Carriers also propose wireless solutions as direct replacement services for the existing DS0 or frame relay services. Unfortunately, the security concerns are very similar to the ones of fiber networks. Carriers also do not provide any Service Level Agreements or Quality of Service guarantees for data transmissions when utilities need the data the most: during major catastrophes when the public networks are either down or overloaded. While the carriers prepare their internal plans, only few spe- cifics have emerged. Reportedly, AT&T wants to complete the IP transition by 2020, and run more than 70 percent of its network as a software-defined network (SDN) by that time. In January, AT&T released its updated Withdrawal of Service Guide which, while not indicating a timeline, highlighted the scope of the TDM sunset activities utilities should expect. The services to be discontinued include AT&T Bandwidth Services, Local Private Line Services, One Net Services and Packet Services. AT&T doesn't even offer a replacement service for DS0, DS1 and DS3, and many of the other replacement service recommendations suffer from the defects previously mentioned: They can be prohibitively expensive, have questionable security or are not suitable for the application. In the meantime, carriers continue to raise the costs for pri- vate lines at unprecedented speed. The simultaneous reduction in the level of service and the loss of expertise in the workforce of the carriers has the potential to create severe operational difficulties for utilities. This makes the decision to plan the tran- sition for utilities even more pressing. Considering the uncer- tainties of the carriers' proposed replacement services, utilities should examine the possibility of building their own private net- works. Depending on the application, requirements, budget and location, utilities can build out their own private fiber or wireless networks. Whether utilities decide to purchase service from carriers or build their own networks, it is paramount that they start the planning process without further delay. Given the vast number of circuits at risk, this task is not insignificant. It will be a costly and resource-intensive exercise. And any replacement solutions will need to be identified quickly to assure continuity of service of SCADA, protective relaying and other mission-critical applications. On top of the technical challenges come the logistical ones since no utility employs enough workers to convert all their substation communication systems at the same time. Where fiber build outs appear uneconomical or impossible, utilities will likely rely on private wireless solutions. Connie Durcsak, UTC's President and CEO, remarked that "wireless technologies will certainly be a solution of choice for many remote areas or in cases where rights-of-way are challenging. However, the lack of available licensed spectrum prioritized for utilities and other critical infrastructure providers is a real con- cern. UTC is working with utilities and their technology partners to ensure that utilities have the information they need to weigh their options fully and to ensure that policymakers understand the impact of this situation on the nation's energy and water resources."

The SNC encourages utilities to become actively involved in this process to ensure continuity of their business operations. The ability to discuss and analyze results of monitoring devices in real time will be essential to keeping companies profitable as they cut back on emissions. Even now, the oil and gas sector is teeming with examples of applications for advanced wireless technology. Chevron has already established its own Real Time Drilling Optimization Center (RDOC) in its Houston towers. The center immerses analysts-who purposefully work the exact same 12-hour shifts as those of the rig crews-in comprehensive, real time data from the site. As more and more facilities like Chevron's RDOC crop up in the oil and gas sector, it will be imperative that wireless companies communicate with their oil and gas customers to install state-of-the- art fiber cables, routers, two-way communications, and other essential backhaul solutions to match rapidly increasing bandwidth demands.
