In the late 1990’s, one of the first wireless standards was carried out. You may remember IEEE 802.11b – the first wireless LAN standard to be widely adopted and incorporated into computers and laptops. A few years later on came the IEEE 802.11g, which offered signal transmission over relatively short distances at speeds of up to 54 Mbps. Both standards operated in the unlicensed 2.4 GHz frequency range. In 2009, IEEE 802.11n (which operated in 2.4 GHz and 5 GHz frequency ranges) was a big step up. It provided anytime wireless access and was the de facto standard for mobile users.

Understanding wireless technology and standards like these is key to making sure you are investing in technology and equipment that can support your organisation’s short-term and long-term network-connection requirements. Wireless standards layout specific specifications that must be followed when hardware or software are designed related to those standards.

Now that we have covered the major wireless standards of the past, let’s look ahead at current standards – and what is yet to come.

General-Purpose Applications

Today’s wireless standards, like IEEE 802.11ac (Wave 1 and Wave 2), operate in the 5 GHz frequency range. This standard is used for many general-purpose, short-range, multi-user applications, like connecting end devices to networks.

As we have mentioned in previous blogs, IEEE 802.11ax is the “next big thing” in terms of wireless standards. As the successor to 802.11ac, 802.11ax operates in both the 2.4 GHz and 5 GHz frequency spectrums. It will offer 10G speeds, and the ability for multiple people to use one network simultaneously with fewer connectivity problems (and while still maintaining fast connection speeds). It will improve average throughput per user by a factor of at least four as compared to 802.11ac Wave 1.

High-Performance Applications

Operating at an unlicensed frequency of 60 GHz are IEEE 802.11ad and IEEE 802.11ay, which are used primarily for short-range, point-to-point applications vs. point-to-multipoint applications. 802.11ay is an update to 802.11ad, improving throughput and range. As compared to 802.11ad, 802.11ay can offer speeds between 20Gbps and 40Gbps, as well as an improved range.

IoT Applications

Operating at lower frequencies are standards like 802.11af (UHF/VHF) and 802.11ah (915 MHz). These standards are designed for extended-range applications, like connecting hundreds of remote Internet of Things (IoT) sensors and devices. They’re also used in rural areas.

Because they operate in lower-frequency ranges, they’re able to offer extended operational ranges. They can carry signals for miles, but have a low throughput of 350 Mbps.

Four New Types of Single-Pair Ethernet Cabling

For years, Ethernet cabling has used four twisted pairs to carry data without worrying about noise in data lines. Recent developments in IEEE 802.3 (Ethernet Working Group) and TIA TR-42(Telecommunications Cabling Systems Engineering Committee) has unveiled four standards projects which may change that; instead of four balanced twisted-pairs cabling, these standards feature a single balanced twisted-pair Ethernet cabling.

Of these four, one will impact enterprise networks the most. We will cover this standard first, and then explain the three other types of single-pair Ethernet cables below.

IoT 1 Gbps Applications: 100 m Reach

A 2017 Ericsson Mobility Report says that there will be nearly 28 billion connected devices in place globally by 2021 – and more than half of these will be related to Internet of Things (IoT).

With the ability to deliver data at speeds of up to 1G, and PoE power, this standard is intended specifically for IoT applications. Known as ANSI/TIA-568.5, it will provide cable, connector, cord, link and channel specifications for single-pair connectivity in enterprise networks.

This single-pair Ethernet cable may help network professionals connect more devices to their networks as the industry moves toward digital buildings – where all types of systems and devices integrate directly with the enterprise network to capture and communicate data.

Most of the devices used in digital buildings – such as sensors – have minimal power and bandwidth requirements (in applications like building automation and alarm systems). In these cases, single-pair Ethernet cable can provide a cost-effective cabling solution. The cable is smaller and lighter than a standard four-pair Ethernet cable, so it can also reduce pathway congestion.

The three other single-pair Ethernet cable types don’t apply directly to data centers or enterprise networks, but they’re still important to understand.
