Range of Network / Multipeer

Since Apple Multipeer framework does not really work without crashes, I implemented my own multipeer with the Network.framework. like

 let tcpOptions = NWProtocolTCP.Options.createDefault()
        let parameters = NWParameters(tls: NWProtocolTLS.Options(), tcp: tcpOptions)
        parameters.setDefaultSettings()
        let browser = NWBrowser(
            for: .bonjour(
                type: config.bonjourServiceType,
                domain: nil
            ),
            using: parameters
        )

and

extension NWParameters {
    func setDefaultSettings() {
        self.includePeerToPeer = true
        self.requiredInterfaceType = .wifi
        self.preferNoProxies = true
    }
}

extension NWProtocolTCP.Options {
    static func createDefault() -> NWProtocolTCP.Options {
        let tcpOptions = NWProtocolTCP.Options()
        tcpOptions.enableKeepalive = true
        tcpOptions.keepaliveIdle = 10  // 10 seconds keepalive interval
        tcpOptions.noDelay = true      // Disable Nagle's algorithm for low latency
        return tcpOptions
    }
}

it works well up to approx. 30 meter outside with free view. What's the max range for the peer to peer via bonjour? And is there a way to get longer distance than 30 meter?
