Cellular
networks rely on radio towers or base stations that convert electricity into
radio waves and need a constant supply of energy to operate. In developed
areas, base stations are easily connected to a main power grid for a reliable
energy supply. In developing areas however, 1.6 billion people lack access to
grid electricity and an additional one billion people have unreliable
electricity. Though providers have relied largely on diesel powered generators to power off-grid and unreliable grid
base stations, it is becoming increasingly apparent that this is not the optimal
solution for off-grid power.
Mobile Communications is one of the great
means of information sharing and knowledge acquisition. Unfortunately, the 1.6
billion population of the world do not have this luxury. In today’s world
access information is essential for economic growth, yet a study by Deloitte1
commissioned by the GSMA (GSM Association) suggests that access rates in developing
countries often lag more than 20 years behind those in the developed world
[12]. To address this challenge, GSMA launched a program called Green Power for
Mobile (GPM) program in September 2008 to “extend mobile beyond the grid.” In
just over a year reasonable activities have to take place across the world to
make it a reality. Thus, the mobile industry is in a great position to reduce.
Kirloskar
has announced that the Georgia Ports Authority (GPA) has signed an agreement to
purchase 17 generator sets powered by Tier 4 Interim certified Cat C15 ACERT™
engines as part of an ongoing effort at the Port of Savannah to upgrade older
rubber-tired gantry cranes (RTG) with cleaner technology.
Atlanta-based
Cat dealer Yancey Bros. Co. will adapt the diesel generator sets with
customized enclosures and mounts for installation into 17 RTGs. The project
will start in the first quarter of 2011, with staged upgrades scheduled for
completion within 12 months.
