The HDMI cable has been accepted as the standard for wired HD content transmission, but the race to find the wireless standard is just getting started. There’s no clear winner (yet) in the handful of incompatible standards out there today. We spent a lot of time researching the different wireless options to integrate into the Spontaneous Pop-Up Display. Since we never found a great summary of all of the options, we decided to create one!
Standard | Frequency | Resolution | Max Distance | Video Compression | Connection Type | Latency | Data Rate | |
---|---|---|---|---|---|---|---|---|
WirelessHD | - | 60GHz | 1080p, 60Hz | 10m (line of sight) | Uncompressed | Direct | < 1ms | 10-28 Gbps |
WHDI (Wireless Home Digital Interface) | - | 5GHz | 1080p, 60Hz | 30m | Uncompressed | Direct | < 1ms | Up to 3 Gbps |
WiGig (Wireless Gigabit) | 802.11ad | 2.4GHz, 5GHz, 60GHz | 1080p | 10m (line of sight) | Uncompressed | Wireless Access Point | < 1ms | Up to 7 Gbps |
WiDi (Wireless Display) / Miracast | 802.11(a,b,g,n,ac) | 2.4GHz, 5GHz | 1080p | 7m | H.264 mpeg | Direct | < 150ms | Up to 600 Mbps |
Apple AirPlay | 802.11(b,g,n,ac) | 2.4GHz, 5GHz | 720p/1080p | Range of wireless network | H.264 mpeg | Wireless Access Point | 180ms+ Dependent on network conditions | Up to 600 Mbps |
Google Cast | 802.11(b,g,n,ac) | 2.4GHz, 5GHz | 1080p | Range of wireless network | VP8, H.264 mpeg | Wireless Access Point | 180ms+ Dependent on network conditions | Up to 600 Mbps |
As the battle for wireless dominance continues, we're sure of one thing: We're very excited to see a wireless SPLAY in action!!
