Demystifying 5G E – Your Guide to Understanding AT&T‘s Controversial "5G" Network

Hey there! I couldn‘t help but notice you recently upgraded to a new phone and are now seeing "5G E" in the status bar rather than 4G LTE. You‘re probably wondering what‘s up with that. As a fellow tech enthusiast, let me try to help demystify what 5G E is all about and whether it‘s the real 5G experience or just marketing hype.

What Exactly is 5G E?

In short, 5G E is AT&T‘s branding for their "5G Evolution" network technology, which is essentially an advanced form of 4G LTE rather than true 5G. It uses technologies like:

• 3x Carrier Aggregation: Combining 3 bands of wireless spectrum to increase data capacity.

• 4×4 MIMO: Using multiple transmit and receive antennas to enhance connections.

• 256 QAM: Encoding more data bits in the same radio waves.

By upgrading their 4G network with these advancements, AT&T can deliver faster LTE speeds and capacity. However, 5G E has some notable limitations compared to real 5G networks being built out:

Speeds: 5G E peaks at around 500-600 Mbps while 5G can hit over 1 Gbps. The average speed difference is even more substantial with 5G delivering 50-100 Mbps faster than 5G E.

Frequency: 5G E uses the same sub-6 GHz spectrum as 4G LTE, unlike true 5G‘s high-frequency mmWave bands.

Latency: The lag before data transfers is 30-50 ms on 5G E compared to 1-10 ms for 5G.

Technology: 5G uses an entirely new OFDM-based radio interface alongside LTE while 5G E remains based on LTE technology.

So in summary, while 5G E improves on 4G LTE, it does not offer the game-changing speeds, ultra-low latency, and next-gen capabilities that the 5G standard promises. But let‘s delve deeper into the details!

A Technical Breakdown: 4G LTE vs. 5G E vs. 5G

To better understand where 5G E fits in, let‘s compare some key technical specifications between 4G LTE, 5G E, and 5G:

Here are some key takeaways from comparing the specs:

• Speeds: 5G E sits between 4G and 5G in both peak and average download speeds. Real-world tests confirm around 2x faster speeds than LTE.

• Latency: Lag time is reduced from 4G but still much higher than the near real-time responsiveness of 5G.

• Spectrum: Like 4G, 5G E remains in lower frequency bands versus 5G‘s use of high-band mmWave frequencies.

• Architecture: The core network architecture remains Evolved Packet Core for 4G/5G E rather than the next-gen design of 5G.

So in nearly every technical aspect, 5G E is an evolution of 4G LTE – not the revolutionary re-invention that 5G enables.

Why the "5G" Name is So Controversial

Given that background, you can probably see why there is controversy around AT&T‘s decision to brand its enhanced 4G network as "5G Evolution" with a "5G E" icon. To many consumers, calling something 5G implies it delivers the amazing speeds and capabilities we‘ve been promised with next-generation 5G networks.

However, as we‘ve explored, 5G E lacks most of the hallmarks of a true 5G network. Industry experts and even competitors like T-Mobile have called out AT&T for potentially misleading customers by appropriating the 5G name prior to deploying a real 5G network.

AT&T‘s motivation comes down to perception – they want customers to think they are keeping pace with Verizon and T-Mobile in rolling out 5G. However, those competitors are focused on millimeter wave-based 5G which will far surpass the speeds and capabilities of 5G E.

Separating Hype from Reality: The User Experience

At this point you might be wondering: as a customer, is 5G E noticeably better than 4G LTE?

The answer depends on your location, device, and what you use your phone for. In general, 5G E does deliver incrementally faster speeds to compatible devices in supported areas. Based on user-reported tests, the average real-world speeds achieved on 5G E are in the 50-90 Mbps range – definitely faster than typical 4G LTE performance.

However, for the average user streaming music or social media videos, 5G E may not feel dramatically different than 4G in day-to-day use. The perception gap comes from how much 5G has been hyped for bringing about amazing improvements to our mobile experience. Those promises don‘t match up with the modest generational enhancements from technologies like 5G E.

Where you may notice a real benefit is with faster downloads, improved streaming quality, and reduced buffering during data-heavy activities like gaming, video chatting, or using augmented reality apps. But for basic needs like web browsing, email, and music, 5G E won‘t radically change your experience.

Looking Ahead to the Future of 5G

While 5G E doesn‘t deliver the full 5G experience, it is laying the groundwork to help transition AT&T‘s network to true 5G connectivity over the next few years. The upgrades bring tangible if modest improvements for today.

However, to get the massive speed boosts, ultra-low latency, and next-gen capabilities promised by 5G, widespread build-out of new high-frequency 5G networks is needed. AT&T along with Verizon, T-Mobile, and other carriers are actively deploying true 5G networks, so coverage will soon expand.

For now, restrain your expectations when seeing the "5G E" icon. But get excited for the future as real 5G arrives! I hope this deep dive has helped explain exactly what you‘re getting – and not getting – with 5G Evolution. Let me know if you have any other questions!
