We propose a mechanism to deploy UAVs as aerial base stations to provide network connectivity, QoS support, and reliable communication in a flash crowd and emergency situations.
Wireless communication networks provide a critical infrastructure, particularly in emergency situations due to disruptive events such as natural disasters or terrorist attacks. However,
Natural disasters can severely disrupt conventional communication systems, hampering relief efforts. High-altitude tethered balloon base stations (HATBBSs) are a promising solution to communication
Existing telecommunications networks may be compromised by the disaster, or saturated by demand. Maps showing existing and planned coverage of telecommunications infrastructure may be an
Hier sollte eine Beschreibung angezeigt werden, diese Seite lässt dies jedoch nicht zu.
In this paper, a holistic and rapidly deployable mobile network is presented. This is composed of a LAP-based airborne communications segment combined with a satcom-enabled Portable Land Rapid
For emergency communications in an internet of thing (IoT) network, a large number of gateways are distributed to gather the data traffic. Considering the practical difficulty of deploying
Natural disasters can severely disrupt conventional communication systems, hampering relief efforts. High-altitude tethered balloon base stations
An emergency communication system is necessary for first responders, who need to enter areas with no network coverage or damaged network infrastructure due to natural or man-made disasters to
However, a single HATBBS is insufficient for large disaster zones, and limited resources may restrict the number and energy capacity of available base stations. To address these
Since 2005, the ETC has responded to over 40 humanitarian crises around the world. Within 48 hours of a disaster, the ETC provides vital security
The Emergency Telecommunications Cluster (ETC) is a global network of organizations that work together to provide timely and effective inter-agency communications services in humanitarian
The 370M PDT digital cluster system includes a PDT + LTE broadband-narrowband fusion core network, a fixed base station, a mobile base station, an integrated command and
With the development of 5G technology, a convenient and fast emergency communication solution is needed when the local ground base station is unavailable for disaster.
Great options await in 2025''s top ham radio base stations for emergency comms—discover which model best fits your needs today.
We propose a broadband-narrowband integrated emergency communication network to provide an effective solution for visual dispatch of emergency rescue services.
In disaster situations, it will be crucial to set up temporary UAV-based emergency flying base stations (BSs), provide wireless coverage in cellular networks, and establish communication
Considering this fact, this paper studies the non-orthogonal multiple access (NOMA) and multiple unmanned aerial vehicles (UAVs) assisted emergency communication system, in which
The base station collects all the data and also informs the other emergency department. It provides the location of the disaster area by sending the coordinates X and Y (cod x,y) toward the
The collaborative deployment of multiple UAVs is a crucial issue in UAV-supported disaster emergency communication networks, as utilizing these UAVs as air base stations can
In disaster relief operations, both emergency communication and personnel positioning are critical. This paper proposes an enhanced unscented Kalman filter (UKF) positioning algorithm for communication
Therefore, an emergency communications strategy based on Device-to-device (D2D) multicast is proposed to make PSN more flexible and rapid. Nearby users can communicate directly
The 29 partners of the World Food Programme (WFP)-led Emergency Telecommunications Cluster (ETC) are on hand within 48 hours to work with
Explore best ham radio base station setups for emergency communication networks with reliable, long-range performance for critical situations.
The experimental results provide a sufficient data rate to make an independent mobile base station to restore communication infrastructure in areas that experienced environmental
