Even with a business-class connection from the local cable company it didn't take long to clog the bandwidth up and then all I got were complaints. How many of you are regularly streaming movies and such with good results? The highest bandwidth plan I see from Comcast currently is 150Mbps download. That bandwidth will not be realized on a boat in a marina setting, so let's say you've got great line-of-sight and are getting 100Mbps. An HD video stream needs around 5Mbps. So once boat number 21 starts streaming nobody has 5Mbps any longer. Are the "streamers" here having any buffering issues at all or not?
Note: I'm not against streaming. I do it at home sometimes. I'm probably going to watch the Belmont in a few minutes by using my Slingbox connecting to my house (we're at anchor) via Verizon LTE as I'm too lazy to try and tune in my locals on satellite (I have to change the angle of the dish from the satellite that has most of my programming).

Kurt since all the Cable access points are at a minimum dual band 2.4GHz and 5.8GHz and all are at least 2 radios supporting MIMO or dual streams the air link speeds close to the AP`s are quite good. The vast majority of the users are close in and make use of the 5.8 GHz band leaving plenty of spectrum (2.4GHz) for distant/ remote (boat) use.
The Cable Alliance hotspots have a typical backhaul of >100mbps. I support the use of N radios (MIMO) for remote use. Using a B or G (SISO) remote radio limits your speed and the AP must slow down when a G client negotiates access with the AP. Typical close in airlink speeds are 300mbps per each N radio.
Combining the use of dual polarity with MIMO allows the remote client the ability to double the airlink speeds as well as minimize fading if both verticle and horizontal antennas are used.
