1. What is Wifi VoIP Technology?
Wifi or wireless fidelity is the cure for the messy wired world we see every day in our office. Whatever we do, we always get tangled in the web of wires connecting one office equipment to another, such as computer desktops, printers, file drivers, DVD writers, and burners.
A typical Wifi network includes an Internet connection and a router device to manage and route access to this Internet connection. In this case, the router is Wifi-capable such that any Wifi device can wirelessly connect to the Internet within the area of about 200 feet or so of the radius.
This area is called a wireless hotspot. You could have heard of wireless hotspots in coffee shops or novelty stores. You pay for Wifi access to be able to use your Wifi-enabled laptop or Wifi phone at any point within the establishment. Wifi technology has many applications, such as peer-to-peer network connection, Internet access, gaming, and Voice over the Internet Protocol or VoIP. We suggest you use only the trusted provider for VoIP, and you can try to use the virtual phone number Hottelecom.
2. Wifi VoIP And Other Technologies
VoIP technology or Voice over the Internet Protocol, is the cost-saving routing of voice over the Internet. The conventional path through landline circuits was possible using a router device and VoIP application installed on the computer. This VoIP connection is prolonged and is prone to voice delay, jitters, and interference. Because of this, the previous VoIP service was not that popular with subscribers.
When wireless fidelity boomed, another option for VoIP connections appeared, which was called VoWifi or Voice over Wifi. As with other VoIP technologies, VoWifi uses virtual connections over licensed wireless frequencies. The Wifi standard operates from 2 to 5 MHz of the spectrum, with data rates fast enough to make VoWifi competitive in the market. Modifications on the wireless standard also led to a broader range of Wifi reach, resulting in more extensive coverage of Wifi VoIP services.
Aside from this Wifi access, VoIP is also possible through the legacy 3G networks, such as UMTS and EV-DO technologies, since 3G is riding on General Packet Radio Service or GPRS. GPRS is the technology that connects the average mobile phone to the Internet. It was the cause for mobile operators to start offering value-added services, or VAS, such as multimedia services, or MMS, and Internet browsing on top of the usual voice and text messaging services.
3. Getting High On Wifi VoIP
Wifi VoIP uses wireless frequency to complete VoIP calls. As with other VoIP technologies, Wifi VoIP is cheaper, and it maximizes the use of the wireless frequency resource. Not only does it result in a wireless environment, but it also provides an alternative option to the subscriber that results in a further decrease in service charges.
Wifi VoIP has number portability, while VoIP over 3G networks has none currently. Number portability is the capability of subscribers to retain their contact numbers at any point in the world. Using Wifi VoIP, subscribers can do this. For example, the VoIP provider, Skype, assigns an Internet number to its subscribers, and since the Internet is in virtual space, a subscriber can access Skype anywhere in the world and can still make calls.
Wifi VoIP is also faster in connection than VoIP over 3G networks. This is because Wifi technology is directly connected to the Internet while in a 3G network, a subscriber making a VoIP call must pass through the mobile network elements, such as the cellular base stations and subsystems, before finally connecting to the Internet.
There have been efforts to bring unity to both the Wifi and 3G networks. Mobile phone manufacturers have introduced dual-mode mobile handsets that aim to provide the subscriber with the maximum convenience. The subscriber can automatically transfer from one system to the other, an effective handover from Wifi to 3G and vice versa. Mobile phones such as the Nokia E60 and NEC N900iL were one of the first dual-mode phones.
4. The Need to Spot A Wireless Hotspot
Making a Wifi VoIP call is simple; go within the radar of a wireless hotspot. Hotspots are found within coffee shops, restaurants, train and bus stations, fuel stations, and even libraries.
In fact, in places where people are usually present, you will be able to find hotspots there. Wifi access for an Internet connection can be purchased using cash, credit, or debit card. There are many providers of this service, such as MyHotZone, Nomadix, SurfAndSip, and other such providers. For every Wifi VoIP call, the subscriber is charged accordingly by a VoIP provider, such as Skype, which means that the access charge for voice is different from the access charge for Internet access. There are Wifi phones in the market that are locked with Skype.
Is there free Wifi access? Yes, some hotels provide free Wifi services to their guests. There are other means to have free Wifi, but doing so will open the Wifi access to unauthorized users. There is a management system for hotspots in closed public networks wherein Wifi operators can provide free access in replace of paid advertisements.
4. Wifi VoIP In The Future
Wifi is a booming technology alongside with the current 3G technologies being implemented worldwide. Initially, Wifi was performed with laptop users in mind. However, improvements and advancements in technology are transforming it into a fierce competitor to beat by 3G technologies in carrying out voice services.
Technology-wise, the Wifi phone is more advanced in VoIP, but the legacy 3G networks offer more than just voice service. However, the fact that mobile phone manufacturers are making dual-mode phones means that 3G VoIP is lagging behind Wifi VoIP. The need of the market for VoIP influences the entry of dual-mode phones.
Presently, there are plans underway to convert several cities, such as Philadelphia, into a large mesh of wireless networks using Wifi technology. In this case, charging for Wifi access will be in the form of a subscription. At any point within the city, you can readily use your Wii-enabled laptop or Wifi phone without much of a problem. If the project pushes through, the subscriber will be able to make active VoIP calls via Wifi on every turn at a street corner.

6 Reasons You Should Have Security Cameras at Your Business
Implementing security cameras in business can Protecting your assets, ensure employee accountability, and provide evidence in legal matters

Today, more and more businesses are realizing the importance and value of video surveillance systems. Threats from both external and internal sources can be a constant worry for business owners, and peace of mind is scarce.
Having a robust video monitoring system like the one offered by Genetec will help you capture, store, and analyze video footage of everything that goes down on your premises. How will this help you in protecting what matters to you? Let’s find out.

1. Deterring Crime
First of all, video cameras are a natural deterrent for teenage scallywags and serious criminals alike.
If you have cameras visible on your property, anyone with ill intentions will understand that their risk of being caught out is that much higher, and they’ll naturally reconsider their actions.
In this sense, you may never need to use your video cameras for checking out any actual footage – if this is the case, you’ll know that they’ve done their job of preventing any incidents from happening in the first place.
2. Protecting Your Assets
Of course, as a business owner, there are things that are important to you. Whether it’s the property itself, equipment, inventory, or any other valuable assets, it’s important that you have an extra layer of security protecting them – especially if they might make your business a specific target.
Video surveillance is a much more practical and affordable option than having someone physically monitoring your assets 24/7.
3. Keeping Your Employees Accountable
Unfortunately, internal threats are a real thing, and many business owners have suffered at the hands of an “inside job.”
Data theft, physical theft, fraud, and other crimes have seriously impacted a large percentage of businesses, and small businesses are especially at risk.
Having surveillance cameras can help deter any issues of this nature and will further hold your employees accountable to do their jobs and maintain productivity levels.
4. Security Cameras in Business Reduced Insurance Costs
Business owners need to be constantly on the lookout for ways to reduce their costs and increase profit margins. One such way is to ensure you’re keeping your insurance premiums as low as possible – and having a great security system can help you do that.
The better protected your business is, the lower the risk is for incidents, and the less you’ll be charged for your insurance policy.
5. Evidence in Legal Matters
Many businesses will have to face a dispute at some point – between employees, between an employer and an employee, or even between employees and customers. In many cases, a lack of real evidence can make things complicated and even unjust.
Having security footage of your premises can provide important evidence for any disputes or legal matters that might arise, helping you to ensure that things are resolved efficiently and fairly.
6. Peace of Mind
Finally, remember that having peace of mind about the safety of your business, your assets, and your staff is priceless.
Video surveillance offers an extra layer of protection and security that will help you sleep easier at night, knowing that what matters to you is under protection and less at risk.
