Formed in 2011, MULTIVOICE has been developing and perfecting mobile, hands-free wireless systems that enable simultaneous and secure group communications among fearless individuals in rigorous environments. The MV-AUDIBLE Wireless Mesh Network Intercom™ — MULTIVOICE's first product — was announced in March of 2015; it allows teams of up to eight co-workers to talk simultaneously on a secure, hands-free wireless network at distances of up to one mile apart without using a base station. Additionally, the MV-AUDIBLE allows an unlimited number of Listeners on the same wireless network, while also allowing Listeners to become speakers as previous speakers drop into "Listen-Only" mode.MULTIVOICE's technologies revolve around the Industrial, Scientific and Medical (ISM) wireless communications frequencies of 902—928MHz in a mixture of patented, patent-pending and trade secret inventions, including U.S. Patents 8,681,663 and 8,705,377. By utilizing FDMA (Frequency Division Multiple Access), TDMA (Time Division Multiple Access), Frequency-Hopping Spread Spectrum and select proprietary wireless communications methodologies, MULTIVOICE enables real-time, simultaneous, secure and hands-free wireless audio communications among group members.MULTIVOICE's MV-NEXUS is built to fit in standard 5.11-size pockets and pouches common in military, public safety and industrial clothing and gear. A Wireless Mesh-Network Intercom device which measures 5.3x3.3x1.3-inches, weighs 10.9 ounces, uses two rechargeable 3000mAh Lithium-ion batteries, and ships standard with a 3.5-inch-high antenna, the MV-NEXUS delivers up to 17 hours of actual talk time without recharging. MULTIVOICE has also announced the MV-COMBINER, a new accessory that allows team members to simultaneously and securely share MV-NEXUS communications with a network of Push-to-Talk (PTT) & P25 radio users, thus augmenting and enhancing the functionality of PTT & P25 radio networks.
