Me ke kūkulu ʻana i ka pūnaewele 5G, ʻoi aku ka kiʻekiʻe o ke kumu kūʻai o 5G base station, ʻoi aku ka nui o ka pilikia o ka hoʻohana ʻana i ka ikehu nui.
Ma ka hihia o Kina Mobile, no ke kākoʻo ʻana i kahi downlink kiʻekiʻe, ʻo kāna module 2.6GHz radio frequency module e pono ai 64 a me ka nui o 320 watts.
No nā kelepona 5G e kamaʻilio me ke kahua kahua, no ka mea pili lākou i ke kino o ke kanaka, pono e kiaʻi ʻia ka laina lalo o ka "radiation harm", no laila ua kaupalena ʻia ka mana hoʻouna.
Hoʻopau ka Protocol i ka mana hoʻouna kelepona ʻo 4G i ka 23dBm (0.2w) kiʻekiʻe loa.ʻOiai ʻaʻole nui loa kēia mana, ʻoi aku ka haʻahaʻa o ke alapine o ka band mainstream 4G (FDD 1800MHz), a he liʻiliʻi ka nalowale o ka lawe ʻana.ʻAʻole pilikia ka hoʻohana ʻana.
Akā ʻoi aku ka paʻakikī o ke kūlana 5G.
ʻO ka mea mua, ʻo 3.5GHz ka alapine alapine nui o 5G, kahi alapine kiʻekiʻe, ʻoi aku ka nui o ka pohō o ke ala hoʻolaha, ka hiki ʻole ke komo ʻana, nāwaliwali o ke kelepona paʻalima, a me ka mana haʻahaʻa haʻahaʻa;no laila, maʻalahi ka uplink e lilo i ka bottleneck ʻōnaehana.
ʻO ka lua, ua hoʻokumu ʻia ʻo 5G ma ke ʻano TDD, a hoʻouna ʻia ka uplink a me downlink i ka mahele manawa.Ma keʻano laulā, e hōʻoia i ka mana downlink, ʻoi aku ka liʻiliʻi o ka hāʻawi ʻana i ka uplink o ka manawa, ma kahi o 30%.I nā huaʻōlelo ʻē aʻe, ʻo kahi kelepona 5G ma TDD he 30% wale nō ka manawa e hoʻouna ai i ka ʻikepili, e hōʻemi hou ana i ka mana hoʻouna maʻamau.
Eia kekahi, maʻalahi ke ʻano hoʻolālā o 5G, a paʻakikī ka pūnaewele.
Ma ke ʻano NSA, hoʻouna ʻo 5G a me 4G i ka ʻikepili i ka manawa like ma luna o kahi pilina ʻelua, maʻamau ʻo 5G ma ke ʻano TDD a me 4G ma ke ʻano FDD.Ma kēia ala, he aha ka mana e hoʻouna i ke kelepona paʻa?
Ma ke ʻano SA, hiki iā 5G ke hoʻohana i ka TDD a i ʻole FDD i ka hoʻouna lawe hoʻokahi.A e hōʻuluʻulu i ka mea lawe o kēia mau ʻano ʻelua.E like me ka hihia o ke ʻano NSA, pono ke kelepona kelepona e hoʻouna i ka ʻikepili i ka manawa hoʻokahi ma nā ʻāpana alapine ʻelua, a me TDD a me FDD ʻelua mau ʻano;ehia ka nui o ka mana e hooili ai?
Ma waho aʻe, ehia ka nui o ke kelepona paʻa e hoʻouna i ka mana inā e hui ʻia nā mea lawe TDD ʻelua o 5G?
Ua wehewehe ʻo 3GPP i nā pae mana he nui no ka pahu.
Ma Sub 6G spectrum, ka pae mana 3 he 23dBm;ʻO ka pae mana 2 he 26dBm, a no ka pae mana 1, ʻoi aku ka nui o ka mana theoretical, a ʻaʻohe wehewehe i kēia manawa.
Ma muli o ke alapine kiʻekiʻe a me nā hiʻohiʻona hoʻouna ʻokoʻa mai Sub 6G, ʻoi aku ka noʻonoʻo ʻana o nā hiʻohiʻona noi i ka hoʻoponopono ʻana a i ʻole ka hoʻohana kelepona ʻole.
Hōʻike ka protocol i ʻehā mau pae mana no ka hawewe millimeter, a ʻano ākea ka papa kuhikuhi radiation.
I kēia manawa, hoʻohana nui ʻia ka hoʻohana pāʻoihana 5G ma ka lawelawe kelepona kelepona eMBB ma Sub 6G band.ʻO kēia ka mea e nānā pono ai i kēia hiʻohiʻona, e ʻimi ana i nā pūʻulu alapine 5G (e like me FDD n1, N3, N8, TDD n41, n77, N78, etc.).Māhele ʻia i ʻeono ʻano e wehewehe ai:
- 5G FDD (SA mode): ʻo ka pae kiʻekiʻe loa o ka mana hoʻouna he pae 3, ʻo ia ka 23dBm;
- 5G TDD (SA mode): ʻo ka mana hoʻouna kiʻekiʻe loa he pae 2, ʻo ia ka 26dBm;
- 5G FDD + 5G TDD CA (SA mode): ʻo ka mana hoʻouna kiʻekiʻe loa he pae 3, ʻo ia ka 23dBm;
- 5G TDD + 5G TDD CA (SA mode): ʻo ka pae kiʻekiʻe loa o ka mana hoʻouna he pae 3, ʻo ia ka 23dBm;
- 4G FDD +5G TDD DC (NSA mode): ʻo ka mana hoʻouna kiʻekiʻe loa he pae 3, ʻo ia ka 23dBm;
- 4G TDD + 5G TDD DC (NSA mode);ʻO ka mana hoʻouna kiʻekiʻe loa i wehewehe ʻia e R15 he pae 3, ʻo ia ka 23dBm;a kākoʻo ka mana R16 i ka pae mana hoʻouna kiʻekiʻe 2, ʻo ia ka 26dBm
Mai nā ʻano ʻeono i luna aʻe nei, hiki iā mākou ke ʻike i kēia mau hiʻohiʻona:
I ka lōʻihi o ka hana ʻana o ke kelepona paʻa i ke ʻano FDD, ʻo 23dBm wale nō ka mana hoʻouna kiʻekiʻe, ʻoiai ma ke ʻano TDD, a i ʻole ka pūnaewele kūʻokoʻa ʻole, ʻo 4G a me 5G nā ʻano TDD ʻelua, hiki ke hoʻomaha ʻia ka mana hoʻouna kiʻekiʻe i 26dBm.
No laila, no ke aha e mālama nui ai ka protocol iā TDD?
E like me kā mākou e ʻike ai, ʻokoʻa nā manaʻo o ka ʻoihana kelepona e pili ana i ka radiation electromagnetic.Eia nō naʻe, no ka palekana, pono e kaupalena ʻia ka mana hoʻouna o nā kelepona paʻa.
I kēia manawa, ua hoʻokumu nā ʻāina a me nā hui i nā kūlana olakino e pili ana i ka radiation electromagnetic radiation, e kaupalena ana i ka radiation kelepona i kahi liʻiliʻi.I ka wā e hoʻokō ai ke kelepona paʻa i kēia mau kūlana, hiki ke manaʻo ʻia he palekana.
Kuhi ʻia kēia mau kūlana olakino i hoʻokahi hōʻailona: SAR, i hoʻohana pono ʻia no ke ana ʻana i nā hopena o ka radiation kahua kokoke mai nā kelepona paʻalima a me nā mea kelepona ʻē aʻe.
ʻO SAR kahi kikoʻī Absorption Ratio.Ua wehewehe ʻia ʻo ia ke ana ʻana i ka nui o ka ikehu ʻana i kēlā me kēia ʻāpana nui e ke kino kanaka ke ʻike ʻia i kahi pā uila uila (RF).Hiki iā ia ke kuhikuhi i ka absorption o nā ʻano ikehu ʻē aʻe e ka ʻiʻo, me ka ultrasound.Ua wehewehe ʻia ʻo ia ka mana i lawe ʻia no ka nui o ka ʻiʻo a loaʻa nā ʻāpana watts no ka kilo (W/kg).
Kuhi ʻia ke kūlana aupuni o Kina i nā kūlana ʻEulopa a ʻōlelo ʻia: “ʻaʻole ʻoi aku ka nui o ka waiwai SAR o kēlā me kēia 10g o nā mea ola no nā minuke ʻeono ma mua o 2.0W/Kg.
ʻO ia hoʻi, a loiloi kēia mau ʻano i ka nui o ka radiation electromagnetic i hana ʻia e nā kelepona paʻa i kekahi manawa.Hāʻawi ia i kahi kiʻekiʻe iki i ka mana pōkole, ʻoiai ʻaʻole i ʻoi aku ka waiwai ma mua o ka maʻamau.
Inā he 23dBm ka mana hoʻouna kiʻekiʻe ma ke ʻano TDD a me FDD, ke hoʻouna mau nei ke kelepona paʻa i ka mana FDD.ʻO ka hoʻohālikelike, ʻo ke kelepona paʻa i ke ʻano TDD he 30% wale nō ka mana hoʻouna, no laila ʻo ka nui o ka mana hoʻokuʻu TDD ma kahi o 5dB ka liʻiliʻi ma mua o FDD.
No laila, no ka uku ʻana i ka mana hoʻoili o ke ʻano TDD e 3dB, aia ma ke kumu o ka maʻamau SAR e hoʻoponopono i ka ʻokoʻa ma waena o TDD a me FDD, a hiki i ka 23dBm ma ka awelika.
