Abstract: Various example embodiments are disclosed relating to wireless networks, such as relating to techniques to improve coverage of push-to-talk wireless networks or services. In an example embodiment, a technique may include forwarding data to a remote push-to-talk (PTT) wireless network via an intermediary device of an intermediary wireless network if the data is received from a wireless device of a local push-to-talk (PTT) wireless network, forwarding data directly to one or more wireless devices of the local PTT wireless network if the data is received from the remote PTT wireless network via the intermediary device, and forwarding data to one or more wireless devices of the local PTT wireless network and to the remote PTT wireless network via the intermediary device of the intermediary wireless network if the data is generated locally.

Abstract: Method, apparatus, and computer program product embodiments are disclosed to improve network performance for ad hoc WLANs save power in service discovery phase and provide service availability information quickly and independently from the wireless channels used in the WLAN ad hoc networks. The embodiments perform link-local addressing, Multicast Domain Name Service (DNS), and DNS Service Discovery operations one or more channels of an ad hoc IEEE 802.11 Wireless LAN. A protocol handler in a wireless device is coupled between a standard service discovery protocol module in the device, such as a Zeroconf protocol module or a UPnP protocol module, and at least one internet protocol stack in the device.
