Improve Your Business' Wireless Connection

The internet plays a huge role in companies today, from communication between branches to doing research on work. You just need the internet to go down for an afternoon to feel the power it has over a business. With wireless connections, it might not be your Internet Service Provider (ISP) that has gone down, but your PC might just be out of range, causing temporary disconnection.

There are various ways to improve a wireless connection to ensure that all PCs that are in range get 24-hour access. Speak to your ISP provider about improving your router and equipment. There are also other logistical steps that a company can take to improve connections.

The first practical option is placing your router in a central position. If you have an open office, using wireless is perfect. Place the router in the centre of the room, above the ground and away from walls and any type of metals or other disruptions. An example of a metal disruption would be filing cabinets.

Disruptions to wireless connections can be caused by cordless phones. It has been discovered that 2.4GHz cordless phones generally cause the most disruptions to wireless connections. Update to 5.8GHz or 900MHz and the problem should be solved.

If disruption is still an issue for your company, then try adjusting the channels on the router. Wireless networks can work on a range of frequencies, similar to a radio. You don't need to change the channel on the PCs using the wireless as they automatically adjust themselves.

If placing the router in a central location is not an option for you, then check the antenna. If you are sending signals to laptops that are fairly new, then you don't have to worry about this. Laptops that have been created in the last couple of years have built in antenna's that are strong and efficient. If you are connecting PCs, then check the antennae that you are using.

The standard antennae are omni-directional. This means they broadcast in all directions around the router. Speak to your ISP provider about a hi-gain antenna. This antenna sends signals in one direction only. Point the antenna in the direction where connection is needed the most.

If it is range that is causing the connection to go down, then ask your ISP company about getting a wireless repeater. A repeater can be placed at critical points between the access point and the PC. This will immediately strengthen your connection between these two points.

Wireless is fast becoming the most efficient way to connect to the internet. It has advanced from the old days when PCs used to huddle around the router. Technology has grown to the point where whole offices should be able to connect wirelessly for a reliable connection. If you are still having problems, then perhaps the best solution is to get an ISP that can assist you with getting what you need to run your company.

Choosing Broadband Services - A Guide For Businesses

With so many telecom services out there choosing the right one for your business can be challenging. Here is a guide to help you understand some of the main telecom choices that you have and what they mean to you.

The main types of lines available are T-1, DSL and OC circuits.

Generally speaking, faster speeds indicate larger bandwidth. The larger bandwidth is useful for large applications such as large data file transfers and streaming video. The large bandwidth also sets up your business to allow for future applications that may require additional bandwidth.

T1 - A high-speed digital connection that transmits data at a speed of 1.544Mbps. A T1 consists of 24 channels, which can be used for voice, data or a configuration of both. Each T1 can provide service for up to 50 to 100 phone users.

DSL - Digital subscriber line. A high-speed/broadband connection whose speed varies depending on the distance to the central office. The popularity of the DSL has been taken over by the T1. Unlike the T1, there are distance limitations. Cheaper than the T1, a DSL line is usually not covered by increased customer service like the T1.

T3 - A T3 is a high speed digital connection that transmits data at a speed of 43.232 megabits per second. The T3 is equivalent to 28 T1s. The T3 can handle even the most bandwidth intensive applications easily.

OC3 - Optical Carrier line that transmits at speeds up to 51.84 Mbps. The OC line uses optical fiber or SONET fiber optic to carry signals. The number behind the OC stands for the level of data transmission speed. An OC3 is equal to 84 T1s.

OC12 - An optical carrier line that transmits data at speeds of 622 megabits per second. This large bandwidth product is equal to 4 OC3's.

OC48 - A very large optical carrier that can transmit at speeds up to 2.5 gigabits per second. The OC48 is used for very large campus environments or as network backbones. The OC48 is equal to 4 OC12's.

How Much Bandwidth Does Your Business Need?

It doesn't matter what size your business is ... small, medium, or large. Having to determine how much bandwidth is needed for a new computer network, or upgrade of an existing one, is enough to make anyone break out in a cold sweat.

You can relax. Here's a simple guide to walk you through the minefield... and get you to the other side.

This should be approached from two angles - the first is to figure out where you are, and the second is where you need to go.

(1) Where you are - You need to have a sense of what you have now and how is it being utilized. Get an inventory of your current data and voice circuits. The monthly bills will give you a sense of call volume. You can ask your telecom provider for a report that will tell you max concurrent lines in use. This will be helpful to determine call volumes. For example if you have three PRIs, you may find that at times you have all channels in use at the same time. This could indicate capacity issues.

If you don't have any network monitoring in place, a tool like PRTG (cheap) or MRTG (free) can give you a sense of bandwidth and traffic type. Are people streaming videos all day long? Is it important for them to do so?

2) Where you're going - Once you get a handle of where you are, you need to understand what the business goals are for the next year or two. If they expect to add people, this means more capacity. If they want to improve sharing or data or extend systems across multiple locations, this may mean private networks. Adding more people? This means bandwidth and call volume may go up - especially if it is sales or customer support since they are one the phone more often.

As far as circuit selection, that is driven off what is available by providers in your area and how much does it cost for a term (12,24, 36 mo). Typically, you can get T1s just about anywhere, but you are limited to 1.5Mbps increments. This means you need more cards in your routers. After bonding 4-6 T1' it may be better to look at another circuit type. Check to see if ethernet/fast ethernet or fiber is available. These give you the most flexibility in increasing bandwidth as time goes on.

Based on circuit costs, I would not really go more than 36 months - 24 may be better. Also, go competitive bid if you can for services. If the LECs know you are looking for around, they will be more competitive in their pricing. If you'd like assistance with this just let us know....it's what we do. Plus our services are no cost.

Broadband - Unsure Future for the UK

Stephen Timms, the UK's minister for competitiveness, warned last year that the UK risks falling behind in the race to providing super-fast broadband networks, claiming the situation to be "21st century's equivalent of the great arms race".

Timms drew up comparisons between our current broadband networks to those used in Japan and Korea, the world's leaders in broadband speeds, questioning why the UK should be allowed to fall behind.

The average advertised speed in Japan was 93Mbps in 2007, and South Korea's 43Mbps. Compare this to the average advertised speed of 10Mbps in the UK, with actual download speeds in the region of 4.5Mbps its easy to see where Timms is coming from.

The answer, it would seem, to stepping up our broadband networks is easy enough - a nationwide roll-out of fibre optic networks. The practicability and cost factors involved with such a roll out however, are where businesses and government officials start to stumble.

With an estimated cost of 7 to 15Bn, Ofcom, the UK's telecommunications regulatory body is having a hard time trying to convince any one company to invest.

It's been raised that what Timms didn't take into consideration is the concentration of residence in Japan and South Korea, where network speeds are at their highest. As, once you move out of the big cities and into the vast rural areas, the situation with slow or no broadband access isn't all that dissimilar to that experienced here in the UK.

Realistically it would seem that there is no "quick-fix" solution to the problem.

Various experiments and trials are being commissioned around the country with regards to implementing fibre networks, which will of course help towards the cause.

Moreover, even though it does not compare to other countries' networks, the UK is expected to be able to have the networks in place to increase advertised broadband download rates to 24Mbps over the coming years; which is a considerable improvement based on current standards.
