Is Your Internet Speed What You Anticipate?

Any client of a broadband company will say that their connection speed is in all likelihood the greatest part of the provision. However numerous broadband suppliers will not furnish you with tools to trial your speed. But there are many another sites available that will allow you to trial your internet speed. When testing your broadband speed it’s important to find a service that is custom-made to your nation, there is no point executing a trial employing a tester situated in England when you are trying to do a internet speed test in India.. A trial will hand you your upload speed as well as your download speed. Upload can be seen as speed betwixt your computer and the Internet, so should you post a lot of data files then upload is fundamental . Download speed is how fast you can receive files from the net to your PC. Download speed is ordinarily a lot speedier than upload speed and this is natural. Most individuals are much more occupied in their download speed instead of their upload speed as people commonly spend a good deal more time downloading. When you have discovered the speed of your internet service what do you do if you are not satisfied? The most self-explanatory option is to get in touch with your supplier and inform them that you have seen that your speed is less than it should be. You may also do things locally to make sure that your service is functioning as best it can. Always ensure that any domestic phone wiring is in quality shape and don’t employ bad quality lines. Verify your laptop virus software package is operational. When doing a internet speed trial always check that you aren’t executing any other actions that may be causing the supply to be utilized like playing games or downloading films.

Security, Stability, and Interoperability Issues on VoIP Implementation

Filed under: Internet Telecommunication Resources — admin @ 4:15 pm

Now we have accepted that VoIP is no longer just a phone service, it has become feature rich as it merges with computer configurations. The VoIP’s existence has changed considerably over the last few years, coupled with the availability of broadband connection to the Internet, plus leaps in multimedia technology in which virtual operations with remote sites becomes more enhanced, makes VoIP service a viable alternative to traditional communication offerings.

Cost savings is not the only driving force for VoIP implementations, enterprises have to consider some business aspects that VoIP can bring about. VoIP creates potentials for applications that could not have been done before. Collaboration, integration, and interactivity between employees and applications are one of the several business benefits that enterprises can derive from VoIP adoption. Nevertheless, amid euphoria of VoIP technology, there are three important aspects to look at before a company goes VoIP. In the following paragraphs I will summarize the aspect of security, stability, and interoperability that play a key role in the successful implementation of VoIP.

1. Security

VoIP implementations may expose new security risks and challenges that somehow become greater concern than quality and cost-efficiency among vendors and users. VoIP networks are vulnerable to all the same security risks as traditional IP data networks, including:

  • Denial of Service (DoS), viruses, worms,
  • Toll fraud and unauthorized access,
  • Spoofing, and port scanning.

It is recommended that organizations should adopt a layered, defense-in-depth security strategy to address the issue with the increasing proliferation of new Internet-borne attacks and malicious activities in recent years. In this architecture, the network is segmented into secure zones protected by layers of firewall, intrusion prevention, and other security services. This strategy allows the organizations to logically split and secure voice and data networks in front of individual voice and data components and between interactive points in the network.

2. Stability

One of the main issues of VoIP is the amount of bandwidth required for each call. There must be adequate bandwidth reserved and the quality of the link must be well maintained throughout each call to ensure the users are not affected. As the very nature of VoIP call is real-time, any disruption during the call would be easily noticeable and unacceptable. The two issues that enterprises usually have to deal with here are bandwidth and quality of service (QoS).

VoIP calls need a data transmission speed of 64kb/s to produce the quality of voice comparable to that of a normal telephone call. That 64kb/s channel needs to remain open and unaffected for the duration of the call. Theoretically, VoIP installations would not allow such a huge bandwidth to be allocated for VoIP alone. Therefore, there needs to be a compression taking place to compact the voice data into a considerable size before it gets transmitted over a packet switching network. G.723 codec that is incorporated in VoIP standard protocol H.232 can take a 64kb/s stream of data and squash it down to a mere 5.5kb/s or so. Generally, for VoIP to work reliably over WAN links, there has to be low jitter, low packet loss, a considerably high-speed connection between the endpoints, and less than 200ms delay.

3. Interoperability

Compatibility between VoIP equipment from different vendors is a very important aspect to boost the use of VoIP products. Without standardized quality of service mechanisms businesses would need to buy all the equipment and the QoS server from the same manufacturer. The VoIP world seems to be divided between many vendors with reluctance to establish interoperability and some who are trying to be end-to-end supplier but at the same time worried about interoperability. The protocols used in VoIP communication are still considered fairly complex in comparison to most of the other protocols involved in Internet applications. SIP (Session Initiation Protocol - a signaling protocol for Internet conferencing, telephony, events notification, and instant messaging), that is regarded as simple and elegant the other protocols, is still not efficient.

On the bright side, however, SIP is approaching status as an IETF (Internet Engineering Task Force) standard, after several years of work. With the recent version, it has achieved a greater amount of stability and changes are becoming smaller and smaller. Phone switch companies such as Nortel have recently begun supporting SIP, and now the manufacturers of handsets and related devices will soon ramp up their support. Motorola, Avaya, and Proxim have made collaboration on the creation and deployment of IP telephony solutions that will deliver new extents of communication mobility and network connectivity.

Finally, with these three VoIP aspects covered, businesses will be able to maximize their investment by applying it as the backbone of internal communication such as phone conversation, videoconferencing, instant messaging, faxing, etc. Another area that will widely make use of VoIP is call centers, in which Web contacts, virtual operations with outsourcers overseas, and remote sites, such as home agents, all could improve the customer experience. New VoIP applications that we have not thought about may also come into existence as the services generates more business and profits for companies.

When Hardware Fails, and Other Tech Problems

With electronic gizmos getting ever more complex, we’re ever more helpless when they breakdown. Fortunately, most failures end up being software bugs, so normally a patch can be downloaded from the internet and you’re sorted. However, sometimes failures are hardware failures. For instance, look at the XBOX 360 and how swamped the XBOX Support have been in attempting to deal with heat failures. When your hardware breaks, you can only send it back to be fixed. Do not attempt to fix the failure by yourself.

Unavoidably the early adopters of such breakthrough technology end up as the beta testers. It’s rather a smart move to resist the enticement of being amongst the first people to get a breakthrough gadget. The first in the queue will face higher prices, and experience more failures than individuals who hold off making a purchase.

If your games console - or mobile phone - or mp3 player - does produce a failure, look online and see if others have had a similar failure to you, and what they did to fix it. You can frequently save a lot of time of going through the same methods of trial and error. Frequently other people have located a specific number for Nokia help for instance.

New Module by Ericsson to Offer - Wake on Wireless

If you plan to buy a Dell, LG or Toshiba notebook later this year, chances are it will come geared with a mobile broadband module presently being developed by Ericsson, the Swedish telecom company. The module will enter the market in June this year and users can expect devices fitted with the module to be available by October.

The new module supports the Windows 7 operating system and is up to 50 per cent more power efficient then previous models. It also features a ‘wake on wireless’ feature, which could significantly enhance laptop security. The module will be able to connect to EDGE, GPRS and HSPA networks, giving a lot of freedom to the users in terms of network preference. For more info on mobile broadband and free laptops, click here.

Together with GPS technology, the wake on wireless system would allow users to track their machine if it were to be stolen. The system will also allow users to disable their laptops, as it will combine forces with Intel’s Anti theft PC protection technology. This means that users can activate the Anti-theft module by using mobile broadband and once the machine is disabled, it will be of no use to the thief. A similar deterrent system is already being used effectively for mobile phones.

Ericsson, which is playing a prominent role in the development of mobile broadband, is also currently occupied with a super fast 56Mb HSPA connectivity. A successful demonstration of the technology was recently made at the CTIA Wireless Exhibition in Las Vegas.

Boxing Gloves on, O2 to Enter the Laptop Market

It’s the New Year and O2 appear to be throwing out the old and bringing in the new. Well okay, that’s a bit of an exaggeration but what they are doing is having a revamp of around 150 of their stores and launching a major staff training drive. That can’t be a bad thing, it sounds like a promising start to the New Year.

Also in line with their revamp O2 are finally entering the arena and launching their own competition for the now ever so popular laptop and netbook market. O2 have staved off from entering and is now the last of the major UK networks to enter into the plethora of offerings for free laptop with broadband.

It has been reported that their approach to the competition maybe with a somewhat different strategy than their rival operators. Suggestions are O2 mobile broadband will not be offering laptops for free, but instead their offers will be laptops at a discounted price when bought as part of a mobile broadband contract.

So, now that all the major operators are now in the arena, its ding ding round one; all gloves on for competing for the largest proportion of the mobile broadband market.

VoIP - Save Money When You Talk

Filed under: Internet Telecommunication Resources — admin @ 3:00 am

VoIP offers many advantages to those who are brave enough to pull the plug. First, VoIP offers incredible savings for local, long distance, and international calls. It also offers great calling features for free that usually cost a fee when purchased with PSTN telephone services. Not only are people choosing to pull the plug from their telephones, but they are also embracing wireless technology as a whole.

With VoIP you can have the option of selecting your own phone number. In some cases, you can keep your current phone number. You will have to check with your VoIP provider and see what options they provide. However, many service providers do provide the opportunity of selecting your own area code. Some companies even have the choice of selecting area codes worldwide. This is a wonderful alternative for those who would like to choose an area code located where their family and friends are. For your unlimited calling plan, you can call your friends and family any time. But for those who are not on VoIP, they will thank you for giving them the choice of calling you on local rates.

VoIP operates in different forms. For instance, you can use VoIP when you use an Instant Messaging program with voice on your computer. These are very popular and now Yahoo, AOL, MSN, ICQ, and even Google have VoIP Instant Messaging programs. The benefits of these programs are that they are free to download off of the Internet and by using a microphone and your speakers; you can talk over the Internet with any of your buddies. As long as your friends and family members download the same program, you will be able to talk with them as long as you like and absolutely free. You can talk to anyone, anywhere in the world with VoIP Instant Messengers.

VoIP has proved that it offers great audio quality and is a perfect choice for meeting both residential and business telephony needs. As technology continues to advance, we can know that as we conduct our transactions over VoIP, the listener on the receiving end is hearing us with crystal clear audio clarity and that the future of VoIP will only have greater products readily available for its users.

Businesses also appreciate the ability to have integrated services. By combining audio, video, email and web-based applications, employees can better meet customer service needs and productivity again increases.

While many people are opting to go with VoIP, it still has some disadvantages. The main one is that it is hard to use 911 with VoIP. This is because the call is made from your computer network and not a landline phone. 911 will not be able to trace the phone call made from your VoIP phone and retrieve your address. Also, when you place your 911 calls, the dispatcher will not receive any of your location information. The FCC has issued rulings pertaining to this. Some options include registering with 911, when you call 911 giving them your information and location right away, or keeping a landline phone or cell phone available for use in case of an emergency. The latter may be the best solution for enjoying the best of both worlds.

To begin with, when purchasing VoIP services, you will be required to sign a statement that says you understand that your 911 services may be impaired by using VoIP. Some VoIP providers do not offer 911 services at all. Other providers will offer what is known as Enhanced 911. To use E-911 services, you may be required to first activate the 911 services. The most efficient way to use E-911 is to register your information with the Public Safety Answering system. They will take your name and physical address. That way, if you call 911, they won’t have your information readily available, but they will have it in their system. However, if you are out or away from your residence and call 911, your information will be useless. In a situation like that, you will need to clearly state your location. Your VoWiFi phone won’t reveal any of your local information, as a cellular phone will.

Enterprise VoIP

Filed under: Internet Telecommunication Resources — admin @ 1:11 am

Enterprise VoIP is making inroads among enterprises that cling to their circuit switched voice networks. The lure of Enterprise IP voice is having a single network to serve all modes of communication. Enterprise VoIP introduces efficiencies into the network, and allows for tighter integration

Enterprise VoIP is making inroads among enterprises that cling to their circuit switched voice networks. The lure of Enterprise IP voice is having a single network to serve all modes of communication. Enterprise VoIP introduces efficiencies into the network, and allows for tighter integration. Certainly from the supply side, we can see that Enterprise IP voice is taking off. Enterprise IP voice is still in the early stages of adoption, but is starting to move into the mainstream.

Awareness of Enterprise VoIP is winning over companies for its ease of use/manageability, flexibility and operational cost. Ease of use and manageability get high ratings because Enterprise IP voice equipment overcomes the hassle of performing mundane telecom tasks. For example, to change a user’s location within the building in a TDM world while maintaining the user’s current extension, physical changes would have to be made to the network. For companies that don’t have qualified staff, they need to pay for a service call. In an Enterprise IP world, user identity is coupled to the phone’s MAC address, and not to a particular port, so a user can simply pack their desk phone, plug it into the LAN port at the new desk, and be up and running. The convenience of Enterprise VoIP is a huge selling point.

Other drivers propelling Enterprise VoIP include scalability and the desire to consolidate voice and data networks. Implementing multiple wide area networks is expensive, and complexity increases as the number of networks and sites grows. Large organizations seek network convergence, and Enterprise VoIP is the way to get there.

Consumer adoption of VoIP services may also spill over into the enterprise VoIP world, as was the case with wireless LANs. Once people get used to advanced features available at home–for example, visual voicemail–they may end up pushing for the same capabilities of Enterprise VoIP at work. For companies that are deploying Enterprise IP voice, the advantages outweigh the barriers. The initial cost of deploying Enterprise VoIP technology are capital expenses. There are also some technical hurdles to adopting Enterprise VoIP although in the long run, the future of Enterprise VoIP is assured.
