Startup touts microwave LOS 4x4 MIMO for last-mile LTE backhaul

South Africa-based MIMOtech took the wraps of its Starburst Janus packet radio, which employs microwave line-of-sight (LoS) 4x4 MIMO multi-antenna technology and parallel radio processing.

The two-year old startup claims Starburst Janus yields spectral efficiency of 25 bits/sec/Hz and enables data rates of several gigabits per second on a single frequency channel. The technology doubles the performance of traditional non-line of sight MIMO measured in either capacity or distance and lowers the cost per bit transported, said MIMOtech. The vendor is targeting Starburst Janus for last-mile LTE backhaul.

The company also claims its device requires smaller antenna spacing than other LoS MIMO products on the market. Starburst Janus employs a patented configuration of LoS MIMO that uses two cross-polarized antennas spaced 1.5 meter apart, resulting in a mechanical configuration occupying a space that is comparable to that of a LTE sector antenna.

MIMOtech was launched in 2011 and is active in ultra-high-capacity backhaul, high-capacity backhaul and high-capacity access. Private individuals make up 72.4 percent of the company's shareholders. The Industrial Development Corporation of South Africa and Optimus Investments hold shareholding interests at 25 percent and 2.6 percent, respectively.

The backhaul market is attracting numerous startups. A recent study from Strategy Analytics revealed that backhaul demands are going to increase in the years ahead, and carriers worldwide are collectively underfunding investment in backhaul. The Tellabs-commissioned report said carriers' operating margins could improve by up to 5 percent if backhaul investment increases to meet traffic growth.
