A COMPLETE SOLUTION TO THATLOT OF NON RENEWABLE ENRGY

WHICH IS CONSUMED IN RUNNING

A MOBILE PHONE

A MOBILE SYSTEM COMPLETELY

BASED ON SOLAR ENERGY



When we talk of a mobile system, then only

mobile phone or a mobile network can not be

mentioned but both of these together form a

complete mobile system.Mobile system

Mobile

phone

Mobile

network

so here is a complete mobile system which

works on solar energy.



A solar based mobile phone works normally asother mobile phone while it charges up via a solar

panel on the back of the phone in both sunny as

well as cloudy days, apparently generating

enough electric power to make a call anytime.



These phone provide a unique user

interface ³to draw attention to preserving

our fragile environment´.

These phones will be particularly useful in rural areas

where there is no mains electricity.

The phone can get fully charged in 8-15hours depending on the climatic

conditions. An hour of charging can yield

between 5-15 minutes of talk time

depending on the climatic conditions.



This mobile network has been designed from the ground

up- the hardware, software, towers and network

architecture-to extend existing GSM networks into areas

they could never before serve.

Its software

Its deployments

Its architecture

Its technology



To drive down power, cost and size we had to design our own hardware. The

result ² three boxes at the core:

BlueBox BTS ² The low-power, low-cost BTS (Base Transceiver Station) in a

box. Complete GSM Base Station functionality in a single box, including

microwave backhaul. It comes in two capacities ± 1 TRX and 2 TRX.

GreenBox BSC ² the world¶s first rural-optimized

BSC (Base Station Controller). One GreenBox� BSC supports up to 16 BTS

nodes (WorldGSM� Rural, Road or Village sites).

OrangeBox MSC ² the compact MSC (Mobile Switching Center) for rural

deployments. One OrangeBox� supports up to 6 GreenBox� BSC nodes,serving over 10,000 subscribers.



The core network is built on the MontaVista distribution of Linux. This

confers the following advantages:

Extreme stability ² carrier-class uptimes

Flexibility ² choose from a wide variety of silicon and hardware

Ubiquity ² easy to find skills and resources

Open Source ² free and easily adapted

Wide acceptance ² by operators all over the world



It is deployed in any of three site configurations to

support two different types

of deployment.

TheThe RuralRural DeploymentDeployment ²gives low cost coverage of

entire rural areas by

combining free-

standing Rural Site Base

Stations with rooftop-mounted village sites.

TheThe RoadRoad DeploymentDeployment ² gives fast, low-cost coverage

along major roads and arteries, using the road

site Base Station.



It is based on VNL¶s Cascading Star Architecture�, a unique approach

to Radio Network Planning, with several important advantages:It allows WorldGSM� to use panel or omni antennas to provide

coverage.

It provides an easy entry into previously uncovered areas.

It enables low-cost expansion as uptake increases.

All three contribute significantly to the cost, power savings and

sustainability of the WorldGSM� system.



Solar based network is fully GSM compliant, so it easily links to existing

networks, dramatically extending their reach. But it¶s different from traditional

GSM in these important ways:

LowLow--power power ² at less than 100W per Base Station, the entire system can be run on

solar power. No power grid or generator necessary.

Low costLow cost ² a fraction of the cost of traditional GSM Base Stations; profitable at

very low densities and ARPUs.

Self Self--deployingdeploying ² an entire Network Base Station packs into two carts and is

easily installed by unskilled field staff who may not be able to read or write. Nobuildings, power, air conditioning. Just point it South and turn it on.

Near-Zero Maintenance ² update software remotely and perform simple swap

repairs if needed.

Cascading Star ArchitectureCascading Star Architecture ² a unique, modular architecture optimised for low-cost rural expansion; with local switching to minimise backhaul.
