Traditional network technologies have been left behind by history, so popular new technologies must adapt to social development. The formation of networks in the family also faces many problems, the home network standards and specifications are described here. Wireless voice network-when each wireless phone can view and manage up to four common telephone service (POTS) lines, multiple PCs can be used on the LAN at the same time. The mobile phone display allows users to access caller ID and voice management status information and make call management decisions in real time.
Traditional line POTS network-all telephone lines in the home are connected to the Controller. Then the telephone line is assigned to a wireless phone or a wireless RJ-11 telephone outlet with a built-in transceiver, while a standard phone, fax machine, or a PC with a modem can be connected to a wireless phone outlet.
This non-PC-based switch center is software-based, so that new network needs in the family can be met without large-scale changes.
Home network standards and specifications-1 standards
Standards, whether published by standard organizations or published by leading system vendors as fact standards, will play an increasingly important role in system development. Many different formats of standards and specifications are emerging on the home network, including the following:
IEEE 802.11 Wireless LAN-the IEEE 802.11 standard defines protocols for two types of networks, namely temporary networks and client/server networks. A temporary network is a simple network in which communications can be established between multiple sites in a given coverage area without using access points or servers. This Standard specifies the rules that each site must comply with, so that all sites can access wireless media fairly. It provides arbitration media requests to ensure the maximum throughput for all users in the basic service set. The client/server network uses an access point that controls the transmission time allocation of all stations and enables mobile stations to roam from one cell to another. An access point is used to process transmission streams from a mobile radio to a wired or wireless backbone line of the client/server network. This arrangement takes into account the coordination of all stations in the basic service and ensures correct processing of data streams. The Access Point provides a routing function for data between wireless stations or the data of input and output network servers. Bluetooth radio technology provides a general bridge for existing data networks and peripheral interfaces, a small dedicated temporary workgroup consisting of connected devices can also be built away from the fixed network infrastructure. Bluetooth radio technology designed for noise RF environments uses a fast response and frequency hopping solution to build solid links. The Bluetooth radio module skips to the new frequency after transmitting or receiving data packets to avoid interference from other signals.
SWAP 1.0 -- the SWAP system can run either as a temporary network or as a managed network under the control of a connection point. In a temporary network that only supports data communication, all the sites are equal, and the control of the network is distributed among the sites. A connection point is required to coordinate the system for time-sensitive communication such as interactive speech. The connection point that provides network functions for the PSTN can be connected to the PC through a standard interface such as a universal serial bus that enhances voice and data services. SWAP can also use connection points to support power management by arranging device wake-up and polling times to prolong battery life.
X10-this is a communication protocol that controls and communicates electrical equipment through standard home AC transmission lines.
Home network standards and specifications 2 IEEE 1394
IEEE 1394-this is a serial interface used for short-distance, low-data-rate infrared communication between entertainment and computer devices.
Home telephone line Network Association (HomePNA)-home telephone line network technology must be able to adapt to completely random and nonstandard line topologies. They must also be designed to take into account the unknown but generally high attenuation signal attenuation in the random tree network topology. As a transmission pulse is constantly reflected inside the line, attenuation and diffusion occur on the line. The longer the pulse is transmitted on the indoor line, the more severe its attenuation and dissipation will be. Home telephone line network technology requires a variable and high signal noise level, must tolerate Dynamic Transmission Line characteristics, and can coexist with telephone services and comply with the Federal Communications Commission (FCC) part 68 specification. Finally, they must achieve the maximum data throughput under the above constraints and restrictions.
Hwn sserq/AAWG-The SSERQ protocol is optimized for wireless voice, data, and multimedia services. Its Packet retention solution provides QoS and access priority required for voice and multimedia services. Broadband and public channel signaling enable the rapid establishment and removal of Virtual Private circuits for high-speed Intranet transmission streams and Internet access. SSERQ uses the air-to-air wireless gateway to support the IEEE 802.11 infrastructure (Client/Server) network. The air-to-air wireless gateway provides the conversion, management, and transmission between the 802.11 and SSERQ networks.
