The "basic" nature of the product indicates the removal of the standard RS-232 and RS-485/422 ports. In addition, the TWE-Basic is a "slave-only" device, so it must be used in conjunction with a standard TWE or TWE-BUS radio acting as the master. Like the other Trusted Wireless radios, the basic version features the MOTR-9 ™ radio platform, a 1-watt, frequency-hopping spread spectrum (FHSS) transceiver. It operates in the license-free 902-928 MHz ISM band. The MOTR-9 radio lets the user... (read more)Browse Wireless Modems Datasheets for PHOENIX CONTACT USA

Smart Computing Article - frequency hopping spread spectrum (FHSS) to FTP
developed by the military in which the transceiver spreads the signal's power over a wide range of frequencies. There are two types of spread spectrum systems: DHSS (direct sequence spread spectrum) and FHSS (frequency hopping spread spectrum). With FHSS, the data signal is changed into a radio

How Does Direct Sequence Spread Spectrum (DSSS) Differ from Frequency Hopping Spread Spectrum (FHSS)?
operating under FCC spread spectrum ISM band regulations tolerate interference from neighboring radios and interference from sources other than radios, making them less prone to signal loss. Here's why: The radio spectrum is divided into frequency bands, with each band divided into frequency channels

Spread Spectrum
Spread spectrum is a technique that is used to reduce the impact of localized frequency interferences. To achieve this, it uses more bandwidth than the system needs. There are two main spread spectrum modalities: direct sequence and frequency hopping. The principle of direct sequence spreads
