Emergency Services Mobile Networks
Whitepaper by GL Communications Inc.
In responding to emergency situations, clear communication between personnel is mandatory. Poor voice quality and long latency can lead to miscommunication resulting in catastrophic consequences such as loss of life and damage to critical infrastructure.
"Direct Access" to Channels on Multiplexed OC-12/STM-4, OC-3/STM-1, and T3/E3
Whitepaper by GL Communications Inc.
– A Unique and Cost-Effective Approach
Tap the fiber stream, de-multiplex the stream using just a combination of firmware/software - greatly minimizing all the hardware, wiring, power, and space requirements. With this approach on higher optical rates, such as OC-12 or STM-4 (622 Mbps), the aforementioned savings that can be achieved are tremendous!
Testing ATAs, Gateways, VoIP PBXs, and other Signal Processing Elements in VoIP Networks
Whitepaper by GL Communications Inc.
IP networks contain a myriad of signal processing devices including gateways, analog telephone adapters (ATA), and VoIP PBXs. Testing these signal processing elements requires powerful and versatile tools to not only simulate various network conditions but also to accurately measure the resulting output performance.
Mobile Networks Satellite Backhaul - Issues, Test Tools + Requirements
Whitepaper by GL Communications Inc.
The future is equally optimistic for SATCOM. The scope of this article, however is more modest, to take a look at some of the current trends in satellite communications applications, testing, and test tools.

Voice is no longer the money-spinner. But yet critical for survival.
Editorial Report by RCR Wireless – GL CO-SPONSORED
This exclusive report outlines the advances in LTE-IMS networks, and the need for operators to step up their testing, assessing and monitoring of voice along with data traffic.
The Rapidly Evolving Submarine Cable Market
Editorial Report by Lightwave – GL CO-SPONSORED
The submarine network market is exploding. While undersea network requirements differ in some ways from those of terrestrial networks, many of the market drivers are similar. This Editorial Guide describes why the market is so vibrant, examines wholesale pricing trends, and looks at new ways to control submarine network performance.
Eye on the Metro Networks
Editorial Report by Lightwave – GL CO-SPONSORED
Metro networks are seeing unprecedented traffic growth. That means changes in the requirements and applications where optical transport systems play a role. As operators look to increase their per-wavelength capabilities to 100 Gbps and beyond, flexibility, scale, and fast service roll out will prove paramount. These articles review the technologies that can meet such requirements.
Optical Access Strategies for MSOs
Editorial Report by Lightwave – GL SPONSORED
Even with ongoing work on advances such as DOCSIS 3.1, fiber will become even more critical for cable operators as bandwidth demands grow. These article highlights potential future pathways.
The path to 5G : Smooth sailing or speed bumps along the way - VoLTE, 4.5G
Editorial Report by RCR Wireless – GL CO-SPONSORED
This next phase of LTE covers Releases 12 through 14. Release 15 marks the start of 5G work within the 3GPP and does not fall under the LTE naming discussion. There are eight initiatives that have been identified as being requirements for 5G. These include ….
Small cell testing: Carrier aggregation, interference, EICIC and QoE
Editorial Report by RCR Wireless – GL CO-SPONSORED
As small cells continue to make more progress in enterprise and outdoor public use, their interactions with the macro network, features, functionality and cost of testing are coming into sharper focus.
The Future Evolution of LTE
Complimentary Tutorial by IEEE, Sponsored By GL Communications Inc.
This tutorial will discuss the following questions: To what extent will LTE evolve before 5G takes over, or will LTE be the dominant over-arching radio access technology hosting 5G access?
