Embodiment Construction

[0011] The present disclosure relates to allowing radio frequency ("RF") signals from base stations to be demodulated and transmitted over a data network. The demodulated signal can be modulated onto an RF carrier and transmitted to the mobile station through a distributed antenna system and / or repeater.

[0012] exist figure 1 TETRA base station 102 is communicatively coupled to a base station TETRA-to-IP converter ("BS-T2IP") 104 . In the downlink direction, BS-T2IP 104 may demodulate signals received from base station 102 using Terrestrial Trunked Radio (TETRA) modulator / demodulator 106 included in BS-T2IP 104 . Demodulated data from signals received from base station 102 may be encapsulated into TCP / IP data packets and transmitted by Layer 1 (L1) / Layer 2 (L2) / Layer 3 (L3) interface 110 via wired data network 108 To Mobile Station TETRA to IP Converter (“MS-T2IP”) converter 112 . Here, demodulated TETRA data may be extracted from TCP / IP data packets by L1 / L2 / L3 interface...

Abstract

One embodiment is directed to a system comprising a first converter unit configured to receive a first modulated enterprise signal from an enterprise base station, demodulate the first modulated enterprise signal, extract enterprise data from the demodulated enterprise signal, and transmit the enterprise data to a modem over a wideband wireless communication network. The system further comprises a second converter unit configured to receive the enterprise data from the modem. The modem is configured receive the enterprise data from the wideband wireless communication network. The system is configured to create a second modulated enterprise signal corresponding to the first modulated enterprise signal using the enterprise data and wirelessly transmit the second modulated enterprise signal to an enterprise mobile station.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application No. 62 / 153,114, filed April 27, 2015, which is hereby incorporated by reference. Background technique [0003] Certain aspects and features of the present disclosure relate to transmitting low bit rate signals over long distances using broadband networks. [0004] Base stations and mobile stations typically communicate directly with each other (eg, using radio frequency (RF) signals from antenna to antenna). However, sometimes a mobile station may not be able to communicate directly with a base station that is too far away, or because there are obstacles between the base station and the mobile station. For example, there are fewer public safety systems than commercial systems. Thus, in such cases, a repeater (eg, a distributed antenna system ("DAS")) may be used to carry signals from the base station to the mobile station. Base stations can commu...
