La banda de 4.9GHz se ha convertido en un recurso crítico para proveer el acceso y control de cámaras de video y facilitar así la seguridad pública. Esto no es una tarea insignificante… Cuando un sistema de video vigilancia se está utilizando para monitorear artículos preciados o para salvaguardar la vida de ciudadanos, una red inestable podría tener consecuencias no deseadas. Desde la vigilancia de negocios hasta sistemas que mantienen al público informado en caso de una emergencia, estos servicios deben ser totalmente confiables. Y de la misma forma deben ser las redes que usan estos servicios. Nadie quiere oír de alarmas que no funcionaron o de cámaras que no captaron las imágenes de un delito por causa de una mala conexión o radio interferencia.


Para servicios críticos, su red no puede operar con soluciones a medias. Su red necesita estabilidad, seguridad y rendimiento de primera, con equipo que haya demostrado alrededor del mundo que puede operar aún en lugares donde la radio interferencia es un problema. Los usuarios de estos servicios de seguridad así lo reconocen. Su red necesita una solución que no solo cubra las necesidades inmediatas de sus clientes, sino también las futuras. Puede ser tentador desplegar soluciones de calidad cuestionable, con el fin de mantener un costo bajo, pero cuando la red no pueda desempeñarse ante la carga de tráfico, alguien deberá responder ante el cliente. Le garantizo esa no es una conversación fácil de tener…

Usted necesita una solución confiable y capaz de crecer con su negocio, que opere en la banda de 4.9GHz, a un costo razonable. Sin excusas y sin reservas…

When we think of the Industrial Internet of Things (IIoT), the word measurement sounds comparatively antiquated. But at its core, the promise of IIoT is built on millions of measurements taken on a regular basis. When properly analyzed – taking into account a holistic view of where measurements were collected in the network and how they affect overall operations – this data then becomes the foundation for change. Visualizing and analyzing this data is the key to realizing untapped revenue or removing hidden inefficiencies.  Blog-Atul_ICT_IIoT.jpg

Cambium Networks has long believed that what cannot be measured cannot be improved – yet measurement can only be accomplished with a strong communications backbone. Thus it was heartening to read this very thought in an Accenture report – The Growth Game-Changer: How the Industrial Internet of Things Can Drive Progress and Prosperity. The report details how IIoT can drive growth and prosperity across economies; emerging markets can even leap-frog developed nations through implementing IIoT technologies. However, this can only occur if a country has a strong communications backbone as 85 percent of the IIoT is based on legacy infrastructure, a statistic the report cited from this Gigaom article. 

We have deep experience in building large communities and their information and communications technology (ICT) infrastructure. Through our PTP technology, places that had never been connected before can now share information. Through our PMP technology, people can learn from each other and solve one another’s problems. This is just the tip of the iceberg in truly moving the needle to connect the unconnected.  

In future blog posts, we’ll offer examples of the local agencies and government entities we’ve worked with to bring about sweeping technological change, vaulting the unconnected into the digital world with incredible measureable results. We hope that these stories will serve as a blueprint to those looking to bridge the digital divide with wireless broadband, and from there, implement IIoT technologies for greater growth and prosperity. If this fits the description of your network, we’d love to hear from you. Tell us your story on our forum on by emailing [email protected]


The showers have finished, the clouds cleared and the prematurely darkened skies have lightened up. Perhaps we will get this soccer game in after all, and that 45-minute mad dash from the office to see the last game of the season would not be for naught! Sure enough, the boys made it on the field. They were up 1-0 and were pressing fast for another opportunity when the sirens went off. Natural instinct took over and two actions took place almost simultaneously. The referee immediately blew his whistle, halting the drive, and instructed the boys to proceed immediately their parents’ cars. I, and all of the other parents, looked to the sky and asked ourselves, “Why are the sirens going off when the sky is clear?”Blog-Imhoff-lightning.jpg

The referee absolutely took the right action and cleared the field. As there was no shelter at the field, he required the teams and fans to enter their vehicles. I didn’t time it but in less than three or four minutes, everybody was safe where they needed to be. Fortunately, there were no lightning strikes that Wednesday evening. 

However, to answer the question above, the sirens went off because lightning can travel up to 25 miles from its source. The detectors had recognized the conditions were optimal – safety comes first.  A few additional facts for the numbers oriented readers as Mother Nature is not to be trifled with!

  • Over 100 cloud-to-ground lightning strikes occur every second, and

  • On average, 55 people annually are killed by lightning in the United States alone.

Unlike all of the other parents on the sidelines, I happened to make an additional observation when I was sky gazing and hunting for the offending lightning cloud. Several of the light stanchions surrounding the field had video surveillance cameras mounted on them and connected to radios for backhaul. I suspect that I am the only parent that would not only notice but also be pleased to see the use of our technology! As the radios were mounted too high to tell, I wondered if the installer had correctly used surge suppression devices with the installation.

While I live in the Midwest of the United States, which is prone to electric storms, lightning occurs around the world. This past Monday we hosted customers from a large Indian oil company, who attested to the frequency of lightning in their geography and the criticality of surge suppression. Use of surge suppression protects the equipment and preserves the cost of installation typically for pennies on the dollar. Whether it is a relatively expensive licensed microwave node or a relatively inexpensive CPE device, I would hope that network operators are protecting their equipment with a modest investment in surge suppression elements and ensuring the installation is properly grounded. On the CPE side, what network operator wants to explain to a home owner that a surge originating in their equipment transited into the home and wrecked the sensitive electronics plugged in the mains because it wasn’t interrupted with a low cost surge suppressor? 

All Cambium Networks products are designed with electrical surge in mind and have recommendations on best practices for grounding equipment and achieving protection against lightning-induced electrical surges. We design and manufacture our own lightning protection units specifically for use in any installation environment, whether mounted at the top of a mast or on the side of a home.  If your standard operating procedure is to not install surge suppression, take a few minutes and calculate the return on investment, and then consider the risk/reward trade-off. If your standard operating procedure calls for the use of surge suppression, when was the last time you audited your crews’ work for proper installation and grounding? 

Roughly 20 minutes after the first siren, the “all clear” signal sounded and play resumed. With a 3-0 victory in hand, the boys ended the spring season on a high-note, dad got credit for making the game, and everybody went home safe! 


The electric utility industry continues to enhance security measures in light of potential natural disasters and cyberattacks to the grid. To this end, in the United States the federal government via NERC (North American Electric Reliability Council) provides guidelines and auditing oversight, particularly in the area of Critical Infrastructure Protection (CIP). The latest generation of requirements (NERC-CIP v5) will be coming into effect over the next several years. Under these regulations, each utility is subject to an audit of its compliance to 11 sets of NERC-CIP requirements (CIP-001 to CIP-011). main.jpg

As technology evolves, NERC continuously reviews its definitions of cyber assets, physical security perimeters and electronic security perimeters. Think of cyber assets as any device with an Ethernet port running a routable protocol such as TCP/IP. NERC-CIP says that these devices must be protected in a wide variety of ways including password protection, and account for physical attacks, DoS attacks, etc.  

We get a lot of questions about whether our wireless broadband solutions are NERC-CIP compliant.  As it turns out it isn’t a piece of equipment that is compliant but rather an organization that is audited to be compliant. For example, an organization might state that it will require password changes with certain complexity rules as its policy.  The auditor would look to see that such organizations have implemented the procedure and that their network equipment supports this capability.

As such, a more appropriate question would be, “How does a particular piece of equipment enhance the cybersecurity of my organization to assist compliance to NERC-CIP?” At Cambium Networks, we provide specific answers to this question for all of our products as compliance requirement change. 

One new development in NERC-CIP v5 is a refined definition of the term “physical security perimeter.” In the past this meant a “6-wall” physical barrier to unwanted intrusion – 4 walls, a floor and a ceiling.  This is clearly a problem in large outdoor facilities with generators that now have TCP/IP management ports. So the 6-wall language has been removed. In its stead is a NERC-CIP requirement for solutions that provide a combination of video surveillance, intrusion detection and identity-based access mechanisms such as key-cards and lift-gates.  

Wireless broadband plays a key role in providing this remote monitoring and security.  Without trenching or running wires, and without paying leased line monthly fees, a utility’s cyber-security team can dramatically reduce the cost and time to achieve compliance. As an example, Cambium Networks’ PTP 650 has many features supporting these types of deployments: roles-based security, direct power to PoE video cameras, over-the-air encryption, security transaction audits and SNMPv3/https alarm generation for intrusion detection. 

Although the current NERC-CIP definition of a cyber-asset does not encompass communication networks, NERC has requested that these communications be assessed in the future. Cambium Networks products remain at the ready to support utility companies’ compliance requirements today while also addressing their future needs.

Availability and ready access to unlicensed or lightly licensed spectrum in the United States has directly contributed to both economic development and social advancement.  Today it is estimated that over three million users in the United States receive high capacity broadband access from fixed wireless service providers, principally using unlicensed 5 GHz and lightly licensed 3.65 GHz spectrums.  An untold number of sensors, actuators, and other control systems utilized by railways, electric utilities, and oil and gas firms are networked together utilizing in part that same 3.65 GHz and 5 GHz spectrum – a cornerstone to what we call today the Industrial Internet.  Schools – from elementary to university – extend their classroom to remote learners, connect buildings, and ensure the safety of their campuses through the use of unlicensed spectrum.  Demand and utilization has never diminished and fixed wireless network equipment is keeping pace – with solutions on the immediate horizon capable of supporting over 750 Mbps per Sector and achieving spectral efficiency in excess of 37 bits/second/Hertz.  The limiting factor on this economic and social engine has been access to adequate spectrum.Blog - FCC 15-47_698x400.jpg

On the 17th of April the FCC adopted Report and Order and Second Further Notice of Proposed Rulemaking (FNPR) 15-47, the latest iterative step in opening up an additional 100 MHz of spectrum in the 3550-3700 MHz band for commercial use.  15-47 comes on the heels of FCC 14-30 First Report and Order which opened up 5.15 – 5.25 GHz for outdoor use.  FNPR 15-47 advances the definition of the Citizens Broadband Radio Service (CBRS); including the establishment of Priority Access Licensee (PAL); General Authorized Access (GAA); the Spectrum Access System (SAS); and the governance of the Grandfathered Wireless Broadband Licensee through April 17, 2020.

The FCC has done an elegant job in balancing the needs of critical infrastructure customers like water and electric utilities, rail operators, oil and gas firms, and government whose mission dictates committed and unequivocal access to spectrum via the PAL.  The FCC has also ensured significant access, generally not less than 80MHz, to unlicensed spectrum via the GAA.  Perhaps most importantly they have protected the investment in and ensured the integrity of installed networks using the 3.65 GHz band, allowing them to continue to build out their networks through August 2020 in a protected state, and then transitioning to GAA status.  RCR Wireless News is reporting that Google is already testing their SAS service which bodes well for a timely implementation of the CBRS and the additional 100 MHz of spectrum that it opens up.    

Considering that establishment of the CBRS is a reallocation of spectrum previously set aside for national defense, with utilization in some locals, it is not surprising that not all questions have been anticipated or answered; so a bit more work to be done on the end-to-end schedule and closing the gaps on execution.  Cambium for its part is confident that its existing PMP 450 network equipment will align to the forthcoming certification criteria; and will continue to enable build-out of existing networks.  In short order Cambium will be publishing a FAQ that we expect to answer many of the questions or customers and prospective users of the existing 3.65 GHz spectrum have.  All-in-all, this is a positive step forward for a wide range of network operators from private to service provider to public service. 

It is also not surprising that the European Union is undertaking efforts free up spectrum across its member states to enable fixed wireless networks to connect the unconnected and under connected – more to come on that topic in a future note.
