There are actually two sites up in East Brunswick. Both are off Route 18 and you get a good LTE signal if you're within the vicinity of 18. Check Sensorly. They're also testing another East Brunswick site that's giving off a signal near the NJ Turnpike.
I live in North Brunswick, and we have smaller pockets of LTE than you do. You gotta try and make the best of the situation, because it's only gonna get better from here.
