Computer networks and their benefits have made inroads into an average household. More households are connected to the internet through broadband access services. This requires using internet protocol for addressing and enables devices in households to share resources. A home area network (HAN) is a computer network that operates within a house or small office/home office (SOHO) and connect digital devices within the home security systems and smart appliance. HAN facilitates the communication and inerrability among the digital devices. It allows them to share resources and have connection to the internet. It is capable of increasing personal productivity and enhancing home security. GET YOUR ASSIGNMENTS DONE BY TUTORS AT AFFORDABLE PRICES.
Home area network emerged as a result the dramatic growth of internet in the late 1990s. A typical HAN is composed of four elements: A gateway that connects the HAN to the outside networks such as the LAN or WAN; the access points; a network operating system; and smart endpoints such as smart meters, refrigerators, and appliances. HAN technology enables one to remotely connect and control many interconnected digital devices within the appliance. HAN technology enables one to remotely connect and control many interconnected digital devices within the house.
Traditional information networks were formed of similar components comparable in terms of power, storage capacity, memory, and bandwidth etc., Home systems networks are comprised of heterogeneous devices. They support HiFi devices as much as mobile and computer device. This heterogeneity has consequences on household networks.
Home networks are particularly dynamic, and in more than one respect. First, a given home network changes over time depending on the devices which comprises it. It start with the first device that the user buys communicating, and evolves over the course of purchase, sales, breakdown, losses, etc. home area network is also physically dynamic the components which form it permanently interconnected: the device can be mobile, live or not; disconnection must be allowed to be made while running and communication channels can be noisy or temporarily available.
Absence of administrator
The user of home networks are very different to those of information networks. Home networks users interact with their devices on daily basis. They have generally benefited from no particular training and can ignore operations of a network. Even when they happen to have specialized skills, they will probably not devote the necessary resource required to configure, administrator and regularly monitor their home area network.
Home area network technologies
Copper pair cables
Copper pair cables are used for short distance, notably for constructing home networks, and are mainly dependent on crosstalk in its different forms. The technology used to combat crosstalk rests on use of several pairs, which are twisted in a way calculated to reduce or to eliminate undesirable emission and reception
The home area network coaxial cables
Coaxial cables can act very well as means of Ethernet transportation to the inside of the home, no matter which internet access provider is concerned , as well as ensuring the connection between various computer type devices such as PCs peripheral devices and servers
Home networks using indoor power line communications
The use of indoor or in home PLC has become an efficient way of connecting several devices, either point to point or using local area networks (LAN). This use occurs downstream from the electricity meter and ensure transmission true the electric pairs inside domestic household
LTE_SAE standards contain a femtocell section, describing a high bit rate distribution systems inside residences. If we imagine that this standardization is followed by industrialization the femtocell can potentially be seen as an alternative for the creation of home networks
Plastic optical fibers
The optical fiber is an optical wave guide transmitting information produced by a laser or LED whose pulses are encoded on order for information to be correctly transmitted over a long distances, the fiber must be perfectly transparent. Silica fiber have remarkable improvements upon current values.
Wi-Fi home area networks
Wi-Fi___33 is widely considered to be contracted of wireless fidelity it is a technology based on the IEEE standard describing the characteristics of a wireless local area network (WLAN). Wi-Fi allows connection of laptops, desktop machines, personal assistants, communicating devices, and in particular peripherals it high rate of links.
Home area networks market challenges
Customer concerns about security based on experience with loss of privacy, well publicized data thefts and security breaches could hinder HAN adoption.
Consumer concerns about interoperability could slow HAN adoption until technology standards mature. Efficient certification process are critical to develop and deploy robust standards that enable vendors to produce compatible products and to reassure consumers.
Mainstream consumer adoption of HAN technologies could be limited until prices for hardware, application and services reaches a level where quick ROI can be demonstrated. The rate of price decline will depend on the adoption of technology standard and the potential for achieving scale efficiencies in creating HAN devices and software.
Strong vendor participation in the HAN market is essential to ensure that a robust set of products, services and solutions with strong customer’s value propositions are offered.
