Prior to 2168 The Daedalus-class ship USS Essex NCC-173, under the command of Captain Bryce Shumar and First Officer Steven Mullen, is caught in an electromagnetic storm and destroyed above the class M moon of the planet Mab-Bu VI. There are no survivors of a crew of 229 (TNG: "Power Play").
Around 2168 The starship Horizon visits Sigma Iotia II. A book called Chicago Mobs of the Twenties is left behind which serves as a model for the planet's new society. Briefly after leaving the ship is destroyed, and it takes 100 years for the sublight distress call to reach the Federation (TOS: "A Piece of the Action").

This indicates that transporter technology is fairly new at this time.
Harry Kim's ancestor Jack pilots a deep space mission to Beta Capricus, while
the rest of his crew is in stasis. When he finds no sign of life he turns around
without waking up the crew. The ship didn't yet have a subspace transmitter
It doesn't make any sense that sleeper ships should have been still in use at that time. With probably ten of thousands of unexplored systems at a reasonable distance, why should one keep the crew in stasis while the ship may be passing possibly much more interesting, inhabited places than the destination, which was obviously the case here? Aren't woefully more advanced ships like the Daedalus (or NX-01) exploring space for already more than half a century? Who would volunteer for such a miserable mission? Moreover, since Enterprise we know for sure that subspace transmitters have existed as soon as 2151.

We may believe the official date of 2245 suggested by Gene Roddenberry. The quote that the Enterprise should be only 20 years old (as of 2285) from "Star Trek: The Search for Spock" is inconsistent with the events in "The Cage" and should be disregarded.
