‘The Cloud’ and What it Means for Wireless Technology
The cloud is an all-encompassing thing that’s actually been around for a while (e.g. distributed computing, Network Attached Storage). Most of it exists today in the enterprise but is being pushed to the Internet and rebranded “The Cloud.” This affects three wireless...
Managing Wireless Networks with Element Management Systems
Managing a wireless network is essential. Radios, routers and third-party add-ons control vast amounts of valuable user data. Any wireless network downtime damages the user’s business and the operator’s long-term reputation. Thus, operators need a powerful but...
Evolution of Microwave: History of Wireless Communications
Microwaves are as old as the beginning of the universe. Well, they've been around for at least 13.7 billion years—very close to the total time since the Big Bang, some 14 billion years ago. However, we don't want to go that far back in covering the history of...
Hybrid Microwave for Wireless Network Backhaul Evolution
There is no one-size-fits-all wireless network backhaul solution. What will work for some operators' mobile backhaul will not work for others. Many operators have large installed bases of TDM infrastructure, and it is too cost-prohibitive to uninstall them wholesale...
Antennas: Why Size is Important for This Wireless Equipment
In response to the recent FCC docket 10-153, many stakeholders proposed relaxing antennas requirements so as to allow the use of smaller antennas in certain circumstances. This is an increasingly important issue as tower rental costs can be as high as 62 percent of...
Mobile Security Requires More Than Secure Wireless Devices
When people think of mobile security, they usually think of encryption for their smartphones, tablet computers such as the BlackBerry PlayBook or other wireless devices. Or they think of a remote "wipe" capability that can render any lost device blank of any data if...
TDD or FDD Wireless: That is the Question!
TDD, or Time Division Duplex, where a single radio channel is used to send and receive data, has been a common technique employed in unlicensed microwave transmission bands, such as 2.4 and 5.8GHz. The advantage of TDD is a simplified and lower cost design, often...
Ethernet OAM Meets Demands on Microwave (Wireless) Networks
Ethernet OAM (Operations, Administration and Maintenance) can help mobile network operators and other transport providers meet the ever-growing demands for increased bandwidth across the backhaul network as well as meeting the equally important demand for quality and...
Comprehensive Embedded Security in Microwave (Wireless) Networks
[scribd id=52721268 key=key-r5hop2rgq61ylrwh1ny mode=list] The current and ongoing migration toward IP networking on backhaul networks supports rising data volumes, which is increasing the opportunities and motivations for data and call interception. As data volumes...
Security Focus as Wireless Traffic Rises, Mobiles Get More Powerful
Even though microwave communications have some built-in security-like features such as scrambling, narrow beamwidth, proprietary airframe, coding and other factors, it is not very hard for them to be broken by those with the proper expertise. Some vendors even openly...
The World’s Longest All-IP Microwave Link
Successfully Implementing a 193-km Microwave Link over Water to Deliver 99.9995 Percent Availability Introduction For most designers of microwave transmission paths, engineering a reliable link over water can be a daunting task. Reflections off the water surface can...
Synchronization Over Microwave Mobile Backhaul Networks
[scribd id=52720546 key=key-1p6xztqwntxihuxv914d mode=list] Synchronization is creating quite a stir in the mobile backhaul industry as operators are wrestling with a variety of synchronization technology options including Synchronous Ethernet (SyncE) and Precision...
