Wireless Bridge Point to Point, 900MHz Outdoor WiFi Bridge with 2000 feet Long Range Transmission Distance

First things first; these are NOT super high speed/throughput. These are made to be used in situations where conventional wifi does not work at all, due to distance or line of sight barriers. As long as you understand this, these are very useful little network appliances. Overall I am quite impressed with them, for what they are.I am using this bridge to extend my home network out to my garage, where I am getting 7-8MBPS up/down, and this is pretty slow by modern standards but MUCH better than the 0MBPS I was getting with conventional 2.4/5GHz wifi, which simply could not reach my garage from inside the house, while these can easily bridge the gap even from the opposite side of the property.They are extremely plug-and-play, requiring no real configuration. Just plug the provided antennas, power, and ethernet cables in, and as long as the received signal strength is good enough it just seems to work. A clear line of sight between the two device's antennas gives them the best shot at obtaining maximum throughput, but they will work at reduced speed without direct line of sight, certainly better than conventional wifi in that respect.Technical details for nerds: these are based on these Gaotek wireless modules, specifically the P9-NR variant: https://gaotek.com/wp-content/uploads/2024/02/GAOTek-WM-135-Technical-Documentation-User-Manual-or-Instruction-Manual-1.pdfI am very pleased that these have normal polarity SMA connectors rather than RP-SMA, this means that if you know what you're doing, you can connect higher gain antennas than the provided whip antennas (check your area's laws before doing this! Unlicensed ISM band devices like these are limited in terms of how much power + antenna gain they can have).

I used these to prove out an idea for installing a video camera at a back gate on my ranch. I am a rancher and not an ff engineer so these units fit the bill for testing. As advertised they are good quality products that were easy to set up and operate. Range and signal quality were not what I needed but I was able to test the camera. I don't have the technical expertise to fine tune the units so I am probably not getting their maximum range and speed performance. I ended up buying Ubiquiti products to build the signal bridge. They were slightly more expensive but were much more powerful and just as easy to set up.

I couldn't get these units to work at all. The worst part is there is just no help to get them working. The instructions are very vague. I know it said plug and play but they didn't work for me.

First of all, these are 900MHz units. That means "slow compared to wifi". In ideal conditions, the real speed is around 10mbps, a fraction of wifi. What is good, is that even in less than ideal conditions (no line of sight, distance) they can get up to 5mbps when a 2.4GHz repeater will have no signal. So, slow is better than nothing.These devices are based on the Taixin TXW8301 modules, which are decently well documented and tools are available. The problem, like all Taixin modules, is that security is not strong by default. Without getting too technical, the encryption key is based on the module serial number, and easy to snoop with the proper tools (see the DEFCON32 talk on this for details).The seller replies to support requests, but doesn't provide actually useful information. The seller doesn't provide the necessary tools to secure the devices, but it's easy to download the tools from the Taixin website and change the encryption key to a secure one. Also, the devices arrive with a very old firmware (1.3.8.3) with a bug that drops packets after a few days, but there is new firmware on the Taixin website (1.6.3.3) which works very reliably.If you are decently technical, these devices with the right encryption key and firmware are 5 stars. Considering the lack of support/tools from the seller, for most people are 3 stars at best. If you own these, look online for the tools and instruction on updating them

Works well with low bit error rate, but only expect around 10 to 12 MB baud rate.

We have a detached garage. There are 4-5 walls between our apartment and our garage so obviously our wifi doesn’t reach. We tried several different wifi extenders and none of them worked. This one does work, though we don’t get much bandwidth. It’s enough bandwidth for a smart garage door opener but not enough to stream video from a security camera. Works better than anything else we tried, so can’t complain.

I got that to connect a greenhouse 550 feet away with a clear line of sight from the window where the Tx module is located. Surprisingly to me I only have a 1 bar connection and a barely usable connection that is extremely limited and insufficient for my needs. 3MBPS up and 1 down would have worked for me but I am nowhere near this.Using an extension cord I did some testing outside in the wide open space with no obstructions. With both units together I got the full 3 bars. However, at a distance of only 55’ it dropped to 2 bars and dropped to one bar at a distance of only 73’.Since it indicate it will work at distances up to 3000’ I expected a much better much better connection strength at only 550’.
