LigoWave MiMo PTP units are being deployed by ISPs worldwide with astounding results. Here are some pictures from a successful backhaul link deployment in the Netherlands by WiMood.
The new LigoPTP MiMo products are far superior to the previous generation LigoPTP products in terms of spectral efficiency. Below you can see a data bits per hertz comparison chart for standard Wi-Fi, LigoPTP and LigoPTP MiMo equipment. The spectral efficiency of the LigoPTP MiMo equipment is over twice that of the previous product line.
Additionally, the theoretical data rate has increased from 108 Mbps to 300 Mbps, while the real throughput is over 180 Mbps compared to 70 Mbps on the standard PTP product. The advanced proprietary protocol called W-Jet™ and MiMo (multiple input multiple output) technology allows for higher throughput than the previous generation product and also increases reliability at the same speed level. For example, using the LigoPTP 5-23 product users were able to get 70 Mbps of real TCP throughput on a 1 kilometer (0.6 mile) link using the highest data rate and a 40 Mhz channel. However, with the LigoPTP MiMo product, to get such throughput users need only 20 Mhz channel and lower modulation. This means more efficient spectrum usage and less dependency on interference and bad weather conditions.
In addition to the previously mentioned advantages, all LigoPTP products will now have a more advanced electrostatic discharge (ESD) protection, compliant with:
- IEC 61000-4-2 level 4: 15 kV (air discharge); 8 kV (contact discharge);
- IEC 61000-4-4 level 4: ± 2 kV, 40 A (5/50 ns);
- IEC 61000-4-5 level 2: ± 1 kV, 42 O up to Tj = 150 °C;
- MIL STD 883G, Method 3015-7: 25 kV (human body model).
The new LigoPTP and LigoPTP MiMo housing is also IP-67 compliant and has an OLED screen which provides on-hand link tuning capability with an integrated antenna alignment tool and also a throughput test tool to check proper link functionality. See the video below to experience the OLED screen functionality.
