Cellular broadband Internet of Things (IoT) applications are expected to keep growing year-by-year, generating demands from high throughput services. Since some these deployed over licensed mobile networks, as long term evolution (LTE), one already common problem is faced: the scarcity spectrum cope with increasing demand for data rate. The LTE-Unlicensed (LTE-U) forum, aiming tackle this problem, proposed LTE-U operate in 5 GHz unlicensed spectrum. However, Wi-Fi consolidated technology...
There is substantial literature covering both problems and solutions related to the operation of Long Term Evolution (LTE) networks in unlicensed spectrum (LTE-U) while coexistence with other technologies, such as Wi-Fi. However, a seldom explored scenario between multiple LTE-U networks. Within this scenario, big issue establishing optimal configurations that take into account fairness among different operators coexisting same coverage area. Solutions problem could, for instance, react...
Recent studies and literature reviews have shown promising results for 3GPP system solutions in unlicensed bands when coexisting with Wi-Fi, either by using the duty cycle (DC) approach or licensed-assisted access (LAA). However, it is widely known that general performance these coexistence scenarios dependent on traffic how adjusted. Most DC configure their parameters statically, which can result losses scenario experiences changes offered data. In our previous works, we demonstrated...
As the frequency spectrum becomes more and occupied, discussions about technologies sharing same band grow stronger. However, there are bands reserved for use of industrial, scientific, medical applications, so called ISM bands. For using this range, it is required to adopt some coexistence technique.With intention providing higher speeds users while keeping them connected network, LTE in unlicensed (LTE-U) devised. This work analyses two techniques proposed as LTE-U: LTE-LBT...
