Upgrade your Infinet 5GHz Radio Links

How to Upgrade your Infinet Radio Links

Infinet Radio Links 5GHz unlicensed

Why upgrade your Infinet Radio link?

Infinet have announced to partners that due to the geopolitical issue between Russia and Ukraine that Infinet exports will cease and concentrate on the domestic market only, therefore cannot supply overseas customers for their entire range of radio links.   It’s always sad to see a long established vendor exit global markets, and this move means many radio link users will have to look for alternatives.
Many users own radio links which are older and sometimes problematic.  Often, users require higher reliability, uptime, capacity or distance than their older radio links can provide.

The Need for Reliability and High Availability

Modern IP networks demand higher capacity and uptime, and as radio links are installed outdoors often in harsh conditions where they age faster than indoor mounted IT equipment such as switches and routers, which are installed in nice airconditioned environments.   Modern Carrier Class wireless equipment is designed for all-outdoor use including harsh environments and can ensure ultra-high availability and reliability in practical use.

Alternatives to Infinet and 5GHz radios

There are many alternatives available including Carrier Class radio from other vendors, radio links with 10Gbps+ capacity, Microwave links and MMW radio.  These have different characteristics, capabilities and price points.  Modern links can offer up to 40Gbps capacity and for low-end solutions, MIMO radios at lower price points than high cost MIMO radio for sites where budgets are tight.

If the customer requires a direct replacement radio link, there are some trusted MIMO radio vendors currently available with reliable shipping products.

Other radio vendors currently offering carrier grade radio:

What is DDM and DOM used in Optical SFP/SFP+ Transceivers?

What is DDM (Digital Diagnostic Monitoring)?

DDM or Digital Diagnostic Monitoring is a management technology which allows operators to monitor several parameters of a fibre optic transceiver, such as optical input/output levels, temperature, laser bias current and supply voltage. All of these parameters can be monitored in real-time.

Examples of optical modules supporting DDM are the Small Form Factor Pluggable modules such as SFP and SFP+ for 1Gbps to 10Gbps and up to 25Gbps capacity

SFP / SFP+ Optical Module with DDM / DOM Monitoring features
SFP module with DDM / DOM Feature

What does the DDM do exactly?

DDM is capable of providing component monitoring on transceiver applications in great detail. The system that is used is an extension of the interface defined in GBIC specification (GBIC being a type of transceiver).

The interface itself is capable of generating alarms and warning flags which alert the host system when operating parameters fall outside of a set of ‘normal operating’ rules. This allows the end user to isolate faults and predict failure.

What is DOM?

DOM or Digital Optical Monitoring is used to monitor certain parameters of an optical transceiver in real-time. This helps operators to identify the location of a fiber link failure which in turn helps to simplify the maintenance process and improve overall system reliability.

DOM gives you the ability to monitor the transmit and receive power of the optical transceiver module, its temperature and supply voltage. Each system can be configured to monitor transceivers that are in operation either globally or by specific port.

With DOM console message and syslog messages are sent if operation falls below or rise above the specific transceivers manufacturer thresholds.

Most modern transceivers support DOM functions.

When building a Wireless Network Key parameters include:

  • Channel Allocation
  • Spectral Shape and Mask
  • Packet Information
  • Data rates
  • Modulation types
  • Transmitter Measurements
  • Channel and Centre Frequency

What is Wi-Fi 6? Wi-Fi 5? Wi-Fi 4?

Under its naming convention, the WiFi alliance calls 802.11ax Wi-Fi 6. 802.11ac is now WiFi 5, and 802.11n is WiFi 4. The idea, according to the WiFi Alliance, is to make matching endpoint and router capabilities a simpler matter for the rank-and-file user of WiFi technology.

Meanwhile it’s important to know that the Wi-Fi Alliance has not made up simpler names for all the 802.11 standards, so it’s important to be familiar with the traditional designations. Also, the IEEE, which continues to work on newer versions of 802.11, has not adopted these new names, so trying to track down details about them using the new names will make the task more complicated.

802.11b

Released in September 1999, it’s most likely that your first home router was 802.11b, which operates in the 2.4GHz frequency and provides a data rate up to 11 Mbps. Interestingly, 802.11a products hit the market before 802.11a, which was approved at the same time but didn’t hit the market until later.

802.11a

The first following the June 1997 approval of the 802.11 standard, this standard provided operation in the 5GHz frequency, with data rates up to 54Mbps. Counterintuitively, 802.11a came out later than 802.11b, causing some confusion in the marketplace because customers expected that the standard with the “b” at the end would be backward compatible with the one with the “a” at the end.

802.11g

Approved in June 2003, 802.11g is the successor to 802.11b, able to achieve up to 54Mbps rates in the 2.4GHz band, matching 802.11a speed but within the lower frequency range.

802.11n (WiFi 4)

The first WiFi standard to specify MIMO, 802.11n was approved in October 2009 and allows for usage in two frequencies – 2.4GHz and 5GHz, with speeds up to 600Mbps. When you hear the term “dual-band”, it refers to being able to deliver data across these two frequencies.

802.11ac (WiFi 5)

802.1ac-compliant devices operate in the 5 GHz frequency space. With Multiple Input, Multiple Output (MIMO) – multiple antennas on sending and receiving devices to reduce error and boost speed – this standard supports data rates up to 3.46Gbps. Some router vendors include technologies that support the 2.4GHz frequency via 802.11n, providing support for older client devices that may have 802.11b/g/n radios, but also providing additional bandwidth for improved data rates.

802.11ax (Wi-Fi 6)

Also called High Efficiency WLAN, 802.11ax aims to improve the performance in WLAN deployments in dense scenarios, such as sports stadiums and airports, while still operating in the 2.4GHz and 5GHz spectrum. The group is targeting at least a 4X improvement in throughput compared to 802.11n and 802.11ac., through more efficient spectrum utilization.

The rise of 60GHz V-Band Technology

60GHz V-Band Wireless Technology

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 is expecting WiGig-certified products to arrive in 2015. (See Wi-Fi Alliance, WiGig Align to Make WiFi Super Fast.)

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. (See Pushing 60.)

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.

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. (See FCC to Enable Fast Streaming With New 60GHz Rules.)

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

Gigabit Wireless Links using V-Band 60GHz Millimeter Wave MMW Technology

Gigabit Wireless Links using V-Band 60GHz Millimeter Wave MMW Technology

So-called “V-Band” refers to high frequency microwave signals in the Millimeter Wave radio bands which enable high capacity wireless communications.  The band is useful for moderate distances up to around 1km with clear “line of sight”, and for short-range mobile devices.  In many countries, V-band is “Unlicensed” (license free) which encourages widespread use.

What is 60GHz V-band technology?

The V band (“vee-band”) is a standard designation by the Institute of Electrical and Electronic Engineers (IEEE) for a band of frequencies in the microwave portion of the electromagnetic spectrum ranging from 40 to 75 gigahertz (GHz).The V band is not heavily used, except for millimeter wave radar research and other kinds of scientific research. It should not be confused with the 600–1000 MHz range of Band-V (band-five) of the UHF frequency range.

CableFree V-Band 60GHz MMW Link
CableFree V-Band 60GHz MMW Link with High Gain parabolic antenna

The V band is also used for high capacity terrestrial millimeter wave communications systems. In the United States, the Federal Communications Commission has allocated the frequency band from 57 to 71 GHz for unlicensed wireless systems. These systems are primarily used for high capacity, short distance (less than 1 mile) communications. In addition, frequencies at 70, 80, and 90 GHz have been allocated as “lightly licensed” bands for multi-gigabit wireless communications. All communications links in the V band require unobstructed line of sight between the transmit and receive point, and rain fade must be taken into account when performing link budget analysis.

Applications for 60GHz V-band

Very short range Wi-Fi

The Wi-Fi standard IEEE 802.11ad utilizes the 60 GHz (EHF microwave) spectrum with data transfer rates of up to 7 Gbit/s for very short ranges of up to 10 metres (33 ft).  Also the newer IEEE 802.11ay uses the same band.  Where 802.11ad uses a maximum of 2.16 GHz bandwidth, 802.11ay bonds four of those channels together for a maximum bandwidth of 8.64 GHz. MIMO is also added with a maximum of 4 streams. The link-rate per stream is 44Gbit/s, with four streams this goes up to 176Gbit/s. Higher order modulation is also added, probably up to 256-QAM.

Mobile backhaul

As mobile operators need more and more bandwidth, they are turning to new frequency bands to lower their wireless backhaul costs. Both license-exempt V band spectrum (57-71 GHz) and E band spectrum (71-76 GHz, 81-86 GHz and 92-95 GHz) have clear technological and economic advantages. The 27 GHz allocated in these bands allows multi-Gigabit per second capacities far exceeding the 6-38 GHz bandwidth-limited frequencies.

In the V band and E band spectrum, wireless systems can utilize the significantly larger allocated spectrum and channels to deliver multi-Gigabit data rates. This enables a simple, robust, and low cost modem and radio design. Thus, V-Band and E-Band, millimeter-wave wireless systems provide significant cost advantages over 6-38 GHz wireless systems – allowing scaling capacity to Gigabit capacities, without additional radio equipment and licensing fees.

Wireless broadband

Internet service providers are looking for ways to expand gigabit high-speed services to their customers. These can be achieved through fiber to the premises broadband network architecture, or a more affordable alternative using fixed wireless in the last mile in combination with the fiber networks in the middle mile in order to reduce the costs of trenching fiber optic cables to the users. In the United States, V band is unlicensed. This makes V band an appealing choice to be used as fixed wireless access for gigabit services to connect to homes and businesses.

Satellite constellations

As of March 2017, several US companies—Boeing, SpaceX, OneWeb, Telesat, O3b Networks and Theia Holdings—have each filed with the US regulatory authorities “plans to field constellations of V-band satellites in non-geosynchronous orbits to provide communications services,” an electromagnetic spectrum that had not previously been “heavily employed for commercial communications services.”

V-Band Regulations and Licensing

In many countries, V-band is “Unlicensed” (license free) which encourages widespread use.  A few countries retain 60GHz for licensed or defence applications.  The specific frequencies which are allowed to be used can vary between different countries.
