Who is the founder of cell phone?
It was Invented by a Science Consultant for Star Trek who at the time worked for what is now simply known as BT.
Related Information:
The first Mobile phone Invented was used as a Prop on Star trek the Voyage Home.
It consisted of a bunch of Radio Valves mounted on piece of wood linked in parallel cross linked through a set of amplifier valves and flip-flop valves (transistors), the amplifier valves were on a separate piece of wood and the flip-flop valves were also on a separate piece of wood. The Flip-flop valves worked to modulate the signal, and the amplifier valves worked to change the amplitude of the signal the radio valves determend the frequency.
The three rows of valves were connected to a Cathode Ray Tube which was powered by Car Batteries linked in series run though an inverter. (converts AC to DC and the other way round too depending on how it is wired)
It holds the record for being the biggest Mobile Phone ever. The following year voice capability was added to it. If it was to go on the market or up for auction it would sell for over $500 million.
How do you send text from a mobile phone to an email address?
Instead of sending a txt, click on contact and it should give you three options: picture mail, txt, or email, click on email, enter the email address and send. Hope this helps. <><
Can you unlock boost mobile phones to use with virgin mobile?
The answer to that question is Possibly, and No. Half of the Boost Mobile phones use IDEN radios (Integrated Digital Enhanced Network). The phones are easy to identify- they have Direct Connect (the "chirp"). These CAN NOT be used on any service but Boost Mobile, or if unlocked, Nextel (Or Telus in Canada). The other half of the Boost Mobile Phones use CDMA radios (Code Division Multiple Access), and could feasibly be unlocked to be used with Virgin Mobile. Whether Virgin Mobile would choose to allow them on the network is a whole additional answer (doubtful), but the technology technically would work.
Why is a cell phone important?
cell phones are important because you can talk to family and Friends from a far distance. If you are lost and don't have a car you can call your family or someone you know to come and get you If you want to go some where with your friend, you can call her/him or text her/him on your phone, you wont have to go to her/his house and and tell her/him. That is why cell phones are important
How do you stop somebody from emailing to your cell phone?
LOL this is funny...but u can simply hit that person may be :D or may be send him something which could shut his mouthor rather stop his fingers from emailing..;)
How can you see Deleted text messages from a Boost cell phone?
You can not see them once they have been deleted. They are gone for ever. I suggest that in future you read through what you are going to send and make sure it is alright before you send it.
How do you build a cell phone blocker?
First of all, the legality of cell phone blockers (jammers) is different from country to country. For instance, they are illegal in the United States. They are covered by Communications Act of 1934, as well as property theft laws (since people pay to send and receive these signals). You can get an $11,000 fine, along with some other unlovely things.
You build a jammer by creating a signal of the same frequency with enough power to cancel out the other signal. If the two signals are the same, they will collide and cancel.
Dialling a UK mobile phone in the us from the UK?
Dial +44 then the full UK number minus any leading zero.
Check your phone's instructions for how to enter the "+" character; it is normally found by holding or making multiple presses on the *, 0 or # keys, depending on manufacturer.
What is the bandwidth of CDMA mobile?
There are several possible answers to this question.
Various portions of the total electromagnetic spectrum have been set aside for mobile communications, each with an allocated bandwidth, typically quite large.
Some idea of the complexity of the allocation of the total spectrum and its size may be seen by viewing the following chart:
www.ntia.doc.gov/osmhome/allochrt.pdf
Conversely, there is an allocated bandwidth for each individual carrier for each type of service, and there are many types of service.
A comprehensive list of device bandwidths may be found at:
http://en.wikipedia.org/wiki/List_of_device_bandwidths
That list actually gives data rates, which are not the same as the bandwidth or spectral occupancy of the radio carrier in use. The actual bandwidth depends on data rate, modulation technique, coding, filter rolloff, access method, and guardbands. If you have a particular service in mind, I may be able to calculate the bandwidth for you.
How do you tell if your guyfriend likes you over texting?
start it off with maybe a question. something like "so do you like anyone?" if he says i don't know or no then back off..but if he says yes say something maybe like me to haha! and then say so who do you like? and if he tells you and it happens to be you be like well that's a coincedince i feel the same way..but if he names someone else then be like i have a few people on my mind. then change the subject or stop texting him. don't say anything like i like you so much...coming on to strong is to much to soon. take things slow and things will unfold just the way they are supposed too. :)

How would life be without cell phone?
Our life would be very difficult without mobile phones. Nowadays, most of work is done through mobile phones like online billing, browsing, finding route map etc. As mobile phone combined with internet is a boon to us thereby our lifestyle also improves and complex work gets more easier by using it.
Are you charged for incoming calls on a cell phone?
You should never be charged for an incoming call - no matter what service you use. The only time you should be billed for an incoming call - is if the other person reversed the charge via the operator (collect call)
It was definitely Ernie Wise.
There are many opinions as to what is killing off bees, and there are some people who believe cell phones are to blame. But no scientific study as of 2016 has shown this to be true. Here are some other opinions:
- The root cause of the recent bee die-off was an organism that killed the bees.
- It isn't certain why the bees are experiencing Colony Collapse Disorder. Cell Phone radiation could be the problem.
- We don't know for certain what is killing bees off (apart from a cocktail of viruses (many transported by mites), pesticides, poor variety of forage, dubious bee-keeping practices, hunger etc). There are things, however, that are exceptionally unlikely to be killing them off... and cell phones are on that list. There is absolutely no evidence to suggest that cell phones have any effect whatsoever on honey bee mortality. The only "study" that I am aware of was of highly dubious quality, done with a base station of a house "hands free" phone. Insufficient replication and no proper controls.
- To speak in absolutes about this would be choosing to remain ignorant of possible causes regarding the detriment bees are in fact experiencing. Though plausible and in some cases established reasons for bee CCD have been mentioned in the previous writings, they are sadly bias. The theory that radiation emitted from cell phone towers effects the navigational systems in worker-bees causing them not to return to their hives has been established as a viable theory. German research has shown that bees navigational systems are effected by power lines. This, in conjunction with local reports of CCD occurring near newly constructed cellphone towers led researchers to further look into the effect of the towers.
- Anything showing evidence of effecting bees should not be casually nor adamantly dismissed. Bees are VERY IMPORTANT to the planet and ALL of its inhabitants.
- Its not so much the cell phone itself as the radiation from the cell phone towers. Bees started suffering colony collapse around the time the cell towers were erected about 1994. As more and more towers are erected and the radiation levels increase then we see a more dramatic collapse as in recent years.
- In essence the radiation damages the immune system of the bees (as it does all living matter) thus rendering them unable to fight off other disease and parasite infestations.
- The radiation also interferes with the bees navigation and communication so they can get lost and fail to return to the hive.
- A research paper was presented at the Royal Society, London, in September 2008 detailing the evidence and explaining how the bees navigate using the earth's natural magnetic field.

How to tansfer all info from old cell phone to new cell phone?
Usually, the service provider will offer an upgrade when you are eligible. They will handle everything for you and guide you through the whole process.
However, there are some cases when the service providers do not notify you.
If they don't notify you:
Transfer your SIM card from your new phone to your old. Call your service provider if that doesn't work.
How do you send photo from cell phone to a email address?
Some base model camera phones have no web/email access and cannot directly transmit pictures to an email address. In this case, you can text/pic message to a phone that does have this capability and email from there.

When was the digital cell phone invented?
The first cell phone was made by Bell labs in 1947, but the idea began in the 1920's with police radios. The invention of the cell is actually given to Dr. Martin Cooper of Motorola in 1974. The phones were for government use and it wasn't until 1984 that the first sale of cell phones was offered to the public. The early phones were large, heavy and copied land line phones in style. They were carried in a zippered bag with a large battery in the bottom. In 1991 the digital cell phone was introduced.
