When USB3.0 can also lift the charge efficiency of terminal device, so as to improve the Experience Degree of user.At present
USB3.0 interfaces are mainly used in personal computer (Personal Computer, PC), mobile hard disk, USB
The terminal device such as flash disk and card reader.
But USB3.0 is while above-mentioned advantage is brought, corresponding problem, such as use of USB3.0 are there is also
Aerial download (Over The Air, OTA) performance of terminal device can be influenceed, that is, influences the whole machine spoke of equipment
Penetrate performance.The OTA parameters for embodying the OTA performances are broadly divided into two classes：Receive parameter and emission parameter.
Emission parameter includes total radiation power (Total Radiated Power, TRP), and the parameter is by whole spoke
Penetrating the transmission power of sphere carries out Line Integral and is averaged to obtain；Near-earth horizontal line partial radiation power (Near
Horizon Partial Radiated Power, NHPRP), the parameter is reflected in antenna near the H faces of equipment
Transmission power situation.Receive parameter include isotropic sensitivity (Total Isotropic Sensitivity,
TIS), the parameter is reflected in the situation of whole radiation sphere equipment receiving sensitivity；Nearly level is local each to same
Property sensitiveness (Near Horizon Partial Isotropic Sensitivity, the NHPIS) parameter reflection equipment exist
The situation of the receiving sensitivity of antenna near H faces.
Specifically, as shown in Figure 1A, Figure 1A shows that the USB interface in data card does not transmit data
In the case of, for the wireless signal of different frequency range, the TIS parameters that correlation standard data card should reach
