BRAVIS video conferences - Video conferences on mobile devices

With laptops, notebooks and tablets, the demand for mobile video communication solutions that can conveniently enable exchanges between more than just two participants has also increased. Especially for employees who are regularly out and about during office hours, the option of being able to communicate audiovisually with colleagues, customers and business partners at any time is advantageous. “Certain guidelines must be taken into account to achieve the best results,” according to André Röhrig, managing director of BRAVIS International GmbH,

Bandwidth: For users of mobile devices, the first issue is that of ensuring the necessary bandwidth for video calls. 4G LTE, the 4th generation high-speed mobile radio standard, is by no means available everywhere. This hurdle can be avoided by the BRAVIS application solution, which only requires 2 to 2.5 Mbit per second even for the best full-HD quality, in order to ensure interference-free transmission. This even works if WLAN is only available with 3G standard (up to 42 Mbit) or with UMTS (up to 21 Mbit). In the case of poor transmission capacity, BRAVIS also prioritises the audio stream over the image data, which ensures stability for calls.

Confidentiality: In many business and private sectors, confidentiality and reliable protection of important data have not only become essential and, in some cases, legally prescribed since NSA, etc. (for example, for doctor-patient confidentiality). This is no less necessary for video communication by notebook or tablet. In this case, BRAVIS offers a fundamental advantage over virtually all other providers with its group communication protocol, with which the devices of participants can interact directly with one another (peer-to-peer): This is done without interconnected servers – the “classic” gateway for unauthorised listening in by third parties.

Documents: In comparison with users of other mobile video communication solutions, BRAVIS users can also transmit, share and edit documents during a conference. If necessary, the video image can be temporarily switched off to do this.

Background: The cameras that are normally built into mobile devices do not just show the participants of the video call. For this reason, the surroundings also play a role in effective communication. In particular, lively backgrounds with constantly moving people or traffic should be avoided as far as possible.

Lighting: Backlighting and direct sunlight should also be avoided so that the participants do not appear very dark. The suitability of the intended location and possible alternatives can be checked before the start of the call using the BRAVIS thumbnail.

Acoustics: The capacity of the internal microphones and speakers of mobile devices is not always adequate for a high-quality video conference. However, the speech and audio quality can normally be considerably improved through cost-effective headsets. Preference here should be given to “wired” rather than “wireless” headsets.
