Abstract

"LAçO LOCAL SEM FIO, PROCESSO DE TRANSMISSãO SEM FIO DE MENSAGENS DE TELECOMUNICAçõES DE RADIOFREQuêNCIA, PARTE FIXA DE RáDIO, E, UNIDADE DE ACESSO FIXA SEM FIO" Laços locais sem fio incluem antenas principalmente não verticalmente polarizadas. De preferência, o laço local sem fio inclui antenas polarizadas horizontalmente. Através do uso de antenas principalmente não verticalmente polarizadas no WLL, a interferência entre os sistemas de comunicação celulares, por satélites e/ou outros radiotelefónicos, que empregam, predominantemente, antenas polarizadas verticalmente, pode ser reduzida e, de preferência, minimizada. Sistemas radiotelefónicos celulares e por satélites convencionais usam transmissões polarizadas verticalmente devido à natureza vertical da orientação das antenas móveis nos veículos e/ou radiotelefones móveis. Contudo, em um WLL, com suas telecomunicações sem fio fixas, não há necessidade de usar antenas orientadas verticalmente. Conseq³entemente, para reduzir a interferência, e a antena esqueçam principalmente não verticalmente polarizadas são usadas."LOCAL WIRELESS TIE, WIRELESS TRANSMISSION PROCESS OF RADIOFREQUENCY TELECOMMUNICATIONS MESSAGES, FIXED RADIO PART, AND, FIXED WIRELESS ACCESS UNIT" Local wireless ties include mainly non-vertically polarized antennas. Preferably, the local wireless loop includes horizontally polarized antennas. Through the use of mainly non-vertically polarized antennas in the WLL, interference between cellular communication systems, via satellites and / or other radiotelephones, which predominantly employ vertically polarized antennas, can be reduced and, preferably, minimized. Conventional cellular and satellite radio systems use vertically polarized transmissions due to the vertical nature of the orientation of mobile antennas in vehicles and / or mobile radio telephones. However, in a WLL, with its fixed wireless telecommunications, there is no need to use vertically oriented antennas. Therefore, to reduce interference, and the antenna forget mainly not vertically polarized are used.
