Introduction
What makes X-System so different?
CoachComm has been building and providing wired and wireless systems for over 25 years to supply quality
communications and practice equipment to every level of football nationwide. Championship-winning teams have found
confidence in our Tempest FX system, Connex system, and most recently our X-System. Our latest solution combines the
mobility and functions you’re familiar with from Tempest FX and pairs it with our latest development in design and agility
from the X-System.
X-System makes use of the newest available communications technology and meets our customers’ demands for more
users, better audio, and future-based features.
X-System is the first wireless communications system to innovate the following unique features:
• Better Frequency-Hopping Spread Spectrum performance in dome venues
• Enhanced 900MHz wireless performance
• Better 7k audio quality
• High Density mode provides ability to add as many coaches as you need
• X-Ware software user interface for monitoring and customizing the X-System
These features come together to form a powerful product called X-System. X-System, together with enhanced tools for the
wired portion of the system, makes for an incredibly robust, easy-to-operate system.
Frequency Considerations
900MHz
CoachComm designed the new X-System to operate seamlessly in the 900MHz frequency band. This allows multiple
devices to operate within the band with minimal interference or reduction of range and performance.
The 900MHz ISM frequency band is a portion of the RF spectrum available for unlicensed use in North America and other
various locations with no frequency coordination. In North America the 900MHz band is 902–928 MHz. X-System utilizes up
to 26 MHz of this spectrum.
Frequency-Hopping Spread Spectrum
Frequency-Hopping Spread Spectrum (FHSS) is a means of RF transmission. In FHSS, the signal hops to various
frequencies—hence the name. In doing so, it spreads the data (voice in our case) across a wide area of the RF spectrum.
Devices such as those in X-System collide constantly with other devices in that frequency spectrum and must have
mechanisms built into their protocol to allow for data redundancy to provide acceptable user performance.
