Developing countries have always had various challenges for mobile operators and other telecom companies to overcome. Some of these include lack of or substandard infrastructure, political uncertainty, regulatory issues, challenging environments, vast and sparsely populated geographical areas to cover, unreliable energy supplies, poorer target groups, etc.

However, these challenges have been overcome with ingenuity and perseverance. In many countries, prepaid cards in small denominations sold in numerous mobile booths have given consumers with little money access to mobile telephony. Off-grid base stations in Asia, the Middle East and Africa are increasingly using green power solutions almost completely replacing the use of dirty and expensive diesel. In East Africa, M-PESA and other mobile money systems have revolutionised the way money is transferred, making it possible for almost everybody to use basic banking services.

Developing countries are next in line experience exponential increase in data consumption. So when the developing countries take the next big step into the "post-mobile data revolution", there are going to be a number of challenges to overcome. The penetration of data in many of these markets is still low and prices are still high. And even if everybody agrees that data will take off in a big way, it is difficult to predict when it will happen and how fast. Can you best prepare to quickly respond to the anticipated demand without investing too much too early? The biggest challenge is infrastructure. High quality, efficient data centres are essential. They house and power all the equipment needed for transmission of data and are both the heart and brain of any network. But traditional builds for data centres take a lot of time to plan, co-ordinate (with different suppliers) and construct. Furthermore, challenging environments add a lot of risk to a data centre project, often resulting in delays and budget over-runs. Buildings for data centres are often not purpose built to be used as technical facilities, often with water leaks and other problems, as well as being over-dimensioned since they cannot be expanded quickly and easily.

Pre-fabricated modular data centres ideal for emerging markets networks. They are quicker to deploy and will in most cases save considerable time and money compared to traditional brick and mortar buildings. The facility will always be the "right" size since its modular structure makes it easy to quickly expand in response to changing needs. More efficient power and cooling will make a pre-fabricated data centre more cost effective to run. And quality, budget and the time plan can more easily be ensured for pre-fabricated purpose built facilities, bringing predictability to the project. A pre-fabricated solution also makes it much easier to customise the data centre for specific needs and it can be deployed anywhere.

Let us take a look at a live example: Vodacom in Mozambique (a subsidiary of Vodafone) recently decided to deploy a modular data centre (the eCentre) on top of a six-storey parking garage next to its corporate headquarters in central Maputo, the capital of this southeast African country. The roof top turn-key deployment is a 126 square meter open space data centre. Vodacom needed to put the facility in place quickly, efficiently, and on time. The pre-fabricated build reduced the project risk significantly because the construction work was all done in ten weeks in a clean environment (in Sweden) and the installation work needed on site was completed in only eight days, in total a fraction of what a similar local brick and mortar project would have taken.

Speed and predictability in challenging environments are critical issues in Africa considering it is the fastest growing mobile market in the world and the take off for data could be right around the corner. Pre-fabricated, modular and custom-designed data centres that can be deployed very quickly, and easily re-deployed if needed, is yet another innovative solution to an African problem (or rather African situation, since there is nothing problematic with fast growth). It is a solution that will allow data centre owners - internet service providers, hosting companies, mobile operators and banks - in developing countries to act quickly and confidently towards a demand for data that might be stronger than any of us expect.
