How Wi-Fi Hotspots Work

Posted by Olayinka Alawode on

Wi-Fi hotspots provide you with an opportunity to conveniently access the Internet. At a time when there is a strong market affinity for portable technology, wireless connections ensure your devices are truly portable. You can seamlessly connect your smartphones, tablets, and laptops to a Wi-Fi network and simultaneously enjoy Internet service. 

The current setup is such that the majority of the people enjoying Wi-Fi do so from their home’s comfort or reside in big cities. Firms such as Nomad Internet are on a mission to ensure that the technology is widespread through rural Internet. As the technology matures, on the road, travelers can move around with their Wi-Fi hotspots using a Pocket Wi-Fi.

Read on to learn more about Wi-Fi hotspots and how they work.

What is Wi-Fi?

Wi-Fi is not an acronym but rather a full name. It refers to the wireless network created by equipment such as a router from which you can access the Internet. In the wireless network, communication takes a two-way path.

  1. Your device's wireless adapter converts data into radio signals which are sent via an antenna.
  2. Wireless router picks up these signals and begins the decoding process. The router passes over this information to the Internet.

Wi-Fi communication is based on radio signals, just like cell phones, walkie-talkies, and other devices do. However, it is slightly differentiated from other radios.

For instance, Wi-Fi travels at 2.4 GHz or 5 GHz frequencies, which is considerably higher than that of televisions, walkie-talkies, and cell phones. Also, it is based on the 802.11 networking standards that include: 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac.

The Wi-Fi hotspot created by a single router can be used to connect to multiple devices simultaneously. The devices just need to have wireless adapters. The connection made is virtually invisible, convenient, and fairly reliable.

How Wi-Fi works

When you connect to a Wi-Fi network to access the Internet, you are not connecting to the Internet directly but rather to a router. In turn, the router provides Internet access. If a router does not have a link to the Internet, you can still connect to the router by will not surf the Internet.

As opposed to transmitting information through Ethernet cables, Wi-Fi does so at various frequencies, typical ones being 2.4GHz. There are some niche settings that are used in certain situations. The frequency range creates numerous channels on which wireless devices send information back and forth, ensuring that the load is evenly spread. By doing this, no individual device experiences crowding of signals or interrupt others. However, when on a busy network, you may experience more of these interruptions.

Security of Wi-Fi hotspots

The security of a wireless connection depends on the type of Wi-Fi being connected to and access to the login credentials. Generally, you should not have security concerns with private Wi-Fi hotspots like prepaid hotspots and mobile hotspots. On the other hand, one cannot confidently guarantee that public Wi-Fi is secure. The provider of public Wi-Fi is in control of the mechanisms used to protect your data and privacy.

When connected to public Wi-Fi, you are advised to keep off activities that may compromise your data. Avoid conducting online shopping, banking, and similar activities. Public Wi-Fi is fine for checking mail on the web, social media, or general surfing.

Is Wi-Fi hotspot bad for your health?

You may have heard of claims that Wi-Fi is not good for your health. That is a concern that has attracted the attention of the research community. Numerous scientific studies on the topic confirm that Wi-Fi is not bad for your health.

The RF signals that Wi-Fi generates are legal and tested by the FCC to ensure they conform to the regulatory body’s threshold. Tests of these signals show that they are far below the hazardous exposure levels.

Generally, Wi-Fi frequencies lie in the 2.4 GHz and 5 GHz bands. Tests on exposure above these bands have not found any health risks. That implies you can use your home Wi-Fi with the peace of mind of knowing that your health is not at risk.

Conclusion

Wi-Fi hotspot provides a convenient way to access the Internet. The quality of service you get from this technology is determined by the equipment used and also by your ISP. Be sure to choose a reputable ISP such as Nomad Internet. Besides, regularly restart your router to maintain a faster connection.
