RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Anatech Electronics, a manufacturer of RF and microwave filters, has published its March newsletter. In it, Sam Benzacar notes the impressive of rapid transformation of T-Mobile from virtual insignificance in the wireless world to the top of the hill. He cites Open Signal's January 2018 report titled, "State of the Networks: USA" as evidence. Sam offers his take on the reason for T-Mobile's success and for why Verizon and AT&T fell behind. As usual, it's a worthwhile read.

And the Winner Is: T-Mobile, for Now

By Sam Benzacar

Five years ago, no one would have through that T-Mobile would be a major cellular player. But in what is possibly the biggest positive turnaround in the history of this business, T-Mobile has risen from third-tier status to become a first-tier player. Even disregarding the T-Mobile CEO's aggressive Elon Musk-style marketing, Open Signal's "State of the Networks: USA" report released in January confirms it.

In case you haven't heard of Open Signal, the company was founded in 2010 to measure mobile network performance by collecting and analyzing user data from all over the world. About 2 billion measurements are made every day. For example, to produce this report, 5.9 billion data points were analyzed from 237,213 devices spanning October 1 to December 30, 2017. By the way, Open Signal's reports are extremely informative if you're interested in following this industry.

In every report, the company awards winners in six performance categories:

  • 4G download speed
  • 3G download speed
  • Overall download speed
  • 4G latency
  • 3G latency
  • Availability
The results this time aren't what you'd expect: T-Mobile won in every category but 4G latency (AT&T took the honors there). That said, the differences in some metrics between T-Mobile and Verizon were almost identical, with T-Mobile gaining the edge by a hair, and the "winner" varied by region. Still, this means that T-Mobile has risen dramatically: In its August 2017 report T-Mobile won in every category, and in its February 2016 report, Verizon and T-Mobile tied for fastest 4G speed, Verizon had the greatest 4G availability, and Sprint had the lowest 4G latency.

My point here is not that everyone should immediately jump ship and moved to T-Mobile. Rather, it shows how fierce the competition it is between T-Mobile and Verizon and how AT&T (once the only other major carrier) has fallen behind and stayed that way. It also demonstrates what happens when carriers make a massive change in their pricing plans. Verizon and AT&T bit the bullet early last year and reintroduced their unlimited data plans to keep pace with T-Mobile and Sprint.

As soon as they did that their 4G speeds dropped precipitously and continued to do so until September, the inevitable result of users availing themselves of more data. By the end of the year, both AT&T and Verizon had recovered. It wasn't the first time this happened, and it won't be the last, as the cellular industry move to its fifth generation, which will be even more competitive.


What's News...

Miniature Drone Radar

Boeing is providing $15 million in funding for Fortem Technologies that sells a small detect-and-avoid radar system for drones called TrueView, the radar is designed to help UAVs detect and avoid other airborne objects beyond visual line of sight. It will be required for applications like drone-based delivery systems, air taxis and assorted other planned uses for the technology. TrueView can simultaneously track thousands of objects down to below the size of a soda can over a 360-deg. field of view. The system weighs only 1.5 lb. And consumes little power.

Pennsylvania May Let Cops Use Radar

Pennsylvania is the only state that does not allow municipal police officers to use radar. The ban, which went into effect in 1961, was designed to keep small towns from abusing it. However, Rep. Greg Rothman has introduced a bill that will eliminate the ban but also impose restrictions on how radar can be used. Any officer using radar must complete a training course, roads entering towns must be marked with "radar enforce" signs, and tickets can't be issued unless the speed is 10 miles an hour over the limit. If any town generates more than 1% of its total revenue from radar traffic fines, and offending motorists can't be prosecuted. In addition, no quotas can be said, and annual reports must be submitted to the state every year.n. on, 10-min. off increments for more than nine hours each day.


Qorvo Sets New Benchmark

Qorvo just set a new benchmark for GaN-on-SiC RF transistors with its QPD1025 HEMT that delivers 1.8 kW (pulsed) at 65 V between 1 and 1.1 GHz that is designed for L-band avionics and IFF applications. The device delivers gain of 22.5 dB and power-added efficiency of 65.7% at 3-dB compression when tuned for power and 77% when tuned for efficiency. Maximum VSWR is 10:1 at 3-dB compression. Although the device has an extremely narrow bandwidth, so do the avionics systems it's designed to operate in.


Egypt's EW Systems Jam Israeli Mobile Phones

As Egypt fights insurgents in the Sinai, its EW systems have been jamming not just the insurgents but mobile phone service in some places in Israel and the Gaza Strip. Cairo launched a major sweep of Sinai jihadis loyal to Islamic State in February and began jamming mobile phone frequencies in Sinai. The goal was to disable the communication abilities of insurgents who have been suspected of using stolen Israeli SIM cards close enough to the border to link up with Israeli cellphone reception. Gadi Yarkoni, a mayor representing Israeli communities near Gaza, criticized the Israeli communications Ministry and threatened to sue the phone companies, saying the failure to fix disruptions "shows disrespect for the residents of the Gaza periphery."
