COFDM umyalezo wireless umgama omde transmission kumgama Real – nenkqubo yokuhambisa ixesha

umyalezo wireless COFDM

umyalezo COFDM esingenangcingo transmission umgama omde umgama

 

 

eziluncedo System

 

1. transmission umgama omde umgama

2. inkqubo yokudlulisela Real-ixesha

3. Ukulibaziseka kwexesha elifutshane kakhulu ngaphantsi kwe 500ms

4. quality umfanekiso ogqibeleleyo, imibala eqaqambileyo nomfanekiso emlungisa

 

Iimbonakalo

 

1. Zokuhambisa umbane 1w

2. Kakhulu ayisindi nezindlu namaxethuka

3. lokungcangcazela, ukumelana nempembelelo

4. Ukusebenza COFDM kwezwi, MPEG-2 / H.264 JPEG

5. ubungakanani omncinane, 102 × kuphela 60 × 21.5 mm

6. isicelo Perfect mobile

7. transmission Video ekumgangatho ophezulu, akukho mosaic, yayingengommangaliso donsa

8. Inkxaso non-line-of-emehlweni ukudluliselwa, wokuvavanya ngamandla umgca;
