In the United States, President Obama and the Department of Homeland Security (DHS) have designated sixteen industries as Critical Infrastructure important to the health and well-being of all citizens. Critical Infrastructure industries cover the production and distribution of food, water and energy as well as the communications networks that we use to share information. November was designated by DHS as National Critical Infrastructure Security and Resilience month and the DHS continues to publish information about critical infrastructure and provide guidance about what organizations and individual citizens can do to play their part in protecting these assets. These same critical infrastructure concepts and priorities are being put in place globally as well.

Wireless Broadband has a major role to play in securing critical infrastructure. Here are four examples.
1. Video surveillance and remote sensing - Wireless broadband allows organizations to place cameras where they are needed, not just where there is a fiber cable or copper wire available.
2. Centralized control - By providing more broadband capacity deeper and wider in large-scale operations, security organizations can deploy applications such as centralized gate access security and remote Internet access allowing remote security personnel and other field employees access to latest information and alerts with more detail.
3. Backup connectivity - Wireless broadband can be deployed as a resilient private network backup to wire-line communications. If an emergency situation arises that causes the public network to be out of service or fiber and wire networks to fail, a wireless broadband connection can serve as an instant-on backup network to keep important communications flowing.
4. Disaster recovery - In the case of a severe outage or disaster situation, wireless broadband networks can be rapidly deployed by first responder and disaster recovery specialists to provide voice, video and data communications within hours of identifying the need.
Cambium Networks brings a unique set of capabilities to support these initiatives with a broad range of wireless broadband point to point (PTP) backhaul and point to multipoint (PMP) access solutions. The systems are rapidly deployable and bring tens to hundreds of Mbps to all of the important applications described above. Cambium has products in sub-6GHz unlicensed and lightly licensed bands, the 4GHz NTIA and NATO Band IV spectrum as well as licensed microwave solutions from 6 to 38GHz. And with our PTP 600 and PTP 800 products, Cambium delivers FIPS 140-2 validated solutions to meet Federal Government encryption security requirements.To learn more about how Cambium Networks is helping Protect Critical Infrastructure, visit our website at: www.cambiumnetworks.com or attend our Webinar “Securing Critical Infrastructure” on Thursday, December 5th at 9AM CST.

When a pop superstar like Rihanna comes to town, broadband demands multiply around the performance venue. The last thing a service provider wants is complaints of slow or non-existent connectivity when fans are attempting to upload concert photos to social media. While on the road, Rihanna’s team relies on the local service provider to create and build a high performing network – a network that may exist for only a day or two. With strict demands and tight schedules, there is no room for error.
Recently, Rihanna performed at the Hiram Bithorn Stadium in San Juan, Puerto Rico, and needed broadband connectivity so that voice and data services would be available in her team’s portable equipment trailers. They looked to Aeronet Broadband, a local service provider, to provide reliable and secure broadband connectivity for tripleplay services (voice, video and data) in order to coordinate lighting, sound, choreography and logistics for the event.
Leveraging its extensive PMP 450 network, Aeronet created new drops from nearby PMP 450 radios to the concert arena, providing the high throughput and symmetrical bandwidth needed to ensure a low latency connection. Not only was the installation successful, but Aeronet lived up to its tagline: “The most reliable provider in town.”
All successful businesses require superior broadband connectivity, whether you’re a concert promoter or the head of your employer’s IT department. Whether you’re looking to expand to new markets, create temporary networks or implement a disaster recovery plan, broadband can help. With today’s wireless communication technology, companies can deploy infrastructure rapidly without the extensive labor and maintenance costs associated with wire-line connectivity. Cambium Networks’ reliable and secure solutions provide today’s businesses with rock star quality broadband connectivity where you need it, when you need it.

QAM (Quadrature Amplitude Modulation) is widely used for digital radio communication. Variants of QAM are also used for many wireless and cellular technology applications. The advantage of using QAM is the ability to carry more bits of information per symbol. As higher modulations are used, more and more data can be packed into the frame. Throughput increases as modulations go up: from 16-QAM to 64-QAM and now to 256-QAM. We can increase the data rate of a link by selecting a higher order of QAM.
While higher order modulation levels offer much faster data rates and higher levels of spectral efficiency for wireless broadband systems, the use of these types of modulation comes at a price. They are less resistant to interference and noise and need to be constantly adapted to current RF conditions. As a result, radio communication systems started to implement dynamic adaptive modulation techniques. These methods test channel conditions periodically and adapt a modulation scheme to obtain the highest data rate for a given set of conditions.
At Cambium Networks we are committed to the highest quality on your wireless link. Our newly released PMP 450 Access Point is designed using dynamic 256-QAM which is a higher modulation rate than the currently offered 64-QAM. Higher capacity offers wireless service providers a unique opportunity to use the new PMP 450 solution for IPTV. Among other advantages, the new PMP 450 is interoperable with existing 430 SMs, offering the full benefits of the latest PMP 450 APs – higher capacity (125 Mbps) and an easier migration path to the latest platform.
Solutions that are labeled “field proven” and “agency vetted” carry particular significance to federal government network operators, information assurance officers, and spectrum managers who know that considerable effort has been placed in developing these technologies. For Cambium Networks, these descriptors signify that our wireless broadband solutions have met strict security requirements in rigorous lab evaluations and have performed reliably in some of the harshest field conditions where connectivity is an essential component in theater operations. For federal network operators, these words also mean hassle-free spectrum approval.
We work closely with the DoD and other agencies to create voice, video and data solutions that comply with stringent government requirements. For instance, our PTP 600 offering is the only PTP microwave radio that is JITC / UC-APL approved. In addition, Cambium’s PTP 800 is the only 7/8 GHz FDX Microwave that combines native FIPS 140 validation with DoD (J/F-12) requirements and federal, but non-DoD (NTIA SPS), RF approval.
Of course, there is much more to the federal government than defense. Cambium also provides solutions for non-DoD agencies that need broadband connectivity for leased-line replacement. Some other applications where we’ve deployed our solutions include border security, disaster recovery, infrastructure protection and maritime monitoring.

As your network increases in size and complexity, wouldn’t it be great if you could leave the performance analysis, configuration fine-tuning and overall optimization to the network itself? The promise of self-optimizing networks is to build the intelligence into the network so the humans in charge can focus on growing the business and planning for the future. Cambium Networks has taken a significant step towards realizing this vision with the Dynamic Spectrum OptimizationTM (DSO) feature on the recently launched PTP 650 wireless microwave backhaul solution. DSO automates the process of selecting the most reliable channel among all those available – even in a constantly changing RF environment – without impacting the flow of critical business information.
The traditional approach to channel optimization requires a network engineer to react to system performance issues by taking the system down to perform spectrum analysis, causing a system outage for the end user. Oftentimes, this means middle of the night maintenance windows when the environment may be quite different than peak traffic periods and problems are difficult to reproduce. While the system is down, the radios are put into a spectrum analysis mode to collect a snapshot of information about what is happening at that time. Engineers analyze the results, determine the actions to take, make manual configuration changes and finally restore the network to operation to see if they were successful. This laborious monitoring process repeats on a regular cadence or on an as-needed basis.
With DSO, Cambium Networks has taken a completely different approach. Through this technology, the network self-optimizes automatically, accurately and consistently all without human intervention and impacting the payload data. When an alternate channel is identified that will provide more reliable communications and a higher fade margin, the system automatically jumps to this better channel – again with no impact to customer data. This process is automated, repeatable and occurs constantly in real-time, reacting immediately as the environment changes. Of course, the solution lets the network engineers control as much or as little of this process that they want and all the data and configuration changes are stored for later review.
Dynamic Spectrum Optimization is just one feature among many that make the PTP 650 the highest performing, most reliable, most secure and most versatile sub-6 GHz wireless microwave backhaul product on the market.

Connectivity is in high demand, and network operators use Point-to-Point backhaul links to provide backbone connectivity to reach a desired service area. Because they are used to extend connectivity, these links must span long ranges and provide high throughput. Because they are the vital link to access network connectivity, they must be reliable and secure. Network operators need to KNOW detailed network performance and design in quality. Network World looks at many Sub-6 GHz has named the PTP 650 as a Product of the Week for the following reasons:
The highest level of spectral efficiency
450 Mbps of throughput in a 45 MHz channel width
The only microwave backhaul with a real-time spectrum analyzer onboard
The PTP 650 can extend your network and provide industry leading reliability. Before you even purchase the link, the free LINKPlanner tool from Cambium Networks enables you to plan your network efficiently by entering the location of the source and destination. LINKPlanner will automatically calculate the throughput and performance so that you can set Service Level Agreements (SLAs) that you know you can meet.
