If, Computer network do not need any types of cable for making connection in between multiple network nodes like as laptop, PC, phone, and more. So, it is known as “Wireless Network”, because, they mostly makes use of Radio Frequency (RF) connections between nodes in the network.
Advantages of Wireless Network
There are various benefits of wireless network over wired network; below mention all.
Less Expenditure: Due to wireless network, it does not need any physical wire for set up. So it helps to reduce the expenditure to copper wiring for small range networks.
Better Mobility: Wireless networks allow to users for getting to access real time information, so they can roam near your company’s area without getting any disturbance from the network. This better mobility enhances the teamwork as well as productivity.
Cost Effective: This network is cost effective solution because it allows to easy and affordable configuration. Wireless network is best option for those sites where owners do not permit any wire installation.
Scalability: Wireless network allows to connect number of network devices without any extra wire set up.
Flexibility: If, you want to change your network in the future, so wireless network is best solution for easily update any time with to meet new configurations. Office based employees can use wireless networks without sitting at the dedicated computer systems.
Accessibility: Wireless network provides the best accessibility because it doesn’t need any wire or cable for installation. So all users are able to access network while moving, and you can get access to this network without using any additional cables and adapters.
Adaptability: Wireless network has great adaptability because it is easy to change needs than wired networks, because technology enables extra possibilities.
Guest Access: It allows to secure network access to guest users like as your clients and business partners.
Improved Efficiency: It offers the better and improved data communication that leads to higher transfer rate of information in between the customers and partners within the business. For instance, salespeople can check rates and stock levels while making sale calls.
Increased Opportunities: With using of wireless network, users can avail new products and services in the market like as several cafes, airport lounges, train stations, hotels have installed WIFI services to allow mobile visitors for connecting their devices.
Disadvantages of Wireless Network
There are several challenges of wireless network; below explain each one –
Less Security: Wireless networks broadcast all data over air, so there is most of chance of data leakage, data modification, and data may be intercepted by unauthorized users. So, in wireless network, data encryption must be done at the higher level.
Low Speed: Wireless network has less transmission speeds of data compare to wired network. Mostly, wireless network’s speed is typically 1-54 Mbps rather than wired network100Mbps and up to many Gbps.
Coverage Area: Mostly, wireless networks have less communication range. If, any time you want to enhance the range of communication then you must be invest extra expenditure for wireless Point or repeaters.
Wireless network is getting more challenges in some site like as building, because some buildings have “Black Spots”, and due to those black spots WIFI signals get weak.
Less Reliability: Wireless network are less reliable compare to wired network. Many users are using wireless network in the same site means building, so due to this, it can get interference. So it can output in worst communication or entire damage of communication.
Health Problem: Wireless networks transmit signals (Radio waves or Microwave frequencies) in the air, and these waves are more harmful for human body. Some health issues can be arisen like as cancer, insomnia and apoptosis. Wi-Fi signals are more dangerous to pregnant ladies because it produces Electromagnetic radiations.
Less Bandwidth: Several routers permit 30 maximum network devices to be linked. If, you try to add extra devices to network then its bandwidth gets weak.
