E-Band and V-Band - Survey on status of worldwide regulation

CEPT/ECC
At the same time the ECC has also produced ECC/REC(05)07[3], which, in its first release, did not foresee
any specific channel arrangement apart from a generic 250 MHz slot subdivision (max 19 slots per each
band, with 125 MHz guard band on each side) and the possibility of aggregating any of them up to any
size and, when FDD is concerned, duplex separation of 10 GHz (cross band duplex) or lower than 5 GHz
(in band duplex).

Later on in 2009 the ECC recognized the high importance that this band was assuming for the expected
high density deployment in 3G/4G mobile backhauling. Therefore, a revision of ECC/REC(05)07 was
made introducing specific channel arrangements for channel sizes ranging from 250 to 4750 MHz. The
arrangements remain flexible permitting TDD and FDD applications with 10 GHz as well as 2.5 GHz
duplex separation. These arrangements will ease the more efficient link-by-link coordination, which was
looked at by most CEPT administrations.
A summary of the main ETSI technical specifications for operation in E-Band is depicted in the following
