CBRS Training notes questions with answers
// // // // //




aggregate //interference //constraint //- //correct //answer(s) //✔✔ //means //that //the //total //amount
//of //noise //caused //to //each //higher //priority //user //is //kept //to //acceptable //levels.




SAS //- //correct //answer(s) //✔✔ //Spectrum //Access //System. //The //scalable //cloud //service //that
//manages //CBRS //transmissions. //The //SAS //manages //information //about //all //users //of //the


//CBRS //band,



in //order //to //ensure //that //higher //priority //users //are

protected //from //harmful //interference.



What //frequency //band //does //CBRS //operate //- //correct //answer(s) //✔✔ //3550 //MHz //to //3700
//MHz




What //are //the //three //tiers //for //CBRS //users? //- //correct //answer(s) //✔✔ //• //Tier //1 //- //Tier //one //is
//the //incumbents. //They //were //here //first //using //the //spectrum //before //the //CBRS //band //was


//created,



so //they //get //top //priority //wherever //overlap //happens.



• //Tier //2 //- //goes //to //CBRS //users //who //paid //to //be //protected //from //interference //from //users
//in //the //third //tier. //They //do //this //by //buying //a //priority //access //license, //or //PAL, //at //an


//auction. //Having //a //PAL //still //doesn't //guarantee //access //at //all //times, //because //only


//incumbents //get //that. //But //the //PAL //protects //a //tier //two //user //from //having //their //service


//interrupted //by //the //users //of //the //third //tier.




• //Tier //3 //- //general //authorized //access //users, //or //GAA //users.

GAA //users //can //use //the //CBRS //spectrum //if //it's //not //being //used //locally //by //the //other //two
//tiers //at //that //time. //If //a //higher //priority //user //is //using //a //portion //of //the //spectrum //at //that

, //time, //GAA //users //may //need //to //move //to //other //parts //of //the //CBRS //band. //GAA //users
//don't //get //any //interference //protection //from //the //other //tiers, //but //they //have //a //much


//much //lower //cost //since //they //don't //need //to //buy //a //license.




PAL //- //correct //answer(s) //✔✔ //priority //access //license. //protects //a //tier //two //user //from
//having //their //service //interrupted //by //the //users //of //the //third //tier.




What //does //a //PAL //cover //- //correct //answer(s) //✔✔ //PAL //covers //one //county(only //covers
//areas //you're //actually //using //the //pal //not //the //hole //county) //and



offers //protection //for //a //single //10 //megahertz //channel.



PPA //- //correct //answer(s) //✔✔ //PAL //protection //area. //is //a //contiguous //area //created //by
//calculating //the //combined //service //areas //of



individual //transmitters //owned //by //the //PAL //user.



CBRD //- //correct //answer(s) //✔✔ //CBRS //devices //called //CBSDs

talk //to //the //SAS //in //order //to

obtain //permission //to //transmit.

They //only //get //that //permission //if //they //won't //be //causing

any //harmful //interference //to //higher //priority //users. //typically //base //stations //or //access
//points,



and //they //need //to //communicate //directly //with

the //SAS //before //they //use //the //CBRS //band.



EUD //- //correct //answer(s) //✔✔ //End //user //device. //Are //not //CBSDs //because //they //adhere //to
//stricter //power //limitations //and //do //not //talk //to //the //SAS
