  1. Tempest Wireless Intercom Overview Wireless Intercom Overview North America v1.3

  2. The Most EvolvedWireless Intercom Available • Unprecedented features • Unprecedented ease-of-use • Unprecedented performance • Unprecedented scalability

  3. The Most Frequency FriendlyWireless Intercom Available • Available as a 2.4GHz or 900MHz system • 2.4GHz legal for use worldwide • 900MHz legal for use in North America only • Identical operation and features in both systems • No frequency coordination required for either system

  4. Understanding Tempest 2.4GHzWireless Intercom • Tempest 2.4GHz is available as a 2-channel or 4-channel wireless intercom system • Tempest broadcasts Digital Data Packets in the unlicensed worldwide 2.4GHz range • Tempest 2.4GHz is not a Wi-Fi system • Tempest 2.4GHz can co-exist with Wi-Fi, and other systems broadcasting in the same frequency band

  5. Wi-Fi Systems and Tempest How Wi-Fi Operates: Wi-Fi uses 3 non-overlapping channels: 1, 6 and 11

  6. Wi-Fi Systems & Tempest - continued • The RF for Wi-Fi is broadcast over a signal that is 22MHz wide • Tempest data is broadcast over a signal that is 1.5MHz wide, giving the Tempest signal a higher effective power • Imagine a flashlight that you focus over a 12” area • Now focus that same flashlight over a 1’ area • You get a much stronger signal with the same power from the flashlight

  7. Wi-Fi Systems & Tempest - continued • This is the Tempest Signal overlaid on top of Wi-Fi RF signals showing the higher effective RF power • 802.11b the more rounded signal • 802.11g the more squared edge signal

  8. Wi-Fi Systems & Tempest - continued • Tempest uses a system called FHSS (Frequency Hopping Spread Spectrum) to change the transmission frequency every 5ms • FHSS makes Tempest almost invisible to Wi-Fi as we constantly change frequencies • This also makes Wi-Fi almost invisible to Tempest as our signal appears much stronger, and the Wi-Fi signal’s power is closer to our noise floor

  9. Wi-Fi Systems & Tempest - continued • Tempest is an all digital system that transmits Data Packets containing the audio and other metadata information for all BeltStations and the BaseStation • Using a system called TDMA (Time Domain Multiple Access) each BeltStation and the BaseStation get their required data • The entire system is on the same frequency at the same time

  10. Wi-Fi Systems & Tempest - continued • Tempest then changes frequency and broadcasts the same data a second time for full Data Redundancy, not traditional diversity • Dual antenna Tempest systems also change antenna every transmission • Then we change frequency again and send the next data packet, and the process repeats • This all happens 200 times per second

  11. Illustrating how this works: • We have two data packets “A” and “B” *not a real data example • Packet “A” contains the sound “Hello” • Packet “B” contains the sound “Good Bye” • How the redundant transmission works:

  12. BeltStations and BaseStation * Dual Antennas On 4-CH Base Only

  13. Packet-1“HELLO” from Antenna A * Dual Antennas On 4-CH Base Only

  14. Packet-1 re-transmits 5 ms later“HELLO” from Antenna B * Dual Antennas On 4-CH Base Only

  15. Audio Packet-2 * Dual Antennas On 4-CH Base Only

  16. Packet-2 re-transmits 5 ms later “Good Bye” from Antenna A * Dual Antennas On 4-CH Base Only

  17. Packet-2 re-transmits 5 ms later “Good Bye” from Antenna B * Dual Antennas On 4-CH Base Only

  18. The Tempest radio has only 3 user settings • The Radio Band • Hopping Pattern (Network Number) • Lockout Key (Security Key) • These are all set in the BaseStation • They can be changed at any time

  19. The Radio Bands • There are seven frequency ranges that cover approved 2.4GHz bands worldwide • They can also be used to avoid a specific Wi-Fi channel if desired

  20. The Network Number: also known as the Hopping Pattern • 43 available Hopping Patterns (0-42) • All patterns use the same 43 frequencies, but at different times • To maintain maximum performance when using multiple bases: • Simply set each base to a different network number • Connect 9-pin Accu-Sync ports from BaseStation to BaseStation • Connect Z-Sync Dongle or Parallel Sync Generator • Tempest automatically handles the rest

  21. Tempest 900MHz Differences Similar RF Operation to 2.4GHz • Tempest FHSS Technology • Tempest TDMA Technology • Single antenna operation • No dual-transmission of data • 37 available Hopping Patterns (0-36) • All hopping patterns use the same 37 frequencies, but at different times • No radio band adjustments available

  22. Tempest 2.4GHz vs. 900MHz*Outside of North America use 2.4GHz only • Propagation of 2.4GHz vs. 900MHz is very different • 2.4GHz can have greater density of users • 900MHz may penetrate certain surfaces better • 2.4GHz can adjust for frequency spectrum • 900MHz can have longer extended antenna cable length • Roaming is 2.4GHz only. MasterBelt is 2.4GHz only. • Both systems have specific RF attributes. It all depends on the application and environment • Remember, when possible, it’s always best to test any RF system for performance on-site

  23. All Tempest Systems • Lockout Key - Also called the Security Key • 256 available Lockout Keys (0-255) • Select any number • This tells the BeltStation it has permission to communicate • Should a BeltStation ever get lost, simply change the Lockout Key # and re-pair the BeltStations. The missing unit will no longer communicate with the system.

  24. All Tempest Systems • After setting the BaseStation parameters simply “Pair” the BeltStation • Connect the 3.5mm cable between the BaseStation and the BeltStation • Turn on the BeltStation and in 2 seconds “Pairing Complete” appears on the display Communication between the BaseStation and the BeltStations:

  25. All Tempest Systems • Tempest BeltStations can “Pair” with up to 64 BaseStations • No more unusable inventory issues due to frequency compatibility, simply pair all BeltStations to all BaseStations and start using all your entire inventory • The Tempest patented radio system makes RF easier than ever before Communication between the BaseStation and the BeltStations:

  26. Because Tempest BaseStations only use one frequency at a time for all users, we can have: • Up to ELEVEN 2.4GHz and FIVE 900MHz systems working in one location with no RF conflicts • Three software configured modes of operation allowing from 80 BeltStations - to hundreds of users with no RF issues, in a single area • Both 2-channel and 4-channel systems work together to suit your application needs

  27. Tempest’s Advanced Features include: • Remote feature control and status monitoring from BaseStations or T-Desk software (Normal Mode only) • Stage announce • GPO relays • Wired-Call functionality

  28. Tempest’s Advanced Features include: • Wireless ISO (Wireless ISO-late) • Aux-in with individual User level control • Remote microphone kill • TDesk PC system management software • Fast, easy and simple firmware upgrades

  29. Unique Tempest FeaturesExclusive Tempest Multi-Mode Operation • Normal Mode • Shared Mode • Split Mode

  30. Normal Mode • Five “Normal Mode” users • 2 or 4 intercom channels • All Belts are dual listen/talk • A or B + C or D • Any Belt may talk at any time • All Belts may talk at once • Talk buttons may be momentary or latching • Full belt telemetry at BaseStation and TDesk

  31. Split Mode • Four “Normal-Mode” users • 2 or 4 intercom channels • A or B + C or D • “5th user slot” unlimited single-channel shared users • Choice of one A, B, C or D • Shared channel is selected at BaseStation • Momentary talk buttons only • Call, SA, ISO, relays are available - they share the same talk path • Common Channel BeltStation settings cannot be remotely adjusted or monitored

  32. Shared Mode • Unlimited users • Belts are dual listen/talk channel A or B + C or D • BeltStations control channels • Only 5 total “talk paths” • Momentary talk buttons only • Call, SA, ISO, relays available but they use a talk path (5) • Shared BeltStation settings cannot be remotely adjusted or monitored

  33. High-Intelligibility and Wide Dynamic Range • Tempest has over 90db of Dynamic Range - far more than any other wireless intercom system • Dynamic Range defines the softest vs. loudest sound you can hear • This allows Tempest to perform very well in extreme noise environments • Others listeners can hear you easily over the background noise • You can hear others speaking without ear-damaging volume levels • This is accomplished without noise-cancelling mics or headsets • Everyone’s communications are heard clearly

  34. Antenna Systems • Tempest is a single point of transmission system • Antennas are mounted on the back of the BaseStation • Optional Remote Transceiver • Up to 1500’ (450m) on standard CAT-5 cable • Either one can be used, but not both at the same time

  35. Remote Transceiver Options • Remote Transceiver: Allows the base antennas to be located up to 1500 feet (450 meters) from the BaseStation without any loss of RF signal • Remote Transceiver Line Extender: Increases maximum allowable distance between a BaseStation and Remote Transceiver • Dedicated RT: (2.4GHz only) Variation of the Remote Transceiver with a dedicated RF transmit connection and a dedicated RF receive connection.
