How do you select a communication system for your network?

由人工智能和领英社区提供技术支持

Communication systems are essential for any network that involves data transmission and reception. They enable the exchange of information between different devices, such as computers, sensors, controllers, and actuators. However, choosing the right communication system for your network can be challenging, as there are many factors to consider, such as performance, reliability, cost, security, and compatibility. In this article, we will discuss some of the key steps and criteria to help you select a communication system for your network.

1 Identify your network requirements

The first step is to define your network requirements, such as the type, size, and topology of your network, the data rate and bandwidth you need, the distance and environment you operate in, and the power and budget constraints you have. These requirements will help you narrow down the possible communication systems that can meet your needs and expectations. For example, if you need a high-speed and reliable network for a large industrial plant, you might consider using a wired communication system, such as Ethernet or fiber optics. On the other hand, if you need a low-power and flexible network for a small home or office, you might opt for a wireless communication system, such as Wi-Fi or Bluetooth.

In many cases, it's important to consider what options you have to begin with. In some areas, you're stuck with a certain provider or network.

I think it helps to look at it as a network transformation: - Think about what services you need to add today, - Think what isn't working the way you need it should be today, - Then, think about what your expectations will be in 6 months, a year, and 2 years from now, - Identify which problems will be solved by adding the changes,

2 Compare different communication protocols

The next step is to compare different communication protocols that are compatible with your network requirements. Communication protocols are the rules and standards that govern how data is transmitted and received over a communication system. They define aspects such as the format, encoding, timing, error detection, and synchronization of data. Different communication protocols have different advantages and disadvantages, depending on the network requirements and applications. For example, TCP/IP is a widely used protocol for internet and web applications, as it ensures reliable and error-free data delivery. However, TCP/IP might not be suitable for real-time or time-sensitive applications, as it introduces delays and overheads. In that case, you might prefer a protocol that supports low-latency and deterministic data transmission, such as CAN or Modbus.

If looking at wireless: - is Wi-Fi good enough? - will LoRa work for some of those IoT functions? - if thinking about PLTE or P5G, is it worth the investment? - which priorities matter the most?

The choice among the many protocols depends on several factors including data transmission requirements, operational environment, power constraints, and the specific use case at hand. Understanding the particular needs of your project or network is crucial in selecting the most appropriate communication protocol.

3 Evaluate the performance and reliability of the communication system

The third step is to evaluate the performance and reliability of the communication system, based on the communication protocol and the physical medium. Performance and reliability are important factors that affect the quality and efficiency of your network. You should consider metrics such as data rate, bandwidth, latency, jitter, throughput, availability, and error rate. You should also test the communication system under different conditions and scenarios, such as varying traffic loads, interference sources, noise levels, and environmental factors. You should compare the performance and reliability of different communication systems and choose the one that best suits your network requirements and applications.

Look at where you are today, then ask yourself: - is the network performing up to your expectations? - what growth do you expect over the next 2 years? - will you expand or do you need more throughput? - what changes will make the biggest bang for the bucks?

4 Consider the cost and security of the communication system

The fourth step is to consider the cost and security of the communication system, as they are also crucial aspects that influence your network design and operation. Cost includes both the initial and operational costs of the communication system, such as the hardware, software, installation, maintenance, and upgrade costs. You should balance the cost and performance of the communication system and select the one that offers the best value for your network. Security includes both the physical and logical security of the communication system, such as the protection against unauthorized access, tampering, eavesdropping, and hacking. You should assess the security risks and threats of your network and choose the communication system that provides the appropriate level of security and encryption for your data.

- Do you have a growth and expansion budget? If so, is it enough? - How much will be broken out for security? - Did you remember to add staff or maintenance? - Did you remember to add OpEx as well as CapEx?

5 Implement and monitor the communication system

The final step is to implement and monitor the communication system, as it is an ongoing process that requires constant evaluation and improvement. You should follow the best practices and standards for installing and configuring the communication system, such as the wiring, grounding, shielding, and addressing of the devices. You should also use the appropriate tools and software for monitoring and troubleshooting the communication system, such as the network analyzers, oscilloscopes, and simulators. You should regularly check the performance and reliability of the communication system and identify any issues or faults that might affect your network. You should also update and upgrade the communication system as needed, to keep up with the changing network requirements and technologies.

Once implementing: - make sure the expectations are reached. You would rather have it overperform than underperform. - Did you test it to ensure reliability and security? - Now that you're testing it, is it what you expected? - how many "gotchas" did you experience?

Let’s Define Network First! If we are talking about your office network or organization’s network. We need to do the following: 1.choose the medium of transmission, for example fiber or copper. 2.Find out your bandwidth requirements. 3. Use softwares and hardware available by vendors like CommScope to monitor your network. One example is from CommScope called AIM solution.

The 1st thing is to find out if your client has already communications network in place. They are there for a reason like keeping conversations private, etc. you can propose a general grp chat like WhatsApp for quick communications.
