CDMA is also known as spread spectrum technology because it
uses a low-power signal that is "spread" across a wide
bandwidth. With CDMA, a phone call is assigned a code, which
identifies it to the correct receiving phone. Using the
identifying code and a low-power signal, a large number of
calls can be carried simultaneously on the same group of
channels. TDMA is a digital air interface technology
designed to increase the channel capacity by chopping the
signal into pieces and assi |

The more boxes other guys produced, the more QCOM earns.
This is much easier way to win. In addition, they also
make chipsets. See below:
"QUALCOMM, Inc., a provider of digital wireless communications
products,
designs, develops, manufactures, markets and licenses CDMA subscriber
products, chipsets and system software. For the three months ended

昨天财富杂志(Fortune)对 Verizon CEO Ivan Seidenberg 的采访中确认 CDMA 版本的
iPhone 会在明年早期发布。
The answer: yes. Fortune has confirmed that a Verizon iPhone will be released in early 2011.
关于 CDMA 版 iPhone 的猜测已经很多很多了,但这次是唯一一次被 Verizon CEO 确认的.
种种迹象显示,iPhone 登陆 Verizon 是迟早的事情。甚至有很多网站和分析师都发布了很多有
趣的关于会有多少 AT&T iPhone 用户转投 Verizon 的预测:
Credit Suisse 预测 2011 年会有 1 百 40 万的 AT&T 用户投向 Verizon 的怀

胆,每三个 AT&T 用户中就会有一个倒戈。虽然 AT&T 信誓旦旦的表示失去 i... 阅读全帖 |

I understand China Unicom is the only authorized iPhone distributor in China
, is their 3G network (WCDMA?)
compatible with AT&T or Verizon? I also remember China Unicom sold the CDMA
network to China Telecom,
and both China Mobile and China Unicom has GSM network. |

单从specs上看,是不是买CDMA格式的iphone5合算?如果偶尔拿回国内用的话呢?

CDMA还是锁着,老爸的电话是电信CDMA 133的号,不想换号,不知道拿回去有没有什么
办法能用呢?

Verizon 5s 既支持CDMA,又支持GSM,而且是无锁的。
要买没有合约的V版5s,
请去apple retail store,
跟店员讲你只要“device only”。 |

s****e 发帖数: 720 | 19 Verizon 5S多支持CDMA, 不知道有什么用?
回国用的话,插个sim卡多方便,用CDMA应该比较麻烦。
美国这边用ATT或tmobile也没用。
现在在t-mobile,正在考虑买tmobile或verizon的5s。好像我在官网上买
t的5s,现在的plan $5off,而且可以选择$15 2GB的data。 |

e******n 发帖数: 3435 | 23 其实和插不插卡没有必然联系,最重要的是有没有相应的硬件支持。ATT tmo的iPhone
没有CDMA模块,所以不能用CDMA。 |

M**********e 发帖数: 44 | 29 我对CDMA的convolutional encoder的标准不熟悉,只知道K=9,2个branch and
polynomial generator.
CDAM或LTE中对convolutional encoder的throughtput要求最高是多少?编码一个比特需
要多少纳秒?CDAM或LTE还有那些速率?
比如802.11a中的最高速度:54Mbps:216 bits are needed to be processed in 4us,
so the throughput is: 18.5ns/bit.
我在做个多模式下通用的Viterbi decoder,可以支持802.11a和MBOA UWB,想把CDMA也加
进去. |

标 题: GSM vs CDMA difference still matters on voice service?
发信站: BBS 未名空间站 (Sun Aug 25 13:06:11 2013, 美东)
is the GSM CDMA difference only specific to data signals, or also meaningful
to voice signals ?
