    Abstract: Various embodiments disclose systems and methods for employing a Sub1G signal (e.g. a signal in the range of approximately 500 Mhz or 800 mHz) for use with internal and/or external components of various user devices. The Sub1G region may provide a path loss advantage over traditional 2.4 and 5 Ghz systems because of the lower frequency in free-space path loss model. Sub1G may also present less interference compared to 2.4 GHz (e.g., better QoS for applications such as VOIP, Gaining, etc.). In some of the disclosed embodiments, Sub1G may be employed using current 2.4G or 5G Wireless LAN chipset with RF Up/Down Converters. In some embodiments, the Sub1G approach may be used to create a Long Range Bridge, Long Range Extender, Long Range Client, Long Range Hotspot, etc.

    Abstract: Systems, processes, and structures allow enhanced near-field testing of the uplink and/or downlink performance of MIMO wireless devices (DUT), such as for any of product development, product verification, and/or production testing. Signal channels may preferably be emulated to test the performance of a device under test (DUT) over a range of simulated distances, within a near-field test environment. An enhanced process provides automated testing of a DUT over a wireless network, e.g. such as but not limited to a WLAN. The enhanced MIMO channel emulator may preferably be operated over a high dynamic range.

    Abstract: Systems and methods for improving wireless access point communications are provided. Some embodiments contemplate filtering operations such that two or more radios can be used in the 5 GHz or 2.4 GHz band without interfering with each other. Some embodiments employ discrete Low Noise Amplifiers (LNA) and Power Amplifiers (PA) as well as frontend modules. In some examples, filtering may be primarily used on the receiving side to filter out other signals in 5 GHz before they are amplified by an external LNA or LNAs, e.g., as integrated in a WLAN chipset. Filtering may also be performed on the transmit side in some embodiments.

    Abstract: A receiver is provided that receives signals from a device under test (DUT) for one or more modes of operation. For each mode, the system detects beacon transmission signals from the DUT, and counts the number of beacons for a period of time. If the count is not consistent with an expected count, e.g. a stored value, the system may preferably provide an output to indicate that there is a problem with the DUT. If the count is consistent with the expected count, the system may preferably perform further testing for other modes of operation. If the count output of the DUT is consistent with expected counts over each of the operation modes, the system may provide an indication that the DUT has passed the beacon tests.
