Syniverse has agreed to purchase Aicent for $290 million, which is expected to increase Syniverse's network and its analytics capabilities.
Aicent is the largest multi-service IPX provider for data network services and serves the world's 10 largest carriers and more than 200 mobile operators globally, as well...
Backhaul for mobile networks is a critical piece of network operations to ensure capacity and speed, as it relates to the transport of data from distributed network sites to the network core. RCR Wireless News has assembled a variety of resources on aspects of...
Long Term Evolution is expected to step up wireless networks’ ability to handle increased demand for capacity and make networks more efficient. But once releases reach LTE-Advanced, the possibilities for smarter traffic increase, and LTE topology promises to change how carriers design their networks by...
As mobile networks have evolved over time to an all-IP architecture, Carrier Ethernet has become an important standard for data transport and interfaces.
The technology is widely used in telecom networks. TW Telecom isthe third-largest U.S. provider of Carrier Ethernet services.
Mike Rouleau, senior vice president...
As wireless network capacity demands skyrocket, carriers are using WLAN (wireless local area network) or Wi-Fi technology to offload traffic. As those networks evolve toward more extensive LTE deployments, Wi-Fi is trying to keep pace by moving to next-generation services in order to provide...
Expectations are high for the needs of LTE backhaul: high capacity, high speed, and high quality of service. Providers are building out their new LTE networks at a fast pace, necessitating investments in LTE backhaul as those networks are turned on across the country.
LTE...
Backhaul is often spoken of as critical to telecom networks – but what is it? Which part of the mobile network is considered the “backhaul” network, and what does it do? We asked network experts to give us their backhaul network definitions.
Glen Hunt, principal...
The Best LTE Network Architecture Diagrams
Wireless operators are rapidly expanding their LTE networks to take advantage of additional efficiency, lower latency and the ability to handle ever-increasing data traffic. RCR Wireless presents a collection of LTE network architecture diagrams.
This diagram from standards body 3GPP shows...
More than 1 in 5 IT professionals expect to deploy software-defined networking this year, and about one-third are expecting deployments by 2015, according to the seventh annual State of the Network report from Network Instruments.
The report says that there is "a strategic shift in how...
Wireless carriers are scrambling to acquire and free up new spectrum resources in an attempt to feed consumer desire for mobile data services. This quest for spectrum along with the deployment of more efficient LTE services could meet those short-term needs, but a recent...
DAS contracts increase in size, outpacing market growth
Typical distributed antenna system contracts for hardware only (hubs, nodes, remote radio heads, antennas, etc.) now range from $5 million to $10 million, compared to just $1 million a few years ago, according to analyst Stéphan Téral...
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...
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...
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,...
It's a country ahead of the curve in many areas, but wireless innovation is not one of them. But don't count them out just yet. One high-profile Thailand mobile operator is right on the cusp of launching Long Term Evolution (LTE), as promised. What...
LTE LTE LTE! It's all we've been talking about. But as mentioned in previous articles, it is important to appreciate our past, GSM specifically. One integral part of the GSM network is the GPRS (General Packet Radio Service), a non-voice service added to existing TDMA networks,...
With the continued massive rollout of Long Term Evolution (LTE) and more and more operators becoming obsessed with staying up to date, the issues of limited spectrum remains. Multi-layer heterogeneous network layout including small cell base stations are key for further enhancements of the...
Today, there actually are not many questions when it comes to the HSPA LTE debacle. The answer is clear, Long Term Evolution (LTE) is the future. Upgrading to LTE technology is part of the natural upgrade process. But, how do they differ? Let's dig...
The LTE attach procedure call flow is a subject that may seem hard to understand. So let's break it down. How does the LTE attach procedure call flow work?
Well first, the UE needs to register with the network to receive services that require registration. This registration...
Like any other wireless network, LTE (long term evolution) is only as good as its components. This means delivery of services is extremely important. This is now achieved with LTE MBMS (multimedia broadcast multicast services). LTE MBMS is a point-to-multipoint interface that delivers broadcast...
We talk over and over again about the complex Long Term Evolution (LTE) and its many components. One of these components, known as the non-access stratum (NAS), is highest stratum of the control plane between user experience (UE) and Mobility Management Entity (MME) at the radio...
