5G Bandwidth Part (BWP) – One of the Smartest Features in 5G NR!
Ever wondered how 5G achieves ultra-efficiency without draining your smartphone’s battery or overloading the network?
The secret lies in BWP – Bandwidth Part.
What is BWP?
It’s a flexible way to configure subsets of carrier bandwidth, allowing UEs (devices) to operate efficiently without using full bandwidth all the time.
Why is it Needed?
5G supports massive bandwidths (
up to 400 MHz)
Smartphones can’t constantly monitor all of it — it would kill the battery!
So, BWP intelligently balances performance with power efficiency
Types of BWP:
Initial BWP – RRC_IDLE / RRC_INACTIVE
Active BWP – RRC_CONNECTED
Default BWP – Used when no other is active
Use Cases:
mMTC: Narrow BWP for low-power IoT
eMBB: Wide BWP for blazing speed
URLLC: Custom BWP for ultra-low latency
BWP Switching & Config:
Up to 4 DL & 4 UL BWPs possible
Only 1 active at a time 
Switch triggered by traffic, QoS, or service type
This flexibility is what makes 5G smarter than ever.
Master BWP = Master 5G Optimization!
