T-Mobile boosts 5G speeds by combining mid band downloads, low band uploads

Delivering truly next-generation network speeds has been a challenge for U.S. cellular carriers, as their low, mid, and high band wireless towers have thus far required seriously awkward speed and distance compromises. Today, T-Mobile said it has successfully tested the next piece of its 5G strategy: Carrier Aggregation (CA) technology that will dedicate 2.5GHz mid band spectrum to downloads and 600MHz low band spectrum to uploads, simultaneously improving T-Mobile’s 5G speeds and reach across the United States.

In prior cellular generations, downloads and uploads generally shared a single radio frequency, equivalent to wired phone calls that put talking and listening through the same cable. Using carrier aggregation, T-Mobile is enabling a single phone to have separate inbound and outbound radio connections, spanning two radio frequencies that have been synchronized to seamlessly provide service together. This will let T-Mobile’s mid band towers handle outbound traffic at their best speed while slower but longer-reaching 600MHz low band towers take care of uploads, which don’t typically need to be as fast as downloads.

T-Mobile’s announcement has broader importance for businesses and end users, particularly in the United States, as it offers a clear path to widespread adoption of 5G cellular technology. Rival carriers Verizon and AT&T initially launched 5G exclusively using high band millimeter wave hardware that was extremely fast but barely covered individual city blocks, precluding large-scale rollouts. T-Mobile initially responded with a nationwide low band 600MHz 5G network that was roughly as slow as 4G in some places but faster in others. The carrier then augmented its service in some locations with a 2.5GHz mid band layer capable of much greater speeds. Combining those two layers in this fashion gives the carrier — and its rivals — a roadmap for effectively using existing “sub-6GHz” radio spectrum to deliver 5G service across

Indian Startups Band Up Against Google Dominance, Want To Build National Alternative To Play Store

KEY POINTS

  • Google Play will collect a 30% commission on in-app purchases from 2021
  • Indian startup founders called these charges “unfeasible”
  • Google’s Android holds a 95.8% market share in India

More than 150 top Indian startups and businesses, some of them big names, have banded together to challenge Google’s monopoly over the Android app ecosystem in India  and build an app store that the country can call its own, TechCrunch reported.

The move by Indian businesses to to build a national altenative to Google Play was prompted by Google’s recent annoucement to force app developers on its store to use its payments system, which takes a 30% cut on transactions including in-app purchases. Reports said founders of leading startups like Paytm, a payments app simiar to Google Pay and is India’s most valuable startup; MakeMyTrip and PolicyBazaar discussed Google’s policy and the concerns on dependence on Google on a call.

It is not yet clear how far the effort has progressed.

TechCrunch said without naming any sources that dozens of executives “from nearly every top startup and firm” in India attended the call Tuesday and agreed that a Google’s 30% cut was “simply unfeasible” and will hurt Indian businesses. It said the meeting discussed Google’s “monopolistic” hold on India, which has one of the world’s largest startup ecosystems, and what the executives alleged were unfair and inconsistent enforcement of Play Store guidelines in the country by Google.

Last month Google reiterated Play Store’s gambling policy and even pulled Paytm’s app from the store for some time, citing repeated violations of the policy. Google leads the mobile payments market in India, and is a direct competitor to Paytm in
