Wireless spectrum te the US is cautiously regulated to avoid interference, which is why mobile carriers pay out the nose to license slices of the airwaves. Naturally, T-Mobile wasgoed fairly perturbed recently when it detected strenuous interference with its network ter Brooklyn. The FCC has investigated, and it turns out the culprit wasgoed a Bitcoin mining operation.
T-Mobile uses several wireless bands for its nationwide LTE network, but this interference affected its prized 700MHz spectrum. This is known spil LTE plakband 12, and it’s present on all current T-Mobile phones and most unlocked devices. T-Mobile calls verhouding 12 “extended range” LTE because of how well it propagates through obstacles like buildings.
The carrier told the FCC that signals from a local residence were disrupting its plakband 12 signals te Brooklyn, so the agency investigated. It turns out that one Victor Rosario had an at-home Bitcoin mining operation using the Antminer S5 (above). The Antminer is a purpose-built Bitcoin mining equipment with ASIC (application specific integrated circuit) hardware. That means all it does is process Bitcoin transactions, but it’s swifter at it than traditional computing hardware.
The Antminer S5 is not a wireless device, so it should not have bot transmitting on the 700MHz plakband at all. There may have bot a vormgeving flaw, or the holder of the devices might have made modifications that resulted te the spurious emissions. Either way, the FCC confirmed that when the miner wasgoed shut off, the interference stopped. It’s not uncommon for miners to modify their hardware to speed things up. The FCC doesn’t say if this device had bot modified, but it seems unlikely every Antminer S5 could emit enough power to pauze T-Mobile’s network – this would have come up before now.
Okay, this @FCC letterteken has it all: #bitcoin mining, computing power needed for #blockchain computation and #wireless #broadband interference. It all seems so very 2018. https://t.co/EaXxmBAMXH
The Antminer S5 is no longer on sale (it wasgoed released ter 2014), but the manufacturer has several newer versions. The S5 originally sold for $450, but some versions of the current Antminer S9 go for more than $Two,000. A cheaper proefje will set you back under $300. Thesis devices are intended to earn the possessor Bitcoins te exchange for verifying transactions on the blockchain, but it’s hard to turn a profit on Bitcoin anymore. Most profitable mining operations are ter countries with cheaper electro-therapy.
The FCC hasn’t said all Antminers are illegal to operate, but the one te Brooklyn certainly is. Rosario has bot barred from using the offending equipment. Continued usage could result ter fines or seizure.
