AETA Audio Systems is expanding its ScoopFone family with a 4G version of the range of professional mobile phones for broadcasters. In addition to HD Voice calls at 7 kHz audio bandwidth, the ScoopFone 4G also allows VoIP calls which allows for the user to transmit through HD Voice, 3G, 4G/LTE as well as wired IP connections within a single box. Coding algorithms available for IP are Opus, G.722 and G.711.
With HD Voice, the ScoopFone 4G uses a dial-up connection over the 3G mobile network providing Quality of Service. HD Voice delivers higher quality voice transmissions by extending the frequency of range of traditional or narrowband voice calls (300 Hz to 3.4 kHz) out to wideband audio ranges (50 Hz to 7 kHz). The 7 kHz wideband sound quality allows the full signature character of the speaker’s voice. Unlike mobile data links, HD Voice delivers a priority connection with secure quality once the call is established — all with lower cost and lower latency, the company says.
In IP the encoding mode is automatically selected depending upon the device being called, with a priority for Opus. A network quality meter guides the user for adjusting the bitrate if needed. The interface is intuitive, making ScoopFone 4G a simple-to-use device with optimal transmission performance. To simplify IP connections, a SIP account is readily available and active.
Like the ScoopFone HD, the ScoopFone 4G works with any microphone and offers mixing between one microphone/line and a second line input, together with a clear interface which journalists can operate with confidence under pressure. The unit is powered by rechargeable NiMH battery with an integrated charger or standard AA batteries.
