- wyager 5y ago> High frequency = high power This isn’t true in any sense applicable to this discussion. For example a near-optical laser transmitter can be as or more efficient in joules per bit than an RF transmitter, depending on the situation.
- SavantIdiot 5y ago> A near-optical laser transmitter Do you have to aim that laser transmitter?
- wyager 5y agoDepends on the application, but if you do, it won’t pose a problem: * you have more options than with RF (optics or phased array) * you’ll get better angular precision at a given transmitter size
