Which Connection is Best - Fiber, Copper, or Wireless?


Before knowing which connection is best for internet usage Fiber, Copper, or wireless, we need to know the connections available and their functionality in different environments. The connection that the user selects depends on the usage, cost, installation location, services needed from the internet, and speed of data transfer when uploading or downloading a file or large volumes like movies, software tools, applications, etc.

All types of internet connection depend on the bandwidth on how many units (represented by Mbps or Gbps per second) are used for streaming any live video or how frequently the user downloads or accesses cloud applications that are used with an internet connection. Issues may arise when many numbers of users login into the same application at the same time under the same network area, thereby increasing the bandwidth within a short time which reduces the speed of the connection for the day.

Types of Connections

Internet connections are provided to users placed on three mediums as Copper, Fiber Optic, and wireless. Let us discuss the specifications, functionalities, pros, and cons of each one in detail below

1. Copper

Copper cable has been invented during telephonic periods which use wires made of copper material to transmit data through the network. This allows a voice call via electric signals with less bandwidth provided to the user at the lowest cost.

Copper cable connection is best suited for rural areas within a limited distance range and connection speed varies from 300Mbps to 10Gbps.

2. Fiber Optic

Fiber optics transmit data over transparent material made of plastic or glass as light waves for larger-distance communication. This offers high speed, bandwidth, and reliable connection when compared with traditional copper cabling.

These cables are resistant to weather and collision as the data is transmitted as light waves which travel at a faster rate than electric signals. When multiple users need to connect to several devices at the same time then a fiber optic connection is preferred which provides faster upload and download features and live streaming without buffering.

This supports up to 60Tbps and beyond and also provides internet and telephone connection through the same modem or router for home and business environments.

Advantages of Fiber optics over Copper cables

  • Transmission rate − Comparison of photons and electrons are to be considered for the transmission rate. As said above, the speed of light (photons) travels faster than signals of the electric form (electrons). Signals lose their strength when traveling to longer distances, but photons do not fade their strength during transmission which increases the latency and bandwidth factors.

  • Cost − Installation of fiber optics is affordable in the local area network at a reasonable cost when the host servers already have built-in support with fiber cables and occupy minimum space compared to copper cables.

  • Reliability − Copper wires do not withstand severe climatic conditions, degradation, breakage, power fluctuations, moisture, corrosion, or rusting whereas fiber optic cables are capable of handling all these environmental conditions and provide reliable communication from one end to other.

  • Security − Copper cables produce electricity so when there is any damage in the cable then it cannot be detected which may lead to a short circuit or fire explosion and the connection fails whereas in fiber optic cable when there is breakage it can be monitored through power transmitted or pilot range.

3. Wireless connection

Wireless internet technology has reduced the cost of installing fiber or optic cables, the time consumed for authentication of user login credentials, etc.

This feature allows users to connect single or multiple devices from one source point to access an internet connection. The devices can be mobile phones, laptops, tablets, or any device that support the Wi-Fi option. Radio waves are used for providing data connectivity to devices.

Users can connect to 3G, 4G, and 5G services supported by their devices through wireless media at a flexible place wherever needed without the installation of any physical cables.

Wireless vs. Fiber Optic and Copper cable

  • In the case of Wireless, the speed of data transfer depends on the distance between the device and the host station located. When multiple devices or a single device are connected far away from the broadcast area then signals become weak which may result in lowering the speed of the upload/download or streaming process. But fiber optic can cover longer distances with high speed and bandwidth when traffic over the network is minimum.

  • Wireless connection is much cheaper as it does not require any installation cost to set up the connection.

  • Portability is the main reason why wireless connections are preferred over fiber optic or copper cables. Handsets or any internet-supported devices can work effectively as needed by the user at any time and anywhere.

  • Security will be a concern when wireless connections are used in the public network without authentication as the user may lose confidential data when a hacker intrudes over the network. But with fiber optic and copper cables, user credentials are verified beforehand inside the local area network which provides more security than wireless connections.

So, each of the connection types have its pros and cons as discussed above. Choosing the best option depends on the factors like cost, speed, bandwidth, security, reliability, portability, etc. Combining wireless and fiber optic is considered as best which supports most of the features useful for today’s technology and emerging devices.
