So something like "push to talk" is coming back to mobile phones. The more things change, the more they stay the same. Oh, maybe push-to-talk has never gone away.[1] (It's not a feature offered by my cell phone carrier.) The article kindly submitted here with the interesting new news about phone-to-phone LTE communication reports, "In theory, LTE Direct could be used to create communication apps that route all data from device to device. Some chat apps can already use Wi-Fi and Bluetooth to link up nearby phones, but LTE Direct could offer extended range and better performance. However, carriers will control which devices on their networks can use LTE Direct because it uses the same radio spectrum as conventional cellular links. Wireless carriers might even gain a new stream of revenue by charging companies that want to offer services or apps using the technology, Qualcomm says." As usual, the actual implementation of this service will be all about carrier policies and business agreements.
