Many devices that you already known and use take advantage of this frequency band. Garage door openers, baby monitors, and the next generation of mobile phones all use this frequency within the ISM band. Ensuring that Bluetooth and the other devices do not interfere with each other is a crucial part of the design process.

One of the ways Bluetooth will avoid interfering with other electronic devices is by sending out weak signals of around 1 mw. In comparison, even the most powerful of cell phones can transmit a signal of 3 watts.

The low power signals will limit the range of a Bluetooth device to around 32 feet, which cut the chances of interference between your computer and other electronic devices. Even though it has low power, Bluetooth does not require a line of sight between the communicating devices. The walls in your home will not stop the signal, making it great for rooms throughout the house.

Bluetooth can connect 8 devices at the same time. With each of those devices on the same radius, you may think they would interfere with each other, although it is very unlikely. Bluetooth utilizes a technique known as low frequency hopping, which makes it harder for more than one device to transmit on the same frequency at the same time.

With this technique, a device will use 79 individual, randomly chosen frequencies within a designated range, which change from one another

on a regular basis.

In the case of Bluetooth, the transmitters will change frequency 1,600 times or more every second, meaning that more devices can make full

use of the radio spectrum. Since every transmitter of Bluetooth will use spread spectrum automatically, it is very unlikely that two

transmitters will be on the same frequency at the exact same time.

When the Bluetooth devices come within close range of each other, an electronic conversation will occur to determine whether or not they have data to share or whether one needs to take total control. The user does not have any buttons to press or commands to give, as the conversation will occur automatically.

Once the conversation has occured, the devices will form a network. Bluetooth devices will create a PAN (Personal Area Network) or piconet that may fill a room. Once the piconet has been established, the devices will randomly hop in frequencies.

Bluetooth technology profiles will describe how the technology is used. Profiles can be best described as vertical slices through the protocol stack. It will define options in each protocol that are mandatory for the profile.

The profile will also define the parameter ranges for each protocol. The concept of the profile is used to decrease the risk of interoperability problems between the different products. These profiles will not normally define any additions to the Bluetooth specification, which is why you can add new profiles where you need them. The Bluetooth underlying technology is the same, only the specific method that it’s used is defined.

Generally speaking, all profiles of Bluetooth are based on the GAP (Generic Access Profile). There are many profiles that fall in the GAP category.

a) AVRCP, Audio/Video Remote Control Profile

b) ESDP, Extended Service Discovery Profile

c) CIP, Common ISDN Access Profile

d) PAN, Public Area Network Profile

e) HCRP, Hardcopy Cable Replacement Profile

f) GAVDP, Generic Audio/Visual Distribution Profile

g) A2DP, Advanced Audio Distribution Profile

h) VDP, Video Distribution Profile

i) HID, Human Interface Device Profile

To put it another way, usage models will describe Bluetooth device applications and the associated profiles that are used. The usage model focuses mainly on three categories; voice/data access points, peripheral interconnects, and PAN (Personal Area Networking).

The voice and data access points involve connecting computing devices to communicating devices through a wireless link. This way, data can be transferred in a wireless manor, without the need of cables or other types of connectivity.

PAN is another very important usage model with strong appeal to business customers. Bluetooth networks are easy to set up in virtually any type of environment. An example would be meeting others at a trade show.

Instead of having contact information beamed via infrared, business cards can quickly and easily be transferred via Bluetooth wireless. The fact is that many documents can be exchanged this very same way, making the uses and possibilities virtually endless.

The Bluetooth profile is very important to the specification, as it enables you to do so much more. You can use peripherals and devices with the profiles, and virtually anything else that you decide.

As Bluetooth expands and gets bigger and better, you can count on the profiles to expand and get even more functions. If you have experience with Bluetooth profiles, you should know exactly what they are and what you can do with them. If not, all you need is a Bluetooth device, and a vivid imagination.

Let It Ride Poker has originated from the Five-Card Stud Poker Game. This game gave gamers the choice of controlling two out of three bets. The players even have the option of pulling out their bets or “let it ride”. Let It Ride Poker is often compared to other games as Video Poker, Pai Gow Poker and Caribbean Stud Poker. All of these are mostly new derivations of the original characteristic game of Poker. The difference between let it ride and the others is that let it ride is a single-player game. This implies that the player is playing against the machine and not the other players.

Method of Playing Let It Ride

Let It Ride is a game that was started in 1993. A company called Shuffle Master Inc, which makes the automatic-shuffling machines, fashioned it. The game became a rage and it continues to maintain its popular status. A major reason for its popularity is that it provides immense scope for winning high stakes. The game is an offshoot of poker.

The aim is to gather a pair of 10s or more by using three cards given to the player and two “community” cards of the dealer. In addition, the nature of the game is such that the players are not competing against each other. All the players play against the house or the casino. This creates an atmosphere of friendship and fun. The rules are simple and the game can be learned quickly.

The basic steps to master the game are outlined:

1. Study how the poker hands are ranked.

2. Discover a Let It Ride table.

3. Purchase the chips or the tokens.

4. Set three equal wagers in the betting area.

5. Carefully scrutinize the cards that the dealer gives you.

6. You must now very carefully determine whether you want to take down your first bet or you want to let it ride.

7. If you choose to take the bet, take it down by signaling to the dealer.

8. If you choose to let it ride, then you must let it ride by brandishing your hand over the bet.

9. The dealer will then show one community card. Study the card.

10. Now repeat the earlier step. You must choose whether to take the second bet or to let it ride simply.

11. The dealer will again show a community card. Confirm whether you have a winning hand.

Postcards are rectangular card pieces that usually have a front panel that contains a picture and a back side with space intended for a short message, the mailing address and a stamp. These are meant to be mailed without envelopes. Direct mailing, on the other hand, is a service offered as a form of distribution wherein specific sample sizes are selected and sent as mails with advertisement contents.

Enterprising groups and individuals have resulted to tapping postcard printing and direct mailing to create a marketing strategy combination that’s both effective and economical.

When can you employ both strategies for marketing?

This depends on what you are offering and who you want to be involved. Are you selling a product, advertising a service or announcing an event? Are you targeting housewives, car owners or young members of the workforce? Once you establish answers for these questions, then it’s to know more about the basics of these two.

For what marketing purpose can I use both?

• New product or service

When you want to introduce a new item or service in the market, mass mailing postcards showcasing this can certainly create a wave of buzz. A picture, a short description and brightly colored letters for your product’s name all add up to a striking ad material.

Confident that a little of your product is enough to hook them up, include a return stub or a contact number that they can reach ask for free samples. You can also include promotional offerings such as raffles, with your postcards already pre-encoded with number permutations for the draw.

• Event Announcement

Another interesting use for these strategies is announcing big events such as trade fairs, exhibits, clearance sales, seminars, parties, movie premiers, product launchings and store openings.

Your postcards may serve as or contain the invitation to these events. A tear-ready stub on the postcard can be presented at the entrance with the rest of the postcard serving as a souvenir or, just its core purpose, as an ad campaign material.

• Information dissemination

If your aim is simply to spread information about you, your company or your product, postcards and direct mailing can do wonders.

If, for example, you’re a financial coach, you can send out postcards detailing your services, such as money management and investment planning. With customized postcards, it is even possible to include your business card on the postcard and that’s made detachable by perforations. These can then be mass mailed directly to your specified target clients like businessmen or retirees.

Launching your product to the market mainstream, publicizing an upcoming affair or shedding some more light on your merchandise or service – postcard printing and direct mailing will certainly help you save on marketing expenses since they cost less than ad productions, and TV or radio spots. They generate attention at the fraction of the price. Low-cost and target-specific, this duo opens possibilities to dynamic marketing techniques.

Comparative advantage is a concept used by economists to explain international trade. It suggests that even if a country has an absolute advantage in the production of all goods, it will maximize its wealth by specializing in those commodities in which it has the greatest advantage and trading for the others. For example, Martha Stewart may have an absolute advantage relative to just about everyone she could hire in cooking and cleaning. Should we then conclude that she should do the cooking and cleaning at home or should she outsource these activities? The answer clearly rests on the opportunity cost of her carrying out these tasks versus the cost of hiring someone else to do them. Her comparative advantage is likely in growing her business. Outsourcing is almost certainly the wealth maximizing strategy for Ms. Stewart.

In the context of our example, the opportunity cost of you carrying out the Administrative tasks yourself is the value of the time you will lose that you could have spent on other things, such as growing your business or spending time with your family and friends. There are only so many hours in a day. Let’s assume that you can make $150 dollars per hour for every hour you spend growing your business. The opportunity cost of you doing your own typing would be $600.00, whereas the cost of the Assistant doing the work (assuming an effective wage of $43.28 (calculations shown later)) is $259.68. Using the Assistant would result in a savings of over $340.00. Although your prospective Assistant would take 50% longer to complete the task, you would still be wise to maximize your wealth by spending your time growing your business. Despite the fact that you have an absolute advantage at typing, the Assistant has a comparative advantage (i.e. a lower cost) in carrying out administrative tasks. You should therefore, specialize in the task in which you have the greatest advantage.

Perhaps you’ve decided that you would profit by hiring an Administrative Assistant. But what about the other option, the Virtual Assistant? Hiring a VA couldn’t possibly be less expensive than hiring an Administrative Assistant, right? Wrong! According to Monster.ca, the median salary of an Administrative Assistant in Toronto is $42,837 per year. Assuming a 40 hour work week and a 52 week year, this employee would be paid for 2080 hours throughout the year at a rate of $20.60 per hour. This would seem quite reasonable but, according to a new survey by America Online and Salary.com, the average worker admits to wasting 2.09 hours per 8 hour workday on non-work related activities. So, assuming that an Administrative Assistant takes a 0.5 hour lunch and has 0.5 hours in break time, the work year turns into 1276.6 hours. This yields an effective hourly rate of $33.56.

Next we incorporate benefits. According to the Greater Toronto Marketing Alliance, the approximate total benefits paid by the average Ontario employer are 28.97%. This means the average Ontario employer pays $42,837 x 28.97% = $55,247 per year. This is an effective hourly rate of $43.28. This result would be even higher if we included the cost of office space and equipment.

As for the Virtual Assistant option, rates for VAs are usually between $20-45 per hour and can even be as much as $75 per hour for VAs that specializes in a particular field. The downside here is that although a VA is a qualified professional Administrative Assistant, he/she is also an entrepreneur and is therefore not available at your beck and call. Nevertheless, in working with a Virtual Assistant, you would pay only for the time spent on task and you have the added benefits that you don’t need to buy any office furniture and equipment, pay any benefits or allocate any extra space. It would seem likely at an early stage of a business’ lifecycle, if the administrative tasks are not sufficient to warrant hiring a full time employee, the best solution would be a Virtual Assistant. Indeed even if the workload justifies a full time employee the calculations above might suggest the VA route should be considered.

The choice is ultimately yours. If you can’t bring yourself to let go of even the smallest of tasks, you might be more comfortable continuing to do everything yourself. But, if you have decided you need help, your next decision should be whether to hire an Employee or use the services of a qualified Virtual Assistant. Carefully measure the benefits and cost involved with both options. Hopefully this article will allow you to make an informed decision.
