Mission-critical communications used worldwide for public safety have been based on narrow band solutions, framed in the different protocols included in Land Mobile Radio (LMR), such as APCO 25, used by the National Police. Although these technologies have been of great importance and have a fairly consolidated implementation maturity for reliable voice transmission, they have limitations for the transmission of data such as images and videos, making it necessary to take advantage of technology such as Long Term Evolution (LTE). In view of this need, it was carried out a technical scientific literature review, verifying the state of the art in several databases; likewise inclusion and exclusion criteria were determined for the study, thanks to which it was possible to identify that today there is no technological capacity to develope a LTE network for public safety; based on the above the need for a technological implementation that guarantees the coexistence of the two LMR and LTE neworks was identified , taking advantage of the benefits of each one of them in a sum that increases the technological capabilities in the police service.
