13 Things about Wireless Network you may not have known (WIFI)

READ 6 MIN

Simply put, a WIFI Network is a wireless router-based internet connection that is made available to a number of devices in a house or business. We look at things as a wireless network.

A Wi-Fi network: what is it?

• A WiFi network is just a wireless router in a home or business that distributes an internet connection to several devices. 
• Your internet modem is immediately connected to your router, which serves as a hub to distribute the internet signal to all of your Wi-Fi capable devices.
•  This allows you the freedom to continue using the internet as long as you’re in your network’s service region.

What does the acronym Wi-Fi mean?

• Surprisingly, it represents nothing. Although there is no such thing as wireless fidelity, Wi-Fi, also known as WiFi, wifi, wi-fi, or wi fi, is frequently considered to be short for that.
• A computer network that uses wireless data links between network nodes is referred to as a wireless network.

1. WiFi can be outdated compared to you:

In September 1990, a meeting was held to discuss the design of the invention that would become IEEE 802.11, subsequently marketed as WiFi. This was nearly 30 years ago.

2. Balancing of High Capacity Loads:

Network traffic is divided across several servers using a method called load balancing. By doing this, it is ensured that no server is overloaded. Load balancing enhances application responsiveness by distributing the work evenly. Additionally, it makes more websites and applications accessible to users.

3. Hawaii is the home of WiFi:

WiFi has a deep and fascinating History. A UHF wireless packet network called ALOHAnet was established in 1971 to link the Hawaiian Islands. Early predecessors of Ethernet and the IEEE 802.11 protocols, respectively, were ALOHAnet and the ALOHA protocol.

4. Scalable of Wifi Network:

The term “scale a network” refers to a network’s growth or expansion. Scalability, then, is the capacity of the network to scale or adapt to future growth. A network’s potential to develop or expand in size is constrained by its restricted scalability, to put it another way.

5. Management System for a Network:

• Hundreds or even thousands of access points, switches, firewalls, managed power, and other components may be found in modern wireless networks, which are far more sophisticated.
• A more clever method of centrally controlling the entire network is required. You have that ability and a whole lot more when you deploy a network management system.
• An enterprise network’s wired and wireless network devices are identified, set up, monitored, updated, and troubleshooted by an NMS.
• The performance data gathered from each network component is then shown by a system management control programme, enabling network engineers to make adjustments as necessary.

6. Many WiFi frequencies:

WiFi channels are subsets of frequency bands, which are bands of radio wave frequencies used to transfer data over the wireless spectrum. (Data transmission is faster and the signal range is shorter with higher frequency). The 2.4 GHz and 5 GHz WiFi frequency bands are portions of the wireless spectrum that are dedicated to transport WiFi.

7. Performance Measuring Capability:

• Bits per second are used to gauge wifi with internet speed. 
• 1,000 bits per second equal 1 Kbps (kilobits per second).
• A megabit per second (Mbps) is equal to one million bits per second. 
• A gigabit per second (Gbps) is equal to one billion bits per second.

Tools for Network Performance Monitoring:

• Nagios.
• Zabbix.
• Spiceworks.
• Icinga.

1. Unplug other gadgets to prevent interference:

1. Your Wireless Router should be placed far from other neighbouring routers, appliances, and solid building materials.
2. When not in use, unplug the electronics and appliances.
3. Do not use too many wireless devices at once or in close proximity to one another.
4. Try switching to a different wireless band or frequency (5GHz vs. 2.4GHz).
5. Take into account updating your wireless router, or at the absolute least the firmware (newer technologies and configurations can avoid the susceptibility of earlier solutions).

1. Control of Network Access in Wifi:

• Businesses can use network access control (NAC), a security programme, to regulate the kind and volume of access to their networks.
• NAC is the most suggested option to address the security issues of modern BYOD and IoT-filled network environments, according to WiFi engineers and IT security experts.
• The main advantages of network access control include better network performance, lower cyber threats, and increased network visibility.
• Therefore, network access control might be helpful whether you are concerned about your upcoming significant network security audit or IoT devices invading your network.

10.WiFi makes use of Radio Waves: 

• Data is converted to a radio signal via a wireless adaptor, which is then transmitted by an antenna. Your wireless router picks up those radio waves after they leave the antenna.
• A particular kind of electromagnetic signal called a radio wave is made to transmit data across comparatively large distances over the air.
• Amplitude, frequency, and phase components all exist in radio waves.
• To represent information, these qualities may change over time.

11. Role-Based Access Control:

• RBAC is a technique for controlling network access based on the roles of specific individuals inside an organization. RBAC guarantees that employees only have access to the information they require to do their duties and stops them from obtaining information that is irrelevant to them.
• Wi-Fi Cloud enables you to create custom role profiles and define access rules, including default Wi-Fi Cloud and custom vendor rules, or Google OU rules, to authorize wireless users. 

12. Redundancy:

• If the WiFi goes out, everything grinds to a halt. “Downtime” is a productivity and morale killer.
• Your unique environment and needs will determine the degree or quantity of redundancy your WiFi system needs.
• A spare tyre change is comparable to redundant wifi networks.
• For instance, a hospital setting will require more redundancy than, say, a coffee shop, but both must have a backup strategy in place at all times.

13. WiFi 802.11ac Access Points:

To meet the increased demand for reliable connectivity wherever users go, WiFi is always evolving. WiFi 5 Access Points (APs) can offer high client capacity and range with wifi speed up to 1.7Gbps per radio thanks to the current WiFi 5 standard (IEEE 802.11ac). Therefore, even in extremely demanding circumstances, WiFi 5 APs will safely deliver a pleasurable wifi experience.

Select WiFi 5 access points that are standalone or mesh-compatible. And if you require multi-packs, take advantage of our bundles to save money on installation. For your convenience and ease of monitoring, the broadbandbuyer range of WiFi 5 APs offers solutions for both indoor and outdoor use that are hosted locally or managed in the cloud.

Advantages of Wifi:

• mobility and adaptability.
• simple to install
• Network planning and adjusting is simple to do.
• Simple to find faults.
• simple to expand.

Disadvantages of Wifi:

• Efficiency:
• Radio waves are used in wireless local area networks to transmit data. Buildings, vehicles, trees, and other impediments may prevent the electromagnetic waves from travelling via wireless transmitters, which will have an impact on the network’s functionality.
• Speedy:
• The wireless channel has a substantially lower transmission rate than the wired channel. The 1Gbit/s maximum wireless LAN transmission rate is only appropriate for small-scale network applications and personal endpoints.
• Protection: 
• Since wireless communications are divergent and radio waves do not need to build a physical connecting channel, this is possible. Theoretically, it should be simple to observe any signal that is in the radio wave broadcast range, leading to communication information leakage.

Conclusion:

• In conclusion, individuals can anticipate worldwide wireless communications as technology develops. The world can become much more efficient thanks to the many advantages of wireless communications. 

• However, it does raise some issues, much like any other recent development in the modern world. A few problems that are preventing wireless technology from progressing include security concerns with regard to access to a person’s personal information or the perceived detrimental effects on society. 

The issues with wireless communications can be lessened and made to play a bigger role in the globe with more study and trials.
