Making Mobile Networks Cheap and Green

VNL of Sweden unveils a solar-powered base station for the cellular industry that is a fraction of the size and cost of conventional towers.

It has taken 21 years to get mobile phones into the hands of 3 billion people around the world. Reaching the next 1.5 billion, who live in the world's poorest and most remote corners, is expected to take a lot less time but will pose much tougher challenges.
There is, for instance, the thorny question of how to justify the expense of installing transmission towers in areas where people can only afford to pay as little as $2 per month for phone service—not to mention the cost of running and servicing equipment where electricity and engineers are in short supply.
That is where VNL, a new, privately funded Swedish-Indian telecom equipment maker comes in. Co-founded by Anil Raj, a Stockholm-based mobile industry veteran who held key roles at Ericsson and Sony Ericsson, VNL includes a dozen of the engineers and executives who created the digital-mobile technology known as GSM. They have turned their expertise to the challenge of making mobile networks that are vastly cheaper, simpler, and less power-hungry than anything ever before devised.
The Four-Year Wait is Over
Now, after four years in stealth mode, VNL is finally pulling back the curtain. In July, the company introduced its radically new mobile transmission towers—known in industry parlance as base stations. Costing just $3,500 each (compared with prices typically ranging from $10,000 to $100,000 for conventional base stations) and roughly the size of a laser printer, VNL's base stations are powered by solar energy and use only as much energy as a 100-watt lightbulb. That's one-sixth the amount needed by the most efficient competing base stations that run on alternative energy.

COMENTÁRIO: O artigo apresenta um caso muito interessante no qual a energia solar não só é viavel, mas permitiu reduzir drasticamente o custo das torres de transmissão de sinal de celulares.
