Introduction
What makes Tempest so different?
CoachComm has been building wired systems for over 16-years and wireless systems for over 11-years to supply quality
communications to D-1A teams nationwide. Therefore, CoachComm’s knowledge of wireless technology in the D1A football
arena is vast and our experience is deep. When it came time to build the next generation of equipment to service that industry
– CoachComm was up to the challenge.
Tempest is so unique that it has taken not only the football world, but other wireless intercom applications by storm! Simply put,
Tempest is the world’s first fully featured, 2.4 GHz, frequency hoping spread spectrum wireless intercom. Tempest now comes
in a 900 MHz model offering the same features.
Fully Featured
Tempest is the first wireless intercom system to employ the feature set that end users demand. Some of the unique features
include:
» Durable industrial design
» No FCC license required
» No frequency coordination required
» Easy user set-up and operation
» Multiple battery options
» Call with vibrate
» Remote Mic Kill
» Unlimited number of BeltPacks
» Remote transceiver
» And much more..
These features come together to form an incredible product called Tempest. Tempest wireless is the heart of the Tempest NG
sideline communications system. Tempest wireless together with enhanced tools for the wired portion of the system make for
an incredibly robust, easy to operate system.
2.4 GHz
Previous NG and UC systems have operated in the FCC part-74 band. Over the past few years, the FCC has been relocating TV
stations from the old analog domain to the new digital era. As a part of this process, many of the frequencies used by the NG
and UC systems have either become over crowded or are no longer a legal option.
CoachComm designed the new Tempest wireless product to operate in the 2.4 GHz frequency band. This band is open for general
use and does not require special licensing by the end-user. In addition, this band is specifically set-aside by the FCC for devices
such as Tempest that work well together even in a crowded RF spectrum. The idea is that devices constructed to work in this band
are supposed to work well even if there are other devices in this same frequency band.
900 MHz
In addition to the 2.4 GHz model, the Tempest family of products now includes a 900 MHz model, Tempest NG900. The 900 MHz
model is a technologically-enhancing accessory to existing 2.4 GHz systems, giving users more options on game day. The user
inferface is exactly the same as the 2.4 GHz model, therefore no new training is required. This band is also a license-free band.
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
Tempest 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. The particular methods used in the Tempest FHSS protocol
are covered by seven (7) U. S. patents and represent the state of the art in FHSS technology.
