Abstract

A mobile device test module enables a remote client to execute client-developed mobile device applications on a mobile device, via a communication network, to test application performance on the mobile device. The module includes a host compute board which establishes a device communication link, which can include a wireless link, with a mobile device mounted in the module and generates commands to the mobile device based on signals received at the board. The module restricts the host compute board and mobile device to device communication links between each other. The module housing can restrict device communication links with devices external to the module. The module can be installed in a slot of a chassis which can provide structural, power, and communication support to the module. The chassis includes interface clusters which each can support various modules installed in the slots and can support redundant links with an installed module.
