Tez-tez so'raladigan savollar
deyarli 14 Vatt iste'mol.
1Vt 1 km masofa uchun etarli. Lekin biz siz uchun eng yaxshi qabul qilish ko'rsatkichini ta'minlash uchun 2W qilamiz.
Bu sizning mahalliy muhitingizga ham bog'liq, u LOS yoki NLOS bo'ladimi, Iltimos, sinov videomizni tekshiring, ko'p qavatlar va binolar mavjud.
Taxminan turli quvvat kuchaytirgichlarini o'zgartirish uchun 500 MVt, 1 Watt, 2 Watt, yoki 10 vatt. Bu shunchaki dasturiy ta'minotdagi sozlamalarni sozlash emas, Shuningdek, transmitter ichidagi quvvat kuchaytirgich uskunasini o'zgartirishingiz kerak. U oddiy oxirgi foydalanuvchida ishlay olmaydi va o'zgarmaydi, va xarajat va uzatuvchi metall quti o'lchami boshqacha.
Standart chastota sozlamalari 503 MGts, 509 MGts, 521 MGts, va 521 Tanlash uchun MHz, kabinetdagi bitta tugma o'zgarishi mumkin. Agar sizga haqiqatan ham faqat 1,3 gigagertsli diapazon kerak bo'lsa, boshqa modelni tanlashingiz kerak (1.2G yoki 1,4G). Iltimos, bizga talabingizning tafsilotlarini ayting.
