The SHO-V2/3RLAP and SHO-V2/3LLAP (SHO Right and Left LAPtop hands) are a pair of homogeneous anthropomorphically shaped hand phan-tom designed to test the effect of the users hands on the over-the-air wireless performance of laptops, notebooks, and wireless keyboards. The hand size and material correspond to those dened by CTIA and 3GPP and represent average hand size.
The hand posture represents the average resting position of the hand on the English keyboard, i.e., the thumbs on/close to the space-bar, the right index finger on/close to the J-key and the left index finger on/close to the F-key. To allow accurate and repeatable positioning of the hands on the device, supporting low-loss spacers have been integrated into the hands.The hands are mounted on the DUT with Velcro tape (glued to the spacers).
A laptop fixture that allows to adapt various sizes of laptops, notebooks,and keyboards to be adapted to a turn table with its rotation axis aligned to the center of the DUT is currently under development. SPEAGs laptop fixture is recommended but not required for the test.
