Nokia had been producing commercial and some military mobile 2 way radio technology since the 1960s. In May 2008, Nokia announced on their annual stockholder meeting that they want to shift to the Internet business as a whole. Nokia no longer wants to be seen as the telephone company. Google, Apple and Microsoft are not seen as natural competition for their new image but they are considered as major important players to deal with. Nokia 8820 Phone is better than other Nokia cell phone even though there is no diamond on it. It's more smooth, thin and simple. People prefer the simple one when they see more complex cell phones. The Nokia 8820 concept phone seems to have a nice elegant touch to its slim slider design and luminous keypad.
Why a Yagi vs. omni-directional antenna for cellular repeaters? Yagi antennas have roughly twice the gain of omni-directional cell phone antennas. Also, all of the Yagi antenna's gain is pointing in one direction and it's elements collect and hold the signal better, so it is more efficient. Therefore, more coax cable can be used with a Yagi antenna vs. an omni-directional antenna.
Do you know the easiest walkie talkies to hack in to a secure system? Steal the password taped to the computer screen at Ed's work station. Trust me, I see it every day. You know what else? Most people use the same password for every system they need to access.
If you and a group of family or friends are traveling by car, bring a walkie talkie wherever you go. Cell phones need to have a cell tower in order to work properly. walkie talkie only need each other, making them more beneficial than the phones when you are traveling in rural areas that might not have cell phone coverage.
Bring cards. You can play many games with a simple deck of cards. They can even be a deck that is missing cards. Young kids don't know/care. Go fish, and war, and let the kids explore their wild side under controlled conditions.
Nokia 3720 classic is advised for extreme conditions, but sadly it is a phone with a limited shelf life. It protects itself from harsh situations and materials, except from those intentionally hammered at it. The call quality is excellent, perhaps better than phones categorized as 'normal'. Voices are clearly heard on both sides with no background hindrances. According to the Finnish company the battery life is as tough as the exterior providing up to 7 hours of continuous talk time and 19 days of stand by time.
There are some very tiny yet important distinctions differentiating regular Nokia phones from the 3720. It's the battery cover tightly held back with a screw so that dust or water doesn't trickle through. Similarly even the microUSB ports and audio jack are covered except for the radio communications charger port that remains exposed all the time.
One of the features that most people look for is touch screen capabilities. This is exactly what you will get with the phone. You can touch, tap, and drag on the phone's display. This will give you yet another 2 way radio to go through the functions of the heavy-duty mobile phone.
