iOS somehow reduce my network speed in Wifi connection to my Camera device in AP

I'm developing iOS Application for communication with manufactured Camera via WiFi using custom API.

I have camera device in Wifi mode AP. I'm connecting to that device via Wifi using NEConnection to specific port. TCP protocol.

We have 2 ports, one for messages other for data transferring.

Then using API. I'm building specific message, converting them to Data and sending to Camera device. I can receive data or message data from Camera as well.

I need to download video file with for example 100MB. And it take a lot of time.

Issue is: While receiving data from device we have speed ± 160 KB/s, but android with the same configurations has 2MB/s.

Why it happens, does Apple makes some speed limitation? Could it be related to Wifi as it doesn't has internet connection?

NWConnection constructor:

static func createConnection(host hostAddress: String, port portInt: UInt16) -> NWConnection {
        let ipv4: IPv4Address = .init(hostAddress) ?? .any
        let host: NWEndpoint.Host = .ipv4(ipv4)
        let port: NWEndpoint.Port = .init(rawValue: portInt) ?? .any
        
        let tcpOptions: NWProtocolTCP.Options = NWProtocolTCP.Options.init()
        
        return .init(host: host, port: port, using: .init(tls: nil, tcp: tcpOptions))
    }
