Decisions on a Band Plan for Broadband Radio Service (BRS) and Consultation on a Policy and Technical Framework to License Spectrum in the Band 2500-2690 MHz

Part A – Decisions on Band Plan and Mapping of Incumbents to the New Band Plan (continued)

1. Band Plan (continued)

1.3 Realigned Spectrum Blocks

In adopting the ITU band plan in Canada, the amount of spectrum to be returned to the Department will need to be adjusted, as the ITU band plan is based on 5 MHz blocks. The 2006 Policy Decision stated that returned spectrum would equal approximately one third of the formerly authorized MCS/MDS spectrum. In DGSO-001-10, the Department proposed that the exact spectrum blocks to be returned be amended from 2535–2568 MHz to 2540–2570 MHz and from 2657–2690 MHz to 2660–2690 MHz (i.e. a slight decrease from 2 x 33 MHz blocks to 2 × 30 MHz blocks). In addition, consistent with the ITU band plan, the Department proposed that two blocks of 5 MHz (2570–2575 MHz and 2615–2620 MHz) be used as guardbands between the paired and unpaired spectrum. In DGSO-001-10, the Department also proposed spectrum exchange plans that could facilitate the use of paired spectrum by incumbent licensees.

Consistent with the 2006 Policy Decision, the proposed band plan and incumbent mapping proposals in DGSO-001-10 represent approximately one third of the originally authorized spectrum. This is illustrated in Figure 4 and Table 1 below.
