Triple play (telecommunications)
In telecommunications, triple play service is a marketing term for the provisioning, over a single broadband connection, of: two bandwidth-intensive services, broadband Internet access and television, and the latency-sensitive telephone.〔(Tech Home Builder ) Revenue streams〕 Triple play focuses on a supplier convergence rather than solving technical issues or a common standard. However, single standards like G.hn do exist to deliver all these services on a common platform.
== Quadruple play ==
A so-called quadruple play (or quad play) service integrates mobility as well, often by supporting dual mode mobile plus hotspot-based phones that shift from GSM to WiFi when they come in range of a home wired for triple-play service. Typical Generic Access Network services of this kind, such as Rogers Home Calling Zone (Rogers is a large cable television and cell phone service provider in the Canadian market), allow the caller to enter and leave the range of their home Wi-Fi network, and only pay GSM rates for the time they spend outside the range. Calls at home are routed over the IP network and paid at a flat rate per month. No interruption or authorization for the shift is required—soft handoff takes place automatically as many times as the caller enters or leaves the range.
