The same frequency band Wireless TV to TV Sender and Wifi router may cause interference

At present, many new types of Wifi router with dual frequency as popular selling feature, some of Wifi route support double frequency band, so what’s is dual frequency band ?

2.4GHz and 5.8GHz are two frequency bands, does not affect the transmission speed.

Some of clients may think wireless 5.8ghz is much faster than 2.4ghz? Just like mobile 4g is fast than 3g and 2g, but actually, 5.8ghz is a frequency band, the same with 2.4ghz, there is no difference between 2.4ghz and 5.8ghz, it’s like two road, there would influence each other, but for 3G and 4G in mobile phone, it’s means generation 3 or 4 communication technology , so the upload and download is difference.

Then why put forward 5.8ghz?

It’s because there is many 2.4ghz wireless device, also 2.4ghz frequency can contain 11 band, but with time goes by, all kinds of IT device become common, like most of iPad, 2.4ghz Wireless TV to TV Sender, mobile, PC, Game player, Bluetooth, wireless mouse use 2.4ghz frequency, then it will cause interference.

Advantage and Shortcoming of 5.8ghz

The advantage is 5.8ghz has anti-interference than 2.4ghz since most of wireless device in the market is 2.4ghz. But the penetrate ability is weak than 2.4ghz, The higher frequency the worse penetrability.

2.4GHz and 5.8GHz is simply the two band for Wifi router, 5.8GHz is mainly to solve the problem of 2.4GHz too congested, both in the transmission speed and no difference.

Smart wireless tv sender installation | PAKITE

Wireless tv sender(also known as video sender, Digisender, or wireless av sender), is a wireless transmission device to share cable tv signal wirelessly in different room and different floor. It's installation is very easy, no matter for RCA/AV port tv sender, or for HDMI tv sender, but it still some details need to be attention.

Like smart tv sender support two group av input and 38/56KHz frequency band IR Remote control. But we have to make sure transmitter and receiver should be in the same channels, or it will be can’t work.

Transmitter and Receiver should be keep on same channel(RCA or HDMI).

a. 433MHz Wireless access C1-C8 should be same, normal control at receiver will be ok.

b. Keep IR Remote control frequency band F1/F2 should be same, normal F1 is 38KHz frequency band and F2 is 56KHz frequency band.

c. Since smart tv sender support two group av input, so transmitter signal input is AV1, then receiver signal output should be AV1.

d. Keep av transmitter and receiver was in the same channels, like transmitter was 01 channels, then receiver should be 01 channels. If for other Dial switch also should be same.

e. Keep both transmitter and receiver was in the same channels, then you can adjust the above function at receiver ends.
