Big ambitions for next gen satellite networks – part 2

While SpaceX is planning to encircle the planet with thousands of satellites for delivering broadband Internet access, another venture, known as Ligado Networks, has come up with a plan to salvage the power of the largest commercial satellite ever launched to deliver connectivity over North America for the growing Internet of Things (IoT) sector, and possibly as a boost for 5G networks.

Ligado Networks is a privately-backed company based in Reston, Virginia, with investors including Centerbridge Partners, Fortress Investment Group and JPMorgan Chase & Co. From the big hitting industry execs on the leadership team it is clear the company is serious. Ivan Seidenberg, a former chairman of Verizon Communications, serves as chairman. Also on the board of directors is Timothy Donahue, former executive chairman of Sprint Nextel and former president and CEO of Nextel Communications, and Reed Hundt, the former Federal Communications Commission. Doug Smith serves as Ligado's president and CEO; he is known for his work in engineering and launching nationwide networks for GTE, Nextel, Sprint Nextel and Clearwire.

Picking up the pieces from LightSquared, SkyTerra and Mobile Satellite Ventures

Ligado Networks, previously known as LightSquared, emerged from bankruptcy reorganisation in 2016 with a new plan, or rather a new version of an old plan. The company controls 40 MHz of nationwide spectrum licenses in the L-Band (1500 to 1700 MHz), which it acquired in 2010 through its purchase of SkyTerra, another bold start-up that envisioned transforming the U.S. mobile scene with satellite communications.

Prior to 2008, SkyTerra was known as Mobile Satellite Ventures and had successfully operated the MSAT-1 and MSAT-2 satellites for over a decade. As 4G LTE technologies neared, the company set its sights and going big. The business plan evolved from pure mobile satellite to a hybrid design where the satellite connectivity would be used to augment terrestrial mobile communications. This would mean using the same spectrum bands from ground based base station as well as from the satellite. The company changed its name to SkyTerra and was acquired by Philip Falcone's Harbinger Capital Partners acquired SkyTerra in March 2010. Harbinger invested about $2.9 billion in assets and soon raised more than $2.3 billion in debt and equity financing.

SkyTerra soon became known for its massive SkyTerra 1 satellite, which weighed a record 6,910 kg. The satellite was built at Space Systems/Loral's Palo Alto, California facility. It operates in two 10 MHz blocks of contiguous MSS spectrum in the 2 GHz band throughout the U.S. and Canada. Notably, the satellite uniquely features an 18-metre reflector and an S-band feed array with 500 spot beams. In November 2010, SkyTerra 1 was successfully launched from the Baikonur Cosmodrome in Kazakhstan.

SkyTerra changed its name to LightSquared and in January 2011 was granted a conditional waiver by the FCC to test its network if it could be shown that the service would not interfere with GPS signals. This alarmed many GPS advocates, who argued that the L-band spectrum was simply too close to its own and that even a little interference could have serious consequences for the military, aviation, agriculture and other vertical sectors that rely on precise navigation.

In February 2012, the company received its greatest setback when the FCC withdrew its conditional approval for LightSquared network due to the potential interference concerns with GPS receivers. In June 2012, the U.S. Securities and Exchange Commission filed securities fraud charges against Philip Falcone and Harbinger Capital Partners; the case was settled in June 2013. For LightSquared, the game was over and it was soon forced into the bankruptcy courts. In addition to the technical, legal and financial challenges, LighSquared also faced allegations of political favouritism. Nevertheless, it still had the spectrum licenses and a fully functional Skyterra1 satellite parked in geostationary orbit.

Ligado Network is the new entity that in December 2015 emerged from this decade-long mess. Significantly, the company reached a settlement with the GPS industry on a technical plan to avoid interference issues by reducing the transmission power. It is not clear why a similar compromise could not have been reached in 2012. Ligado is now awaiting clearance from the FCC.

Ligado looks for its market

So back to square one, and Ligado Networks is now moving ahead with the plan to combine Skyterra1 satellite coverage with a ground-based network should FCC approval come. The goal is a ubiquitous national network whose footprint requires far fewer ground-based towers than would otherwise be required for universal coverage. The company says its mid-band spectrum is well suited for things that move, such as planes, trains and automobiles.

In its original iteration, LightSquared aimed to either compete with or partner with 4G LTE mobile services. At least one mobile handset model was developed that incorporated specialised silicon for tuning in the L-band frequency in addition to standard cellular bands. It seemed that a distribution partnership with AT&T was also in the works. For consumers, this would have meant being able to use the AT&T LTE network where available and then seamlessly roam onto the SkyTerra1 satellite service when that signal was stronger. Unfortunately, this handset was based on an old Nokia design and was not an iPhone or Android device. Even without the legal and financial issues, this business plan was not going to work.

Meanwhile, as the number of autonomous vehicles on the road rises, the strain on the mobile infrastructure will rise. Mobile operators are working to 'densify' their networks in preparation for 5G. This might mean more of the capex is focused on the cities and less on rural places. Satellite coverage could really help here, although the issue of latency may prove problematic for fast moving vehicles needing to connect to a geostationary bird. In addition, there is the issue of creating end-point devices tuned for the L-band spectrum. Perhaps Ligado will introduce specialised solutions for the types of vehicles it is targeting. A further issue to consider is the aging Skyterra1 satellite. It has now been in orbit for six and a half years, and most satellites are designed for a 15-year life. By the time the Ligado Network is up and running it may be approaching mid-life status and time to start planning a new one.

Analog Devices updates RadioVerse to support transition to 5G technology

Analog Devices (ADI) has announced an update to its RadioVerse technology and design ecosystem, which is intended to simplify and accelerate radio development for wireless carriers and telecom equipment manufacturers as they transition cellular base stations from 4G to 5G technology.

ADI's expanded RadioVerse portfolio features new radio transceiver hardware, software tools and a robust design environment designed to enable the more compact and lower power radios required for next generation networks. The new solution allows customers to evaluate and develop radio designs for 4G small cell and Pre-5G massive MIMO systems, which will be key elements in the transition to 5G.

Supporting radio design across the circuit, architecture, system and software levels, the updated RadioVerse release includes the AD9375 RF transceiver, the latest addition to ADI's integrated wideband RF transceiver series. The AD9375 device is claimed to be the first RF transceiver to incorporate digital pre-distortion (DPD) algorithm on-chip to help reduce DPD power consumption by up to a claimed 90% versus competing solutions.

ADI stated that re-partitioning the DPD system from the FPGA to the transceiver reduces the number of JESD204B serial data interface lanes by half, resulting in a significant power saving, particularly as the number of antennas per base station increases from two to 128 in support of Pre-5G massive MIMO radio-channel density requirements.

Further benefits of the new design include a more compact radio circuit layout enabling simplified routing and system design, reduced base station size and allowing the use of lower-cost, less complex FGPAs. Applied to small cells, these advantages can allow more frequency bands per cell for higher network capacity.

ADI's AD9375 transceiver allows a common radio platform design that is tunable over a range of 300 MHz to 6 GHz, operates on a 6 Gbit/s JESD204B interface and consumes less than 5 Watts. As with the AD9371 product, the AD9375 features two 100 MHz receivers, two 250-MHz transmitters, a two-input observation receiver and a three-input sniffer receiver. In addition, integrated DPD can support 3G and 4G waveforms with instantaneous signal bandwidth up to 40 MHz.

In addition to the AD9375, the RadioVerse transceiver hardware portfolio features wideband devices for base station architectures ranging from macro- to pico- and femto-cell form factors, in addition to ultra-low power, narrowband transceivers targeting industrial Internet of Things applications.


ADI noted that it is continuing to expand RadioVerse through partnerships with power amplifier (PA) suppliers including NXP Semiconductors and Skyworks Solutions.
