The usual players all showed up at this year’s Mobile World Congress in Barcelona with lots of improved devices, but no real game-changing breakthroughs... |
Orthogonal Frequency-Division Multiplexing (OFDM): FAQ tutorial
What is OFDM? How does it work? And how can you use it in your next design? Get the answers to these questions and more in this FAQ Tutorial on this pervasive wireless technology. ...
Antenna Designs and Considerations for WiMAX Systems
Much debate surrounds the comparative benefits of WiMAX and LTE. Despite this ongoing debate, both 4G services rely on a MIMO operation as a key enabler for enhanced performance. MIMO, which typically requires multiple antennas, is not a simple implementation because of space constraints, especially in small mobile devices. Yet designers can use it effectively with some key guidelines in mind. ...
IEEE 1588v2 Sets A New Paradigm for Packet Synchronization
Before telecommunications carriers can leverage cost-effective Internet Protocol (IP) networks to handle the increased bandwidth expected from 3G and 4G services, they need to know the issues surrounding time synchronization and the solution provided by IEEE1588v2. Officially named IEEE 1588-2008, this standard addresses network-based timing and synchronization. ...
Wireless Trends And Directions Emerge At CTIA
I like the International CTIA Wireless show. It does a good job of pointing the direction for the cellular industry and showcasing the latest products and services. Attendance in Las Vegas was down to 34,000, compared to 44,000 last year. Yet the show was very positive and upbeat overall as key trends like touchscreens, app stores, netbooks, WiMAX, TV, and M2M seem to defy the global economic downturn. ...
International CTIA Wireless 2009, Day 2: Data, WiMAX, And Netbooks On The Move
The second day of the International CTIA Wireless 2009 conference in Las Vegas brought keynoters with bright outlooks for key areas of the industry. Steve Largent of CTIA discussed the growth in data service revenue. Ben Wolff of Clearwire was optimistic about WiMAX’s future. Eric Topol, director of the Scripps Translational Science Institute looked at wireless medical apps. And, Robert Boch of Microsoft examined the growing netbook phenomenon. ...
Five Steps To Effective Mobile Web Design
The increasing power of smart phones is leading to increasing user demands for Web access and functionality. Successful Web designers will understand their users, keep their sites simple and intuitive, make their sites personal, cater to each device’s capabilities, and adapt their sites to each device. ...
Registration Open For Basestation Conferences
Registration is underway for the Next Generation Networks & Basestations event as well as the Green Basestation Summit, scheduled for April 20-24 in Bath, the U.K. These conferences will explore the latest in LTE, WiMAX, HSPA’s evolution, femtocells, operating and capital expenditures, backhaul, spectrum, fuel cells, wind and solar power, load balancing, remote heads, and legacy upgrades....
Shining A Light On LTE
While the market ultimately will decide which standards constitute the so-called “fourth generation” or 4G, presently IEEE’s WiMAX and 3GPP’s Long Term Evolution (LTE) are under scrutiny and development. The latest standard version of LTE offers enough specifics to fuel basestation and handheld-device design. Along with those specifics, we’ve seen a marriage of instruments and specialized software to enable developers to make reference designs that meet LTE’s exacting requirements....
Multicore DSPs: Less Is More In Basestation Design
Multicore DSPs are ideal for demanding 3G and 4G applications in today’s basestations—if you know how to harness that power....
ATCA Supports The Move To An All-IP Carrier-Grade Transport
Wireless infrastructure is in the process of expanding to IP-based LTE with new technologies like ATCA being introduced to support higher-bandwidth data traffic along with existing signalling traffic. ...
