Recent technological advances allows anyone to start their own cell phone company, also known as a Micro Telecommunication Company (Microtelco). With some technical knowledge and a crafty spirit you can be well on your way to becoming the next AT&T.
This document will explore why, where, and how you might start a cell phone company. Although be warned the Microtelco business has many legal hurdles, including strict regulations regarding the use of cellular radio waves. I will suggest ways to circumvent these laws, and create a Microtelco as viable private small business, or part of a community venture.
Mobile Phone Statistics
Cellphones are Everywhere
There is a very good chance that everyone you know owns a cellphone. Even in places with inadequate service or where people make less than $2 a day, most people own a cellphone. The cheapest cell phones have a calculator, games, radio, and sometimes even a flash light. In many poor regions phones are one of the few entertainment devices that people save money to purchase. Also many of the poor regions have inadequate service or no service at all. This is perfect place for Microtelcos to exist. While large Telecommunications companies may not be able to justify their expenses for installation of their expensive cellular network, which can cost upwards of $50,000 - $100,000 for each installation, Microtelcos can use low cost cellular installations to provide basic communication services.
The Caribbean Coast of Central America, and much of South America lack adaquate cell coverage. Click link below to view interactive world map of cellular coverage.
The pricing of cell service varies greatly throughout the world. Many Latin American countries lack of competition in cellular providers and therefore have higher prices. In Mexico there was a landmark legislation that will break up Telmex, a company that currently has between 70-80% of Mexico's phone market. Telcel, whose majority owner Carlos Slim, is also majority owner of America Movil which operates in 16 Latin American countries. In Nicaragua, Claro (an America Movil subsidiary) has a virtual monopoly over large regions of the country. Recent regulation in Mexico have opened the door for competition in the Telecommunication sector in Latin America. Aided by innovation in low cost cellular hardware, Microtelcos, can play an important role in increasing access and affordability to rural and underserved regions of Latin America.
The high price of service has a real effect on the poor. In Nicaragua and Brazil the average person has to work 2 hours in order to afford a ten minute phone call. Yet in other countries, cell prices are significantly lower. This proves that there is a need to lower prices especially in poor regions, and this can be accomplished through introduction of competition in cellular providers.

In 2010 two open source softwares where created that emulated the BTS Station, the hardware used to create a cellular network. The first Osmocom (osmocom.org) created by Harlde Welte, and the second was OpenBTS (openbts.org) created by Harvind Samra and David A. Burgess. In 2013 Burgess left the Range Networks, the company that grew from OpenBTS, and started a new prokect known as YateBTS (yatebts.com).
Osmocom, OpenBTS and YateBTS still are activly developed and updated. Osmocom is the only fully open source project. OpenBTS and YateBTS have parts of their software that is open source and proprietary. They all used software defined radios. A software defined radio is a communication system that takes components that traditionally where hardware (amplifiers, mixers, filters, modulators, etc), and are implemented with software that is handled by the processing power of a personal computer.
The key to creating you own cellular netork is to have a SDR that is equiped to handle Radio waves in the cellular spectrum.
Ettus was the first company to offer SDRs, but many hardware solutions have been released in recent years.
There is also a new crop of cellular BTS box that claim to be easy to deploy, without the need of learning Unix based programming. The includes Endaga (endaga.com) , Fairwaves (Fairwaves.co), and VNL (vnl.in).
There are quite a few real world deployments of low cost cellular networks. The largest is in Mexico with the non-profit Rhizomatica (rhizomatica.org). They have 10 locations through out the state Oaxaca. They are schedules to have 15 by the end of 2014, and have been given a consecions to operate in the region by Telcor, Mexico's Telecommunication borad. Originally they operated without a liscence in working with community radio stations in Indegenous communities that did not have any cellular provider. The legal argument was that if no service was avaliable, then the use of the cellular spectrum did not impeed on the commercial companies that held the rights to the spectrum. Furthermore these cellular networks are owned and opperated by the community, with Rhizomatica only installing equipment and providing support.
Endaga also has a deployment in Papua New Guinea. OpenBTS has been used at Burning Man, and there is an installation in Antartica.
Rugged Communication (ruggedcommunications.com) has a deployment in Western Panama.
So you want to start a Cellular Network? Well the cost of all the equipment is about $6000-$10000. I will update with a comprehensive list of equipment, but you can also contact Fariwaves, or Endaga and they will provide you with a quote, and help you figure out your specific needs for the region you are setting up your GSM network. For regulations its best to work in regions that dont have any celular network, or find a part of the spectrum that is not currently in use. Also working with the community, or community government has proven to work in Mexico, and in Panama.
If you want to start experimenting the cheapest SDR (Software Defined Radio) card can be purchased from nuand (nuand.com). They produce the BladeRF ($420), and they have a partnership with YateBTS. Nuand claims their card can do 4G as well has handle over 200 call simultaneously. Ettus has several cards you can buy starting at ($700)USRP1, but this hardware requires modification to the clock hardware. YateBTS, OpenBTS, and Sysmocom(Osmocom) both have a development kit that can be purchased for $2000.
In terms of software stack, Rhizomatica uses the Osmocom, which they claim is very stable. And they are running various networks, so they must be doing something right. They also have a good team of developers provide some support when they have time. They are a great non-profit and pioneers in the Micro Telco Industry.
