1. I see this as the best solution. It can and will be expensive for a good mesh system. Mesh offers seamless roaming and good scalability by adding extra units. Rated speeds are up to or over 1Gbps but real world speeds will be lower. Well placed adapters will provide speeds well over the current 60Mbps. Plan on getting a tri-band system since it will offer the best throughput. Also plan on spending over CDN$500.I only have 3 options: 1. wifi mesh 2. powerline 3. moca
There could be some excess loss over 1000MHz with cable splitters. Satellite splitters should also work better than cable splitters. They are rated 5-2400MHz and might be a bit easier to find or be cheaper than Mocha splitters. I've seen them for $5-10 on some sites. Another option that should work even better are diplexers. They split the signals above and below 1000MHz into two bands to help prevent interference. They also have lower signal loss than splitters. I've used these to run cable or OTA (5-1000MHz) and satellite (1000-2400MHz) over the same coax.I could get moca 2 rated splitters rated at 5-1650Mhz but not sure if it would make much difference.
