GLENSOUND BROADCASTERS MOBILE PHONES - 3G

Glensound HD Voice Broadcasters' Mobile Phones make it possible to use the 3G UMTS network as an audio link, with a bandwidth of up to 7kHz, for broadcast applications. The increased bandwidth is more suitable for live reporting applications as well as higher-quality IFB and talk back applications. Should a 3G network not be available, they will also act as a normal quad-band 2G GSM phone. They have balanced, line-level connections, with XLR connectors, for ease of interfacing to broadcast mixers, recorders, or computers. The portable version also has a dynamic microphone input. The phones connect as a voice call, so will have the same quality of service as a normal mobile phone call. The call quality will remain constant over the duration of the call regardless of the number of other mobile phones being used in the area. As a result, they are particularly suitable for reporting in highly-congested mobile phone areas such as football matches or concert venues.

The phones connect to 3G mobile phone services, as well as 2G. When connected to a 3G service offering 'HD voice', they provide a bandwidth of approximately 7kHz; a substantial increase in audio quality compared to a 2G or PSTN phone. However, in order to take advantage of the increased bandwidth, the call must be received by another 3G phone using 'HD voice'. Glensound 3G phones can be used to connect to PSTN or 2G phones, but in these cases the bandwidth increase is lost.

Glensound also offer 2G mobile phones. These connect to a mobile network and offer an audio bandwidth of approximately 3kHz. They can make a call to a another mobile phone or a PSTN phone number. With PSTN, the audio contribution can be accepted by an existing telephone hybrid, coupler or a phone-in system. Alternatively a Glensound portable or rack-mounting mobile phone can be used to receive the call, either at fixed premises, or on location, say in a outside broadcast vehicle. The 2G models are suitable for areas where 3G 'HD voice' services are simply not available, or it is not possible to have a 3G 'HD voice' phone at both ends of the connection, or simply that the enhanced audio quality is not required, perhaps for a cue feed.

In 3G UMTS mode, the standard version offers 900MHz, 1900MHz, and 2100MHz bands. An optional 3G UMTS version is available for compatibility in other parts of the world offering 850MHz, 1900MHz, and 2100MHz. In 2G GSM mode, they connect to any quad-band network at 850MHz, 900MHz, 1800MHz, and 1900MHZ for international compatibility. Audio bandwidth is 50Hz to 7kHz in 3G mode or 300Hz to 3.4kHz in 2G. Audio circuits are shielded from radio frequency interference, so the self generated RF will not interfere with the audio.

A large LED flashes and a sounder, which can be switched off, rings to indicate incoming calls; there is a variable auto answer. A nine-memory phone-book offers access to stored numbers and a redial button can be used to call the last-called number. A 6.35mm A/B gauge headphone socket is available for monitoring. The balanced, analogue, (XLR) audio inputs and outputs have separate controls for level adjustment. The aerial is connected by a standard SMA socket; different aerials may be connected. Power is supplied by 4x AA batteries in portable units, or, optionally, an external DC source. Rack mounting models mostly have an internal switch-mode supply, some are available as alternative models which accept DC power.
