Third, the new network attention
Home to work, as long as the front of the LCD touch-screen click start "working mode," then all the family room lights will go out, curtains associated automatic, energy-saving appliances into the state, gas and water valves are shut down automatically, home monitoring equipment and infrared alarm systems automatically open.
In the office in front of a computer, you can operate remotely via the Internet at any time camera view of the situation at home, once in the illegal invasion, the system will automatically report to the Community Center property or their household telephone numbers on the set.
On the way home, you can start by 3 G mobile "home model," opened earlier air-conditioning, curtains, water heaters, and so on, such a home, you will meet the appropriate temperature, lighting and take comfort in the bathtub full of hot water .
In addition, you can relax at home watching broadband TV, the video conference, play interactive games.
……
These wonderful is the vision of our future digital home network (Digital Home Networking). Home network is the telecommunications network from the "last mile" to the "final meters," the extension of modern communications network will be extended to individual households every corner, through the computer, cell phone, PDA to control all families intelligent terminal to help People realize more humane and intelligent modern family life.
Specifically, the network will break the previous family by telephone and computer communications applications as the main mode of family replaced Gateway centre for the control and management will be within the scope of the family computer, telephone, digital home appliances, security systems, lighting systems, as well as other intelligent terminal and WAN link, thereby achieving a family of multimedia communication, entertainment, security and intelligent home control application experience for the digital home network. Home Network will give people more efficient and convenient modern lifestyle.
The home network is the core of the family gateway (RG, Residential Gateway), it can set DSL MODEM, routers, WLAN AP, Bluetooth AP, VoIP, USB applications, as well as more complicated business, anti-virus, intrusion prevention, and other integrated function is the digital home of the key services and applications, the entire home network with external networks linked to the bridge.
Fourth, the new space-time wireless
Now HSPA rate is still relatively low, HSPA + came into being, HSPA + in the air interface is part of the introduction of MIMO-FODM technology to redesign the wireless access network architecture and protocol stack, is a new mobile communication systems.
The Evolution of 3G LTE technology progress rapidly, plans to complete the standard in 2007 enacted in 2009 can be commercial. Its objective is to improve throughput and spectrum utilization, achieve 5 MHz downlink bandwidth of 25 Mbps, up 12.5 Mbps. HSPA + can reuse Release7 wireless access network to achieve, but there are some changes, and likely to RAN, CN the redrawing of the functions; the existing NodeB try not to have an impact, based on the reuse of hardware upgrades . Laws against UE structure of the agreement have an impact, but also with the R99 and HSPA common carrier terminal.
3GPP evolution of the two routes: First, the transition from direct to the LTE HSPA, Span, backward compatibility bad; two from the HSPA evolution to HSPA +, the final evolution to LTE, backward compatibility, and to protect the existing investment. The relationship between the two is not competition, HSPA + only it is a transitional role, will eventually be unified to the LTE. Experienced FDMA, TDMA, CDMA, the core technology is 4G OFDM-MIMO.
At the same time is to be noted that, with regard to WIMAX and the three G's arguments, both different from the original starting point, "Mobile broadband access" and "broadband mobile communications," the two are mutually absorbed in the technical integration, development Goals are the same. As for after development is the coexistence and integration of an election or two, is more dependent on the development of the industry chain, competition, regulatory policies, and other non-technical factors. WIMAX has a clear commercial and business plans is the South Korea and the United States, South Korea's KT WiBro business has been working in the 2.3 GHz band, 9 MHz bandwidth, uses OFDM / TDD, the rate of downstream 6.1/18.4 Mbps. Sprint-Nextel plan the United States in 2007 using 2.5-2.69 GHz band, providing portable and nomadic early scenes, the follow-up support mobile handsets and PDA.
