The Mesh Potato

Mesh Potato prototype

The Mesh Potato is a new device for providing low-cost telephony and Internet in areas where alternative access either doesn’t exist or is too expensive. It is a marriage of a low-cost wireless access point (AP) capable of running a mesh networking protocol with an Analog Telephony Adapter (ATA). Wireless APs such as the Meraki or OpenMesh (Accton Mini-router) APs are rapidly gaining in popularity due to their low-cost, relative robustness, and ease of installation. Adding the ability to plug an ordinary telephone into a device like an OpenMesh AP opens up very interesting possibilities.

Mesh Potato - Mock-up of final unit

Mock-up of production version of Mesh Potato

Here is the story of how the idea of the Mesh Potato came about.

The first prototypes (pictured at right) of the Mesh Potato were built in June of 2009, almost exactly a year after the Mesh Potato concept was conceived of. In late 2009, we launched a “beta” test of about 150 Mesh Potatoes in about 20 different countries. Based on feedback from beta testers and design refinements, the Mesh Potato will go into full production in September 2009. A web store will shortly be available on this site to accept order. You may pre-order Mesh Potatoes now through the contact page of this site.

You can see at the left what the production Mesh Potatoes will look like. More detail can be found in the Features and Specifications below.

Mesh Potato Features

Feature Benefit
Integrated Wifi and ATA in a single box Low power consumption, ease of setup, fewer cables, fewer points of failure, and low cost.
Mesh, Client or AP mode Wifi Can be a component in Mesh Wifi networks or connect to existing Wifi networks
One-IP configuration Set one IP and the device is ready to make an receive phone calls. Quickly build voice and IP networks and roll out a Wireless PBX in minutes.
Web GUI or Phone UI Configure via a web interface or telephone IVR menu. With Phone UI no laptop is required for on-site installation.
UV-resistant, weather-proof enclosure Long life outdoors, no need to purchase a separate enclosure for out door use.
Built in mounting points Simple and low cost outdoor installation.
Rugged design Withstands abuse that would destroy other products such as power surges, brownouts, reverse DC, over-voltage DC, and static electricity.
Wide range DC power supply Runs on any DC voltage from 10V to 40V, or any AC voltage from 110 to 250VAC via wall-plug type power supply. A solar panel can be directly connected – saving money on a solar regulator.
Power efficient Consumes just 2.5W (DC). Can run on a 10W solar panel.
Power over Ethernet (PoE) and Power over Telephone Line (PoTL) Just one cable run for both power and telephone. PoE and PoTL injectors included.
Open Hardware Design No vendor lock-in. Open to improvement by anyone.
Open Source firmware Linux, OpenWRT, B.A.T.M.A.N., and Asterisk. Stable, reliable community developed software. Open to improvement, adaptation, and innovation.
Asterisk Extremely configurable, add IVR menus, connect IP Phones and billing systems
