Differences Between Tethering and Hotspot

Buzz

Tethering allows sharing the internet connection of one device with another. Windows, Android, and iOS have integrated features to enable tethering via USB, Bluetooth, and Wifi. When internet tethering is done via Wifi, it's also referred to as Mobile hotspot.

Before exploring the distinctions between Tethering and Hotspot, it's crucial to understand the meanings of these two connection types. According to the American Heritage® English dictionary, 'tether' is used to denote a rope, chain, strap, or cord for keeping an animal within a certain radius. In the context of mobile technology, connecting a mobile phone to a laptop via USB is called tethering.

Multimedia devices like Wifi, Bluetooth, or USB can utilize Tethering. Tethering allows sharing the internet connection of one device with another. All modern mobile operating systems have the capability for Internet connectivity.

Windows, Android, and iOS come with built-in features to enable tethering via USB, Bluetooth, and Wifi. When internet tethering is done via Wifi, it's also known as Mobile hotspot.

Tethering involves connecting your phone to a computer via USB cable to function as a USB modem.

Hotspot is the creation of a Wifi network, where the phone acts as a modem/router.

Approaching Tethering

Mobile hotspot is the most common approach for tethering. It's easy to set up, and with the presence of Wifi modules on most devices, Mobile hotspot doesn't require additional components.

Bluetooth Tethering is relatively challenging to set up and has lower speeds compared to Wifi. While Bluetooth tethering used to be popular, it's not widely used nowadays.

USB Tethering is fast and consumes minimal power as the device can be charged via USB. However, not many devices support USB tethering, and it may require special drivers or software on both ends along with some configuration tools.

Protocols and Connection Requirements

Tethering typically utilizes NAT (Network Address Translation) to share the internet. In this scenario, only the device connected to the Internet (the one shared) has a Public IP address. Other devices connected via tethering have Private IP addresses, and NAT is used to distinguish different devices on a single Public IP address.

Mobile hotspot provided by various telecom providers includes an adapter (Adapter) or a device enabling users to connect their computers to the internet anywhere.

Mobile hotspot is considered an alternative method to traditional ways of logging into a local computer network - LAN (Local Area Network) or other wireless networks from a laptop.

While various devices can use mobile hotspot, it's often associated with laptops. This is because laptops are versatile devices that can be taken anywhere but typically lack built-in mobile Wifi.

Beyond hardware, nowadays, software can also create hotspots. Programs like Connectify Virtual Router® and built-in tools in operating systems allow you to share the internet by 'turning' the Wifi module on your laptop or mobile phone into a virtual hotspot.

Provider Models for Tethering and Hotspot

Another fundamental difference in the provider model between Tethering and Hotspot is most telecom service providers offer mobile hotspots with a fixed-priced adapter, providing mobile hotspot services that require a monthly fee.

With tethering, the provider may include simple connecting cables to link a wireless mobile device to a laptop without a monthly fee. However, mobile hotspots seem more prevalent due to their convenience.

Cost Considerations

When opting for either of these services, you may want to consider related hidden costs. If using tethering to access the internet, you might have to pay for every kilobyte of data transferred over the mobile network. Regular internet usage could result in a substantial monthly payment on your mobile phone.

In comparison, with a traditional hotspot, you can use the internet freely without worrying about the amount of data you're accessing. The hotspot owner will pay a monthly service fee to the internet service provider.

Typically, mobile hotspots come without contracts and fees. Instead, you'll pay for the data you use and top up your card when necessary.

Providers with the best coverage and speed (such as Verizon Wireless) often come with expensive fees and may require a contract.

Connectivity Options

Wifi hotspots are found in both public and private locations. Nowadays, many public places worldwide, such as airports, shops, restaurants, hotels, hospitals, libraries, payphones, train stations, schools, and universities, have hotspots.

In addition to free internet access, users can also access commercial websites. Hotspots can be set up at home by connecting a wireless router to the internet via ADSL or 3G. This is the most common method used today to share internet connectivity at home with various devices.

Advantages of Mobile Hotspots over Tethering

Mobile hotspots offer several advantages over Tethering:

Bandwidth data: When tasks demand significant bandwidth consumption, you may find yourself in a situation of exceeding data transfer limits. Using a hotspot is one of the first choices in such scenarios.

Phone battery life: Using a hotspot means you never have to worry about battery capacity to get the job done. This comes with the benefit of longer and better battery performance.

Differences between Tethering and Hotspot in their ability to handle multiple devices: You can tether multiple devices. While you can tether multiple devices to your phone, the more you add, the speed tends to become 'worse.' Most hotspots, on the other hand, limit the number of devices you can connect, but you can connect more than one or two devices without performance issues.

Continuous operation: Tethering tends to reduce frequency, especially with prolonged usage. This is often attributed to firmware usage. Similarly, even with 'unlimited' data plans—depending on the service provider—limitations kick in after a certain period. Hotspots offer higher reliability as you incur usage fees.

Trade-off between data and voice: Service providers differ, but with Verizon Wireless and Sprint, tethering (via 3G, not LTE) conflicts with voice calls. While the phone may ring, data disconnects as soon as you answer and vice versa.

Diversify airlines: Travelers can often choose services from any airline providing better connectivity while on the move. Even when at home, you have the option to select the provider with the best performance.

Frequently Asked Questions

What is the primary difference between tethering and mobile hotspots?

The primary difference is that tethering shares an internet connection from a mobile device directly to another device via USB or Bluetooth, while a mobile hotspot creates a Wi-Fi network for multiple devices, allowing broader access.

What are the advantages of using mobile hotspots over tethering?

Mobile hotspots offer better battery life for your phone, the ability to connect multiple devices without significant speed loss, and often higher reliability during prolonged usage compared to tethering.

Can tethering be used with multiple devices simultaneously?

Yes, tethering can connect multiple devices, but performance may decline as more devices are added. In contrast, mobile hotspots maintain better speed for multiple connections.

What connectivity options are available for mobile hotspots?

Mobile hotspots can connect through Wi-Fi and are commonly found in public locations like airports, restaurants, and hotels. They can also be set up at home using a wireless router.

Are there any cost considerations when using tethering or mobile hotspots?

Yes, tethering may incur costs based on data transferred over the mobile network, while mobile hotspots typically come with fixed monthly service fees, allowing more predictable internet access costs.

How does the battery consumption differ between tethering and using hotspots?

Using a mobile hotspot generally conserves battery life on your phone, as it allows continuous operation without draining the phone's battery like tethering can during prolonged usage.
