This is the most valuable and useful tool for web developers and SEO (search engine optimization) people. Understanding correct server status codes is required when working with the sites with many URL rewrites, specially when working with redirects. The redirect response codes such as HTTP 301 (Moved Permanently) are normally cached by the browsers. Therefore you cannot understand the correct server response without this kind of a tool.

This tool can also be used to retrieve the server response content too.

Telecom regulator excited by speed

Dialog switches 4G on

Dialog Axiata, announced the commencement of its 4th Generation LTE pilot Network in the Colombo. Picture shows Director General of the Telecommunications Regulator Commission of Sri Lanka (TRCSL) Anusha Pelpita, along with Dialog Axiata’s COO, Supun Weerasingha, officiating at a demonstration of LTE network capabilities.

The pilot network will initially cover several key zones within the city and is billed to be the first exposition of a 4th Generation LTE network in the South Asian region.

Director General of the Telecommunications Regulator Commission of Sri Lanka (TRCSL) Anusha Pelpita officiated at a demonstration of LTE network capabilities featuring the achievement of data speeds in excess of 100 MBps in indoor demonstration mode, and 40-50 MBps in outdoor mobile usage scenarios within the city.

Commenting on the company’s initiative to implement a 4G Pilot Network, Dr. Hans Wijayasuriya said, “Dialog is proud to have the opportunity of carrying out an LTE trial in Colombo city. Technology life cycles are shrinking with each successive generation of technology and we are committed to make our network infrastructure compatible with the very latest technology and to provide our customers with network capability on par with the most developed markets in the world. The progressive policies of the TRCSL have enabled Sri Lanka to lead the region in this respect. LTE implementations are still in a nascent stage in most markets with terminal (dongle) availability being significantly limited. However, as we have seen in the case of 2G as well as 3G-HSPA, terminal availability cycles are accelerating and there is no doubt that LTE will be a fore-runner among high speed broadband technologies in the years to come. Dialog will build on the learning from the pilot network, to leverage the strengths of LTE technology towards making 4th Generation broadband services available and affordable to our customers from across all parts of Sri Lanka”

Everything you needed to know about Dialog 4G

Retrieved form an interview with General Manager, International Business
& Mobile Broadband, Navin Pieris.

DB: What exactly is 4G?

NP: 4G stands for 4th generation and it is the successor to
2G and 3G standards. 4G enables much faster data rates and lower latency on
mobile devices and, therefore, provides a platform for real-time multimedia
content delivery. It will drive real-time applications such as telemedicine,
traffic applications, online multiuser gaming, movie streaming, etc..

DB: What does LTE mean?

NP: LTE stands for Long Term Evolution and it will have
excellent support for browsing, VOIP, roaming and other IP based services.
Theoretically, it can reach speeds up to 300 Mbps. However, practical speeds
will be less. Dialog has been able to demonstrate speeds above 100Mbps.

DB: How current is this technology?

NP: It is the next evolution of mobile data technology.
Therefore, it is very current, and can even be termed the future. Only
approximately 36 networks are tipped to be commercially live by 2012.

DB: What are the benefits of using 4G?

NP: The key aspects are speed, reduction in latency and the
simplification of roaming. Therefore, all applications will perform much better.
Together with new devices it will make work and play on the move much more
effective.

DB: In what parts of the country is this service available,
currently?

NP: LTE is not commercially available in Sri Lanka just yet.
There are a few challenges, such as necessary spectrum allocation, to be met.
Further, LTE device-availability and pricing have to improve before it is useful
to our customers. Currently, the trail network is available in key zones across
Colombo Fort, Colombo 2, 3 and 4, and Narahenpita.

DB: What are the hardware requirements? Are phones and
dongles that support 4G/LTE readily available at the moment?

NP: Device-availability is at the initial stage. Few device
vendors such as Samsung, Motorola, etc. have 4G devices. Other vendors have
announced plans for availability. However, the devices are expensive, currently,
but we expect the prices to fall rapidly with the maturing of the technology and
volume growth A word of caution, though: Most of these devices will support
multiple channels. However, it will be best to wait till the spectrums are
allocated in Sri Lanka to ascertain device-compatibility.

DB: Some customers might be concerned that Dialog will now
focus more on developing 4G and not pay too much attention to improving the
existing 3G service. What do you have to say to these customers?

NP: it is not one or the other. We continue to improve in
all areas when it comes to providing a quality 3G service. We have added over
300 access towers this year, and will continue to add. We’ve also added
additional internet capacity. Sometimes, during this process, customers may feel
a drop in speed or have a few challenges with connecting on to the network. This
will happen when new base stations are added and network optimization and tuning
are in progress. We are doing our best to minimise any disruption.

We have paid attention to feedback we get from our customers on Facebook and
through other channels. We have noted comments from the North and East for
additional coverage and improvements in quality. The incessant rains and the
unfortunate flooding pushed our plans back a bit. However, these requirements
will be addressed.

DB: What is the next step? Where do we go from here?

NP: I think improvement in quality of service is key. We
will be concentrating on building more capacity, making infrastructure
improvements, and making service improvements to meet the expectations of our
rapidly growing customer base.

World popular term GPRS stands for General Packet Radio Service. Dialog GPRS can be accessed via EDGE (less than 32 kbps), UMTS (384 kbps) or HSPA (up to 14.4 Mbps) depending on your handset’s capability.

Normally when you insert your SIM card to a new handset Dialog automatically detects your handset modal and sends you GPRS, MMS and MyTV settings automatically. But all phone models are not supported with this function. If so you can set up your handset to GPRS, MMS or MyTV manually.
