AT&T has announced the very limited deployment of 5G services in 12 cities.

Starting Tuesday, what AT&T is describing as “select businesses and consumers” in Atlanta, Charlotte, Dallas, Houston, Indianapolis, Jacksonville, Louisville, Oklahoma City, New Orleans, Raleigh, San Antonio, and Waco will receive a free Netgear Nighthawk mobile hotspot that will let them access AT&T’s seminal 5G network infrastructure.

Starting in the spring, AT&T said, a broader swath of customers will be able to buy the Nighthawk for $499 and pay another $70 a month for 5G service capped at 15 gigabytes of data usage.

AT&T said it is using the high-frequency “millimeter wave” spectrum in what it is branding as its “5G+” service. AT&T pegs peak theoretical speeds for the service at around 1.2 Gbps. Demoing the technology earlier this month at the Qualcomm Snapdragon Technology Summit in Maui, however, 5G+ topped out at only around 140 Mbps.

This is a sizable improvement over 4G LTE speeds—around three times faster—but it’s not by any means a gamechanger in terms of the quest to turn 5G into a replacement for fixed wireless.

AT&T also plans to expand its 5G+ offering to Las Vegas, Los Angeles, Nashville, Orlando, San Diego, San Francisco, and San Jose. Verizon also conducted a limited launch of a proprietary network technology it’s calling 5G back in October. T-Mobile plans to launch a 5G network in 30 cities next year.

Notably, Samsung said it will debut the first 5G Galaxy smart phone in the first half of 2019.

“This is the first taste of the mobile 5G era," said Andre Fuetsch, president of AT&T Labs and chief technology officer. "Being first, you can expect us to evolve very quickly. It's early on the 5G journey and we're ready to learn fast and continually iterate in the months ahead."

IRVINE, CALIF.—Pasternack has released the PEM010, a complete millimeter wave transmitter module for use in the development of multi-gigabit, high-speed, point-to-point wireless communication links. These communication links provide gigabit wireless throughput for a variety of applications involving telecommunications “last kilometer” distribution, telecommunications cellular backhaul, millimeter wave wireless gigabit Ethernet data communications, building-to-building high speed networks and mesh-based LAN infrastructures.

Pasternack’s new model, PEM010, is an integrated millimeter wave transmitter (Tx) module that operates in the global unlicensed frequency spectrum from 57.0 to 64.8 GHz. It also supports IEEE 802.11ad and 802.11aj Wi-Fi protocols for wireless, multi-gigabit, high-speed networking. This module’s design incorporates a silicon germanium (SiGe) MMIC-based frequency synthesizer and power amplifier. Its aluminum package is precisely machined and features a complete waveguide interface with low-loss transition between the chip and WR-15 waveguide port. A multi-pin ST4 connector is used for power, reference clock, digital control port and baseband signals.

Typical performance of the PEM010 includes 38 dB gain, +12 dBm output P1dB, 34 dB image rejection, up to 1.8 GHz modulation bandwidth, and Phase Noise of -111 dBc/Hz @ 10 MHz offset. Either of the two reference clocks can be used for setting the 540 MHz or 500 MHz channel spacing.

This module’s I/Q analog baseband interface accepts analog baseband signals, which provides flexibility in design and applications. The optional baseband input supports FSK/MSK modulation for non-coherent applications and the WR-15 waveguide port can support available gain horn antennas for extended transmission range applications.

Pasternack’s PEM010 Tx module is in-stock and ready for immediate shipment with no minimum order quantity.
