![]() ![]() Then I check how far apart the buildings are. When I need to connect two buildings at Gigabit speeds, Ethernet Lasers are the first thing that I think of. Gigabit performance has its strength and some weaknesses You will also require specialist radio installers and regular maintenance programs. This license will need to be reviewed every year and a fee will be charged. Requirements vary from country to country, but you typically need to be certified or licensed by the government to use that spectrum in that location. Using proprietary 802.11 equipment you might get as much as 80Mbps throughput in actual use due to loss and signalling overheads.Īnother solution is to use Radio technology operating in the 3 to 5 Gigahertz frequency ranges. Maybe you can get up to 30 MBps in most practical situations. Since the 802.11 2.4 Ghz spectrum is so crowded these days, using 802.11b/n doesn’t get you much performance. Plus it will take two months to be installed.Ī common solution is to use 802.11 style Wireless Ethernet because many people are familiar with it but the performance is not so great. A WAN connection costs a lot to install and even more to rent every month.makes installing your own fibre quite difficult. ![]() For example, your company takes another office on the other side of the road which: In many designs, lasers are the simplest way to connect two buildings when you can’t use fibre. These lasers are used to transport Ethernet ((once upon a time you could get ATM versions but who cares about that now?))frames across a long distance by carrying the Ethernet signal over a laser bearer. A long distance is somewhere between metres.Ĭonceptually similar to Infra Red ports (that we used to have) on our computers to connect our Palm Pilots and printer except more focussed and more powerful. ![]() Free Space Optics is the term used to describe using infrared lasers to transfer Ethernet across a long distance. ![]()
