salam, dulu perkara ni pernah timbul, then ilang bersama angin.

Tiba2 semalam aku layan lak Remaja kat tv3, Gadget segment. abg brader tu tunjak la device cucuk kat letrik port (3 pin tu), kt bwh dia ade pot rj45 (klu xsilap), port networking komputer tu. so, aku usha la device tu kt net, tp xjumpa.

so, wujud ke bende tu. aku jumpa ni je http://gadgets.fosfor.se/network-your-electric-wires/ , aku igt smlm aku tgk kaler putih, bukan brand ni.

ermm..byk kali gak dgar project data transfer pki transmision line...mende ni rasenye ok ke x kalo pki dirumah..huhu

basically bile sine wave utk electricity diubah kepada digital / pulse wave..potensi utk harmonic distortion amat tinggi n byk gak kekurangan nyer..bile lalu kat transformer ia akan cepat panas so equipment nye lifespan pon kurang..kene ganti la selalu...

mmg bleh...tp nk convert jdik pulse wave dari sine wave melibatkan komponen electronik yg byk gak la...so lgik byk non linear load = high harmonic..

susah gak..sbb senang dissipate la signal dia.. trasnmission line tak bagus tuk transmit data yang high freq dan byk2 data...

nape plak frust? katakanlah streamyx cuma 1.0 mbps.
network speed yang aztech homeplug ni generate ialah 85mbps utk LAN kabel dan
wirelessnya pulak ialah 11b dan 11g iaitu 11mbps utk 11b dan 54mbps utk 11g.

manakala download file besar, transfer rate dari rapidshare contohnya, max speed yg biasa dapat ialah 170kbps.
maknanya  your download speed is 170 KB/s (0.17 MB/s). tak sampai suku dari 1.0 mbps (1000kbps) yg kita langgan dgn streamyx tu.

okey, kalo transfer file dari pc ke pc (andaikan ada 2-3 pc di 1 rumah yg guna homeplug).
1 file movie 700mb, transfer dari pc A ke pc B mengguna wireless 11g, iaitu 54mbps (max speed).
biasanya kalo wireless transfer aku leh dpt 36mbps-48mbps dan 1 file muvie 700mb leh di pindahkan dari pc-A ke pc-B dlm tempoh 2minit-3minit.

dah ade research utk powerline communications (PLC) ni kat m'sia...

tp x blh nak jln sbb melibatkan 2 company 'gajah' yg berbeza background... TNB & TM...

so... berkubur ler jawbnye...

sekadar utk home network or small business network masih blh jln... solution pon lebih murah sbb guna powerline yg sedia ada jer...
