The Glensound Broadcasters' Mobile Phone 

The GS-MPI004 HD has been designed to solve the problems of using mobile phones for audio broadcast purposes.  It is a 2G GSM phone and also a 3G UMTS narrow band and 7 kHz HD Voice phone.

Glensound engineers have excelled themselves with this design to make life as a broadcaster easy.  If you want a reporter to do a quick interview in the high street, or need to use the phone network for 4 wire communications, or want a reliable back up circuit for a codec, or would like to connect a mixer to a phone or indeed for hundreds of other uses then the GS-MPI004 HD is the answer.

To make broadcasting from anywhere in the World easy the GS-MPI004HD has a QUAD BAND GSM interface as well as 3G UMTS.  This allows connectivity with most of the Worlds mobile phone networks and a SIM card holder, accessible via the front panel, allows different network SIMs or roaming SIM cards to be quickly and easily fitted or changed.

The GS-MPI004HD is battery powered, to prevent it not being charged when you need to use it in a hurry it does not have internal rechargeable batteries but instead is powered from standard readily available AA cells.

The HD Voice audio quality is explained on the next tab, but what about 2G GSM quality? Because the GS-MPI004HD has a digital GSM module the audio quality is the best you will ever get from a phone network. With the audio being in the digital domain separation between the go and return channels is 100% which far outperforms even the very best standard wired telephone hybrids.

Our chief engineer has spent a long time perfecting the compressor/ limiter circuit and the audio input circuits to the phone network for you, the result means that you only need to roughly set the input level and the high quality electronics will make sure that your signal is sent without distortion to the studio.

As you would expect from Glensound mechanically it is housed in a robust custom made aluminium case that is lightweight but extremely strong, so you don't need to worry if you drop it or bash it, it will keep working.

The GS-MPI004 HD is available in a European and a non European version.  The non European version has a 3G frequency of 850 mHz.

All other features of the GS-MPI004 HD are the same as the standard GS-MPI004.  Please click on it below for information.

GS-MPI005 HD STUDIO UNITS
The GS-MPI005 HD is the Glensound HD version of our rack mount Broadcasters' Mobile Phone. Specifications on HD Voice are the same as above, and the main specifications are identical to the GS-MPI005.  Please click on it below for further information.

The additional feature is remote control.  A rear panel RJ45 connects to our own desktop controller the GS-MPI005HD/REMD for full and simple control next to an operators position.  There is also a USB for connection to a PC.  This allows control by systems such as BNCS, or our own PC based software controller, GS-MPI005HD/REMS.  Details of both of these remotes is available by clicking below.

  • 7kHz audio bandwidth
  • Uses AMR-WB (G722.2)
  • HD Voice is a voice call so there are no data or IP issues
  • Operates on compatible 3G UMTS networks (compatible country list on the download tab)
  • Please click the link on the download tab for sample audio

Glensound HD Voice 
The Glensound Broadcasters' Mobile Phone - now with Glensound HD Voice, giving you up to 7 kHz audio bandwidth on a 3G (UMTS) network for the same price as a normal GSM call.  The GS-MPIHD Range features AMR-WB (adaptive multirate wide band), sometimes known as G722.2. This algorithm is more commonly known as HD Voice.  This extra bandwidth makes a significant difference in call quality, with improved lower frequency response and much clearer audio.

A Reliable Connection
Glensound HD Voice connects as a 3G (UMTS) GSM call, not a data call, so when connected you will not lose call quality over the duration of a call as often experienced on an IP call.

If 3G (UMTS) is not available, the call will connect as a standard 2G GSM call. The GS-MPIHD Range can be set to 2G only mode, a 3G (UMTS) only mode or auto. In auto, a connected 3G (UMTS) call will drop back to 2G if you move outside of a 3G (UMTS) signal area. Please note that it will not switch back if you re-enter a 3G (UMTS) area.  Both ends of the connection must be AMR-WB compatible for a HD Voice connection. 

Glensound HD Voice At Large Events
As Glensound HD Voice is just a voice call, it is not affected by the low data rates that are experienced at stadiums and events with 50,000 people.  You do not need to rely on a getting a 2MB connection - it doesn't use the data path.  It simply connects as a normal voice call.  This is the key point that makes the Glensound HD Voice system perfect for reporting or talkback at busy news and sport events.

AMR-WB Availability
Availability of AMR-WB is network specific, and varies from country to country. New countries are enablingf HD Voice all the time.  Please click the download tab for a list of the courrent countries that have enabled the service.

Extra Bandwidth.....for free!!!
HD Voice is a transparant and free service.  So the GS-MPIHD range will just work on 7kHz, at no extra cost over a regular 2G GSM call. Remember, the network sees this as a voice call, not a data call
