TETRA Backhauling via Satellite: Improving Call Setup Times and Saving Bandwidth

TETRA Backhauling via Satellite: Improving Call Setup Times and Saving Bandwidth

In disaster management scenarios with seriously damaged, not existing, or saturated communication infrastructures satellite communications can be an ideal means to provide connectivity with unaffected remote terrestrial trunked radio (TETRA) core networks. However, the propagation delay imposed by the satellite link affects the signalling protocols. This paper discusses the suitability of using...

Improving call bell response times.

AIM To explore and compare call bell response times in two wards in a geriatric evaluation and management facility before and after the introduction of a suite of interventions aimed at decreasing patient falls. METHOD Data on call bell response times were collected over two periods. The first were before implementation of falls prevention initiatives. Data were retrieved from the call bell s...

Dynamic Radio Resource Management for Hybrid Terrestrial-Satellite Backhauling

Jointly power and bandwidth allocation for a heterogeneous satellite network

Due to lack of resources such as transmission power and bandwidth in satellite systems, resource allocation problem is a very important challenge. Nowadays, new heterogeneous network includes one or more satellites besides terrestrial infrastructure, so that it is considered that each satellite has multi-beam to increase capacity. This type of structure is suitable for a new generation of commu...
