NEW POSSIBILITIES

Our radio performance is unlike anything anyone’s ever seen. 
It follows that imagining the possibilities of what you might do with it requires some helpful illustration.

Through deep engagements with tier 1 operators all over the world, each of the unprecedented performance improvements achieved by Tarana technology noted on our platform page has been extensively validated.  To help you get a tangible sense of the new possibilities we can enable in a wide range of access and backhaul applications, we offer you here a gallery of noteworthy deployment and field trial highlights, organized by the key radio-performance challenge addressed:  obstructions, self interference, unlicensed-band interference, distance, and motion.

OBSTRUCTIONS

NLoS in Manhattan

33 dense urban sites up to 3km distance with typically severe obstructions.  3.65 GHz.

One of our most extensive and impressive early field trials of NLoS range and performance was conducted with a tier-1 US mobile operator in Manhattan.  We mounted our base unit, which we call a concentrator node (CN) on the top of the Federal Building in lower Midtown.  The remote unit, our edge node (EN) was mounted on the back of an SUV, deep within the changing RF environment at street level.  Our operator host directed us to a series of 33 different locations, most chosen on the fly, throughout lower Manhattan.  Because of the continuous adaptation of the system, the EN had re-established a full-rate link in most cases by the time we put the SUV in park, with zero physical re-alignment.

 

Manhattan NLoS Results

Aggregate UL and DL capacity per link vs. line-of-sight distance from CN to EN for 33 locations (all in 20 MHz channel at 3.65 GHz)

This data set clearly confirms the quality of our multipath handling; our system performed at full rate at 90% of the locations within a 2 km radius of the CN and achieved connectivity on 100% of them.

 

Extreme NLoS

Two compelling examples from Manhattan NLoS testing

Some of the NLoS links tested were quite extreme, as shown in these two examples (both in 20 MHz channel at 3.65 GHz).  At the end of the testing, our host concluded, “This product is magic!”  Confirmation of our rapid self-alignment capability was an added bonus — our host reported that links we connected automatically in a couple minutes had taken prior teams (using conventional radios) hours to attempt, with staff on both ends, and in most cases without any success.

 

NLoS in Hong Kong

100 Mbps at 1.2 km in 40 MHz 5.8 GHz extreme-NLoS channel

Recent exhaustive testing with one of the leading mobile operators serving Hong Kong in another batch of extreme NLoS conditions led their CTO to report to his fellow executives that “Tarana’s technology is outstanding.  And you guys know I don’t say that word very often.”

 

Modeling NLoS Propagation

Analysis with Siradel’s ray-tracing tool shows clearly how NLoS connectivity is achieved

Beyond a nice CTO endorsement, we’re including this Hong Kong link in the gallery because we also used Siradel’s new S_5G Connect tool to analyze link performance in parallel with the real-world testing.  Its visualization of the propagation paths from CN to EN help take the mystery out of how NLoS works.  It’s not about penetrating through buildings and other obstructions, it’s about using diffraction over the top of them and reflections around them.  The Siradel tool’s prediction of throughput was accurate to within a couple % on all the links tested, an indication of its utility for pre-deployment validation wherever detailed building and clutter data are available.

 

NLoS in Greece

Creating new possibilities for radio backhaul in dense-urban central Athens (115 Mbps at 223m in 20 MHz at 3.5 GHz here)

SCROLL RIGHT TO SEE FULL LINK

The radio access network team in Greece for our soon-to-be-named tier 1 European fixed/mobile operator was facing challenges for cell densification in central Athens.  We showed them new options through a number of link tests and deployments pictured here, highlighting that reliable high bandwidth could be achieved, in both 3 and 5 GHz, in places they never thought possible.

 

Athens Urban NLoS 2

186 Mbps (full rate) at 333m in 20 MHz at 3.5 GHz

 

Athens Urban NLoS 3

186 Mbps at 315m in 20 MHz at 3.5 GHz

 

Athens Urban NLoS 4

102 Mbps at 342m in 20 MHz at 3.5 GHz

 

Athens Urban NLoS 5

186 Mbps at 219m in 20 MHz at 3.5 GHz

 

Extreme Urban NLoS in Montreal

53 Mbps at 815m (1,137m RF distance, the length of the primary RF path).  CN at 26m AGL, EN at 2m

Validation with tier 1 fixed and mobile operator in Canada.  This is the location their engineering team picked to see if they could break AA2 (sorry, guys, you’ll have to try harder than this).  Credit to our Canadian partner Gap Wireless.

 

Urban NLoS Event Support

100 Mbps in 20 MHz at 3.65 GHz, with 800m line of sight but 1.4 km RF distance

Etheric Networks’ TV station customers needed reliable, high-bandwidth connectivity for remote trucks at street level for the annual Chinese New Year celebration in San Francisco in February, 2017.  Etheric’s closest POP was several blocks away, and line of site from that rooftop to Union Square was well blocked.  Tarana made that happen nonetheless, delighting all involved.

 

Suburban NLoS

50 Mbps at 3.5 km (4.6 km RF distance) in 20 MHz channel at 5 GHz with multiple building obstructions in LoS.  CN at 9m AGL, EN at 3m

Suburban NLoS with Foliage

170 Mbps at 300m in 20 MHz channel at 5 GHz, with multiple buildings and dense foliage obstructing LoS.  CN at 10m AGL, EN at 2m

SELF INTERFERENCE

Concentrated Multipoint (CMP) Spectral Efficiency in Montreal

Aggregate capacity of 381 Mbps in 3 simultaneous streams over severe NLoS links, all in the same 20 MHz channel at 3.5 GHz

Validation with tier 1 fixed and mobile operator in Canada, showing our unique ability to manage self-interference within a point-to-multipoint configuration such that three simultaneous, independent streams can be maintained in the same channel from one base unit.  (Credit to Gap Wireless.)

 

CMP Spectral Efficiency in Montreal 2

342 Mbps aggregate capacity on 3 simultaneous NLoS links at ~650m despite small angles of separation

Since the previous example looked to our Canadian operator like a relatively easy configuration for self-interference management (with the buildings providing some inherent separation between streams), they also explored our performance when all the ENs were close together and close to line of sight (with a nearly impossible 1.2° and 2.0° of angular separation between links 1 and 2 and  2 and 3, respectively).  That we could nonetheless maintain three simultaneous links in this relatively low multipath situation illustrates what we mean by precision when we note precision digital beamforming as one of our core capabilities.  (Credit to Gap Wireless.)

 

CMP in Montreal 3 — Suburban

548 Mbps aggregate throughput in a single 20 MHz channel in 3.5 GHz, for 3x 300 to 700m NLoS links (98% of full capacity)

After the challenges of urban Montreal, our Canadian operator took us to the leafy, surburban setting of Souers Island, where we continued to show unrivaled PtMP performance in the face of foliage as well as building obstructions.  (Credit to Gap Wireless.)

 

CMP in Montreal 4 — More Suburban

359 Mbps aggregate throughput (for 2x 1,200m links) in 20 MHz channel at 3.5 GHz (96% of full capacity)

Multi-Cell Performance in Silicon Valley

3 CNs and 9 ENs in 1 square km, all in the same 20 MHz channel, maintaining 90% of full rate on all links

We’ve conducted extensive multi-site validation of our co-channel interference management, cell-edge performance, and spectrum multiplication capabilities with a tier 1 customer in Silicon Valley.  The tests — which required nontrivial resources to conduct, but are really the only way to tell how a system will perform in a network of co-channel cells — involved 3 CNs and 9 ENs in close proximity.  We maintained 90% of the configuration’s full 187 Mbps/link data rate throughout the network, and capacity density of 128 bps/Hz/km2, roughly 25x what LTE can deliver today.

 

UNLICENSED INTERFERENCE

To combat unmanaged interference in unlicensed spectrum, current wireless systems offer nothing more constructive than channel-changing in one form or another — which operators consider an inadequate, unreliable response in an environment where usage in all available unlicensed channels continues to rise.  To solve this problem, we invented a whole new approach to handling unlicensed-band interference, leveraging our multi-antenna processing and extremely talented team, that creates immunity to interference in the current channel.  One of our tier 1 operators in Europe is very excited about how this enables “free-of-charge spectrum” for mobile radio backhaul and other applications.  We’ll be sharing more details about this in the coming weeks.  As a placeholder, we can show a couple highlights of the results.

 

Interference Immunity and NLoS in San Francisco 1

172 Mbps at 447m, 20 MHz NLoS channel, 5.8 GHz, 10 dB interferer-to-signal ratio (i.e. -10 dB SINR).  CN at 18m AGL, EN at 3m

We know from reports of tier 1 operator testing of other solutions in San Francisco that the city’s interference in 5 GHz is extremely challenging.  We’ve shown that our interference-cancellation technology is up to that challenge — delivering nearly full-rate performance on NLoS links across multiple city blocks, even with negative SINR.

 

Interference Immunity and NLoS in San Francisco 2

50 Mbps at 546m (803m RF distance) with severe NLoS.  Same channel and interference conditions as above.

 

DISTANCE

While we generally advise that our NLoS capability works well within about 2 km, that’s just a rule of thumb to use when you have no specific information about actual channel conditions.  Once you’re looking at a real link application, the more actionable guidance is that we can deliver our lowest modulation class (16 QAM) with just a little over 150 dB of pathloss, and our highest mod class (256 QAM) at about 135 dB of pathloss.  For links with less extreme obstructions, you can get (potentially a lot) more distance, as the following examples show.

 

Remote-Site Connectivity in Oil and Gas

Application validation with leading global petroleum company

To confirm our solution to their remote-site connectivity problems, our OilCo tested AA2 performance from a 105m tower to a range of remote sites in a Texas oilfield, from 11 to 58 km away.  They needed a solution that would give them reliable connectivity despite challenging terrain, unskilled installers, and low AGL at the remote sites.  Our radios met all their requirements, and they are operationalizating AA2 now.
