be integrated into Echelon’s smart meters to enable the com- munication between the smart meters and the back-haul utility. Since T-Mobile’s GSM network will handle all the communi- cation requirements of the smart metering network, there is no need for an investment of a new dedicated communications net- work by utilities. Telenor, Telecom Italia, China Mobile, Voda- fone have also agreed to put their GSM network into service for data flow of smart metering communications. Itron’s SEN- ITEL electricity meter is integrated with a GPRS module and communicates with a server running SmartSynch’s Transaction Management System. Code-division multiple-access (CDMA), wideband code-division multiple-access (WCDMA), and Uni- versal Mobile Telecommunications System (UMTS) wireless technologies are also used in smart grid projects. A CDMA smart grid solution for the residential utility market has been introduced by Verizon, and Verizon’s 3G CDMA network will be used as the backbone of the smart grid communications with the SmartSynch smart grid solutions [37]. UMTS is IP-based and a packet oriented service that is suitable for metering appli- cations [37] Telenor with Cinclus technology is offering UMTS technology for smart grid communications [37]. An Australian energy delivery company, SP AusNet, is building a dedicated communications network for smart grid applications and chose WiMAX technology for the commu- nications need of the smart meters. WiMAX chip sets are embedded into the smart meters and wireless communications is dedicated between smart meters and the central system in SP AusNet’s system. A U.S. wireless carrier, Sprint Nextel, had signed a partnership with the smart grid software provider, Grid Net, on a project to provide communication between smart meters and smart routers over its 4G wireless network. General Electric (GE) is developing WiMAX-based smart meters with CenterPoint Energy and had collaborated with Grid Net, Motorola, and Intel to focus on WiMAX connectivity solutions. In GE’s smart meter project with CenterPoint En- ergy, it will deploy WiMAX-based MDS Mercury 3650 radios to connect the utility’s back-haul system to collection points, which will collect data from smart meters that are installed by CenterPoint [37]. Furthermore, some major companies, such as Cisco, Silver Springs Network, and Verizon, also implement WiMAX smart grid applications. The world’s largest WiMAX vendor, Alvarion, has announced its partnership with a U.S. utility company, National Grid, for a WiMAX-based smart grid project. Lower deployment and operating costs, proper security protocols, smooth communications, high data speeds (up to 75 Mb/s), an appropriate amount of bandwidth and scalability are the advantages of today’s WiMAX technology.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
