Why Consider 60GHz Technology?

Modern V-band 60GHz radios from CableFree are easy-to-deploy, cost-effective, wireless Gigabit Ethernet point-to-point bridges operating in the 60 GHz millimeter wave V-band, delivering full-duplex capacity of up to 1 Gbit/s over distances of up to 1km or more. Utilising Time Division Duplexing (TDD), the full 2.3Gbps capacity of the radio is available divided into both directions for transmit and receive under user control.

Combining carrier-class performance with advanced features such as adaptive modulation, multi-channel operation, low latency, high link throughput and security, the CableFree V-Band Radio supports a variety of shorthaul connectivity, network extension and backhaul applications.

Modern Chipsets for V-band wireless include 802.11ad wireless chipsets which offer high performance with compact, efficient & low-power solutions.

Technical Benefits of 60GHz Technology

  • Excellent “carrier class” performance for high-speed Gigabit capacity internet, data, and voice communications.
  • 60GHz radios have a small footprint making them perfect for metropolitan areas or aesthetically sensitive installations, such as in historic districts or architecturally regulated areas.
  • 60 GHz has unique characteristics which provide a high degree of immunity to interference from other radio signals.
  • Large 7 GHz channel size (“bigger pipe”), compared to conventional microwave solutions (typically 3.5 to 60 MHz).
  • “Oxygen absorption” attenuates 60 GHz signals such that they cannot travel far beyond their intended path, which (a) enhances signal/data security and (b) enables customers to install numerous 60 GHz radios in the same area (higher “frequency reuse”).
  • Excellent directivity via highly focused point-to-point antennas, perfect for building-to-building, tower-to-tower, and small cell deployments.
  • Up to “Five 9’s” (99.999%) availability, depending on rainfall rates/geographic location. In most parts of the world, rain attenuation can be compensated for by selecting the appropriate antenna and assessing link distance correctly, which is made easier by Choice of different 60 GHz antennas to suit precise applications

60GHz V-Band Wireless Technology

IEEE 802.11ad

Why Consider 60GHz V-band for Wireless?

60GHz (V-Band) is now becoming a popular frequency band in wireless world, with both short-range and wider area applications ahead for the tiny beams of this unlicensed millimeter radio technology.

60GHz V-Band Wireless

The frequency — part of the V-Band frequencies — is considered among the millimeter radio (mmWave) bands. Millimeter wave radios operate using frequencies from 30GHz to 300GHz. Until recently, 60GHz has typically been used for military communications as well as some commercial applications.

Major technology vendors show growing interest in the technology and the associated patents. Qualcomm Inc. (Nasdaq: QCOM) bought Wilocity recently to combine 60GHz WiGig technology with WiFi. Google (Nasdaq: GOOG) bought Alpental, a startup that, according to one of its founders, is using 60GHz to develop a “hyper scalable mmWave networking solution for dense urban nextGen 5G & WiFi.”

Why 60GHz, and why now? Here are a few reasons the market is expanding:

Drivers

WiGig:

A short-range wireless specification — using the Institute of Electrical and Electronics Engineers Inc. (IEEE) 802.11ad specification — that can link devices at up to 7 Gbit/s over a distance of up to 12 meters. That’s 10 times faster than the current 802.11n WiFi, though with less range. This makes the technology ideal for wirelessly delivering high-definition video in the home. The Wi-Fi Alliance has WiGig-certified products which started to arrive in 2015.

Wireless backhaul:

Particularly for small cells, operators can use the 60GHz radios to connect small cells to a fiber hub. (See More Startups Target Small-Cell Backhaul.)

Wireless bridges:

These are useful for providing extra capacity at events, ad-hoc networks, and private high-speed enterprise links.

Wireless Video:

Wireless video: Some startups have jumped the gun on the WiGig standard and plowed ahead with their own 60GHz video connectivity using the Sony-backed WirelessHD standard.

Point to Point, Point to Multipoint & Mesh Networks

60GHz is ideal for Point to Point (P2P, PTP) links as well as Point to Multipoint (P2MP, PTMP) and also Wireless Mesh Networks.

Why 60GHz?

A global unlicensed band exists at 57-64GHz. It is largely uncongested compared to the 2.5GHz and 5GHz public bands currently used for WiFi.

There’s also a lot of it. “The 60 GHz band boasts a wide spectrum of up to 9GHz that is typically divided into channels of roughly 2GHz each,” Intel Corp. (Nasdaq: INTC)’s LL Yang wrote in an article on the prospects for the wide-area and short-range use of the technology. Spectrum availability is “unmatched” by any of the lower-frequency bands.

The spectrum is now open and approved for use across much of the world. This includes the US, Europe, and much of Asia, including China.

As we’ve already seen, 60GHz technology is expected to offer blazing wireless transmission speeds.

Issues with 60GHz

No technology is ever perfect, right?

Transmissions at 60GHz have less range for a given transmit power than 5GHz WiFi, because of path loss as the electromagnetic wave moves through the air, and 60GHz transmissions can struggle to penetrate walls. There is also a substantial RF oxygen absorption peak in the 60GHz band, which gets more pronounced at ranges beyond 100 meters, as Agilent notes in a paper on the technology. Using a high-gain adaptive antenna array can help make up for some of these issues with using 60GHz for wider area applications.

Some vendors have also argued that there are potential advantages for the technology over omnidirectional systems. “The combined effects of O2 absorption and narrow beam spread result in high security, high frequency re-use, and low interference for 60GHz links,” one vendor notes
