The narrowbanding mandate from the Federal Communications Commission (FCC) has businesses and government entities working to retool their two-way radio systems in the face of stiff penalties and a Jan. 1, 2013, deadline. The FCC set forth its narrowbanding initiative in 1992 with the ultimate objective of increasing capacity and efficiency for the industrial/business and public safety radio pools in the private land mobile radio services category.
With the progress of WAN access technologies such as DOCSIS 3.0, GPON, and VDSL2, there is now more pressure than ever to over hall the bottle- neck of Internet traffic that is still limiting in-home network capacities. For instance, Telco and Cablecos alike have spent hundreds of millions of dollars upgrading this infrastructure to deliver massive data pipes to millions of homes in North America and around the world.
Canada’s beautiful capital city of Ottawa has proclaimed June 10 – 15, 2012 as IEEE Week to coincide with the IEEE International Conference on Communications (ICC 2012), which will be held on the same dates at the newly, opened, $170 million Ottawa Convention Centre. Themed “CONNECT – COMMUNICATE – COLLABORATE,” IEEE ICC 2012 is expected to host thousands of industry professionals, scientists, academics and government officials, who will attend nearly 1,500 presentations highlighting the entire range of communications technologies, while touring Canada’s beautiful capital city and participating in wide-ranging local festivities.
The IEEE International Conference on Communications (ICC), the leading international venue dedicated to the advancement of wireless and wireline communications worldwide, has initiated registration for its first “paperless+” annual event to be held June 10 – 15 at the Ottawa Convention Centre in Ottawa, Canada.
Q: What are some of the most challenging issues when designing products for remote base station applications? Damian Anzaldo, Communications Segment Manager, Maxim Today’s remote base stations must be power efficient, smaller in size and deliver excellent radio performance. Power efficiency is important to improve mobile operator total cost of ownership, help reduce CO2 emissions and minimize heat dissipation to address passive cooling requirements.
In more and more consumer and industrial applications, end users appreciate the convenience of connectivity without cables, and the license-free 2.4 GHz ISM band is often the most suitable choice. Such applications include body area networks, wireless sensor networks, active smart labels, home/building automation, and interactive remote controls.
The Challenge: Developing an improved method for applying digital signal processing to correct nonlinear RF impairments, and validating the approach using real-world wireless signals. The Solution: Migrating simulation-only code to NI LabVIEW software and using real-time digital signal processing (DSP) with two NI USRP™ (Universal Software Radio Peripheral) software defined radios to specifically address nonlinear amplifier impairments and validate algorithms with real-world signals.
Today’s radio designs, and other RF communication equipment, are being made to consume less power while occupying less physical space, which leads to less available board area for heat sinking. ADI has kept pace with these requirements by creating the ADL5605 and ADL5606 two-stage 1 Watt RF driver amplifiers.
How Utilities Can Leverage Smart Grid Automation to Comply with FAA-mandated Obstruction Light Monitoring RequirementsMay 29, 2012 9:35 am | by Jason Wilson, Sr. VP of Business Development & Product Management for On-Ramp Wireless | Comments
New transmission lines are being built to meet growing demands for electricity, improve reliability of power delivery, and meet requirements for procuring larger percentages of energy from renewable sources. As new transmission corridors are approved and the projects are initiated, the FAA requires notification by utilities of the construction or alteration of any structure that may affect the National Airspace System.
It might seem hard to believe but the mobile phone was first introduced to the UK in 1985. Just twenty seven years later and the device that we now love is hardly recognisable to those first Motorola handsets. And it’s not just the size and battery life that’s changed. Let’s face it, if you were to upgrade your handset tomorrow, would you just be looking for one that can make calls! Considered the top executive toy, the mobile phone became the status symbol of the Yuppie - short for "young urban professional" or "young upwardly mobile professional".
Your home and office contain a host of technologies working to improve the way you live. From monitoring energy intake and usage, to controlling your appliances and lighting, ZigBee is a protocol that is changing the way we live — and in some cases, we don’t even realize it. ZigBee is the only standards-based wireless technology designed to address the unique needs of low-cost, low-power wireless sensor and control networks in just about any market.
Bill Boldt, Sr. Business Development Manager, Fairchild Semiconductor With cell phone companies using merchant chip sets, they must find new ways to differentiate how their products look, feel, sound; and what they enable users to do. As for sound, in the not-too-distant past handset users expected very little in the way of audio performance, so whatever amplifier was built into the core chip set was good enough.
Enterprise Mobility Applications (EMAs) will transform competition across all businesses. That's the conclusion of a Wipro survey of 161 North American companies whose executives are at the forefront of EMA deployment. How confident are these executives that sweeping change is on the way? In the area of sales productivity alone, a whopping 88 percent said they believe EMAs will improve the win rate, and 82 percent said EMAs will increase the average deal size.
By Lori Sylvia, EVP Marketing, Red Bend With the tremendous power of smartphones, and the increasing amount of information that can be stored on them, lost and stolen devices have become one of the biggest threats to consumer privacy and to Enterprise security. Think about it. A lost smartphone isn't just an inconvenience, it opens the door to email accounts, banking apps or any saved site or app linked to a credit card.
By Dr. Ian F. Akyildiz, Ken Byers Chair Professor, School of Electrical and Computer Engineering, Georgia Institute of Technology The concept of nanotechnology was first pointed out by the 1965 Nobel laureate physicist Richard Feynman in his famous speech entitled “There’s Plenty of Room at the Bottom” in December 1959.
