(InfoWorld) - The sun came out for EarthLink's Philadelphia Wi-Fi network on Thursday even as prospects forÂ its San Francisco projectÂ remain shrouded in fog. Wireless Philadelphia, a nonprofit group formed by the city of Philadelphia, has approved the 15-square-mile Wi-Fi test network EarthLink built, opening the door for the operator to finish building out a 135-square-mile network covering the city. The approval comes just a month afterÂ EarthLink announced it would scale back its city Wi-Fi initiative, focusing on existing and large cities for the rest of the year. The company has seven or eight cities under contract now and is negotiating with five more, Vice President of Product Strategy and Marketing Cole Reinwand said last week. It decided to stagger its Wi-Fi expansion to conserve resources, he said. Residents can already use the 15-square-mile network in Philadelphia. The full network is expected to be complete in the third quarter. EarthLink is financing, building, and managing the network and will share revenue with Wireless Philadelphia, which will offer cut-rate access for low-income people. For six months, customers of a 1MbpsÂ service will pay an introductory rate of $6.95 per month, which bumps up to $19.95 thereafter. A faster 3Mbps service is available for $9.95 for the first six months and $21.95 after that. City parks will have free access, and low-income residents can sign up for service at $9.95 per month, before promotions. Customers can also pay for service on an hourly, daily or three-day basis. The Philadelphia Wi-Fi network is notable because when announced, it set off a storm of controversy that resulted in a Pennsylvania law requiring municipalities to receive approval from incumbent telecommunications operators before building Wi-Fi networks. The law was created after incumbents complained that by financing Wi-Fi networks, cities were building networks that would compete with their businesses. The San Francisco project, which has drawn attention partly because of Google's planned involvement as provider of a free citywide service, has run into fierce opposition from activists as well as some local elected officials. The proposed contract is scheduled for a vote by the city and county's board of supervisors in July.

Cisco Systems wants to turn the enterprise data network into an electricity meter.Using open standards, the company wants to get server and storage vendors to collect and share information about their equipment and send it to Cisco routers and switches. The data could include power consumption, operating temperature and more. It&#39;s becoming a critical job, and because the network touches all IT resources across the enterprise, data collection should happen there, according to Paul Marcoux, vice president of green engineering.Marcoux joined Cisco from American Power Conversion only about six weeks ago after Cisco created the position to overlook energy issues across all parts of the company. Networking gear itself makes up a much smaller portion of IT power consumption than do servers or storage, but Cisco plans to go beyond just making its own products more efficient.Power is a growing issue in datacenters as the cost of energy rises and concerns about global climate change increase. Being able to collect and analyze information about power usage is a big part of the battle and becoming more crucial in the age of virtualization, according to Marcoux. Distributing storage and processing cycles without regard for power issues is not just inefficient, it&#39;s dangerous, he said.If virtualization software looks at a process that requires more computing power or storage space, then enlists servers or storage devices that are near to overheating or running out of power, it could send a rack of servers over the edge and shut it down, Marcoux said. For that reason, the virtualization system needs to know the power status of all the resources it may call upon, he said.By the same token, consolidated datacenters typically serve many departments of an enterprise and consume a lot of power, but those groups generally don&#39;t have to pay for their part of the power. In fact, the electricity bill often bypasses even the IT department, going to building management instead, Marcoux said. Collecting data about the power consumed by each device, and eventually by individual transactions, would allow enterprises to bill each department for the power it uses, he said.Software on routers and switches would collect the information and then take actions or forward it on to separate building management, energy management or virtualization control systems, Marcoux said. Given the large amount of energy data to be processed, Cisco may introduce daughtercards for its platforms to provide extra computing power, he said. He hopes the technology will be in place and collecting information in enterprises within three years.Because datacenters contain gear from so many vendors, open standards are the only way to make such a system work, according to Cisco. Fortunately, there already are several available standards, Marcoux said. Having standards already in place will help speed up adoption, Marcoux said.&quot;We&#39;re not trying to reinvent the wheel, we&#39;re just trying now to utilize the wheel,&quot; Marcoux said.Cisco&#39;s proposal would represent a whole new role for networks beyond communications, said Burton Group analyst Dave Passmore. Server vendors might go along with the plan, but Cisco can&#39;t count on smooth sailing, he said. Centralized power regulation would play a role in overall management of the datacenter, an area where Cisco is attempting to make inroads with other initiatives as well.&quot;Who controls virtualization in the data center is going to be the new battleground,&quot; Passmore said.
