4G wireless nomadic devices in the form of USB dongles and Pocket modems are fast becoming the preferred devices for wireless broadband access amongst 4G operators. Due to benefits of lower cost and smaller form factor, 4G wireless nomadic devices now account for 39%* of total WiMAX devices shipped in 2010, and this tendency is set to continuously increase in the coming years as 4G becomes pervasive.
Greenpacket 4G nomadic devices now provides an option to allow the use of generic Virtual Ethernet link protocol (USB CDC or RNDIS) to connect with these external host controllers running on any operating systems as an alternative to the traditional CU approach. We call this feature “Hostless” connectivity. Very similar to how an end-user would connect a USB memory stick, this new Hostless feature can be visualized as a generic version of a CU, borrowing the native USB Ethernet driver and management features from the host operating system.
This paper explains the implementation scenarios of both the CU approach and Hostless approach to match specific needs. We will then dive in detail to understand the concept background of Hostless by looking at the system architecture and describing the step-by-step of how Hostless works within the host terminal from an end user perspective.
