LigoWave is announcing a release of a new v6.70 open beta firmware for LigoPTP MiMo equipment. LigoWave has developed a new protocol named W-Jet MiMo 2™, which allows to increase the distance and performance of a link. This ground-breaking technology delivers 180 Mbps half-duplex and increases the distance of the link to more than 100 kilometers. It also makes the link more robust in a noisy environments where other equipment would not even associate or provide a really low throughput.
10 km test link in Vilnius, Lithuania with W-Jet MiMo 2 firmware
LigoWave has made 10 kilometre test link in a very noisy area with many equipment working on the same 5 GHz frequency. With the new W-Jet MiMo 2 protocol it was possible to reach 140 Mbps of throughput (see Picture 3). The settings of the link were as follows:
Channel: 5210 MHz;
Channel width: 40 MHz;
Data rate: 270 Mbps;
Transmit power: 25 dBm;
Signal levels on a master and remote side: -47;-49/ -50;-52.

Successful tests in Mexico
Some customers also had a chance to test the latest firmware and see what results they can achieve on long-distance links. LigoWave customer in Mexico was happy to try out the new beta software and achieved such results on their 3 links:
Tule(hill) – Culagua(hill) – 70 Km link – Throughput 74 Mbps
Culagua(hill) – La viga(hill) – 47 Km link – Throughput 122 Mbps
La viga(hill) – Neveria(hill) – 77 Km link – Throughput 70 Mbps
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.
LigoPTP MiMo
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 61000-4-5 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.
