Final Verdict:
The term WiFi is used commercially since early August 1999 with the assistance of a brand consulting firm that is called Interbrand Corporation. The partners (Alliance) hired Interbrand to find out a unique name of IEEE 802.11b by direct sequence. The world most renowned name Phil Belanger was a pioneer member (founding member) of the wifi alliance who finalizes the name of Wi-Fi instead of Interbrand invented the name of Hifi (Hi-Fi) and also created the Wifi icon or wifi symbol.
The Yin-Yang introduced wifi emoji and indicates the certification for interoperability of a product. Non-Wi-Fi Spectrum technologies deliberated for pinpoints such as fixed wireless. The alternative of wireless technologies inducted in mobile cell phones standards like 1G, 2G, 3G, 4G, LTE, and upcoming 5G has been introduced in the world as a competitor of WiFi.
Wifi Manager:
Cordless Manager is a network management tool by using this tool to tie your electronic devices or Android devices with internet. There are several sorts of wifi manager apps available on Google Play store paid and most are free of cost like wifi manager premium, esp8266 wifi manager and different companies or developers offer free wireless manager.

Wifi Frequency: wireless radio waves operating frequency refers to the waves for transmission. Frequency usually increases the strength of signals and minimize the as per FRIIS Transmission equation. The strength of the received signal depends on the transferring power. The Wi-Fi channels power of IEEE802.11b is 10mw-10dBm. This quantity of power is easy to handle through the wall.
When we think about the Bluetooth frequency channel power (transmit power) Min 1mw to Max 0dBm. It covers short distance and is not able to operate by the wall. In this case, the wifi antenna plays a vital role in reception through the walls.
Wifi IP Address: The definition of IP Address refers a unique sequence of numbers which are separated by full stops that represent or identifies every computer is using the internet protocol (IP) to communicate or transfer the data on the network. We can know the exact location and see the complete information of the sender through IP address lookup or IP address tracker (IP Address Locator).
Wifi MAC Address: Media Access Control Address consists of 12 unique characters like 0a:5b:00: ab: cd: oX e.g for each specific hardware and device. Mac address is necessary for internet support and also for other cordless connected support devices.
Wifi Map: This is special software that permits the users with passwords to bind any hotspot in their area search. Certified Wifi Map software fastens the devices through a global positioning system (GPS) and shows all possible Wi-Fi hotspots available. The users can lash their require hotspots device with spectrum wifi map password.
Wifi Repeater: A wifi repeater or wifi extender is a solution that is used to expand the coverage area of you the fei network. Its works by existing wifi signals receiving service, boosting the channel signal speed and amplifying.
Wifi Password: Wifi Password refers to protect the wireless network to the security key. Network security key or password is used to verify with your home network device. For a secure connection, key plays a vital role with your wireless router that works and allows you to get access on the bases of the authorized password. There are two security methods WPA (Wifi Protected Access) &WPA2. Fay Protected Access 2 is a security method which is added to Wai fi Protected Access (WPA) for a wireless network that key purpose is to provide stronger data protection with better network access control service.
How to change spectrum wifi password?
There are two versions of Pi Protected Access 2, 1st is WPA2 Personal and the second one is WPA2 Enterprise. WPA2-Personal: security method protects from unauthorized users access on the network by using of set-up password. WPA2- Enterprise: it is identified and verifies the network users from a server because Vi-fi Protected Access2 is compatible with broadband connection Protected Access.

Difference between Wifi and Internet:
The internet is a huge network setup made by tons of smaller local networks. Wideband connection Router gives your devices access to the internet network. Without a router you cannot be connected with this network but can use only local network hitch without internet access.
For instance, a local network could be included your router, your virtual systems, your cable less printers, wifi transfer file best option, where you can send any type of files like MS Word, MS Excel file, PPT file or PPT Format file, PDF file to the printers Form computers by the using of Wi-Fi connection without internet access.
Difference between Wifi Modem and Wifi Router:
Modem and Routers are most commonly used as external devices alliance for computers and other gadgets. Before describing the difference between both modem and router wi-fi, let’s short define the meaning of every component to better understand the difference. LAN is usually known as Local Area Network (Home Network/Office Network) and WAN refers Wide Area Network / Internet connection service alliance. How do they work?
There are 4 basic average network devices Modem, Router, Wireless Access Point (Wi-Fi /WAP) and Switch/Hub for networking. Let’s overview in brief:
Wi-Fi Modem:
The modem is the abbreviation of MO-Modulator, DEM- Demodulator which is used to fetter to an internet security protocol (ISP) by different types of transport mediums like the bridge.
It can be strapped with one virtual machine by using the Ethernet port. The modem can work without any router extension for transferring information like internet access for a single computer. A modem is also allowing connecting internet for access by providing a connection to the internet for sending and receiving data from using telephone lines. But, the drawback of this modem is not secure as per security perspective.
These transport sources could include of
- Dial-Up or xDSL (Phone Line),
- Cable Internet (Coax),
- Satellite, WiMax, 2G-LTE, 3G, 4G,
- FiOS (Fiber Optic System),
These sorts of modems have an input to subjoin the line from RJ-11 for a phone line, F-type cable for internet (ISP).
Wifi Router:
The router is a gateway between WAN and LAN that provides Network Address Translation (NAT), Firewall security. Wideband connection Router allows multiple devices and computers access through its own Local internet Protocol (Local IP) with signal sharing Wide area network IP from ISP. Most of the routers are usually built in dynamic host configuration protocol (DHCP) server. DHCP allows Dynamic IP Addresses to other devices to cement to the network.
- It can be connected to multiple computers or electronic devices through Ethernet or Wi-Fi.
- Routers can also share data and information between the different computers as a group or from personal IP. But it can’t peg to the internet without a modem.
- It can also manage the data in a network and transfer the specific date between home networks.
- It also provides security to protect or save the network.
Wireless Access Point:
WAP get information that is coming in shape of signal either wired or wireless connection and broadcasts by using one of the wireless protocols.
Hub or Switch:
In this case switch or hub gathers information from different computers and router. After the collection of the information, it transfers or distributes the information to all other computers or router via specifically given IP addresses of different computers.
Key Difference between Wi-Fi Modem and Wi-Fi Router:
Wireless Modems is usually controlled by ISP that provides you one box solution to wire-free internet by using the modem. Router, WAP, and switch are included in one unit that makes setup easier and you don’t do anything for hotspots sharing.
Wireless Modem: Router Wireless AP+ if LAN Wired Port (Switch) + Modem
Wireless Router doesn’t have a modem; it has only a broadband port, internet port, WAN Port. You can use a modem, in which router, switch, and WAP are already included.
Wireless Router: Wireless AP+ Switch+ Router
Wired Router: Witch+ Router
What is Wifi Calling? How Wifi Calling Works?
Term Wi-Fi Calling is a technology that allows smartphones users to receive and make calls without wire internet connection by a specific mobile connection. Now a day, wifi calling has become most popular due to facilitating voice and video calls. It also provides the opportunity of text messages sending and receiving by the user of higher data wifi speed rather than other cellular companies’ connections.
The wireless technology transmits the mobile messaging packets of a cell phone call or text form messages from smartphones over the internet wireless network and sends to the percipient receiver.
What Wifi Channel is best? How Does It Work?
Wifi Channel Band Definition:
There are two types of frequency channel bands for wifi 2.4 GigaHertz (GHz) and 5 GHz (Giga Hertz). As well as band concern, newer routers are usually known as “N Router”, this type of router has multiple band capabilities by using double or dual even triple bands. N router maximum capability of speed is up to 600 Mbps which has much faster speed rather than 802.11g models. 802.11ad is known as WiGig router which has maximum speed up to 8 Gbps that can operate in the higher level of the 60GHz band. This router has established a remarkable name in the internet market.
The older router channel band support the slower G specification at 2.4Giga Hertz band and the new model router AC or N router devices are the faster speed at 5 Giga Hertz per second (Gbps).
2.4 GigaHertz or B /G /N Band:
The 2.4GHz band supports all types of wifi bandwidth devices for hotspot sharing like laptop, tablet, and phones. 1,6 and 11 channels are non-overlapping channels, the meaning is that if other wifi networks are operating at channel 6 and your wireless network device is operating 1 or 11 channels then the other operating network will not interfere in your device channel because of 2.4 GHz support all these channels. In some case, if channels 2,3,4,5 are making interference they affect channel 1 and 6, if channels 7-10 are making interference then these will affect channels 6 and 11 with based on the info from wifi analyzer or insider. So, you have to choose your channel from 11, 1, and 6 only, the main reason is there are very low numbers of co-channel users to other cordless networks for hotspot.
5 GigaHertz or AC /A /N Band:
New model wifi devices support 5GHz frequency band but old devices will not support this band. The 5GHz channels by design are non-overlapping because they don’t have any intermediate channels like in the case of 2.4 GHz channel networks that affect your network. The 5GHz band has many sub bands which is called the UNII bands. These channel numbers have 4 differences subsequent and start from 36. The first number is 36,40,44,48,52,56,60 etc…; this sequence rule doesn’t apply to UNII-2e band which has military radars and weather radars interference.
Limitations: UN11-2e and UNII-2 refer to DFS Channels because the same frequency is using in radars. 52 Operating Channel represents UNII-2 band that is representing for solder WAP router (Wifi access point) should need to leave this channel and choose any other channel of the operating network. This rule is applied by the almost all cable-free router providers. If your router is operating any DFS channel frequency band network then your wifi device would not be suitable for proper work. Because The Wifi channel scanner gathers basic information based from wifi analyzer who selects a telecommunication channel width mostly from UNII-3 OR UNNI-1 because it has the lowest number of other sub band networks.
