[QUOTE="Henry Cohen, post: 58782, member: 123"] Re: Wireless Intercom Manufacturers (Vendors)? IIRC Tempest does not have sidetone latency as the sidetone is generated internally in the beltpack. All the current higher end digital intercom offerings have latency due not so much to the A/D and D/A conversions, but rather to the chosen transmission scheme, FHSS TDMA - Frequency Hopping Spread Spectrum Time Domain Multiple Access. Each beltpack is assigned a time slot to receive and to transmit. FHSS further has an inherent latency due to the cycling of the transmitter and waiting for the carrier to come up to full power with each hop. [/QUOTE]
