What is CellAlert?

CEASA formed the Cell@lert project to find technical solutions, and develop technology accordingly if it did not yet exist. CellAlert is the for-profit organisation which implements the actual technology that provides the Cell Broadcast Broker and other infrastructure to make the service actually happen. They follow the 'rules' as set out by the local CEASA association for that sovereign state.

CEASA international helps to write the best practices and MoUs for the deployment, of the proposed Cell Broadcast public warning system, known as Cell@lert. Each nation state has its own CEASA branch, setting the best practices for that soverein state, in conjunction with governmental institues and network operators. The Cellular Emergency Advisory Systems Association (CEASA) is a citizens action initiative, a not for profit group. Originally formed in the US, the international branch creates a harmonised international channel coding scheme which enables international and cross border use of CB, in a multi ligual environment. It also co-ordinates the allocation of channles for international purposes such as maritme. There are other active moves in US, Canada, Australia, Switzerland and Germany. A very successful group is active in Holland. It consists of those parties who would wish to see mobile devices used for the purpose of public warning, and those who will be part of the technology chain who will make it possible. All parties are welcome to join Networks such as mobile phone companies will be vital to provide the infrastructure over which the messages will flow to citizens at risk. They will seek assurance that only genuine bona fide sources will have access to their customers and those security systems will prevent unauthorized access such as spamming. Cell@lert will provide the operating company who will administer the Cell Broadcast Broker, which will authenticate users and provide the user friendly map and GUI which officers use to input messages. . Cellcast Corporation will purchase access to the networks and the licensing of all related technology. User groups such as governmental agencies and citizens groups will want to make sure that any messages are pertinent proportional and authorized. Accordingly there will be a system of Trust Protocols setting out the Memoranda of Understanding between them.	What is CellAlert?

What is Cell Broadcasting? 1) Cell Broadcasting (CB) is an existing function of most modern digital mobile phone systems, such as GSM UMTS and CDMA. It differs from SMS in that, while it does put text messages on the screen of the phone, (like SMS does), it does this to 'all-at-once 'and not one-at-a-time as SMS does. 2) This is particularly valuable in times of emergency as government may need to reach millions of citizens within seconds; all while telecom systems are in full overload! 3) CB works even in full overload, does not itself contribute to load, will not crash the networks, and can reach 95% of mobile phone users within about 20-30 seconds. 4) CB is scalable from about one block to the whole country, without causing significant overload problems of its own. Officials can select towers or groups of towersto make the mesage geo-specific. 5) It is possible to secure the whole communications link from authorised sender to citizen, so that citizens can trust the message, and networks can be sure that it wont be abused for spam or hacks. Since it uses existing mobile networks infrastructure, it is suitable for developed and least developed countries alike, Significantly, we have developed technology whereby the senders can select the area where the message is to be sent, giving the ability to give different messages to different areas. In addition, since there are 64000 different channels, different uses can be kept apart so that people are not bothered by spam. This means that many other uses can be found for this feature, some of which may be used by mobile devices but some of which may be for other devices., such as in car navigation and information services. The Cellcast Corporation will make the necessary arrangements so that users do not conflict with each other, and there is no negative impact on the networks.	Contacts Hon.
