Hw des it wrk? wer in Suth Africa perates at 220-240Vlt and at a frequency f 50Hz. The plarity f the pwer des a cmplete change at a rate f 50 cycles per secnd. The device mdulates the thernet packets nt the 50Hz pwer line at a rate f 4.3-20.9Mhz. That is a rate f 4.3M-20.9 Millin changes per secnd. The frequency is s high t eliminate interference frm ther electrical devices. I.e. Laser printers r welding machines.
Standards Hmelug is an industry trade grup that cnsist f abut 50 cmpanies that define the standards fr pwer line cmmunicatins. Hmelug 1.0 Released June 2001. Specificatin fr cnnecting devices via pwer lines. Theretical speed f 14Mbits/s Hmelug 1.0 Turb. Unfficial specificatin. Theretical speed f 85Mbits/s. Hmelug AV Released December 2005. Designed fr transmitting HDTV and VI. Theretical speed f 200Mbits/s. Nt backward cmpatible. Can c-exist n same netwrk.
Standards cntinued Hmelug Access BL Under develpment. A wrking grup t develp a specificatin fr the t-thehme cnnectin. (Last mile) Hmelug Cmmand & Cntrl Released 9 Octber 07 Lw speed, lw cst technlgy cmmunicatin. The specificatin enable advanced, whle-huse cntrl f lighting, appliances, climate cntrl, security and ther devices.
Interperability The alliance certifies prducts fr Hmelug cmpliance. Devices marked with the certificatin mark will interperate with each ther. Hwever, they will nt wrk with prprietary pwerline technlgies frm anasnic r UA (aka DS2) which bth ffer similar speeds. Hmelug is participating in develping I 1901 standard tgether with many thers and particularly its cmpetitrs anasnic and UA. This leave gd chances t have an unified pwer line cmunicatin standard in the future. CCA is an assciatin wrking t define a specificatin t allw incmpatible technlgies t cexist n the same pwerline. CCA is als participating in develping I 1901 standard.
Security All devices cmes with a default passwrd that allws units t be cnnected t the netwrk with ut f the bx cnvenience. ach unit has a unique MAC address. T change the passwrd yu cnnect remtely t the unit via the Mac address. Multiple unit passwrds can be changed at the same time. Data n pwer lines are encrypted. Only units with the same passwrd will be able t de-encrypt the data. Mre than ne passwrd netwrk can c-exist n the same pwer line.
