the bluetooth in the ds4 is crap.
google for tons of people having issues where they didn't with a ps3.
the first one i googled a guy used to be able to control his ps3 from a different room through walls which was connected to his home network of hdmi cables so his console was able to be displayed in multiple rooms throughout the house.
replaced ps3 with ps4 and was unable to do this due to lag or simply no connection at all.
another guy saying he used to be able to control his console from the kitchen or dining room iirc and now had issues.
i have a bluetooth yamaha soundbar, bluetooth smart tv, tablets, smartphones, wireless router (console is wired) all in the same room. so it could be congested. but i think it's an issue witht he console or the ds4 itself that they have put cheaper parts in to make the console cheaper to manufacter.
otherwise you wouldn't be able to google tons of people all having the same issues.

"It’s bad enough that the PS4 is stuck on an older 2.1 standard of Bluetooth – not even the lower powered standards have been implemented, which might have improved battery life on the controllers – but is the Bluetooth range worse than it was on the PlayStation 3?
With the PS3 users would happily find that their controllers would work from the other side of their house. The PS4 should, theoretically, be the same. None-the-less many users are reporting communication issues from just the next room.
My PS4 is in a different room to my TV – the PS4 is literally behind the wall that the TV is mounted on and is less than 1.5 metres from where I sit. However, I often find a sudden lag occurring between my controller and the PS4.
So, what could the cause be? There are 3 possibilities, or a combination of them…
It’s under-powered in the PS4
The location of the transmitter is causing reception issues
The Dualshock itself is to blame rather than the PS4
Let’s look at what differences there are between the implementation.
On the PS3, a teardown of the PS3 Slim shows the Bluetooth antenna in the lower left hand side of the console, attached to 3-dimensional metal connectors. It uses a Marvell 88W8780 combination WiFi/Bluetooth chipset, although specifications for this don’t seem to be available.
A teardown of the PS4 shows the Bluetooth chip to be on the rear left of the console (looking at it from the front). Instead of a physical cable the chip is connected to a right angled plate via a connector on the motherboard. The Marvell 88W8797 chipset used is a combination WiFi/Bluetooth/RDS radio set-up and it supports Bluetooth 4 (maybe a future software update will allow this).
What the latter chipset shows is that it supports both Class 1 and Class 2. Class 1 allows a range of up to 100 metres but consumes 100mW to do so – Class 2 only allows a 10 metre range but consumes just 2.5mW. Is there a possibility here that the PS4 has switched from Class 1 to 2 to ensure that carrying audio to the controller doesn’t dramatically impact controller battery life? Indeed, the Bluetooth in the controllers themselves are also critical but Sony has released little information about these. A Sony FAQ for the Dualshock 3 states that the range is 30 feet – that is consistent with a Class 2 device. If the PS3 was Class 1 I would have expected this range to be greater.
So, conclusion? We don’t have one. Without firm details of the Dualshock 3, 4 and PS3 Bluetooth we can’t ideally compare. Certainly, it would appear that the positioning and configuration of the Bluetooth within in the PS4 is not as good as the PS3. If you’re having issues I’d make sure that left hand side is as close to the controllers as possible.
Sadly, long term, there isn’t a solution – there doesn’t appear to be such a thing as a Bluetooth extender (shame)."
like i said i've had these issues for a while and the only solution was to remove the console from the av unit. the signal is so weak it cannot penetrate my mattress.
i have a top of the range parrot kit in the car and i've been able to play music inside the car whilst im in the home from my phone. so i assume my car uses the 100m range chip (class 2).
the ps4 or ds4 is using the 10m range (class1).
it's a design flaw.
