A private LTE solution guarantees safety, exclusivity and optimal accessibility.

As a system integrator, Flash offers the most advanced solutions, looking beyond traditional voice and data communication systems. New technologies and systems are integrated to enhance the efficiency and security of the business processes. The geographical area in which the application must work and the exclusivity of the network are therefore essential. A private LTE in particular is an excellent solution when sensitive information is shared, process critical machine data is exchanged, and when there are many users on the network.

Robust Alternative to WiFi

A private LTE (pLTE) solution is particularly fitting in an environment where local data communication is necessary. It can be compared to a robust alternative of WiFi. A pLTE provides a reliable wireless IP connection between people and machines on a factory or port site or in a hospital or warehouse, for example.
Another option is a public LTE, via a mobile network operator, or via WiFi. After all, this also offers broadband connectivity. So why opt for a pLTE solution?

WiFi is, of course, an excellent technology, but it’s fairly easy for third parties to access, so security and accessibility are not always guaranteed. Moreover, the 2.4 GHz WiFi band is full in the Netherlands. Who hasn’t experienced the situation that your WiFi system at home is on the same frequency as the next-door neighbour’s and you have interference? This is an unwanted situation in an environment where connections are of vital importance.

Characteristics of private LTE system:

  • Robust independent network;
  • Business-sensitive information is protected against unauthorised access;
  • Less prone to interference than WiFi;
  • Exclusivity of users;
  • Secured data exchange;
  • Scalable model in case of expansion;
  • Coverage and business continuity guaranteed;
  • Voice network.

Private v Public Network

The reasons for opting for a pLTE solution over a public solution are numerous. Most importantly, a pLTE ensures that you are isolated from the public network and that your data also stays “inside” and cannot be accessed via an operator and/or the Internet.
Another reason is that the coverage of certain networks is not sufficiently reliable or that the user does not feel that the availability of these networks is sufficiently guaranteed. In a situation like this, a pLTE offers all the possibilities to decide where coverage is crucial and whether, for example, the system must be supplied with emergency power or redundant setup.
If coverage is the only issue that needs to be resolved, implementing a DAS (Distributed Antenna System) can also be a way to deal with this issue. DAS is a system in which linked antennas transmit the radio signals at locations where the radio signal normally does not penetrate.

Building Blocks

LTE, or as it is popularly known, 4G, is based on 3GPP standards. Within this standard it’s determined how the various network elements in an LTE solution work together. This makes it possible to compile a pLTE system for each customer with different building blocks. For example, you can choose brand A for the core (the heart of the system), brand B for the transmitters (called eNodes) inside the building and brand C for the eNodes outside the building. Combine this with the freedom to set up the pLTE system as it suits you best and you have a unique solution for setting up the right future-proof communication system. Flash sets up pLTE systems on the basis of a variety of brands such as Druid, Nokia, AirSpan and CommScope. (link to the products)

While it may look as if pLTE has no drawbacks, unfortunately that’s not the case. Granting licences is still under development. So for the time being, it seems that the most obvious course of action is to roll out pLTE systems based on the 1800 MHz frequency and to limit this to indoor solutions. There is a chance that others will use the same frequency band in the open field, which means there is a chance of interference.

What can we do for you?

Organisations with the highest standards of reliability, security and flexibility come to us for a customised solution. A pLTE system is an excellent tool for business and mission-critical communication; it allows for text messaging and calling (via an app), it is suitable for push-to-talk applications, emergency alarm solutions and for sharing image and sensor information, for example. With the right mix of applications, the communication needs of users in, for example, office and business premises, hospitals and warehouses can be fully met on the basis of a single universal and future-proof technology.
