Qualcomm has bullied players like Samsung to prevent them from using their own LTE modems, and has done everything possible to ensure they are the only reasonable choice for LTE chipsets.
In Samsung's case, only Samsung branded devices can have their LTE modem per the settlement with Qualcomm, and US bound phones always ship with a Qualcomm SoC (part of that whole home territory thing for Qualcomm).
Another affected group is Mediatek, they only recently got LTE support, and their ability to get chips with LTE is entirely controlled by Qualcomm. There is no competition in the modem space, which is absolutely appalling.
- gliderecord 8y agoBecause they were the inventors of 4G LTE.
- monocasa 8y agoSo? They have to make the patents available under FRAND terms in order for it to have become 4G, but are clearly not.
- selectodude 8y agoNo they weren’t. NTT DoCoMo and Ericsson did the heavy lifting on it. Qualcomm owns patents on OFDM that they received when they bought Flarion in 2006. They saw an ability to corner the patent market like they did for CDMA and took it.
- wbl 8y agoAnd parents are transferrable. OFDM was huge and important. Without it multipath becomes a problem. Shouldn't the inventor get some value?
- selectodude 8y agoOFDM was invented at Bell Labs in the early 1960s. Anyway, one of their most litigated patents is as follows. >In a data communication system capable of variable rate transmission, high rate packet data trans- mission improves utilization of the forward link and de- creases the transmission delay. Data transmission on the forward link is time multiplexed and the base station transmits at the highest data rate supported by the for- ward link at each time slot to one mobile station. The data rate is determined by the largest C/I measurement of the forward link signals as measured at the mobile station. Upon determination of a data packet received in error, the mobile station transmits a NACK message back to the base station. The NACK message results in retransmission of the data packet received in error. The data packets can be transmitted out of sequence by the use of sequence number to identify each data unit within the data packets. That's the entire thing. No math, no "show your work". Just that paragraph.
- zerohp 8y agoNo that is not the entire thing. That's just the abstract. The patent makes 63 claims. Claims are the only part of the patent document that matters for litigation.
- yogrish 8y ago“Qualcomm bullied Samsung” you got to be kidding. Samsung has internal Modem team working hard to replace QC chipsets, but never successful wrt performance, it was pathetic. So Samsung took approach of using QC chipset in premium market segments and dumped their own modem chipsets in countries like India, Korea.
- StudentStuff 8y agoThat is the narrative we have been fed, but when a company purposefully purloins the highest volume, highest profit market and force all phones sold there to provide your company significant royalties, its unsurprising said company can afford many more of the brightest minds to push the bleeding edge of technology. In spite of this, Samsung has persisted in pushing forward their own LTE chipset, despite the significantly hobbled ROI caused by Qualcomm's actions on such a chipset.

- batiudrami 8y agoThe reasoning I have heard for Samsung handsets shipping with Qualcomm chips in the US is the need to be compatible with legacy CDMA networks (which is the patent issue). Flagship Samsung handsets everywhere except the US and China ship with Exynos SOC.
- yogrish 8y agocan I know why i am being down voted. I gave the information that I am familiar with.
- gsich 8y agoBecause it's wrong?

- vectorEQ 8y ago:') ofcourse apple and all the other tech giants out there do nothing of this sort..
