What is an "Active State of Emergency" ?
An "Active State of Emergency" is a situation in which an authorized security authority declares that localities in a certain area are in state of active emergency preparedness and defense.
Upon declaring this situation, the local authority engages in actual operation of its entire emergency systems, including opening shelters and staffing emergency systems as determined in the preparation and exercise for these situations in advance.

Reasons for the collapse of communication networks - Cellular:
Cellular communications can stop providing service not necessarily
because of a malfunction or damage – but because of a collapse
Localized due to the overload of users that cellular's cells in a
certain area cannot deal the load of such of multiple callers at the
same time.
For example:
An area in a settlement where a certain incident occurred, such as a rocket or bomb's hit. Rescue forces are coming, as well as local authority's representatives - but also many curious nearby residents who immediately broadcast over the net or calls by using their mobile phone - Reports and information for friends and they relatives, such of reports that include media contents (photos and videos), when on the other hand, relatives and friends calls to check if their loved ones are safe.
The result
The situation in which hundreds and thousands of residents and other users activate at the same time one or more cellular cells within a define given area - immediately causes a failure in the provision of service to all cell phone operators there.
Officials on behalf of the local authority, who went out to fulfill their duties in the affected area – will find Therefore, that they are disconnect themselves from the emergency's operating centers, the Authority's operations room and other officials – as long as they will try to contact them via their cell phone.

Failure due to a technical problem:
Technical problems that can affect the provision of localized or
regional cellular service are mainly because of the following events:
-
Physical damage to the cellular cell tower
-
Disconnecting of the physical/wireless line of communication
between the cellular tower control room and its regional Control.
-
System's power supply Interruption (Electric line, generator that
stopped working, backup batteries that failed to backup, etc.).
-
This is another reason why the local authority's representatives and other officials must leave to the off-road with wireless radio-communication personal device - and not trust on they personal mobile phone to control on the event.


Telephony and data network failure (Internet):
Landline telephone and data networks rely on 3 main components
that are vulnerable most in an emergency
situation:
-
Continuous and ongoing electricity supply to all of the devices
-
involved
-
Maintaining the integrity of a physical line between the local
-
telephone / data hub users
-
Proper regional telephone exchange including its subsystems at the defined area
A malfunction in any of the situations described above will immediately disable
telephony and data network at the emergency operating centers.
