What is 5 GHz wireless video link

A 5 GHz wireless video link carries compressed video in the 5 GHz Wi-Fi band, which has more spectrum and less interference than 2.4 GHz. Range depends on the Wi-Fi module fitted and on obstructions at the site.Also called: 5.8 GHz video link, 5 GHz wireless HDMI

Why video links use 5 GHz

The 2.4 GHz band is narrow and shared with Bluetooth, ordinary routers and microwave ovens, so a continuous high-bitrate 4K stream stutters easily. The 5 GHz band has much more spectrum and room for several 40 MHz channels, so a video link can move away from other traffic. The cost is weaker wall penetration than 2.4 GHz, which has to be counted when choosing a range tier.

What sets the range

Range is set by the Wi-Fi module fitted, not by video resolution. Output power, receive sensitivity and the number of antennas give each module its own line-of-sight reference distance. Rated figures assume line of sight; reinforced concrete, lift shafts and metal buildings shorten them a lot, so test samples at the real site before production.

Channels and regional rules

Countries open different parts of the 5 GHz band, so modules are programmed with regional regulatory settings and the target market must be stated on the order. At power-up the module scans for a clean channel and can switch while running. The finished product still needs its own certification for each market, and any change of antenna type or layout should be checked with us first.

On ANLYA modules

ANLYA's 4K30 and 4K60 modules operate at 5.15 – 5.85 GHz with OFDM, adapting between BPSK and 256-QAM to channel quality. Range comes in three tiers: AIC8800-D40 30 – 100 m, AIC8800-D80 100 – 300 m and RTL8812CU 300 – 1000 m, all line-of-sight reference values. One TX can broadcast to several RX units.

FAQ

Q1Can a 5 GHz wireless HDMI link go through walls?
It passes ordinary partitions, but range drops. Reinforced concrete, basements and metal buildings absorb a lot of 5 GHz signal, so use cable or fiber between floors or buildings. The module has a built-in Ethernet PHY, so the same module can switch to a wired link.
Q2How far can a wireless video module transmit?
It depends on the Wi-Fi module: AIC8800-D40 30 – 100 m, AIC8800-D80 100 – 300 m, RTL8812CU 300 – 1000 m, all line-of-sight reference values. All three tiers run 4K60; resolution does not drop with distance.
