In a recent letter, Ira Wilner wrote to say that people should be using W-Fi streaming rather than Part 15 transmissions for outdoor events.
Were latency not a considerable issue, he would be right. However, using Wi-FI streaming systems can give as much as two seconds latency, which is very disconcerting when you are watching someone speak.
There are some streaming systems out there that claim to reduce this latency but they are not inexpensive and they can still do nothing about the receiving half of the system.
There is, sadly, still a need for leaky coax AM systems taped to parking lot surfaces today.
