This FHSS system combines the power of digital technology with narrow band FM modulation technique. Merging the two technologies facilitates a radio communications system that maintains a narrow band base signal to ensure for maximum usable range within a given dB power budget, comparable to traditional fixed frequency narrow band FM radios, but with the added benefit of wide band digital security and privacy provided by the frequency hopping spread spectrum algorithm. Maintaining the information signal as narrow band FM modulation centered on discrete frequencies allows for a large pool of non-overlapping hopping frequencies to draw upon within a given section of the radio frequency (RF) spectrum. The pseudo-random drawing of the hopping frequencies spreads the total signal power equally over the entire bandwidth of the RF spectrum used, which ensures minimal interference between many simultaneous, independent users. Interference Free is a major advantage that eXRS has over existing FRS and GMRS radios. Based on a contracted study from the Electrical and Computer Engineering Department of a major university, more than 100,000 eXRS users within talk range can enjoy uninterrupted communications. Whereas, FRS/GMRS quickly becomes unusable with just a few tens of users within range of each other. Bottom-line is that the eXRS two-way radios provide private communications in areas where FRS/GMRS conversations can be congested or impossible. Depending on which model you choose, your eXRS radio will have 1,000, 10,000, or all 10 Billion eXRS channels available for your use. Each radio offers Voice-operated transmission (VOX) for hands-free operation with headset compatibility. | | | Features: | |

TriSquare TSX-100 eXRS reviewApr 30, 2008
By Johnnie Martinez
In comparison tests, the Tri-Square radios have generally held up favorably. The audio is a bit fuzzy compared to the Motorola radios and the overall range seems to be a bit longer than the Motorolas, except when the Tri-Square radios dip below the horizon. The 900 MHz frequency range is, as one would expect, somewhat more linear and subject to line-of-sight limitations than the 460 MHz FRS radios. The analog FRS radios will maintain a stronger signal connection under less optimal line-of-sight conditions than will the Tri-Square units. A better antenna and/or a bit more power might ensure the accuracy of Tri-Square's claim that its eXRS radios will exceed the range of FRS radios under comparable conditions.
