Wifi maybe? Narrow band radios like this aren't meant to transmit continously. They are all packet based with error correction for each packet

What type of radio? Does Nordic Semi have other such ICs?

I saw 130micros is the time constant switching from standby to TX. Can't I have 2 L01s 1 in TX transmitting continuously and RX receiving continuously?

For our application, we need continuous transmission.

Because of power consumption. The packets are very short, ~300 µs so you need to send then fast and do little for a while to save power. Speed isn't impontant here. If you want speed, you need another type of radio.

You don't want to transmit continously. You need time to re-transmit packets, change channel etc.

Does nordic have any other IC or module which can transmit continuously? 130 micros is so huge! What is the point of 2.4GHz speed if 130 micros is the overhead!

You will probably get better help in an Arduino forum here. But generally for the nRF24L01+, it takes 130 µs to send a packet, plus the length of the packet itself, from the time you set CE. So you're probbaly trying to send to fast.
