Respond to of 46821 The term femptocell is already being used to describe products announced by Alcatel, Nortel and others to extend and enhance 3G networks to allow them to serve as a local data a well as cellular voice network. WiMAX is taking steps to standardize the basic organization and methods, such as how control is orchestrated between the centralized service network and distributed granular cells or pods of cells. This will be an extremely active area of commercial development because the needs are so apparent and benefits are so easily demonstrated. At this point, femptocell is being demand driven for both 3G cellular and WiMAX deployments. This shifts from this being more a talking point with few examples and little sales momentum. It has already grown rapidly during the past several months to become a noticeable and rapidly growing part of cellular systems sales. And it will become much more important to WiMAX if for no other reason than the increased data densities. The media loves to latch onto single or limited numbers of terms to describe technology developments. It looks like "femptocell" will be coined as a term to describe a broad ranage of capabilities. It does dscribe use of very small base stations/routers which is appropriate to paint a picture about the granular nature of the networks without going into the details that often confuse the public. When I say Ethernet, that is because that is the predominant protocol that data communications is migrating. But the wireless and wired systems are all multi-protocol: even small cell phones and portable devices have several modes of operation and can connect to packet-switched, PSTN, VoIP, cellular, WiFi, WiMAX and other networks. If a personal entertainment center connects using UWB which, in turn, connects to services over cable, DSL to digital media and Internet feeds, PtP and on demand services, major portions of most of these will be Ethernet based. New satellite networks planned for deployment will use WiMAX communications protocols which are based on DOCSIS & Ethernet.
