How to Centre Data Cabling Installation around Your Business’ Needs

Data Cabling Practices: A Stumbling Block for Office Buildings

In the office estate world, the traditional approach for data cable installation has been to lay out network cables based on a generic profile, often at the same time with electrical cables, both for efficiency and convenience.

Data cabling of this calibre is often sufficient for many London companies, whose networks only need to accommodate a few desktop computers, a single office printer, and users who perform light office work and rarely need video conferencing. However, as soon as these demands are exceeded, this traditional approach to data network cabling hits the limits of its potential.

Deploying a one-size-fits-all data network involves minimal design and is usually done based on best guess of what a customer’s network may look like. Sometimes the company doing the electrical installation will try to adhere to a standard that includes recommendations for data cabling installation, like TIA/EIA-568-B, and install a minimally-compliant structured cabling system, but this ultimately yields only modest short-term results.

Why does this approach fail for modern business networks? There are three major issues with it:

• The techniques and standards used for data cabling are quite different from those used for electrical wiring.
• The complexity, diversity and size of modern networks make it hard for data cabling that was deployed as an afterthought to electrical wiring to support your business’ operations.
• A network that can barely support current devices is unlikely to be able to cope with tomorrow’s demands – a vital threat to the well-being of any business.

Even though cabling is the least expensive component of a modern network, it is the physical foundation on which the network rests, and – like any foundation – it needs to be not only solid, but also adequate for the type of load that it supports.

Regulatory problems. Wiring regulations and standards, both for electrical and data wiring, are extremely complex and cover a great surface of issues, ranging from fire safety to electrical and optical signal integrity. Some of these issues, like avoiding tripping hazards, are common, but most of them are not. Some installation requirements and techniques are similar, but many (such as patching and terminating) differ significantly.

Treating one category of cabling as auxiliary to another often involves sacrificing some compliance. Since failure to adhere to electrical codes is usually more visible (and potentially more dangerous), many companies choose to sacrifice compliance with telecom and networking standards.

With some exceptions (mainly concerning H&S and private data protection), failure to adhere to data cabling standards will rarely result in legal trouble, but it does ultimately boil down to simply having a lower-quality network, with chronic performance issues that are difficult to troubleshoot. Link issues, insufficient or inadequate plugs, signal quality problems are common symptoms of improper data cabling installation, and their occurrence is difficult to predict.

Unfortunately, these problems surface only as the office equipment is being deployed and starts being regularly used. Some of them creep in slowly – badly installed cable sections, for instance, can work for a while before rapidly deteriorating.

Not only are these problems difficult to troubleshoot, but they are often dealt with using ad-hoc patches: you install additional switches in offices that have too few sockets, run cables to the sockets at the other end of the room to avoid the bad ones and so on. This results in mounting costs, trailing cables, and lengthy, costly troubleshooting.

One size no longer fits all. When it comes to data cabling installation, regulatory requirements give far greater elbow space to the designer than electrical cabling standards. This is done precisely because the industry has long recognized the greater need for case-by-case planning and installation.

Two traits of modern office networks have made proper data cabling installation even more relevant in the last seven years: increased reliance on wireless devices, and increasingly uniform high-traffic requirements.

Increased reliance on wireless devices means that it is no longer acceptable for an office to have one or two rooms where signal quality is good. Adequate Wi-Fi performance is expected everywhere. Wireless access points need to be deployed in the proper “hot” areas of the office, and the cables that connect them to the network switches need to be laid out through ceilings.

There is simply no way to do that without an RF survey and without prior knowledge of how your network is laid out. A best-guess approach, with access points installed wherever it was most convenient, or wherever the electrical cabling company happened to run data cables, results in poor Wi-Fi performance and non-uniform, inconvenient coverage. In our experience, this is the leading cause of the proverbial inconvenient Wi-Fi network, which barely has any signal and grinds to a halt in office areas, where everyone needs it, but runs great in the cafeteria and around the reception.

Modern office networks also require high speeds more uniformly than a few years ago: high-definition content for training videos, business calls and even the occasional YouTube video place higher strain throughout the network, not only on the backbone and server-room network.

Coping with these demands requires significant planning effort, because high-speed network performance depends on a great deal of parameters, such as cable type, length and even bend radius or proximity to electrical cables. More importantly, however, it requires specific installation techniques and, more often than not, special installation equipment.

Most electrical wiring companies only aim to offer basic data network installation services. Their target customers are businesses with basic networking demands that are unlikely to grow, such as those outlined in the beginning of this section. It makes sense for these companies to treat data cabling as an inconsequential expense that needs to be minimized, but this does not work for everyone.

Expansion and Emerging Technologies. These are, perhaps, the two most difficult points to deal with. Data cabling installation needs to reconcile two difficult demands: minimizing expenses, which requires using as little cabling and equipment as possible and the best price/capabilities ratio for current use, and dealing with long-term network growth, which requires spare equipment and cabling, and the most future-proof set of capabilities.

Meeting medium- and long-term expansion demands require, at a minimum, an awareness regarding these demands. Consequently, it can only be achieved if the long-term requirements of your business, your development plans for that particular office and the way they fit in your long-term vision are taken into account as early as the planning stage of the network.

A network that slows down or requires a great deal of maintenance as it grows may seem like little more than a nuisance, but with so much of modern business being conducted digitally, lack of scalability in your company network directly translates to lack of business scalability.

The risk is even greater when you begin to factor in emergent technologies. A recent Gartner report, for instance, recognizes that IoT “presents a myriad of opportunities for leading organizations to address their business issues”, and the same organisation predicts that business users will account for more than 7 billion deployments of IoT devices.

Furthermore, modern networks are not comprised solely of office computers. They integrate security and access control systems, building management endpoints and many other types of devices.

This radical growth in device numbers and diversity will be one of the leading causes of business data network growth, and you need to be prepared for it.

Data Cabling Installation and Design: A Business-Centered Approach

The problems outlined above are not necessarily new; in fact, dealing with network growth, both in terms of device number and diversity and in terms of traffic, has been a concern for the networking industry since the late 1980s. It is simply relatively recently that these problems have become more mainstream, as more and more businesses depend on high-speed network connectivity for their activity.

Addressing these problems and the risks they bring with them depends on recognizing two fundamental changes in the way we treat networks today:

• Networks no longer merely make day-to-day operations “more convenient”, but are an integral vehicle for day-to-day operations and, therefore, need to be designed and installed according to a business’ needs, not built by piling up equipment and running cables until day-to-day operations go well enough.
• Company networks connect a great deal of data sources and equipment, not only “typical” office equipment, and have greater performance and access control requirements.

These major trends have forced us to treat data cabling not as an external infrastructure element, one over which we have no control, but as an integral part of a business’ infrastructure, the same way we treat any other infrastructure-related asset, like servers and workstations.

What does this mean for data cabling installation?

First of all, it means that it is no longer done haphazardly or based on a “generic” customer profile – instead, it implements a specific network design that has been tailored to your business’ current and long-term needs. Second, it means that data cabling installation is often conducted separately from other building and/or furnishing efforts unless it has been integrated in the building plan. And, finally, that it needs to be carried out using specific installation techniques, respecting legal and industry requirements that are specific to data cabling.

A custom-made data cabling design and installation procedure does have higher upfront costs and it can take longer to implement. The cost of installing a generic data cabling (usually when the office building is erected) is supported by the developer and, while it is obviously “hidden” in the lease cost, it is typically much lower than that involved in customised data network.

The counter-argument that is most often invoked when discussing upfront cost is that the higher upfront price is compensated by the better performance and lower maintenance costs, as well as more easily amortized by the network’s increased performance. This is a valid point, but it hides an even more important point.

A well-designed data network cabling is not only a solid foundationtoday, but also keeps your business open to the possibilities of tomorrow. There is, for instance, a great deal of untapped potential in smart buildings, such assignificantly reduced energy bills and more efficient and flexible security systems.

In other words, being able to rely on high-quality data cabling is a competitive asset for your company – ensuring not only a solid foundation for day-to-day operations right now but also a competitive edge tomorrow.
