What is a unlicensed microwave link?
Unlicensed and light licence wireless links is the most cost effective of all links and can be deployed in a matter of days. Currently in most countries there are a few unlicensed ISM-band frequencies that are used for point to point links and a few light licensed frequencies that provide interference free operation.
What is a light licensed microwave link?
Regional regulators (typically, in each country) are responsible for Spectrum Management of the Radio Spectrum. This naturally varies in each country due to different history of usage and allocation.
A Light License is where the licensee pays a small licence fee to register his/her radio link with regional regulators such as OFCOM (UK).
The regulator (such as OFCOM in the UK) use the licence to inform other potential users of the spectrum that there is already a radio link or links in the area when they register their own link prior to deployment. This information is also used to resolve disputes should interference arise.
Depending on which country you are in, these can include:
- Licence free spectrum are the 5Ghz, 24Ghz, and 60GHz frequencies
- Light licence spectrum operate in the 64-66GHz and 70/80GHz
Why consider unlicensed or light license links?
- Low density areas not suffering from RF interference
- Budget constraints
- Non-critical data transmission
When are licensed links mostly used?
- Organisations looking to create a LAN across multiple buildings on the same site
- Organisations looking to reduce the cost of existing leased lines
- In low density areas where RF interference is low or free
When to consider opting for a licenced over unlicensed?
- High density areas suffering from RF interference
- Mission-critical data transmission
