ERC Communications Summary
LOGAN STOREHOUSE ERC EMERGENCY COMMUNICATIONS SUMMARY
(NOTE: This has been condensed from a Welfare Services white paper, circa 2008 by Brother Douglas L.
Reneer of LDS Church Welfare Services)
COMMUNICATIONS TECHNOLOGY WIRED OR LAND-BASED TELEPHONES
We are most comfortable with these telephones because we
use them automatically without giving conscious thought to their operation; We
know their advantages, but some of their weaknesses need some explanation.
1.Overload; The telephone system is designed and built to handle a specified
number of calls at any given time, usually between 10 and 15% of its
subscribers. If more users attempt to call they will not get a dial tone. In a
disaster most of the subscribers will attempt to place a call to friends or
relatives or to local authorities, causing an overload.
2. Physical damage. The modern telephone system has a very sophisticated infrastructure. It is only
necessary to have a failure at one point in the system path to cause the system
to fail.
3. Dependence on commercial power. At one time the land-based telephone
network was extremely reliable. It consisted of a relatively simple network of
copper wires that carried their own power. The phone companies provided power
for the network and emergency power as well. Present day systems no longer use
copper wired trunk lines but fiber-optic lines which are more fragile and
require a device know as a digital-loop carrier that is powered by local power
companies. Therefore in most cases when the local power goes the phones go. In
addition many homes have replaced their corded phones with cordless phones that
are household power-dependent.
CELLULAR TELEPHONES Most of us use cellular
phones on a regular basis and are quite comfortable with their use.
1. Overload. The cellular system is even more sensitive to overload than the wired system.
The cellular industry is extremely competitive. Economics dictates that system
capacity to be sized very closely to the maximum number of calls placed on a
normal day. Overload may occur even during normal times when usage tends to be
the greatest.
2. Physical damage. The cellular system is even more susceptible
to physical damage than the land-based system since it is entirely dependent on
the land-based system to interconnect its cell sites plus it includes cell
towers that add to the vulnerability.
3. Dependence on commercial power.
Initially each cell site was constructed with battery backup that could maintain
operation for up to 4 hours. Current practice is to build sites with no back-up
power. When commercial power fails the cell site is down.
4. Portable cells. Portable cells called cells on wheels (COW) exist in the inventories of some of
the larger providers. They are dispersed around the county with no more than one
in each service area. They are self-contained with their own power generation.
Because of their very limited numbers and the distance most must be transported
they are not available in the initial hours of the disaster. A COW only works
with is own cellular provider. Economics curtails the production of more than a
few of these portable cells. Cost of a COW is around $300,000.
5. Cell phone systems are not mutually compatible. Cell phone providers use different
technologies which include TDMA, GSM, CDMA and wideband CDMA. AT&T and Cingular
use TDMA. Verizon, Sprint and Cricket use CDMA. A few of the providers including
AT&T are providing GSM service which is used internationally. The lack of a
standard cell phone protocol plus provider unique software makes it impossible
to use a portable cell for more that a single provider.
6. Some cell phone providers will bring in large quantities of cell phones to a disaster location
and distribute them to governmental agencies and the Red Cross as a public
service. The effect is sometimes negative because the additional load on the
system adds to the difficulty of getting a circuit.
AMATEUR RADIO Advantages:
1.Reliability. Amateur radio is by far the most reliable emergency communications
mode due to its simplicity, independence from commercial infrastructure,
flexibility and redundancy. Public service agencies use ham radio to interface
between their individual communications systems and to provide additional
communications resources at locations such as shelters and relief agencies.
2. In addition to providing point-to-point communications like the telephone it has
a conferencing capability that allows communication with large numbers of
locations simultaneously as well as monitoring information sources.
3. Costs are minimal (new hand-held radios sell for as little as $30) and the cost to the
Church could be considered close to nothing since most operators already own
their own equipment.
4. Because amateur radio includes an immense number of
frequencies, many of which can be used to communicate worldwide, the FCC
controls its use by licensing its operators. Licensing requires some study to
pass the examination, however in recent years the FCC has made it much easier to
obtain a license, especially for the technician class for local communications.
In the US an unlicensed person may operate a ham radio if a license holder is
present to assure that FCC regulations are being complied with. Thus a Church
leader may use the radio if he desires or he may have his operator communicate
in his behalf.
5. Amateur radio allows direct interface of Church officials with
civil authorities and other relief agencies.
6. In severe disasters amateur radio is generally the only available mode of communication in the early hours
of the disaster aftermath when communications is most critical.
7. There are many new technologies available in amateur radio to add diversity and
capability.
Disadvantages:
1. In a severe disaster radio operators in the
affected area may be so impacted as to not be able to serve. Personal and family
needs will naturally come first. To counter this situation planning by Church
leaders may include provisions for communication functions to be handled by
operators from a neighboring stake or ward.
2. Licensing may be considered a
disadvantage in that it requires a degree of effort. The plus side of licensing
is that the trained operator brings communications skills that may be very
useful in disaster situations.
3. Communications are not secure. Anyone with the
proper radio equipment may listen.
SATELLITE PHONES:
Advantages:
1. MostBishop’s Storehouses have at least one satellite phone. The Church is using the
Iridium system, the same satellite provider used by the Department of Defense.
The advantage of this is the assurance that Iridium will be maintained as a
reliable system and is likely to remain in business for the foreseeable future.
The capacity of the Iridium system exceeds any potential demand so that there is
almost no chance of overload except in specific situations such as occurred in
Iraq during the recent war.
2. The system is independent of local infrastructure.
3. The satellite phone offers privacy of communications as does
the cell or wired phone.
Disadvantages:
1. The principal problem experienced with the satellite phones is the lack of familiarity with its operation. Like
any electronic device it requires some training to be used comfortably. People
who use it regularly have no difficulty with it.
2. The hand-held model generally must be used outside to obtain a reliable satellite connection. This
may be difficult to impossible in certain situations.
3. Battery maintenance may be a problem if the phone is not used regularly and the operator is not familiar
with correct battery charging procedures. It is current Welfare Service policy
to use a layered approach to emergency communications. Reliability is
greatly enhanced by the redundancy of having multiple technologies available to
back up the telephone. Amateur radio and satellite telephones complement
each other very nicely in the backup role.
RECOMMENDED MODES OF COMMUNICATIONS IN THE EARLY HOURS/DAYS AFTER A DISASTER
--GENERAL PRINCIPLES: Use the simplest and most familiar mode possible. If telephones work—use them.
1. Ward to ward or stake:
Amateur radio. Where distances are short CB,FRS/GMRS/MURS radios may
work.
2. Stake to on-site Church emergency operations center (EOC): Amateur
radio.
3. Stake or on-site Church EOC to local government EOC and relief
agencies (Red Cross, etc.): Amateur radio.
4. Stake or on-site Church EOC to nearest bishops’ storehouse: Amateur radio.
5. Between bishops’ storehouses: Satellite telephone or amateur radio.
6. On-site Church EOC or bishops’ storehouse to Church headquarters:
Satellite phone or amateur radio.
TIPS ON USING THE LAND-BASED TELEPHONE DURING OVERLOAD CONDITIONS
1. If you pick up the phone and there is no dial tone, rather than hang up and try again later, keep
the handset to your ear and wait for a dial tone. When overloaded, the phone
system operates on a queue basis. The first one to pick up is first in line. So
waiting will eventually bring you a dial tone.
2. Pay phones have priority over residential and business phones. You have a much better chance of getting a call
through by going to a pay telephone. You may have noticed in the TV coverage of
the recent blackout in the eastern part of the country, scenes of long lines at
pay phones in New York City. Due to the overload these were the only operating
telephones in town.
3. The two suggestions above do not apply to cell phones.
Getting a call through on an overloaded cellular system may be aggravated by the
fact that in some areas law enforcement, medical and fire services are issued a
code that gives their calls priority over all others. Some states do not allow
this priority system for fear of incurring lawsuits.
Mercury Amateur Radio Association (MARA) Church leaders should be aware that
although MARA once served as the emergency communications organization for the
Church, that relationship was terminated in 1991 for legal reasons. The Church
and MARA no longer have any relationship. Emergency communication for the Church
is directed by Welfare Services under the name of Emergency Response
Communications (ERC). MARA continues to exist as a club, but should not be
relied upon to serve in times of emergency. The Church emergency communications
program is outlined on page 15 of “Church Welfare Resources, for use in the
United States and Canada”.
