Frequency sang tak vs. Ultra-Frequency sang ber?

HF vs. UHF RFID: A dik thlan dan tur

RFID tech hi chi hrang hrang a awm a, a tam ber pahnih chu 1000 a ni.Frequency sang (HF) 1.1.lehUltra-a tam ber (UHF) a ni.. An thawk dan a inang lo va, an man a inang lo va, thil hrang hrang atan an hmang bawk. Thil dik lo thlan hian hun leh sum a khawhral thei a ni.

1. Eng nge a danglamna?

A tam zawk (HF) – 13.56 MHz

Zau zawng:Short (inches tlemte atanga feet khat vel).

A tha ber chu:secure, close-Up tasks.

hman a ni:Access card (office badges), contactless payment (apple pay, credit card), library lehkhabu te.

Pros:Liquids leh metal bulah hna a thawk tha zawk a, encryption a support a, khawvel pumah a awm bawk.

Cons:Scan hnaih a ngai a ni.

Ultra- a tam ber (UHF) – 860-960 mh a ni.z

Zau zawng:Long (feet engemaw zat atanga feet 20 aia sang).

A tha ber chu:Fast, bulk scanning a ni.

hman a ni:Inventory tracking (retail, warehouses), thawn chhuah pallet, hmanrua tracking te a awm bawk.

Pros:Vawi khatah tag tam tak a chhiar a, tag man tlawm zawk, long range.

Cons:Metal emaw liquid emaw bulah a thawk tha lo a, a him lo zawk, frequency rules pawh ram hrang hrangah a inang lo.

2. Eng ber nge i hman tur?

HF tih kha thlang la, a nih chuan:
✔ Security (pawisa pek emaw access control ang chi) i mamawh a ni.
✔ Liquid emaw metal emaw bulah thil i tagging a.
✔ Khawvel pum huapa hman theih tur system i duh.

Entirna:RFID loyalty card hmanga coffee dawr pakhat-Customers te chu tap leh go mai mai.

UHF tih kha thlang la, hetiang hi a ni ang:
✔ Hmun hla tak atanga scan a ngai.
✔ Item tam tak i track nghal vat a (warehouse ang maiin).
✔ Tag man tlawm ber ber i mamawh.

Entirna:Thil zawrh dawr pakhat chuan vawi khatah thil za tam tak a scan-UHF chuan second tlemte chhungin a ti thin.

3. Harsatna awm fo .

Metal & Liquids te:UHF signals te chu anmahniin an ti buai thin. HF hian a handle tha zawk.

Ram dan tur:UHF frequency a inang lo (eg, US vs. Europe). HF hian hmun tinah hna a thawk ve tho.

Tag inrawlhna:UHF hian vawi khatah tag tam tak a scan thei a, mahse a chang chuan an inzawm khawm thin.

4. Thutlukna hnuhnung ber .

HF=khar{{1}up, him, rintlak.(Payment, ID card, tracking te te).

UHF=a sei-Range, bulk scanning, a man tlawm.(Warehouse, retail, inventory lian tak tak te).

A la chiang lo em ni? Zawt:

Scan hla leh rang a ngai em? → UHF a ni.

Security mamawh emaw Metal/Liquid bula hnathawh emaw? → Hf.

System thenkhat phei chuan an hmang ve ve a, mahse chu chu a buaithlak zawk. Keep it simple-I mamawh ang chiah kha pick rawh.
