Five-Nines Availability and RCA’s Top Secret Communication Project
Five-nines (99.999 percent) availability is a concept that is familiar in wireless engineering. Dick Laine, principal engineer of Aviat Networks, compares five-nines availability to 78-rpm records in our most recent episode of the Radio Head Technology Series. As he...
Utilities Must Work Closely with Wireless Vendors on Smart Grid
UTC Telecom 2012 is the annual show of the utilities industry in North America. New technologies and products were displayed to help the industry with its latest challenges. Also various utilities shared their experiences in implementing new networks to deliver...
3 Models for Microwave Link Error Performance? Laine Explains
As most radio engineers know, Vigants calculations, which are discussed in a broadly cited Bell System Technical Journal article, are widely used to determine reliability or error performance for microwave link design. In Video 2 of Aviat Networks’ popular Radio Head...
Dick Laine’s 4 Keys to Successful Transmission Engineering of Microwave Links
Transmission engineering of a microwave link requires creativity and skill. So if you are looking for inspiration as well as high-quality wireless engineering instruction look no further than the "Radio Head Technology Series." Radio Heads is a collection of videos...
Coverage Maps for New Wireless Spectrum Available to Fixed Services
As we blogged last summer, the FCC has released 650 MHz of new wireless technology spectrum for Fixed Service wireless communication technology operators. Now Comsearch, a leading provider of spectrum management and wireless engineering services in the US, has...
Wireless Network Services: Disaster Monitoring and Recovery
In 2011, the United States experienced its worst tornado outbreak in more than 50 years. And communication systems were not spared from the carnage. In the video below, Robert Young, senior manager for Aviat Networks’ Americas TAC/NOC explains how the company’s San...
3 Truths about High Fade Margin in Point-to-Point Path Design
Currently, there are no known ITU or North American error performance standards that address outage probability on all-packet point-to-point microwave radios. According to both the Vigants and ITU-R P.530 models, the probability of outage (i.e., Severely Errored...
10 Things to Know About the Status of Asymmetrical Wireless Backhaul
Last autumn we wrote about potential plans from a microwave competitor regarding using asymmetric band plans for point to point microwave communication links. To update this topic, we have put 10 things in parentheses that you should know about the current status of...
Diverse Wireless Network Topologies Cost Savings
To compare how different wireless backhaul network topologies perform under the same operating scenario, let’s analyze how a traditional hub-and-spoke and a ring configuration compare in connecting the same six sites (See table below). For the hub-and-spoke...
Are Auctions an Appropriate Way to Allocate Microwave Spectrum?
Recently the U.S. Congress requested information from the FCC regarding the usage of the 11, 18 and 23GHz microwave point to point bands. This move is seen by many industry watchers as the first step in preparing these bands for auctioning. Auctioning spectrum is seen...
A Timely Update on Wireless Security
Traditionally, microwave networks have been unsecure—unsecure as far as any purpose-built payload encryption or secure management is concerned. Until recently, it was deemed essential only for the most confidential microwave communications of financial firms, defense...
