Initially, wireless carriers deployed 4G/LTE solely for data use. Without VoLTE9-1-1 capabilities, carriers must process emergency calls over 3G networks (circuit-switched fallback), even in areas where LTE is deployed. However, with TCS’ VoLTE9-1-1 service, they can now process 911 calls in an all-LTE environment, enabling them to reclaim or reuse 3G spectrum.

“As carriers increasingly move toward LTE networks, the ability to handle 911 emergency communications is critical,” said Thomas Ginter of TCS. “By leveraging VoLTE9-1-1, network operators are helping to ensure subscribers receive the responsiveness they need in an emergency situation, while expanding coverage to areas where 3G coverage is lacking.”

TCS VoLTE9-1-1 features:

• Call routing to the PSAP: The TCS VoLTE9-1-1 service routes a 4G/LTE-originated 911 call using coarse location via the route determination function component.
• PSAP telecommunicators can call back if disconnected: The TCS VoLTE9-1-1 service remains fully backwards compatible, supporting necessary functions such as providing PSAPs with full 10-digit subscriber callback numbers.
• Re-bid by a PSAP for precise location after call routing: The location retrieval function allows a wireless carrier complete flexibility in choosing its underlying high-accuracy location technology and supports updated/precise position requests.
• Emergency voice call continuity for location service: Location continuity and location delivery to the PSAPs are supported in usage scenarios where the 911 call switches from 4G/LTE to 3G/2G networks.
• Expansion beyond voice: As wireless networks advance, multimedia objects such as text, audio and video can be transferred to a compatible termination point with LTE IP networks, for example, an NG ESINet and i3 PSAP. Leveraging an all-IP network makes it easier and more cost effective to interconnect services.
• Small cell support: The TCS VoLTE9-1-1 solution supports small cells, including femtocells, microcells, and picocells, which are now commonly used in dense urban, indoor areas and enterprise networks.

TCS supports half of all U.S. wireless E911 calls, serving more than 140 million wireless and IP-enabled devices.  The company holds more than 280 patents, 43 of which relate to public safety, and more than 360 pending worldwide.

The Synchronized ECC approach involves over-the-air transfer of measured data between the test platform and a mobile device in a synchronized fashion. This method, proposed by a leading U.S. wireless carrier, does not require any overhead or user interaction to calculate the ECC, making it easier and faster to execute test versus other approaches. 7Layers test engineers used the Rohde & Schwarz TS8991 OTA Performance Test System and software option R&S AMS32-K30 as a test platform for validation.

“”7Layers is excited to help bring an ecosystem of vendors together to advance testing of LTE enabled devices utilizing MIMO,”” commented Mahesh Kodukula, business development manager of 7Layers. “”As an accredited test laboratory, we provided a realistic test environment for our partners.””

“”We are pleased to enable this type of testing on our R&S TS8991 OTA test platform and to offer this functionality to a variety of customers that have been waiting for this feature,”” said Thorsten Hertel, OTA product specialist at Rohde & Schwarz. “”We strive to meet the industry needs of the leading edge development of LTE devices.””

Adapted from a Mercedes Benz Sprinter van, this unique measurement vehicle has been delivered to ESTEC by Austria’s Joanneum Research institute. “This is a dual-purpose vehicle, suitable for both telecommunications and navigation system testing,” explained Simon Johns of ESA’s Radionavigation Systems and Techniques Section.

“For navigation, we have the Galileo constellation coming on stream, as well as the stepping up of ESA’s GNSS Evolution programme — designing what comes next after Galileo’s first generation.”

The four wheel-drive vehicle can host a three-person team, and is crammed with dedicated navigation and telecommunication monitoring equipment.

“One of the main goals driving the design was to have an ‘easy to adapt’ test platform suitable to set up test campaigns for different mobile satellite systems and standards that would require different types of antennas and specific receiver/transmit equipment,” explained Olivier Smeyers of ESA’s Communication-TT&C Systems and Techniques Section.

“On the telecommunications side, there is a continuous effort to enhance current and create new mobile satellite-based broadcast and interactive services via the evolution of current systems or developing new standards,” Smeyers said. “Testing in the field is an essential element for validating and eventually establishing evolved or new standards. The vehicle has built-in multimedia equipment, including storage and control computers, multimedia gateway, passenger LCD screens, cameras and microphones, to serve this purpose.”

The vehicle’s 8-meter-high telescopic mast.

The vehicle features include two removable roof plates to mount specialized antennas (one currently hosts the antenna of a Broadband Global Area Network satellite terminal for Internet connectivity and multimedia and data streaming), an 8-meter-high telescopic mast capable of carrying 25 kilograms, a rubidium atomic clock synchronized to GPS time with nanosecond accuracy, a high-end spectrum analyzer and oscilloscope for signal measurements, and mobile temperature sensors to monitor the rack equipment.

A fish-eye video camera incorporating onscreen GPS timing and positioning performs continuous recording of its surroundings — to throw light on high buildings, trees, or other factors that might affect results.

Internal and external generators yield up to 5 kilowatts to keep everything running — sufficient power to supply two typical European households.

“The challenge was to fit in all the equipment and provide the necessary power and air conditioning, while still weighing less than 3.5 tonnes,” said Thomas Prechtl of Joanneum Research. “Exceeding this weight would have meant drivers would have needed a special license, and potentially limited its operations in some European nations.”

The new devices integrate a multiband CMOS RF transceiver with GPS and full-time sniffing capability while maintaining software compatibility with all previous Broadcom WCDMA physical layer and backhauling interface architectures.

With the new chips, mobile operator OEMs and ODMs have a powerful, low-cost, power efficient device to support small cell strategies and meet growing mobile traffic demands. Embedding a high-speed CPU and Broadcom’s Layer 1 modem and peripherals, these devices provide a complete low-power single-chip solution for residential and small enterprise 3G small cell deployments, the company said.

“As on-the-go content consumption continues to drive traffic growth, mobile operators must meet consumers’ increasing demand for higher bandwidth without sacrificing quality of service,” said Greg Fischer, Broadcom’s vice president and general manager for Broadband Carrier Access. “Broadcom’s BCM61630 SoCs deliver a low-power, cost-efficient device for residential small cells to leverage existing mobile infrastructure and deliver faster data speeds through a smaller form factor.”

The rapid growth of mobile data services, driven by smartphones, laptops, and tablets has accelerated data-traffic growth to the point where macro cellular networks are no longer sufficient to meet subscriber demand in many high-density indoor and outdoor settings. While new macro cellular technology, such as long-term evolution (LTE), is being introduced to address this capacity crunch, it will provide only partial relief, as traffic volumes continue to grow faster than operators can economically add capacity, Ruckus said.

Consequently, mobile operators are rapidly adopting Wi-Fi as an additional radio access network (RAN) option to augment mobile capacity. At the same time, fixed line carriers and multiple system operators (MSOs) are also deploying Wi-Fi for public access to enhance their service offerings, reduce subscriber churn and enter new markets such as managed enterprise wireless LAN (WLAN) services.

For high-capacity outdoor environments, such as stadiums and other public venues, the Ruckus ZoneFlex 7782 outdoor AP Series is a family of four new, high-capacity Wi-Fi access points designed to give service providers unprecedented capacity and performance. With models supporting omni-directional antennas, 120º sectorized, and 30×30º narrow-beam coverage through integrated internal antennas as well as external antenna options, ZoneFlex 7782 APs offer a combination of high performance and flexibility in a sleek, low profile, light form factor essential for meeting the tight mechanical and aesthetic constraints of deployment outdoors, Ruckus said.

Each Ruckus ZoneFlex 7982 AP is a dual-band, three stream (3×3:3) 802.11n access point enabled for high throughput approaching 900 Mbps. ZoneFlex 7782 APs with integrated antennas support Ruckus-patented BeamFlex adaptive antenna technology for greater signal gain and interference mitigation. Additionally, the Ruckus ZoneFlex 7782 family integrates a GPS receiver, allowing service providers to begin providing location-based services as well as continuous spectrum monitoring features.

The Smart Grid has brought about power technology advancements that fundamentally change substation operations. Power equipment and their data networks are shifting from simple, reactive control and reporting to proactive, real-time management and operations control, making advanced synchronization and timing more critical than ever, according to Symmetricom. The SGC-1500 Smart Grid Clock is designed to address this need, enabling power equipment to operate more efficiently and closer to its operational limits. For example, one microsecond accuracy is required by the phasor measurement unit (PMU) for real-time network situational awareness and overall operational efficiency. Without accurate time stamps, PMU data has limited value. For power utility companies, that translates into enhanced network utilization rates as well as smarter management and mixing of renewable and traditional power sources.

“Power and utility companies are increasingly looking to source the latest technology innovations in order to modernize their infrastructure,” said Greg Neichin, executive vice president, Cleantech Group. “Over the past three years, we have tracked more than $700 million in venture investment committed to companies developing smart grid products. These are all data-intensive applications that will rely heavily on precise timing and synchronization, as well as more advanced analytics to process these vast streams of new information.”

“The Smart Grid architecture and related standards require a new approach to timing distribution across the overall network,” said Manish Gupta, vice president of marketing and business development for Symmetricom. “Symmetricom brings extensive experience in delivering precise time to the communications, government, and enterprise markets. Serving the power utility telecom network over the past 10 years, Symmetricom is ideally positioned to meet the emerging timing requirements of the Smart Grid.”

The SyncServer SGC-1500 meets key requirements of Smart Grid substations, including:

• Microsecond accuracy and resiliency — referencing GPS satellite signals, the Symmetricom Smart Grid Clock distributes timing with microsecond accuracy over the local area network (LAN) using the IEEE 1588 v2 Precision Time Protocol (PTP) Power Profile or IRIG-B time code.
• IEC 61850 — the International Electrotechnical Commission’s (IEC) standards for the design of electrical substation automation, which requires microsecond timing to identify and mitigate a potential fault condition in real time. This standard also identifies important electrical hardening requirements for substation environments.
• NERC CIP ― the North American Electric Reliability Corporation (NERC) reliability and security standards for Critical Infrastructure Protection (CIP), which calls for high strength security protocols.

The SyncServer SGC-1500 comes with additional industry leading capabilities such as a built-in IEEE 1588 v2 Telecom Profile input option. This enables the Smart Grid Clock to derive time from the communications wide area network (WAN), thus eliminating the need to have GPS at every substation and PMU. The Rubidium atomic clock option offers holdover capability in the event of GPS disruption. These options result in a highly cost effective and resilient solution for power utilities.
