3G Technology

Market analysts are faced withrepparttar challenge of accurately predicting how much technology consumers will actually be willing to pay for 3G services. With 3G providing features that are ‘cool’ but expensive, and with cheaper and adequate alternatives available inrepparttar 143264 form of 2.5G,repparttar 143265 pure cell-phone features no longer hold any ‘pulling’ power. In fact, some critics argue that 2.5G speeds are just fine, thank you, and provide enough flexibility for most applications.

The rapid development of wireless LANs based onrepparttar 143266 802.11 standard andrepparttar 143267 future 802.11g standard means that 3G systems now have serious competition. Although Wi-Fi support is still patchy (and suffers fromrepparttar 143268 same security issues), and some users prefer 2.5G and 3G systems instead of Wi-Fi due torepparttar 143269 widespread coverage, wireless LANs have completely taken overrepparttar 143270 office environment. Not only that but wireless LAN systems are getting faster and becoming more robust. There are plans to develop 802.11 systems that approach 1.5 Mbps in theoretical speeds. Intel and others are also looking into developing metropolitan area networks (MANs) that expand that 300 feet Wi-Fi bubble to about 30 miles, or across an entire city.

Inrepparttar 143271 U.S, 3G services have been slow to start. Only in late 2003 and early this year did commercial 3G packages evolve torepparttar 143272 extent thatrepparttar 143273 general public became interested in them. Compare this withrepparttar 143274 presence of 3G services in Japan since 2001 andrepparttar 143275 popularity of 3G networks in Europe since 2000 (Finland launched it’s first network in late 2000). Compared torepparttar 143276 rest ofrepparttar 143277 developed world,repparttar 143278 U.S is lagging behind. And here is why:

A much more developed lower-tier communications infrastructure (2G and 2.5G) has meant that there are more alternatives have been available to consumers. ‘Wi-Fi’ has becomerepparttar 143279 latest rage with tech-savvy consumers, and because it became available before 3G systems were fully operational, it has captured a sizeable share ofrepparttar 143280 wireless business market. U.S companies have several technical and legal issues in acquiringrepparttar 143281 appropriate spectrum for 3G use fromrepparttar 143282 FCC. As technology becomes more sophisticated and bandwidth increases, systems become increasingly vulnerable to attack by malicious hackers (known as crackers) unless countermeasures are implemented to protect against such activity. Ensuring secure wireless connections in a pre-requisite to any wireless service provider.

Despiterepparttar 143283 obstacles, 3G is here to stay. The main issue is to work it intorepparttar 143284 market in such a way that it becomes useful forrepparttar 143285 majority of people, and not just a select few. Ideally, we are looking at multi-tiered services that offer a combination of 2.5G, 3G and Wi-Fi capabilities to one, national network. Eventually we would be using multiple networks to check our email, leave a message for a friend and download that bonus music video onto our PDA. Being part of a culture that revels on paying a flat rate for unlimited access, I would expect such a network to offer different levels of service, with customers being charged according to their service package, and not having to pay multiple fees for Wi-Fi and 3G access.

Just as PC users are starting to wonder whether there really is a need for faster computers,repparttar 143286 whole communications industry might also be entering a period of transition (not just a few years but perhaps a decade or two) where new technologies would not mean that older technologies become obsolete; rather, two separate consumer groups would emerge who would userepparttar 143287 old and new technologies side by side.

How to keep your postal mail private and secure

Written by Max Penn

Continued from page 1

HOW YOU SHOULD KEEP YOUR MAIL PRIVATE For security of personal correspondence I recommend double-wrapping your private letters, but with a bit of a change. Instead of sealing justrepparttar edges ofrepparttar 143181 inner envelope, i use clear sealing tape or clear packing tape.

1- Cut a lenght of tape twicerepparttar 143182 lenght of your inner envelope. Placerepparttar 143183 tape on a table, adhesive side up. You may need two strips of sealing/packing tape to coverrepparttar 143184 entire width ofrepparttar 143185 envelope (I was able to obtain 4-inch-wide packing tape, which works well forrepparttar 143186 smaller 3 5/8 x 6-inch personal correspondence envelopes, from a local moving company). 2- Now, after sealing your envelope, place it onrepparttar 143187 adhesive portion ofrepparttar 143188 tape and then foldrepparttar 143189 tape aroundrepparttar 143190 envelope so that it covers all surfaces.Leave a slight edge of tape aroundrepparttar 143191 envelope so that you can have an adhesive-toadhesive seal. This type of seal, covering all surfaces ofrepparttar 143192 envelope, is damn near impossible to get into in a surreptitious manner.

3- Now, placerepparttar 143193 sealed envelope in an out envelope and seal and address it normally.

The outer envelope doesn't stand out from other letters, but your private correspondence sealed inside is protected from snoops.

Evenrepparttar 143194 old tricks of using chemical sprays to makerepparttar 143195 envelope momentarily transparent won't work becauserepparttar 143196 inner envelope is completely wrapped in tape and therefore impenetrable by these sprays.
