Abstract

In this we have talked about the urgent need of introducing more Emergency communication RF frequencies . The reason for needing more frequencies are twofold firstly the frequencies already allocated are much less than needed and secondly all these frequencies needed upgrade the .We have also included frequencies currently used for emergency networks . We have talked about a scenario where the equipment upgrade

br became necessary when the emergency support system was changed to a different frequency . Later in the we have recommended using new digital technologies such as software defined radio , cognitive radio and 802 .11 Adhoc networks for stronger , secure , high data rate and reliable communication

Introduction

As the world is moving ahead the need for radio and wireless communication cannot be denied . This importance becomes more evident in emergency conditions and times .Several frequencies from the electromagnetic spectrum are allocated for emergency time communication by the governments and agencies around the world . One such agency is FCC who is responsible for assigning different frequency bands

There are some specific frequencies that are the designated for the communication in emergency , a table of such allocated frequencies are presented here

000 .5000 International Distress (CW
