Difference Between Public and Private Network

Difference Between Public and Private Network

This is high time for us to understand the difference between public and private network. The term “wireless networking” implies universal connectivity. Still, we have yet to see this in today’s industrial and business-critical domains, such as manufacturing, supply chain management, and transportation energy and systems.

Instead, we see a disjointed picture, a landscape teeming with proprietary device networks, users, and buyers, as well as broken promises regarding the wireless technologies’ potential, amidst all this commotion and a new generation of wireless communications and clutter. It has emerged as a solution for challenging environments.

Private LTE networking technology—Public network based on LTE technology for local and autonomous networks—allows users and customers to integrate various sensors, machines, people, vehicles, and other objects from multiple sources.

What Is a Public Network?

In simple terms, a public network is a network, wireless or wired, that computers and devices you don’t trust are connected to. A public network is a network to which everyone, i.e. the general public, has access and may link to other networks or the internet.  Because a public network has little or no limitations, users should be cautious of potential security concerns while connecting to it—a public network in a good term, not a topology or any technically relevant concept.

Except for the security, addressing, and authentication methods, there is no technological difference between a private and public network in hardware and architecture.  Any user may connect to a public network, its security must be increased, and different anti-threat and malicious act procedures must be implemented. Because anybody may relate to the network, malevolent people may attempt to compromise the systems of unwitting users.

Many corporate secrets have been taken from executives when using their laptops at coffee shops with accessible public networks. Even file sharing over a public network is generally considered dangerous because the files can be malicious and because your system is somewhat open and more accessible when it is visible on the network to everyone else.

What is a private LTE network?

A private LTE network is any connection within a specified network wherein restrictions are established to promote a secured environment. This form of the network may be set such that devices outside the network are unable to access it. Depending on the settings encoded in network routers and access points, only a specific set of devices may access this form of network.

Private networks comprise the majority of corporate, industrial, and government Blockchain projects. In private networks, users are known, have login credentials issued by a trusted authority, and are likely assigned to a specific limited scope of activities on the network. Private networks are preferred in businesses and private organizations because they provide high security for sensitive data. To have a secure connection, some issues must be addressed, making private networks more challenging to set up.

The first consideration is the number of people or devices that can connect. Next, Web servers must be safeguarded since their visibility to the Internet makes them vulnerable to harmful assaults. Finally, high-security hardware and software, such as firewalls, must be implemented since they may significantly aid in making the network private and secure. Private networks are preferable and secured compared to security and sustainability issues.

Difference between public and private networks

Private LTE network arrives with a lot of potential in terms of allowing new, creative use cases that will provide enormous value to firms in many areas such as manufacturing, mining, logistics, and so on. However, private LTE is already meeting the demands of an increasing number of businesses, and many others are questioning the need to go beyond public networks and into private networking.

A public network is still widely used across diverse industries by organizations of all sizes, as proven by the latest study and survey with over 200+ enterprises internationally in essential sectors. Whether public network, industrial ethernet, or private 5G, each connection has its own set of features tailored to specific use cases.

Let’s look at how private LTE compares to public networks in various ways.

Speed

Private 5G is far and away from the quickest, with LTE being somewhat slower but still competitive with public networks.

Latency

Private 5G has the lowest latency at a few milliseconds, followed by LTE with a round-trip delay of 30 milliseconds, and finally, private network with the worst latency of the three up to 500 milliseconds.

Interference & Congestion

The public network operates on an open, shared, unlicensed spectrum that is frequently congested and subject to signal interference. Private LTE and 5G require centralized orchestration of spectrum assignments between networks to avoid interference.

Coverage

The private network is typically short-range, with a range of up to 5K sqft per radio. Public networks use higher power levels outdoors and lower data speeds at the cell edge to cover big spaces and outdoor situations – up to 25K sqft indoors and 1M sqft outdoors – with a private LTE access point.

The public network was never intended to span long distances; extra access points, repeaters, and bridges have all been proposed as potential solutions to compensate for the lack of coverage.

Security

The private network operates on an open spectrum, which hackers regularly exploit. The ability to offer network access without needing authentication or encryption has always prompted business IT professionals to take extra precautions in safeguarding Wi-Fi airwaves and equipment. Private LTE and 5G networks are just that. To allow network access for a given device, they require an approved SIM card, and centralized communication encryption is always enabled.

Which is a safer, public or private network?

Public networks increase the chances of being hacked like so many attacks can be performed on your device on such networks. Some of these attacks might be harmless, and you may never notice they ever happened, while others are so serious that they may lead to loss of sensitive data or even wreck your device.

Some of the sensitive information that attackers look for include financial information, bank account logins, and sensitive financial information on corporations. Malware distribution is another common security threat associated with public networks. Malware refers to malicious programs that perform tasks specified by an attacker installed on your schedule.

On the other hand, you can secure connections to protect traffic that flows between controlled and trusted endpoints by using the private network. Private networks make your business and workplace safer by using and limiting known users and endpoints. A personal network connection can encrypt data while it travels over networks.
