1 Marketing Definition and Requirements This section shall contain consolidation of the process in product marketing. It is acceptable that spec can be a bit loose in this chapter but subsequent chapters leave no room for loose specs. 1.1 General Description The product is a Bluetooth-enabled USB audio device intended to be used as an accessory for standard industry PCs. It is designed to work with BT headsets as long as they adhere to the Bluetooth 2.0+EDR specification supporting the headset Bluetooth profile than bi-directional audio streaming. The product targets primarily the ingenuous consumer or first-time headset user who appreciates a hassle free truly PnP solution which operates instantly without requiring neither configuration nor any installation of software, driver etc. 1.1.1 Market Problem Due to an increasing interest in convenient VoIP services on standard industry PCs, where headsets are a prerequisite, there is a growing demand for inexpensive, easy to install and easy to use cordless headsets solutions. 1.1.2 Product Problem Originally BT headset intended to be used with Mobile phones supporting voice services only. Existing BT implementations on PCs consist of built-in BT components or external accessories, like USB dongles, with BT functions and additional BT SW. This PC BT implementation compared to built-in BT in telephone handsets is much more complex (normally supporting many more profiles), and more focused on data use instead of voice services, even if those solutions are capable supporting, e.g. headset or head-free profile. 1.1.3 Technology Problem For BT support in a PC environment a BT Host protocol stack/SW needs to be operated on the PC. This software needs to be installed, managed and launched by the user on the PC before the headset can be paired and used for e.g. VoIP services. This kind of use is much more complex and challenging for the user compared to the BT telephone implementation/use case. 1.2 Key Features, Benefits and USPs This section is informative. This is a list of new, essential and unique features which differentiates the product. Feature Benefit, explanation, comment Mono and Stereo capabilities on same hardware platform Core unit performs as a mono / voice solution (=Leopard). Firmware is user upgradeable to additional stereo operation. In this state the product converts into a mono/voice plus stereo streaming device depending on BT HS capabilities (=Swan). Ease of use Leopard (and Swan) is a truly PnP solution not requiring any specific driver or installation of dedicated software for basic operation. Even though Leopard is state of the art in terms of MS Windows operating system (XP or higher) support with MS standard USB and audio drivers.
VoIP client / softphone support Implementing the newly developed GN USB standard the device will be compliant to the Microsoft Unified Communications (UC) standard. A variety of VoIP clients and/or softphones using the current GN USB HID commands (8120, 9300 series) will also provide basic headset supported without additional customization. The product is fully compliant with GN’s PC software developments and SDKs (Hector).
