Long term evolution (LTE) is the standard for today's wireless networks, and replaces third generation (3G) technology. LTE technology is a based on a 3GPP standard that provides for a downlink speed of up to 150 megabits per second (Mbps) and an uplink speed of up...
Why T1 testing necessary? Let's take a closer look at how carriers test their T1 networks and more important, what T1 test equipment they use.
T1 or DS1, as a standard, has been around since the 1960’s and has evolved from a way to carry multiple voice...
Once a wireless phenomenon, Bluetooth is part of our everyday lives. Whether you utilize it to talk on the phone in your car or you've mistakenly thought someone was addressing you at the grocery store only to see that little device in their ear,...
In today's test and measurement world, many different devices and methods are necessary. For connection testing, this includes cable and antenna analyzers. Cable analyzers verify the electrical connections in a cable or other wired assembly. Cable analyzers typically consist of a source of electric current, a...
The Universal Mobile Telecommunications System (UMTS) is a third generation mobile cellular system for networks based on the GSM standard. Because of this systems prominence, and because of wireless users' network demand, UMTS testing is necessary. UMTS uses wideband code division multiple access (W-CDMA) radio access technology...
Wireless network testing is no mundane task. It involved thorough thought, procedures and most of all, high-end equipment. This equipment differs depending on the type of network that is being tested. First, let's examine the GSM (Global System for Mobile Communications) and compare a...
How Passive Intermodulation Affects Network Performance
Passive intermodulation (PIM) is a big concern for wireless providers because of the negative effect it can have on network performance. In active devices, PIM occurs when signals at two or more frequencies mix with each other in a non-linear...
Test Types and Parameters for LTE Driving Testing
LTE drive tests are an important part of how wireless carriers determine whether their networks are performing well -- and get a glimpse into their competitors' network performance. There are multiple types of LTE drive tests, as...
Until recently, PIM (Passive Intermodulation Distortion was only a concern for wireless networks, and ultimately, the wireless user. Today, cable manufacturers are involved as certain low PIM cables are necessary for maintaining and testing this annoyance and potential service inhibitor.
And even though PIM is not a...
If you're well-versed in today's wireless industry, you know Passive Intermodulation (PIM) is a big part of keeping wireless networks up and running, with the ability to meet the high data demands of today's wireless users. PIM testing, however is not cheap making the...
Passive Intermodulation (PIM) testing is no stranger to the wireless industry. In fact, it is a standard for radio site commissioning and certification. PIM's history dates back to the beginning days of radio communication and has become a major performance issue for wireless carriers...
When it comes to Long Term Evolution (LTE), it's all about the user experience and therefore, user equipment testing is extremely important. LTE is cutting edge in terms of speed and network performance, but according to Aeroflex, in any real-life mobile communications network there...
The arrival of Long Term Evolution (LTE) brought significantly different wireless network capabilities. Today's wireless user wants and expects superior service and performance. To make sure this happens, extensive and frequent network testing needs to be done. And when it comes to LTE testing,...
Passive Intermodulation (PIM) is becoming more and more important as wireless users demand data, with high speeds. It affects network speed and performance, therefore, needs to be monitored, making PIM testing a basic requirement especially today.
What is PIM?
PIM occurs when two or more high...
In the United States, Long Term Evolution (LTE) is well-established. When it comes to testing, at this point an LTE antenna test would be for maintenance only, not for initial performance. Yes, some operators are still in the process of launching widespread service, but...
The ability to test network and device features and functions is an important piece of technology development and deployment. RCR Wireless News looks weekly at the test and measurement space to see what's afoot.
--Agilent Technologies has had a busy week. The company said it...
Aeroflex Holding Corp. (NYSE: ARX) saw its net sales dip slightly year-over-year, but its profits improved as it stemmed losses from continuing operations.
Net sales edged downward to $155.5 million from $157 million in the same period of 2013. Aeroflex's net income turned around from...
Test and measurement company Ixia has released an e-book on heterogeneous network deployment, compiling strategies and lessons learned from its work over the past couple of years with vendors and operators who have deployed small cells.
"It's kinda of a collection of our input of...
-- Anritsu Corp. has received Global Certification Forum approval for three more carrier aggregation band combinations on its ME7873L. The company achieved approval by validating 80% of the Priority 1 radio frquency/radio resource management test cases in the GCF's work item 162 for new band combinations that include...
Understanding Common Sources of Interference in LTE Networks
Although many types of interference are common to all radio access technologies, the combination of new frequency allocations and new modulation types have created unique interference challenges for LTE deployments in the United States.
This webinar uses real-world...
Antenna Evolution - Meeting the Demand for LTE, Small Cell, & DAS Networks
Implementations of Small Cell and DAS systems have many challenges; not the least of which is the selection and placement of the antenna elements. Since these systems deploy antennas close to the users,...
JDSU recorded a net loss of $1.5 million for the quarter, which the company said was due to later-than-expected carrier orders. Revenues, however, were still up about 3% year-over-year to $418 million.
"Though the calendar year started off slower than expected, I am encouraged by...
