How does LTE bonding actually work?

What is LTE bonding and what is the difference to normal LTE/5G?

Thanks to their widespread use, mobile connections are an ideal way to establish a data connection on the move or temporarily in one place. Unfortunately, however, this type of connection is also subject to technical disadvantages. This can become a problem when used at events. With LTE bonding, not only can these disadvantages be eliminated, but significantly faster bandwidths can also be achieved.

In the mobile sector, our LTE bonding enables the seamless merging of multiple connections to achieve a stronger and more reliable internet connection. This technology is particularly valuable to us in the event and industrial sectors, where we work with our customers to ensure a reliable and fast connection. This allows us to offer customized solutions that meet the individual requirements of each project.

But how does LTE bonding actually work?

The bonding server: The heart of LTE bonding

The bonding server is the heart of our LTE bonding and plays a crucial role in combining multiple mobile connections.

Functionality and significance

The bonding server acts as a central node that receives the data packets from several mobile connections and combines them efficiently. It ensures that the data packets are sent to the recipient in the correct order, thus ensuring a stable and reliable connection. The bonding server also manages the connections and monitors network availability. Thanks to the use of a bonding server, we can offer greater reliability and stability than conventional mobile connections. So you can be sure that your data is always transmitted correctly and quickly, regardless of how many connections are used.

Advantages of LTE bonding

The LTE bonding solution offers a variety of benefits that make it an attractive option for companies and organizations that depend on a reliable and fast Internet connection.

Efficiency and speed

With LTE bonding, we combine several mobile connections into a single, strong connection. This leads to a significant increase in data transmission speed and improved efficiency in the use of internet resources. By bonding multiple connections, we can also reduce latency, which is particularly beneficial for applications such as live streaming and online gaming. In this way, we ensure that your live streams run smoothly and without interruptions.

Reliability and stability

Another major advantage of our LTE bonding is the increased reliability and stability compared to conventional mobile connections. By combining multiple connections, we can maintain a stable connection even in the event of outages or fluctuations in network availability. This is particularly important for companies and organizations that depend on a reliable internet connection. With our LTE bonding, you can be sure that your connection will remain stable even if one of the connections fails.

The disadvantages of LTE connections

You're probably familiar with this. You've just had good LTE reception and suddenly the connection is agonizingly slow. This is because you have to share the available bandwidth on a mobile phone mast with all the other connected devices. So if very few devices are connected to a particular mast on one day, the mobile connection is very fast. However, if there are a lot of devices connected to this mast on another day, you will suddenly be surfing much more slowly at the same location. This makes it clear where the biggest problem with an LTE connection lies: You can't rely on it. Even if you notice a good connection today, it can look completely different tomorrow. This is particularly relevant for events. Because when the guests arrive, there may suddenly be no data connection at all because too many devices are connecting to the next mast at the same time.

Our solution - stable and redundant LTE reception:

To prevent this, we are using our multi-LTE case we rely on three parallel connections to different providers (Vodafone, Telekom and O2). In the data center, the signals are combined into a synchronous output signal using LTE bonding . If there are now fluctuations or even a failure of one provider, this can be compensated for by the remaining connections. And if all the cell phone towers on site are overloaded or mobile communications are not developed at the respective location, we can even use directional radio to target towers further away and thus simply skip an overloaded tower.

The challenge with multiple connections

In data connections, the data is always divided into small packets, which are then sent one after the other. If the packets arrive in the wrong order or incomplete, the receiver can no longer process the information sent. File transfers fail and video streams experience dropouts and interference. This is usually not a problem when transmitting over a single connection, as the packets always arrive in the order in which they were sent. Completeness can be ensured by the transmission protocol.

 

If several connections are used in parallel, a number of problems arise. This is because the individual connections have different transmission speeds and response times (latencies). If the packets to be sent are split across several connections, it is possible that a packet that is sent later will still reach the recipient earlier. The result is chaos on the receiving end, which manifests itself in disruptions and an overall unstable connection. A bonding server acts as a central remote station that sorts the data packets and sends them to the recipient in the correct order, enabling fail-safe live transmission.

In addition, many websites and other services that require you to log in only allow one session per connection. If you receive such a service packets from different connections at the same time, the session is terminated for security reasons. As a user, you will notice this when you are constantly logged out.

Our solution:

With our multi-LTE/5G case, we do not send the data via the various connections directly to the recipient, but first to a so-called bonding server. This server sorts all packets back into the correct order and then sends them to the recipient. All packets arrive at the recipient in the correct order via a single connection. This allows multiple connections to be used for the benefit of fail-safe and faster transmission - without the problems normally associated with this.

 

Incidentally, the bonding principle can be combined not only with LTE signals, but also with normal DSL connections. This means that the multi-LTE case can also be used as a high-availability solution in office or event locations. If the regular Internet fails, one of the other connections is automatically used. These can be LTE or satellite connections.
