Four months for DNA results, still waiting. I had a DNA kit sent to my BIL for his birthday in August. He spit, sent it off, and 10 weeks later was informed that it didn't work so they sent him a new kit.It has now been 9 weeks since the lab received his second spit, no results.our months for DNA results, still waiting.

Code division multiple access (CDMA) is a channel access method used by various radio communication technologies.CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel.This allows several users to share a band of frequencies (see bandwidth).DMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel. This allows several users to share a band of frequencies (see bandwidth).
TDMA characteristics. 1  Shares single carrier frequency with multiple users. 2  Non-continuous transmission makes handoff simpler. 3  Slots can be assigned on demand in dynamic TDMA. 4  Less stringent power control than CDMA due to reduced intra cell interference. 5  Higher synchronization overhead than CDMA.
