music/video center, synchronized with the new iTV server, as well as the Wi-Fi-enabled iTouch. The vision consolidates around the iPhone, the new central device for bringing the connected home together. Companies like Nokia and Sony/Ericsson are working to leverage their strenght in the mobile device market to develop similar strategies. have developed a protocol for bringing devices into this connected home network. In an HZ2.0 application, the handset can become part of the network through a native Wi-Fi connection and DLNA application running on the phone, or via proxy through a DNLA-enabled femtocell. In fact, Nokia and Samsung both recently announced their first DLNA-supported, dual-mode Wi-Fi handsets. called "Soft At Home." This joint venture with Sagem and Thomson has the stated goal to "facilitate the deployment and interoperability of digital equipment in the home." improve coverage and offer low-cost mobile calling to their subscribers. These benefits are being realized today by innovative operators such as Orange and T-Mobile US, among others. Yet the vision for HZ2.0 is to develop a long- term connected home strategy that cements the mobile operator as the service provider of choice for in-building communications and puts the mobile phone squarely at the center of the next generation in-home network. network alone does not support the fundamental requirements of an HZ2.0 service: a radio-based `service zone' to differentiate services from the macro network, the use of broadband to offload data intensive services from the macro network, and improved coverage/performance delivered from an in-building radio (femtocell or Wi-Fi). operators. In short, HZ2.0 lets mobile operators own the home. destinations. But with the rise of flat-rate data pricing, there is no significant revenue opportunity for mobile operators offering access to these sites from within the home zone. In addition, data-intensive traffic has the ability to choke mobile network resources. directly to the IP network. HZ2.0 services based on Wi-Fi or femtocells inherently support this local data offload capability. accessed over the cellar network. However, new UMA- enabled handsets from Research in Motion (RIM) support internet offload concurrently with UMA. When in Wi-Fi, mobile services like voice and SMS are delivered through the UMA tunnel, while internet applications like Google or YouTube are routed directly over Wi-Fi. feature. Traffic from the handset is passed into the femtocell, which then can route the request based on IP address or APN to the mobile core network or directly to the public internet. |
