Nws yog qhov nyuaj rau overestimate qhov txiaj ntsig tseem ceeb ntawm kev sib txuas lus tshiab (3g) - cov ntaub ntawv hloov ceev. Nws muaj peev xwm mus txog 7 Mbps. Txawm li cas los xij, hmoov tsis, qhov kev ceev no tsuas yog muaj rau cov neeg uas nyob ze ntawm lub hauv paus chaw nres tsheb, thiab cov so tau yuam kom muaj cov ncauj lus nrog cov kilobytes ntawm cov tsheb thauj khoom hauv Internet tau tawm uas siv GPRS / EDGE. Txhawm rau kom nce qhov ceev ntawm 3G modem, tus kav hlau txais xov sab nraud yog siv, uas koj tuaj yeem ua rau koj tus kheej.
Nws yog qhov tsim nyog
- - cov kav hlau txais xov tuab;
- - phaj hlau;
- - ntawv ci;
- - tooj liab hlau;
- - txuas;
- - soldering hlau;
- - tus pas ntsuas;
- - cim cim;
- - laum;
- - foob;
- - cap los ntawm hairspray.
Cov Lus Qhia
Kauj ruam 1
Khoov cov hlau: nws yuav tsum ua ob lub fab nrog ob sab ntawm 53 mm. Tom qab ntawv ncab cov plaub fab me ntsis, ua rhombuses tawm ntawm lawv, ob lub kaum ntse ntse uas yuav tsum muaj 120 degrees.
Kauj ruam 2
Sawb cov hlau npaj (tom qab lub txuas raug muab tso rau ntawm cov hlau, nws txoj kev tiv thaiv yuav tsum tiv thaiv lwm centimeter). Tom qab ntawd cam ib feem ntawm cov hlau mus rau txuas lub cev: koj yuav tsum tau txais "ntsaws".
Kauj ruam 3
Solder lub "ntsaws" rau lub kav hlau txais xov. Txawm li cas los xij, txhawm rau txhawm rau txuas lub zog ntawm cov kav hlau txais xov rau 3G modem, qhov khoom siv no yuav tsum tau nruab nrog lub ntsej muag tsom. Ib lub phaj hlau ua los ntawm PCB lossis plywood qhwv hauv ntawv ci tuaj yeem siv ua kev cuam tshuam.
Kauj ruam 4
Qhov ntsuas tsom yuav tsum muaj qhov ntev: 120 x 135 millimeters. Kos tus cim hlau phaj thiab txiav tawm. Tho qhov nyob hauv nruab nrab ntawm qhov reflector: txoj kab uas hla ntawm lub qhov yuav tsum sib npaug zos rau cov tuab ntawm cov hlau siv thaum siv.
Kauj ruam 5
Qhov kev ncua deb ntawm tus kav hlau txais xov thiab lub duab hluav taws xob yuav tsum yog 36 millimeters. Hauv qhov no, ib lub hau plaub hau yog qhov zoo heev: ua grooves hauv nws, ntxig rau cov xaim thiab ruaj ntseg nws.
Kauj ruam 6
Yog li hais tias tus qauv koj ua tsis poob sib nrug, kho txhua yam nws cov pob qij txha nrog silicone. Tom qab ntawd qhwv ntawm 3g modem nrog nruab nrab xaim (ua plaub mus rau tsib lem), thiab muab cov ntawv ci rau ntawm tus thib ob. Tom qab koj sib sau ua ke kav hlau txais xov hauv tsev, nrhiav ib qho chaw muaj teeb liab zoo tshaj plaws thiab teeb tsa koj cov kev tsim muaj.
