Glensound HD Voice
Glensound HD Voice je automaticky aktivovaná funkcia v kompatibilných sieťach a použití dvoch Glensound HD Voice zariadení. HD Voice je AMR-WB, tiež známy aj ako G.722.2 algoritmus, ktorý prináša oproti štandardnému hlasovému prenosu výrazne zlepšenia:
– dvojnásobná šírka pásma 50Hz – 7kHz (2G sieť používa 300Hz – 3,4kHz)
– 12,65 kbit/s a vyššie bitové rýchlosti
– lepšia nízkofrekvenčná citlivosť už od úrovne 50Hz (2G až 300Hz) pre prirodzenejší hlasový prejav
Glensound HD Voice nepoužíva dátovú sieť, jedná sa o štandardný telefónny hovor. To znamená, že šírka pásma je konzistentná, zatiaľ čo šírka pásma dátových prenosov sa dynamicky mení. Ak teda raz prebehne spojenie hovoru, kvalita sa nemení. Naviac, HD Voice funguje aj v husto osídlených oblastiach, kde dátové rýchlosti typicky klesajú na minimum.
