GSM Highway Emergency Telephone (SoS)

Present SOS Telephones

Presently all the Road highways have a mandatory requirement of providing emergency communication telephones points at every 2Km (or near about) across one side/both side of the entire length. This is required as a necessary support in case of any accident or misshappening on the highway. For this, a fiber optic/copper cable is laid alongwith the highway. The communication points are connected to the control room via this cable.

New SOS Telephones

Our system does not require a cable to be laid. Instead it is based on GSM technology. The telephone points are GSM telephone designed to make a call on the pre-stored control room numbers. Now a days GSM network is very strong & available across the highways as well. Each telephone point has a solar panel & the system works on extreme low power, from solar energy.

The system remains in a standby state, drawing negligible power. When a person wants to make a call, he just presses a button. The power switches on & dial tone is heard in the speaker. Within few second, the control room number is automatically dialed. Caller can listen the ring back tone & when the control room answers, the caller can communicate with the control room. In case of unsuccessful call (e.g. control room number busy etc), caller can again press same button to redial.

Advantages

Present Cable System	New GSM System

Initial cost of cabling is much higher.	Initial cost is lower as no cable is required to be laid
Laying Cable takes long time.	No cable laying, This is easier & faster to install
Longer project completion period.	Reduced project completion period.
In case of cable cut, a long section may become unusable & it may take long time to locate the fault & repair.	If a point fails, next point after 2 km is available. So only a small part of road looses the communication.
So a long part of road may loose the communication for a long period.	The locations are fixed & so it is easier & faster to repair.
High initial cost results in higher operating maintenance cost also.	This is more reliable, less break downs.
	Negligible operating cost as GSM charges are very very low.
Besides all these advantages, this GSM system is very easy to operate. Only one button to press for dial/redial/terminate. Also, it encourages the use of solar power.

Application

Ideally suitable for state highways & other roads where budget is limited & costly systems can not be implemented.
Can also be used for national highways to cut down the cost.
Can also be used in programs like emergency child helpline. A phone can be installed in each village with child helpline number pre-programmed. A child can easily press a button of this phone, where as he may not dial the helpline number from conventional phone.
Many similar helpline applications requiring a specific number to be called.
