Lease agreement, description	In May 2021, DragonWave entered into an amendment to its existing facility lease to extend the expiration date through June 20, 2022 and to increase the annual base to $12 thousand per month. The lease did not include an implicit rate of return; therefore, the Company used an incremental borrowing rate based on other leases with similar terms. The modification resulted in additional right-of-use asset and lease liability of $0.12 million As part of the RVision business acquisition on April 1, 2021, the Company assumed a lease of office space with a remaining term of approximately 33 months that will expire on March 31, 2024. Monthly payments are $7 thousand during the remaining life of the lease.	Monthly payments range from approximately $1 thousand to approximately $2 thousand. Each lease had an implicit rate of 6.0% and no renewal options.
