Mod. ESS-200
Short message sender machines can be particularly useful in emergency situations. In the event of a crisis, such as a natural disaster or a public safety threat, it is often essential to quickly disseminate information to a large number of people in order to keep them safe and informed.

For example, emergency services such as fire departments or police departments may use SMS sender machines to quickly alert residents of an area to evacuate in the event of a wildfire or other natural disaster. Similarly, schools and universities can use these machines to notify students and staff of potential safety threats on campus.

One of the key benefits of short message sender machines in emergency situations is their speed. Unlike other communication methods such as phone calls or emails, text messages can be sent and received almost instantly, making them an ideal way to quickly reach a large number of people.

SMS sender machines can also be used to send out updates and instructions to those affected by an emergency situation. For example, a public safety agency might use these machines to send out information on road closures or evacuation routes, helping to ensure that people can safely navigate through a hazardous situation.

SMS sender machines can be also used to coordinate and communicate with emergency responders. For example, a hospital might use these machines to alert staff of an influx of patients due to a natural disaster or other emergency situation.

A) In Mass SMS Broadcasting mode the unit sends out messages to all cellphones within the system coverage area. 4 or 6 channels need to be set to operate at any combination of GSM, UMTS and LTE carrier frequencies for one selected wireless carrier. The system keeps statistics on successfully delivered text messages. Scheduled messages delivery according to required timer settings is supported. In order to cover maximum number of cellphones, messages broadcasting is done one by one throughout all active wireless carriers

B) Target Specific SMS Delivery: ESS-200 SMS Sender can perform targeted SMS delivery to as many selected wireless phones as the user considers appropriate. It is also possible to upload other target lists collected in the past and check whether the required cellphone is seen in the area.

In certain cases, the SMS Sender can create an unwanted interfering signal for PLMN base stations in the area. To avoid such problems, the unit is equipped with a built-in network monitor displaying all available cellular networks and relevant operating channels (ARFCNs). As soon as the PLMN operator is selected, the user shall run the Network Monitor to detect the weakest ARFCN from the list.
