When purchasing a wireless HDMI transmitter, pay attention to which wireless standard the transmitter uses. The WirelessHD standard transmits at a 60-GHz frequency, allowing uncompressed data transfers between the output device and the television. However, 60-GHz signals are prone to interference from other electronic devices, cannot travel over considerable distances, and cannot travel through walls or other obstructions.

Some wireless HDMI transmitters use the WHDI standard instead of WirelessHD. WHDI uses a much lower transmission frequency, at 5 GHz, than WirelessHD. By using a lower frequency, WHDI signals are less prone to interference. Low-frequency signals also have considerably longer range, and they can travel through most walls. However, with WHDI's increased signal strength comes a loss in fidelity. Because WHDI cannot transmit as much data as WirelessHD, devices that use this standard sometimes compress video data, causing minor losses in picture quality.

While the wireless standard an HDMI transmitter uses has a large impact on its picture quality and signal strength, the most important specification for these devices is latency. Latency is the amount of time the device requires for processing data. The lower a transmitter's latency, the quicker it processes data and the lower the likelihood of dropped frames, compressed data or reduced picture quality.
