Linkem Unveiled: A Comprehensive Guide to How it Works

Linkem is a popular fixed wireless access (FWA) internet provider in Italy, offering an alternative to traditional broadband connections like DSL or fiber. It leverages radio waves to deliver internet service directly to your home or business. This guide dives deep into how Linkem works, providing a detailed understanding of its technology, installation process, and key components.

## What is Fixed Wireless Access (FWA)?

Before delving into the specifics of Linkem, it’s crucial to understand the underlying technology: Fixed Wireless Access (FWA). FWA uses radio waves to transmit internet signals from a base station (a central hub or tower) to a receiver located at your premises. Unlike mobile wireless, FWA connections are fixed – the receiver remains in a stationary location. This allows for a more stable and reliable connection compared to mobile broadband.

Think of it like this: a traditional wired internet connection (DSL, fiber) uses physical cables to transmit data. FWA, on the other hand, is like a long-range Wi-Fi connection specifically designed for delivering internet service.

**Advantages of FWA (Compared to Wired Connections):**

* **Faster Deployment:** FWA can be deployed much faster than wired infrastructure. Laying cables can be time-consuming and expensive, especially in rural or difficult-to-reach areas. FWA requires setting up base stations and installing receivers, a significantly quicker process.
* **Wider Coverage:** FWA can reach areas where laying cables is impractical or economically infeasible. This makes it an ideal solution for providing internet access to rural communities or areas with challenging terrain.
* **Cost-Effective:** In certain situations, FWA can be more cost-effective than deploying wired infrastructure, particularly in low-density areas.

**Disadvantages of FWA (Compared to Wired Connections):**

* **Susceptibility to Weather:** Radio wave signals can be affected by weather conditions such as heavy rain, snow, or fog. This can lead to temporary slowdowns or interruptions in service.
* **Line of Sight Issues:** FWA requires a clear line of sight between the base station and the receiver. Obstructions like trees, buildings, or hills can interfere with the signal and reduce performance.
* **Shared Bandwidth:** FWA bandwidth is often shared among multiple users in a given area. This means that speeds may fluctuate during peak usage times.
* **Latency:** Generally, the latency (delay) in FWA connections is higher than with fiber connections. This is due to the nature of radio wave transmission.

## How Linkem Works: A Step-by-Step Breakdown

Linkem operates as an FWA provider, utilizing radio waves to deliver internet service. Here’s a detailed breakdown of how it works:

**1. Network Infrastructure:**

* **Base Stations (Towers):** Linkem maintains a network of base stations strategically located throughout its service area. These base stations are equipped with antennas that transmit and receive radio wave signals.
* **High-Capacity Backhaul:** Each base station is connected to Linkem’s core network via a high-capacity backhaul connection, typically using fiber optic cables. This ensures that the base station has sufficient bandwidth to handle the internet traffic from its connected users.
* **Radio Frequencies:** Linkem uses specific radio frequencies authorized by regulatory bodies for its FWA service. The frequencies used can vary depending on the region and the available spectrum.

**2. Customer Equipment:**

* **Outdoor Unit (ODU):** This is the primary piece of equipment installed at your home or business. The ODU is a weatherproof antenna that receives the radio wave signal from the nearest Linkem base station. It’s typically installed on the roof, wall, or a pole, ensuring a clear line of sight to the base station.
* **Indoor Unit (IDU):** The ODU is connected to an Indoor Unit (IDU) inside your building via a cable. The IDU performs several crucial functions:
* **Signal Demodulation:** It demodulates the radio wave signal received from the ODU, converting it into a digital signal that can be used by your devices.
* **Router/Gateway Functionality:** The IDU often includes a built-in router, providing Wi-Fi connectivity and Ethernet ports for connecting your computers, smartphones, and other devices to the internet.
* **Power Supply:** It provides power to the ODU.

**3. The Connection Process (Step-by-Step):**

1. **Signal Transmission from Base Station:** The Linkem base station transmits a radio wave signal carrying internet data.
2. **Signal Reception by ODU:** The ODU, mounted at your location, receives this signal.
3. **Signal Transmission to IDU:** The ODU transmits the received signal to the IDU via a cable (usually Ethernet or coaxial).
4. **Signal Demodulation by IDU:** The IDU demodulates the signal, converting it into a digital format.
5. **Internet Access:** The IDU then acts as a router, providing internet access to your devices via Wi-Fi or Ethernet connection.
6. **Data Transmission Back to Base Station:** When you send data (e.g., browse a website, send an email), your device sends the data to the IDU. The IDU modulates this data into a radio wave signal and transmits it back to the ODU.
7. **Data Transmission to Base Station:** The ODU then transmits this signal back to the Linkem base station.
8. **Data Routing Through Linkem’s Network:** The base station forwards the data to Linkem’s core network and ultimately to the internet.
