The availability of the new iPhone from Apple makes this discussion especially relevant because it is almost a perfect realization of the 'Perfect Cellphone' with several exceptions.
Actually the iPhone offers no new hardware functions (maybe except the acceleramator,) but it does offer new attractive software functions such as 'multi-touch' and technology innovations such as the touch sensitive, large, bright, high pixel count screen and it is so beautifully packaged and supported.
This web log acknowledges that a cell phone that includes all the capability listed is probably impossible to package in an acceptably sized form factor, impossible to power within present battery technology, and impossible to price competitively.
And it is not clear that any single user of a cell phone would, in fact, want, or use all these features.
The best solution may be to provide as much function as possible via an SDIO (because its the smallest form factor) memory card or via web (server)-based functions. Aplle offers web-bsed functions and the new#G phone permits controlled native applications. But at the moment Apple has not yet decided to offer an external additional memory.
The format is to list a feature and then to identify, if any exists, examples of actual product availability as an indication of feasibility.
Any comments to this blog entry might describe a function and describe an implementation strategy that takes into account the cell phone form factor and power limitation.
The Functions of a 'Perfect Cell Phone:'
Wi-Fi and WiMax transmitters and receivers...Wi-Fi is available now, of course...iPhone has Wi-FIi but it is tied to AT&T subscription plans...jailed broke versions are available but its unclear whether Apple and AT&T will devise means to defeat the restrictions.
No hardware/software limitation to full use of the cellular high speed networks for internet access..... New 3G iPhone available in July, 2008 removes this restriction by providing web access via the 3g network.
Blue-tooth for wireless headphones and connection with other compatible bluetooth-enabled wireless devices (such as a door opener mechanism in automobiles..although I know of no such enabled auto door or house front door lock.)
Infrared for wireless exchange of electronic business cards etc
serve as modem for laptop...commonly available now
Serve as a wifi hot spot...see Joiku for S60-based phones as an example
voice recorder and telephone call voice recorder
5 mega pixel camera with auto flash and video and 6 X zoom and optical image stabilization
stereo speakers
speaker phone
e-mail... GMail, Yahoo, Hotmail, pushed from the mail server
good thumb keyboard or screen-based keyboard with hepatic feedback or good voice recognition.
quad band GSM and tri band CDMA...use anywhere in the world...
Samsung IP 830 w ...http://mobilitytoday.com/articles/sprint_ip830w_first_look.html
mp-3...iPod substitute..of course the iPhone manages this nicely.
FM radio...http://radio.about.com/cs/productreviews/a/aa102603a.htm
satellite radio...available via browser from Sirus web site with subscription
gps with map software...available via Compact Flash card: http://www.pocketgpsworld.com/item-menu.php?idSubCat=6
unlocked..not tied to a carrier..GSM ...just slip in an sim card (key to use around the world..`.need a carrier)
(Note: GPS satillite signal acquistion needs to be much speedier than current implementations...e.g., for personal use while walking or even for use in cars...the time to acquire is too long.
long battery life... see iPhone specs..but even using 3G and Wi-Fi at megabit transfer rates..battery operation for 24 hours
simultaneous voice call and Wi-Fi use (e.g., call using cell phone with speakerphone and web surfing at the same time)
software to decide whether a call is initiated using cell network or WiFi network depending on parameters set by user
voice recognition and voice command..maybe the best 'input' capabailty
remote TV control and door buzzer -opener...e.g., Novii Remote Blaster for Treo 650
enable Skype or other VOIP systems...
VGA out and presentation bundle (for projection presentations)
address book settings stored on server to enable population of next phone
can use cellphone disk drive as an auxiliary PC drive or as a mobile storage device
bar code reader for grocery stores etc..Treo SDIO Add-ons Barcode Socket OrganizeIT Suite for Treo 650/600
emotion language for SMS messages for illiterates...for use in Pakistan, for example, after the earthquake among illiterate populations.
VGA Plus (1078 x 790 pixels) screen
lose it alarm..when the phone is more than 10' away from a key chain fob, both buzz
stores car unlock and other tone controlled lock tones..probably requires Software Defined Radio (SDR) frequency chip because the cell radio, the wifi radio, the car door opener radio all use different frequencies...http://keyetv.com/consumer/local_story_097212459.html
dog collar radio transmitter...probably again a function of a software defined radio function
Remote 'bricking' of cellphone if lost irretrievably
cell phone front door lock opener ..see above..an SDR enabled fucntion
panic button...some implementation that enables quick unobtrusive calls to 911 but capability is not available to use by accident or by children
receiver for broadcasts in Museum or any area...again probably a function of a software defined radio
wireless laser pointer presenter
radar detector...an SDR receiver would be able to manage this.
Integration with GPS and auto memorization of radar traps...see Trapster
windows media player/ Quicktime Player for video surveillance applications...see WiLife.com
Air quality senor..touch finger to phone
blood sugar sensor..touch finger to phone
Pressure sensor to enable altitude and perhaps weather information applications... Read this!
reader for blind..brail reader via camera ...see Ray Kurzweil.
Recognition software for sign language...use video camera to capture and software to interpret the images into text for viewers which do not understand sign language.
