2 Preface Issue 3 of has bee released to reflect chages to Idustry Caada s policy o the usage of the bad GHz, as described i SP 14.5 GHz. This SRSP replaces, Provisioal, Issue 2. The followig are the mai chages: 1. The bad usage sectio has bee revised to reflect the Departmet s decisio to allocate certai parts of the bad for exclusive use by the Govermet of Caada of the aeroautical mobile service. 2. The permitted types of radio systems to be used i the bad have bee updated to allow low capacity (LC), medium capacity (MC) ad high capacity (HC) systems throughout the remaiig spectrum. 3. The chael pla sectio has bee revised to reflect the Departmet s decisio to allow the use of 5, 10, 20, 30, 40, ad 50 MHz chaels i all remaiig sub-bads allocated to fixed radio systems. 4.

4 Radio Systems Operatig i the Bad GHz 1. Itet 1.1 This Stadard Radio System Pla (SRSP) states the miimum techical requiremets for the efficiet use of the frequecy bad GHz by lie-of-sight radio systems i the fixed service, amely: low capacity (LC), medium capacity (MC) ad high capacity (HC) radio systems that use digital modulatio; ad temporary oe-way radio liks that carry video sigals for program feed to broadcastig or CATV studios, for vehicular traffic ad security surveillace, ad for other applicatios where a temporary radio lik is required. Video sigals iclude televisio ad radar video iformatio. Portable televisio cameras that trasmit to mobile radio or tape relay uits may operate i the bad. 1.2 This SRSP is iteded to be employed i the desig ad specificatio of radio systems ad equipmet, as well as i the techical evaluatio of applicatios for ew radio facilities or modificatio to radio systems submitted i accordace with the curret issue of Radio Stadards Procedure RSP-113, Applicatio Procedures for Plaed Radio Statios Above 960 MHz i the Fixed Service. 1.3 This SRSP specifies equipmet characteristics related to efficiet spectrum usage oly, ad is ot to be regarded as a comprehesive specificatio for equipmet desig ad/or selectio. 2. Geeral 2.1 This stadard replaces, Provisioal, Issue 2. Further revisio of this SRSP will be made as required. 2.2 Existig radio systems operatig i the paired bads / GHz ad / GHz that were licesed as stadard prior to the issuace of this SRSP may cotiue to operate as stadard. Extesio or expasio of these systems will be cosidered by Idustry Caada o a case-by-case basis. New systems deployed i the paired bads / GHz ad / GHz must coform to the requiremets of this stadard. 2.3 As described i SP 14.5 GHz, the use of the bads GHz ad GHz is desigated for govermet-exclusive aeroautical mobile applicatios i the mobile service. Accordigly, ew stadard or o-stadard fixed radio system licese applicatios i the bads GHz ad GHz will ot be cosidered. Existig poit-to-poit radio systems operatig i the bad GHz ad GHz are gradfathered util October 1, Begiig o October 1, 2013, fixed service systems may cotiue to operate, but shall ot claim protectio from Govermet of Caada systems operatig i the aeroautical mobile service. Begiig o October 1, 2017, fixed service systems may cotiue to operate i these bads, but shall ot cause harmful iterferece to Govermet of Caada systems operatig i the aeroautical mobile service. 1

5 Radio Systems Operatig i the Bad GHz 2.4 Radio systems coformig to these techical requiremets will be give priority i licesig over o-stadard radio systems operatig i this bad. 2.5 The arragemets for o-stadard systems are outlied i SP GEN, Geeral Iformatio Related to Spectrum Utilizatio ad Radio Systems Policies. 2.6 The Geographical Differeces Policy (GDP) guidelie applies i this frequecy bad. More iformatio o the GDP ca be foud i SP 1-20 GHz Eve though a radio system complies with the requiremets of this SRSP, modificatios may be required to the system wheever harmful iterferece 2 is caused. 2.8 Whe potetial coflict betwee radio systems caot be resolved by the parties cocered, Idustry Caada should be advised, ad after cosultatio with the parties cocered, will determie the ecessary modificatios ad schedule of modificatios to resolve the coflict. 2.9 Idustry Caada may require licesees ad/or applicats to use receiver selectivity characteristics that provide rejectio of harmful iterferece The use of a two-frequecy pla is required. Where reasoable ecoomic or techical justificatio is provided (e.g. where sitig prevets adequate atea discrimiatio), extra frequecies may be used to resolve the problem, subject to the provisios of the GDP as refereced i Sectio It should be oted that the fixed terrestrial service shares this bad with other services i accordace with the Caadia Table of Frequecy Allocatios 9 khz to 275 GHz. 3.

11 Radio Systems Operatig i the Bad GHz 6. Trasmitter Characteristics 6.1 Trasmitter Characteristics for LC, MC ad HC Radio Systems The trasmitter power delivered to the atea iput per RF chael shall ot exceed the followig limit for each badwidth: Badwidth Power Limit (MHz) (Watts) (dbw) , The cetre frequecy of the emissio shall be maitaied with ± 0.003% of the assiged frequecy Emissio Limits (a) The trasmitter emissios i ay 1 MHz bad, the cetre frequecy of which is removed from the assiged frequecy by more tha 50% up to ad icludig 250% of the authorized badwidth, shall be as specified by the followig equatio. A = (P - 50) + 10 log 10 B where A = atteuatio (i db) below the mea output power level P = percet removed from the cetre frequecy of the assiged RF chael B = authorized badwidth (i MHz) Note: 1. I o case shall the atteuatio be less tha 11 db. 2. Atteuatio greater tha 56 db or to a absolute power of less tha -13 dbm/mhz is ot ecessary. (b) The trasmitter emissios i ay 4 khz bad, the cetre frequecy of which is removed from the assiged frequecy by more tha 250% of the authorized badwidth shall be atteuated by log 10 (mea output power i watts) or 80 db, whichever is the lesser atteuatio. 8

12 Radio Systems Operatig i the Bad GHz 6.2 Trasmitter Characteristics for Temporary Radio Liks The trasmitter power delivered to the atea iput per RF chael shall ot exceed 2.0 watts (3.0 dbw) The cetre frequecy of the emissio shall be maitaied withi ± 0.005% of the assiged frequecy Frequecy or amplitude modulated emissios may be used. The maximum RF chael badwidths are show i Table 1. Note that the badwidth for chaels E 1 ad E 8 is restricted to 12.5 MHz. Whe used, a badwidth of 16 MHz for chaels E 2 to E 7 permits up to three sub-carriers to be trasmitted alog with a video sigal i temporary liks used for televisio pickup. However, radio equipmet should have adequate filterig such that RF emissio ad receptio badwidth characteristics allow operatio of separate systems o adjacet chaels usig orthogoal polarizatio, whe the udesired ad the desired sigal are of the same magitude at the iput of the receive atea Upo special applicatio to the resposible regioal office of Idustry Caada, a licesee may be permitted to operate a temporary radio lik carryig radar video where the chael badwidth is more tha 16 MHz but does ot exceed 25 MHz. I such a case, a adjacet pair of chaels betwee E 2 ad E 7 iclusive may be used subject to frequecy coordiatio through the regioal office. 7. Iteratioal Coordiatio Caada does ot curretly have a formal arragemet with the U.S. govermet for the sharig of the GHz frequecy bad alog the border regios. Licesees will be subject to ay future agreemets betwee Caada ad the Uited States regardig use of these systems i the border regios, which may iclude obtaiig departmetal approval before allowig certai statios to operate. 8. Atea Characteristics 8.1 Atea Characteristics for LC, MC ad HC Radio Systems The co-polarized radiatio patter evelope i the horizotal plae of the atea must remai withi evelope A show i Figure 2 ad Table 2 for both vertical ad horizotal polarizatio I moderately or highly cogested areas (as defied i the GDP refereced i Sectio 2.6), the co-polarized radiatio patter evelope i the horizotal plae of the atea must remai withi evelope C show i Figure 2 ad Table 2 for both vertical ad horizotal polarizatio. 9

Such ateas should also have the capability to chage polarizatio. 9. Maximum Equivalet Isotropically Radiated Power (e.i.r.p.) 9.1 The e.i.r.p. from the atea must ot i ay case exceed +55 dbw per RF chael. 10. Avoidace of the Geostatioary Satellite Orbit 10.1 As far as practicable, sites for trasmittig terrestrial statios operatig i the fixed service ad employig a maximum e.i.r.p. value exceedig +45 dbw i the frequecy bad GHz, should be selected so that the directio of maximum radiatio of the atea will be poited at least 1.5 o away from the geostatioary satellite orbit, takig ito accout the effect of atmospheric refractio. 10
