"We’ve all experienced the expanding cell phone system’s shortcomings, from dropped calls to no service to a slow Internet connection. When one of those things happens, chances are it’s because too many people are crowded into one area. Poor service due to crowding is most apparent at concerts or other large events, but it’s becoming an everyday occurrence as more people use more connected devices"

Cupertino has a worker population of 32,000 and only 20,000 households.

Apple Campus 2 will add 14,000 and Vallco will add another 10,000 workers, just from office alone.

This will increase the working population in Cupertino by 50%.

Thus, the demand for cell signals will increase by 50%.

People are already experiencing dropped calls when going to crowded areas in Cupertino.

Please study the impact on existing cell signals in all carriers.

If more cell towers are needed, please install them far away from schools to reduce any potential health impact on children.

The increase of 3.5 million s.f. of office and 2 million s.f. at Vallco and 260,000 s.f. in Main Street would total 5.76 million square feet, which is over 50% of total office space in a short time.

Please study the impact on the capacity of high speed internet and cable services from such a large capacity increase.

Please study the impact on internet speed and reliability of signals for other home users when a large population nearby might eat up all internet bandwidth.

Note that many companies do have employees who work longer hours until 8, 9 or 10 o'clocks.

 

Please study the impact from 3pm to 6pm when many school children need to use internet to do school homework as more and more school homework is now done online.

Please study the impact during early evenings when the residence population and also school-aged children need access to internet for either entertainment or homework.
