| tie odrusovace nemaju velku ucinnost voci ruseniu z oklia. pomahaju hlavne voci ruseniu sa radii na jednom sajte, ktore mas namontovane pri sebe.. Vyskusal som vsetky mozne druhy tienienia, ale nic nezabralo tak, ako pouzitie hornov. Tam bolo vidiet najvacsie zlapsenie. |

| Takze namontoval som to az dnes. Skoro k ziadnemu zlepseniu neprislo, noise floor kleslo o 1dBm, celkovo mi prislo ze signal sa na klientoch sa zhorsil 2 -3 dBm, ten co bol na krajnom laloku toho odrezalo. asi poucny pokus za 25e |

| Nuz zvykol som si delit oblast max na 90 stupnove sektory, takze PriamAP-90 je idealne volba. Vyhodou tychto hornov je aj to, ze maju homogennejsie vyzarovacie charakteristiky ako klasicke sektory, ktore maju vacsinou vo vertikalnej rovine podstatne mensi lalok. |

Ozivujem trosku temu. Dlho bol klud a zrazu prenosova kapacita linky klesla na prevratnych 20-50Mbit z povodnych 100-200Mbit. Chcem sa opytat pomoze mi na tomto mieste vymenit LBE-5AC-16-120 za Rocket 5AC PRISM gen2 s 16-120 sektorovkou? viem spominali ste tu ze je lepsie sektory rozdelit najviac do 90 stupnov alebo aj menej ale musel by som kvoli tomu vytvarat druhy bod co sa mi fakt nechce.
Stoji ten prism za tych 200e alebo mi to vobec nepomoze? |

| Ja som tie sektorky takmer vsade vymenil za horny a odvtedy to ide podstatne lepsie. Dokonca aj na backup jedneho spoja som pouzil namiesto PBE620 velky horn a ide to podstatne lepsie. |

K tejto teme vam mozem napisat, ze v nasom pripade sa stalo ze:
na jednom sajte cca 150m vzdialeneho od Orange po spusteni "noveho zariadenia"
- sektor s LAP-120 absolutne ziadna zmena
- sektor s AC Prism isiel dole zo 100/80 na 60/60 (je takmer presne oproti)
na sajde zdielanom s Orange
- sektor s LAP-120 isiel dole z cca 70/70 na 60/30
- sektory s LAP-90-GPS absolutne ziadna zmena.
A tomuto uz nerozumiem vobec.
Este doplnim ze problem je pravidelne v case cca od 8.00 do 23:59 |

uz kotol tu predtym spominal tuto lte featurku :
https://www.everythingrf.com/community/ ... ted-access
License Assisted Access (LAA) is a feature of LTE that leverages the unlicensed 5 GHz band in combination with licensed spectrum to deliver a performance boost for mobile device users. It uses carrier aggregation in the downlink to combine LTE in unlicensed 5 GHz band with LTE in the licensed band to provide better data rates and a better user experience.
Since this technology operates in the 5 GHz band where Wi-Fi operates, it must be able to co-exist with Wi-Fi by avoiding channels that are being used by Wi-Fi users. LAA uses a concept called Listen-before-talk (LBT) which dynamically selects channels in the 5 GHz band which are not being used by Wi-Fi users. If there is no clear channel available, LAA will share a channel fairly with others.
Advantages of LTE-LAA Technology
Consumers can leverage the combination of licensed and unlicensed bands to achieve higher peak rates indoor and outdoor.
By distributing traffic between the licensed and unlicensed bands, LAA frees up capacity on the licensed spectrum, benefiting users on those bands.
LAA frees up capacity for Wi-Fi users, by employing fair sharing techniques and using the 5GHz band more efficiently.
LAA Enables mobile operators to offer Gigabit Class LTE by using small chunks of licensed spectrum.
Licensed Assisted Access (LAA) was introduced in the 3GPP release 13 as part of LTE Advanced Pro. LAA gives a performance boost to smartphone users, while optimizing available wireless network resources for all users. Combining licensed and unlicensed technologies is a key milestone towards the road to 5G. |
