Radio Interoperability Needs Governance More Than Technology
Even individually tackling some of the many problems that hinder interoperability today – proprietary technology, insufficient radio spectrum and lack of funding – won’t lead to full communication among first responders until all stakeholders involved begin to collaborate.
Though the level at which the governance structure should originate is open for discussion, what’s not is that the interoperability problem, though it only rears its ugly head occasionally, must be fixed. The National Governors Association tabbed it as its top priority, and it will take painstaking, coordinated efforts among first-responder and local agencies to do it.

Various Types of 2 Way Radios
Radios that can receive and transmit communications are known as 2 way radios. Some common examples are walkie-talkies, CB radios and even cellular phones. While these products are very different in nature, they are common in that they receive and transmit communication and are classified as 2 way radios.
There are many uses for 2 way radios, including a camping trip with the family where walkie talkies help everyone to stay in touch. When in the wilderness, a cell phone is not likely to have a signal and this is why walkie talkies are so helpful. If individuals should get separated from one another while camping, having a way to remain in communication is invaluable. In order for 2 way radios to work, individuals must be on the same frequency or channel to communicate. Before separating, families should make sure that everyone is on the same channel incase the devices are needed.

VOIP – Different Perspectives
VOIP or voice over internet protocol has become the buzzword for the online community, the techno geeks and in these days for the lay man also with subscriptions growing in leaps and bounds since the past two years. In the earlier days of VOIP, the idea was predominantly associated with the voice chat option found in popular messengers provided by yahoo and MSN. The main bottleneck at those times where the slow and sporadic speed of internet which at times fully jeopardized the basic necessity of continuity of a conversation.
Calling to local phones and mobiles were perceived in the earlier days as too much complicated and for most in industry considered it as a superfluous option. The scene changed so rapidly , thanks to the latest developments in technology and up-gradation of infrastructure that has truly revolutionized how we perceive VOIP. The rapid changes in the economies of asian countries like India and China, their opening up of the communication sector to private sector and foreign investment also spearheaded the VOIP trend into uncharted territory surpassing geographical, linguistic and cultural barriers with rates reduced to cents from dollars for international calls. The real potential of the VOIP system lies in its free and unlimited minutes that makes even the most staunch supporter of the traditional technologies vulnerable. Contrary to the traditional modes of communication, there is no prescribed hours for the free call facility and a customer can make calls to selected destinations absolutely free of charge at any point of time and as long as he wants to talk.
