Zayo Group Holdings, Inc. is expanding its fiber infrastructure in Ohio, making significant investments in metro network to support enterprise and mobile carrier customers driven by an anchor customer deal. The network expansion will further strengthen Zayo's dense Ohio metro networks and add nearly 300 new route miles in the Youngstown and Akron area.

Zayo's existing network provides long haul connectivity throughout the state, including the Cleveland/Akron/Pittsburgh corridor. This build will also enable additional diverse options through Youngstown.

The expansion illustrates a trend toward densification of Tier 2 and 3 markets and diverse connectivity between them. The growth of bandwidth intensive content, OTT streaming services, and IoT applications is leading companies to deploy services at the edge of the network. Further densification will be required for 5G.

The expanded network will provide healthcare, universities, local government, data centers and enterprises in Youngstown and Akron with wavelength and other fiber-based solutions along the route. Construction on the project will start this quarter and is anticipated to be completed in 2020.

Accuver has launched commercial field testing and data analysis tools for Samsung S10 5G smartphones.

Accuver provides a laptop-based tool (XCAL-M) and a handheld tool (XCAL-Solo) to give customers the full flexibility to conduct their testing. XCAL-M supports testing with four devices (LTE and 5G) and one network scanner, making it versatile for multi-device drive testing. XCAL-Solo supports one device and one network scanner, and it is designed for walk testing which is especially important for mmWave networks.

Both XCAL-M and XCAL-Solo tools support the following features:

- Samsung S10 5G smartphone with Qualcomm X50 chipset and with Samsung Exynos chipset - Dual chipset interface (LTE + 5G), enabling users to see LTE and 5G NR KPIs (including L1 throughput and PDCP throughput) and messages simultaneously in real time - Beamforming measurement analysis

- 3GPP Release 15 specifications from June, September, and December 2018

- Network scanner for FR1 and FR2 bands from PCTel (IBflex & HBflex) and Rohde & Schwarz (TSME6 & TSMA6)

- Rich 5G NR KPI information

Accuver also provides XCAP-M data analysis software that allows users to do detailed analyses, troubleshooting, and reporting of the 5G NR data collected with Samsung S10 5G. XCAP-M also supports QXDM logs, and it features correlation analysis between 4G and 5G by synchronizing time. XCAP-M presents a comprehensive view of 5G network/device performance through maps, tables, graphs, 5G NR signaling, L3 and packet messages, and beamforming KPIs. Some KPIs in L1 and L2 can even be analyzed per TTI level. Some examples of the KPIs presented by XCAP-M are as follows:

- Serving Cell Beam Mgmt. - MAC BRS Report - ML1 Searcher Init Acquisition - ML1 Searcher Measurement - Tx Power Control Info - MAC LL1 CSF Info / RSRP - MAC RACH MSG1 ~ MSG4 - MAC PD(U)SCH Info - PDCCH DCI Format Info - PD(U)SCH BLER Info - L1 & L2 Throughput - RLC & PDCP Statistics Summary - RRC / NAS Signaling Analysis
