Un modelo innovador de _tunnel broker_, implementado y ofrecido por AlterMundi, permite a las redes libres tener IPs públicas globales, manteniendo latencias bajas en la comunicación con otras redes participantes. La propuesta simplifica la administración de rangos IP dentro de las redes, al mismo tiempo que permite acceder y publicar contenidos en la _Internet v6_.

Doing _Power-over-Ethernet_ on a Gigabit port might seem challenging at first sight: since all 4 pairs of UTP are used as data lines, there are no «spare» pairs to use exclusively for sending DC current, as in 100mbit ethernet cables.
However, it’s possible to inject (and extract) DC voltage _on the data pairs_, using *center-tapped transformers*, preserving the signal transmission intact and the gigabit speeds of the port.
Most CPEs and outdoor equipment support PoE out-of-the-box, and come with a PoE injector so that you can run a long length of UTP between the power source and the equipment.
Most SOHO routers don’t come with this feature, but with a few tools, minimal soldering skills, and 10 spare minutes, you can pull out this hack and obtain more flexibility than most CPE solutions offer.
The routers used for this test are TP-Link WDR3600 using AlterMesh based on OpenWRT r33815. This router is a multi-band model which works simultaneously on 2.4Ghz and 5Ghz. It is MIMO 2×2. The routing protocol used is batman advanced 2012.4.0.
