Advantages and disadvantages of wide area network

Wireless LAN is made by connecting different devices through wireless communication to make a local area network. WLAN connects laptops, smartphones, personal digital assistants, desktop computers, workstations and printers.

This network is easy to install and use at the home or any other place. AP sends and receives radio frequency signal to the connected devices. In WLAN installation was expensive and was only deployed where the wired connection was not possible. It works with a bandwidth of 2. The devices which WLAN connects are also called clients. WLAN gives a high data transfer rate.

It works better in homes and offices. Especially in offices no extra cables are required and arranging a meeting is also easy. It has a data transfer rate of Mbps. It also uses infrared technology if required. WLAN is used to make a limited network in school, home, campus, computer laboratory and office building. Your email address will not be published.

Remember me. Forgot password?This wireless wide area network WWAN primer gives WAN managers and engineers a brief overview of the technology -- including what a WWAN is, why you need to know about it and what you need to know about it.

A wireless wide area network provides coverage to a large geographical area by connecting separate areas of coverage wirelessly. WWANs are usually publicly shared data networks owned by service providers with low data rates based on usage.

Wireless local area networks WLANson the other hand, are typically privately-owned networks that cover a smaller area such as a warehouse, hospital or educational institution with data rates based on usage. Currently, WWANs are primarily used for smartphones and other handheld devices offered by cellular service providers. There are several possible applications of WWANs. One of its uses is for a backup connection in the event of a WAN outage.

Using a WWAN for this purpose could save money since it acts as an on-demand backup, which bills by usage -- rather than as an always-on connection, which bills an invariable fee. WWANs can also act as a stopgap measure when setting up a new remote branch or temporary location while the primary access is being installed, removing wait time for those sites.

WWANs could even be used as the primary access at remote sites if a wired connection would be too costly. Can 4G wireless WAN links serve as more than a backup? Wireless WAN services : Myths versus reality. Although 3G services would not be the ideal primary network access due to their limited bandwidth, the emergence of 4G services offers new possibilities for wide area network access.

WWAN services offer a few advantages, including being less costly than wired infrastructures and having the ability to deploy quickly. Although service providers have not historically offered 3G and 4G network performance guaranteesthis problem is starting to be addressed.

Sprint Nextel Corp. However, pricing may prove problematic due to the ending of unlimited data, which may make it too costly to use the WWAN as the primary access.

Since this technology is still evolving, WAN managers should plan ahead if they wish to switch to wireless WANs in the future.

advantages and disadvantages of wide area network

LAN connections can only operate in a local area which is usually not any bigger then a house, or a floor in an office building. Typically a LAN will consist of only a handful of clients, but can have upwards of a hundred. One of the major advantages with LANs are the speeds they can reach. Another advantage to having a LAN connection is the cost. It is relatively cheap to have as it tends to require less hassle to set up and less advanced infrastructure to keep it running.

This is mainly due to the technological components of a LAN, which brings me to the next difference. A LAN connection tends to require some relatively simple things to set it up. All you need is some Ethernet cables, a network switch, and you are good to go. Alternatively, you can also see LANs being done over Wi-Fi, or you can use Wi-Fi in conjunction with standard Ethernet connections to create a LAN available to all kinds of devices, whether it be a smartphone or a desktop computer.

The major disadvantage with a LAN is inherent in its name. Simply put, you cannot buy an Ethernet cable that will reach throughout an entire building, and a Wi-Fi connection rapidly deteiorates as you get further then a few dozen meters away.

A WAN connection should truly only occur in large environments. WAN connections are available from house to house, city to city, and country to country.

In fact, just by reading this you know you have access to a very popular WAN, the Internet.

1. What is a WAN

The further the distance, the slower the network. One of the big disadvantages to having a WAN is the cost it can incur. Having a private WAN can be expensive. The reason that WANs cost a lot tends to be because of the technology required to connect two remote places, which brings me to the explanation of the technology behind a WAN.

A WAN connection is generally harder to set up, and there are many creative ways to do so. Another way to do a WAN is connecting the devices with various wireless technologies, like cellphone towers or satellites. As you can imagine, all these are much harder to create than setting up a LAN and almost always demand high level professional setup and maintenance.

What Our Customers Have To Say

Computer hardware resources like printers, modems, DVD-Rom drives and hard disks can be shared with the help of local area networks. This will reduce cost of hardware purchases. For example, a business organization using a Local Area Network for an office can use a single network printer for the employees of this office. It is cheaper to use same software over network instead of purchasing separate licensed software for each client in a network.

It will cost more to purchase a separate licensed software for each computer in a network. Data and messages can easily be transferred over networked computers. It saves a lot of time and money. The data of all network users can be saved on hard disk of the server computer.

This will help users to use any workstation in a network to access their data. Because data is not stored on workstations locally. But it is stored on a server computer. User will access their own data by logging into their accounts from any client computer in the network. Since, data is stored on server computer centrally, it will be easy to manage data at only one place and the data will be more secure too, because of more security for the server computer.

Local Area Network provides the facility to share a single internet connection among all the LAN users. In Net Cafes, single internet connection sharing system keeps the internet expenses cheaper.

Because only one high speed internet connection is purchased by a net cafe from any ISP - Internet Service Provider company.

This single high speed internet connection is managed on the server computer of the Net Cafe and available for all network clients with the help of Internet Connection Sharing facilities of the operating system. Although the LAN will save cost over time due to shared computer resources but the initial setup costs of installing Local Area Networks is high.

This is because any organization that will setup a network, will have to purchase necessary hardware equipment for networking. Additionally a Network technician will be required for setting up a new network in an organization. If an organization has a large network, it must hire a network administrator for smooth running of network and solving any problems. Moreover he can check the internet history and computer use history of the LAN users.

Unauthorized users can access important data of an organization if centralized data repository is not secured properly by the LAN administrator. LAN Administer is responsible for the security of the whole data resource in an organization. LAN administrator will implement a fully functional security policy for database safety.Mar 2, Blog. Keeping your data flowing, and your business humming, requires a secure and reliable connectivity solution. A local area network LAN works well for a single location business.

However, as your business grows, expanding into new areas and new locations, connectivity becomes more challenging. A wide area network WAN can provide fast and secure communication between offices, even if they are located far away from each other.

Certain aspects of a WAN can be costly, but there are ways to trim those costs so that they are affordable. This article will discuss the pros and cons of wide area networks. Given the wide availability of Internet access solutions, some businesses use email and file sharing tools as their primary means of communication. Eventually, though, a successful business will likely require a more robust data network. That is where a WAN comes in. The data you send from the WAN is not viewable or accessible to anyone outside your own organization, like it could be if sent via the Internet.

Privacy and Security: As mentioned above, a WAN provides a direct, dedicated connection through which your data can pass. This limits opportunities for others to intercept your data as it is in transit between locations. The bottom line? WANs offer a distinct privacy and security advantage.

Network Performance Consistency: Equally important, your data does not have to compete with other Internet data for bandwidth as your communications travel between destinations. You get continuous access to all the bandwidth you are paying for. This allows your business to avoid throughput lags commonly experienced in the Internet. The consistent performance and enhanced security noted above create a network environment in which you can effectively incorporate telecommunication solutions, such as VoIP.

You therefore get the benefit of centralized management from a single dashboard for both your data network and telecommunications. For example, implementing a WAN will require investments in hardware, software, circuit costs, and testing.
