fon’s president, Martin Varsavsky writes a frequent blog in multiple languages. While he does not always translate each entry to every language, occasionally English will get the scoop on the others.

Today he writes about taking initial steps to develop a fon-branded dual-WiFi/WiMax router! This is extremely exciting, since it promises far greater range, and potential meshability than 802.11a/b/g. Other abilities could include placing wifi hotspots where there is no wired internet connection available.

There is no word on which part of the world he would make the devices available, nor estimated price, but if this project goes through, we should hear more in the future.


Martin Varsavsky: “WiMax and Fon- Many people tell me that all is well with Fon until WiMax kills WiFi and then we will become obsolete. I think these critics don’t get it. WiMax comes in two flavors, proprietary bandwidth and public bandwidth. Fon is prepared for both. If it comes in open mode Fon is already in conversation with our Fonera supplier Accton to make routers that connect to DSL or Cable and send both WiFi and WiMax signal so we can give those out to Foneros and quickly deploy open WiMax. Also a WiMax enabled fonero will have so much more range! And if it comes in propietary flavor Fon will show operators that there’s a new way to grow a network, that living rooms can be more efficient than rooftops.”

WiMax/WiBro/XMax/UWB are related technologies in the sense that they use, or can be expanded to support wide bands of radio frequencies. This lets them simultaneously send and recieve on many “channels” at once, skipping frequencies which are reserved for other entities, and using a combination of licensed and license-free frequencies. An advantage of spreading the signal out over such wide territory is in increased speed, similar to the advantage of parallel transmission vs serial transmission.

Additionally, the power requirements are so low that this technology may even be allowed to use licensed frequencies without license if it proves that it does not interfere with stronger, conventional transmissions. I have also read that the technology which allows a WB base to separate all the noise from the low-power signal creates a virtual, highly-directional antenna between it and each client. This suggests that each client can use all frequencies at once without interfering with other clients nearby.

Let’s hope this new device has at least one LAN port on it for heaven’s sake! Other suggenstions i’ve written before for El Cheapo V2, if they build it:

  • needs built-in PoE (or suppy an adapter) so installation in areas without A/C power is easier.
  • needs suction cups on bottom of router to stick it up on the window.
  • needs at least one LAN port which can be optionally guarded by fon login page so hotspot can be expanded using additional WAP devices.
  • should position the WAN port on side opposite the antenna so it hangs down better.
  • supply larger, non-bendable antenna. cheaper with better reception.

    I read similar article also named Martin V proposes dual WiFi/WiMax Router, and it was completely different. Personally, I agree with you more, because this article makes a little bit more sense for me

    Martin has been talking about his La Fonera 2 (with USB port to use a thumb drive for bittorrent storage) for over 2 years now. I think any La WiMax Fonera is a long way off.

    Some people remain a bit confused about how it would work, and so was I for a while. WiMax will not be implimented as a sort of “really long range wifi”. It will not work in peer-to-peer mode or mesh. It will be a client-to-accesspoint structure like a cable modem, DSL or cellphones. Customers need an ISP to use it, and will only possess client equipment. The ISP will license spectrum and operate a network of base stations.

    Fon’s WiMax router would use WiMax as the “backhaul”; the source of Internet service, and will broadcast a conventional 802.11 b/g/n hotspot. Foneros will not use WiMax cards to connect to the hotspot. The Bill/Linus will need to have WiMax service in his area, to supply the backhaul.
