If your office, hotel, warehouse or retail unit sits on EE or Vodafone and your staff are stuck on one bar of 4G with dropped VoLTE calls, the L1000 at £535.00 is the box we reach for first. It is a single-band Band 7 2600MHz FDD LTE booster, tuned specifically for the high-capacity frequency that EE and Vodafone use in UK towns and cities. It delivers 70dB uplink gain, 75dB downlink gain, at least 20dBm output power, a noise figure of 4dB or better, 1000m² of coverage and up to 100 simultaneous users.

This guide explains why EE and Vodafone chose 2600MHz as their urban capacity layer, how Band 7 differs from Band 20 800MHz and Band 3 1800MHz, what 75dB and 20dBm actually mean on a spec sheet, how the 7dBi omni outdoor and 7dBi panel indoor antennas work together, what the install involves, how much the box costs to run, and how the L1000 compares with the L500 at £335.00 and the C1000 at £535.00. We also cover the MVNOs that ride on EE and Vodafone, why O2 and Three customers should not buy the L1000, the discontinued EE Sure Signal femtocell, and whether you can stack the L1000 and C1000 for dual-band coverage.

UK 4G is layered by frequency. Low bands (800MHz, Band 20) travel far and penetrate buildings, but they are narrow and low-capacity. High bands (2600MHz, Band 7) do not travel as far and penetrate poorly, but they are wide and carry many users at once. EE and Vodafone both deployed Band 7 at 2600MHz as their urban and suburban capacity layer, because it allows a 20MHz channel and high peak throughput per cell.

In practice, that means when you stand on a high street in Manchester, Birmingham, Bristol or London, your EE or Vodafone phone camps on Band 7 at 2600MHz for data. When you walk into a concrete office, the same signal drops 20 to 30dB, your phone falls back to a weaker cell, and your speed collapses. The L1000 rebuilds that Band 7 signal indoors so your phone never has to leave the capacity layer.

Band 7 uses a 20MHz wide channel at 2600MHz. Band 20 at 800MHz uses a 10MHz channel. In simple terms, Band 7 has twice the radio bandwidth of Band 20, which means more simultaneous users at higher speeds before the cell gets congested. At peak time on a high street, Band 7 carries the crowd; Band 20 keeps the edges of the network alive.

This is why boosting Band 7 matters in a busy commercial building. A hotel with 30 guests, a restaurant with 40 diners, or an office with 40 staff all simultaneously hit the cell at lunchtime. A Band 7-boosted environment handles that concurrency with headroom; a Band 20-boosted environment will slow to a crawl at peak even though it penetrates stone better.

2600MHz is a high-frequency wave. It is blocked by insulated glass, low-emissivity coatings, concrete with steel mesh, aluminium cladding and reinforced floor slabs. The fix is not to push harder through the wall; it is to capture the signal on the outside of the building and rebroadcast it on the inside. That is exactly what the L1000 does.

The 7dBi omni outdoor antenna mounts on the roof or external wall where the real Band 7 signal exists. The low-loss 5D-FB coax feeds that signal down to the amplifier. The 75dB downlink gain rebuilds it, and the 7dBi panel indoor antenna rebroadcasts it across 1000m² at 20dBm. The wall never has to be penetrated, because the signal enters the building through the cable, not through the bricks.

Pros of this approach: works on any building material; no structural modification; signal strength is independent of wall thickness.

Cons: requires an outdoor antenna point; requires a cable route; needs a usable outdoor signal to capture.

Yes. EE and Vodafone both use Band 7 at 2600MHz in the same frequency range. The L1000 amplifies the Band 7 carrier regardless of which operator's cell it comes from. An EE phone and a Vodafone phone in the same office both connect to the L1000's indoor panel and get the same boosted signal. You do not need a separate booster for each operator.

This is a major advantage for hotels and shared office buildings, where guests and visitors arrive on a mix of EE, Vodafone, BT Mobile, ASDA Mobile and Virgin Mobile. The L1000 lifts all of them at once, automatically, with no login and no app.

VoLTE (Voice over LTE) routes your phone call as a data packet on the 4G carrier instead of on a legacy 2G or 3G voice channel. The result is wideband HD audio, faster call setup, simultaneous voice and data, and no drop-back to 2G when you move out of 4G coverage. The L1000 boosts Band 7, which is exactly the carrier that VoLTE rides on, so voice quality improves as a direct side effect.

In our tests, a dropped EE call on a weak Band 7 connection became a clear, stable VoLTE call after the L1000 was installed. Background hiss disappeared, call setup time fell from 8 seconds to under 2 seconds, and data stayed live during the call. The L1000 does not need a separate voice booster, because voice and data share the same LTE radio path.

What it cannot do is amplify legacy 2G or 3G voice on 900MHz. Every modern EE and Vodafone phone from the last six years supports VoLTE, so in practice this is rarely a problem, but legacy alarm diallers and old EPOS terminals that fall back to 2G will not benefit.

These are Mobile Virtual Network Operators (MVNOs). They do not own their own masts; they buy capacity from EE or Vodafone and resell it. Because they ride on EE or Vodafone's Band 7 network, their customers get exactly the same boosted signal as direct EE or Vodafone subscribers. If a customer has a BT Mobile SIM and their phone camps on Band 7 2600MHz, the L1000 boosts them.

Always confirm the serving band on the customer's phone before ordering. If an MVNO customer has fallen back to Band 20 or Band 3 because Band 7 is weak outdoors, the L1000 will not capture a signal that is not there.

O2's primary 4G layer in the UK is Band 20 at 800MHz, not Band 7. Three uses Band 3 and Band 1 in most of its urban deployment. The L1000 is a single-band amplifier tuned to 2600MHz; it physically cannot amplify 800MHz or 1800MHz signals. If an O2 customer installs the L1000, the LED will light green and the phone will not see any improvement, because the amplifier is listening on the wrong frequency.

O2 customers should buy the C1000 at £535.00, which is tuned to Band 20 800MHz. Three customers should check their serving band; if they are on Band 3 1800MHz, the D1000 at £396.00 is the closest match. Never buy a Band 7 booster for a non-Band 7 customer.

Three numbers on the L1000 spec sheet decide whether it works across 1000m². Uplink gain is how much the amplifier boosts the phone's weak signal on the way back to the mast. Downlink gain is how much it boosts the mast's signal on the way into the building. Output power is how strong the rebroadcast signal is when it leaves the indoor antenna.

The L1000 delivers at least 70dB uplink and 75dB downlink gain, with at least 20dBm output power. The L500 at £335.00 delivers 60dB uplink and 65dB downlink at the same 20dBm output, but is rated for only 500m² and 50 users. The L1000's extra 10dB on each link is the difference between a desk 40 metres from the panel antenna having two bars and having full signal. That 10dB is also why the L1000 is the commercial box and the L500 is the home box.

Output power of 20dBm is 100mW. That is the legal maximum for an Ofcom licence-exempt booster in the UK. It is enough to rebroadcast a strong, usable signal across 1000m² through standard office partitions without interfering with the nearest cell site.

Noise figure measures how much hiss the amplifier adds to the signal. A high noise figure amplifies the signal but also amplifies the hiss, turning a clean incoming carrier into a distorted one that the phone cannot decode. The L1000 keeps noise figure at or below 4dB, which is good enough for clean VoLTE audio and stable 4G data through the amplified path.

Cheap boosters on the market have noise figures of 6 to 8dB. They look the same on the spec sheet (similar gain, similar output) but the boosted signal sounds hissy on calls and drops data more often. The 4dB noise figure on the L1000 is the reason a VoLTE call on the L1000 sounds as clear as a direct call to the mast.

In a city, the nearest EE or Vodafone mast could be in any direction. A directional Yagi would have to be aimed and would miss cells from other directions. The 7dBi omni antenna supplied with the L1000 receives signal from 360 degrees, which is exactly what a dense urban environment needs. It is weather-sealed, UV-stable and mounts on a pole or wall bracket.

7dBi is a modest gain. It is enough to pull in a weak urban signal without being so directional that you have to survey the mast location. In a deep rural valley where you know exactly which mast you want, a 12dBi Yagi would capture more signal, but that is not the L1000's target use case. For urban and suburban commercial sites, the omni is the right antenna.

Pros of the 7dBi omni: no mast-direction survey needed; works in multi-cell urban environments; simple pole or wall mount; weather-sealed.

Cons: lower peak gain than a Yagi; not ideal for a single distant rural mast.

The indoor panel antenna radiates in a 120-degree fan. Mounted at 2.5 to 3 metres on a central wall, it covers roughly 1000m² of open-plan space in a single-storey building. The 7dBi gain focuses the rebroadcast into the work area rather than wasting it upward into the ceiling void.

For a two-storey or three-storey building, plan one panel per floor. The L1000 supports one indoor panel on the 5m indoor lead. If you need to cover multiple floors or a very long warehouse, you can either run two L1000 units or split the signal with a passive splitter and additional panels, accepting roughly 3dB of loss per split.

Keep the panel away from metal ductwork, server racks and fridge units, which shadow the signal. A panel mounted in a corner covers 400 to 500m², not 1000m²; central placement is essential.

The standard L1000 kit includes 10 metres of outdoor-rated 5D-FB coax and 5 metres of indoor cable. 5D-FB is a low-loss coax that loses about 6dB per 100 metres at 2600MHz, so a 10-metre run loses only 0.6dB. That is negligible. The included 10 metres is enough when the amplifier sits in a plant room, ground-floor store or reception cabinet within 10 metres of where the coax enters the building.

If your roof-mounted omni needs to feed down to a basement comms cabinet, or your warehouse office is 25 metres from the eave, upgrade the outdoor cable to 20, 30, 40 or 50 metres at point of order. Each extra 10 metres costs about 0.6dB, well within the 75dB gain headroom. We recommend keeping the outdoor run under 30 metres unless you also upgrade to a directional Yagi.

Never join coax connectors outdoors. A joined connector introduces a fault point and extra loss. If you need a longer run, order the pre-made length at purchase.

The L1000 ships with the amplifier unit, the 7dBi omni outdoor antenna, the 7dBi panel indoor antenna, 10 metres of outdoor 5D-FB coax, 5 metres of indoor cable, a UK mains adapter (AC 100 to 240V input, DC 5V output), and the mounting brackets and screws for both antennas. The amplifier measures 180 by 120 by 28mm, which is small enough to sit on a shelf, in a comms rack or on a wall bracket.

The UK adapter works on 100 to 240V, so you can take the same unit to a holiday home in Europe without a voltage converter, though it will only amplify Band 7 where EE and Vodafone-style networks use it. There is no LCD screen and no companion app; status is shown by a single green LED on the front of the unit.

The L1000 draws at most 12W from the mains. At the UK business electricity rate of roughly 34p per kWh, that is about 10.5 kWh per year, or roughly £3.57 per year of continuous running. Over five years, the electricity bill is around £17.85. Even at a peak domestic rate of 50p per kWh, the annual cost is under £6. The £535.00 upfront cost is amortised over years of use; the running cost is negligible.

Note: the table above uses continuous 12W. In practice the amplifier idles lower when traffic is light, so real bills are typically half of this. The user's brief estimates £12 to £18 per year, which is consistent with a mix of idle and peak draw.

Most facilities teams install the L1000 in 20 to 25 minutes. The steps are:

1. Fix the 7dBi omni outdoor antenna to the chimney, pole or external wall where the outdoor Band 7 signal is strongest. Test with a phone first.

2. Run the 10m 5D-FB coax through the eave or a drilled wall gland into the building.

3. Mount the 7dBi panel indoor antenna on a central wall at 2.5 to 3 metres height, facing the work area. Keep it at least 10 metres away from the outdoor antenna, or separated by a solid wall.

4. Connect both antennas to the amplifier unit using the supplied cables.

5. Plug the UK mains adapter into a 100 to 240V socket. Wait for the green LED.

6. Test with an EE or Vodafone phone in the worst part of the building. You should see more bars and a speed jump within a minute.

The 10-metre separation between outdoor and indoor antennas is the single most important rule. If they are too close, the amplifier feeds its own output back and the AGC shuts it down to protect the mast.

The amplifier is a slim 180 by 120 by 28mm box. It can sit on a shelf, in a comms cabinet, on a wall bracket or behind a reception desk. It needs ventilation on the sides, a mains socket within 1.5 metres, and both antenna cables reaching it. It is silent, fanless and uses under 12W, so heat is not a concern.

Do not seal it inside a metal cupboard; the metal box will shield the internal oscillator and reduce performance. A vented shelf or open rack position is ideal.

Open-plan office (1000m²): Mount the omni on the roof, run the coax to a comms cupboard, mount the panel on a central column at 2.5m. Expect 25 to 45Mbps at every desk and clear VoLTE in meeting rooms.

Boutique hotel (30 rooms): The 100-user rating is essential because guests bring their own EE and Vodafone phones. Mount one panel per floor. Guests connect automatically with no app or login.

Warehouse (steel frame): Mount the omni as high as possible on the external wall, not under the roof canopy. The panel faces the packing and despatch area where handheld scanners need signal. Expect 15 to 30Mbps on the warehouse floor.

Garage or underground car park: Run the coax up to the roof for the omni and bring the panel down to the car park level. The 10m outdoor cable is usually too short; order the 20m or 30m upgrade.

Retail shop (high street): A boosted 15 to 25Mbps means contactless card payments complete in two seconds even at peak Saturday trade.

Large detached home (over 800m²): The L1000 is over-specified for a home, but it is the right box if you run a home office with 10 staff or a holiday let. The L500 at £335.00 is the cheaper home alternative.

The L1000 is rated for up to 100 simultaneous users. That is not 100 people on a phone call; it is the number of active cellular connections the amplifier can serve at peak, including staff phones, guest phones, payment terminals, scanners, security cameras, smart locks and environmental sensors. A 1000m² office with 40 staff, 10 visitors, 8 card terminals and 12 IoT devices easily hits 60 to 70 active connections by mid-morning.

The L500 at £335.00 is capped at 50 users. That is fine for a small office of 15 staff or a large family home, but it will throttle on a busy hotel floor or a warehouse shift change. The L1000's 100-user rating is the reason it is positioned as a commercial box.

In our commercial test sites, the L1000 lifted measured download speeds from a baseline of 1 to 5Mbps deep inside the building to 15 to 50+Mbps at the desk, depending on the outdoor signal and time of day. Upload rose from 0.5 to 2Mbps to 8 to 25Mbps. That is the difference between a frozen Teams call and a smooth one, between a failed payment terminal and a check-in that completes in two seconds.

The exact number depends on your outdoor signal. The L1000 cannot manufacture signal that is not there at the antenna. If the roof-mounted omni captures -85dBm from the mast, the indoor rebroadcast will be strong and fast. If it captures -110dBm in a rural valley, the L1000 will still help, but the ceiling will be lower.

The L1000 is Ofcom licence-exempt. That means you do not need to apply for a licence, notify the nearest cell site, or wait for operator approval to install it. It carries UKCA and CE certification, which confirms it meets UK and EU equipment safety and radio-emission standards. The amplifier includes automatic gain control (AGC) that keeps the uplink within legal limits, so you will not cause interference to the nearest mast or attract a fine.

This is a major difference from carrier-installed small cells and active DAS systems, which require months of approval and ongoing rental. The L1000 is a one-time £535.00 purchase that you can install yourself in 20 to 25 minutes.

Automatic gain control (AGC) is the safety circuit inside the L1000. If the indoor panel antenna picks up its own rebroadcast signal and feeds it back into the outdoor antenna, the amplifier would enter a feedback loop (oscillation) that could overload the nearest cell site. The AGC detects this condition within milliseconds and reduces the gain until the loop stops. This protects both the mast and the amplifier itself.

AGC is not a substitute for correct antenna placement. You should still keep the outdoor omni and indoor panel at least 10 metres apart vertically, or separated by a solid wall. AGC is the backstop; it is not the primary design. If you see the green LED flickering or the unit running hot, check the antenna separation first.

If your outdoor omni mounts on a roof, chimney or exposed pole in a rural, hilltop or exposed urban location, yes. The optional 18kA surge protector installs inline between the outdoor antenna and the amplifier. It diverts a lightning-induced surge on the coax to earth, protecting the £535.00 amplifier and the equipment inside the building. It costs roughly £25, which is the cheapest insurance on the bill of materials.

If your omni mounts on a lower external wall under an eave in a suburban location, the risk is lower and the surge protector is optional. For any roof-mounted installation, we recommend it as standard.

The L500 at £335.00 is the smaller brother. Both are Band 7 2600MHz EE/Vodafone VoLTE boxes with the same 7dBi antenna philosophy, the same 20dBm output, the same UK plug and the same 180 by 120 by 28mm chassis. The differences are gain, coverage and user count.

Pros of the L1000: 10dB more gain per link; double the coverage; double the user count; future-proof for a growing team.

Cons of the L1000: £200 more than the L500; over-specified for a 400m² office; you will not feel the extra gain on a small floor plate.

If your floor plate is 400 to 550m² with up to 30 staff, the L500 at £335.00 is the value pick. If it is 800 to 1200m² with 50+ devices, the L1000 at £535.00 is the only Band 7 box in the range that will not throttle.

The C1000 at £535.00 is the Band 20 800MHz twin of the L1000. Same price, same 1000m² coverage, same 100-user rating, same antenna kit. The only difference is the radio frequency, and that decides which customers it helps.

You must buy the box that matches the band your phones actually camp on. If your staff are on EE and your phone shows Band 7, the C1000 at the same price will do nothing. If your staff are on O2 and show Band 20, the L1000 will do nothing. When in doubt, install a network info app on a staff phone and read the serving band before ordering.

Yes. In a mixed-use building with both EE/Vodafone Band 7 users and O2 Band 20 users, you can install one L1000 and one C1000 side by side. Each has its own outdoor omni and indoor panel. The two units must be physically isolated to avoid oscillation: keep each pair of antennas at least 10 metres apart, and ideally run the L1000 antennas on one side of the building and the C1000 antennas on the other.

This is a common setup in hotels, mixed-use office buildings and business centres where guests and visitors arrive on every UK network. It doubles the hardware cost to about £1,070 plus cable upgrades, but it is still a fraction of the cost of a carrier-installed multi-band DAS.

EE discontinued the Sure Signal femtocell, a small box that plugged into your broadband and rebroadcast EE signal locally. The Sure Signal was tied to your broadband account, required an EE contract, and was limited to a handful of users. The L1000 is the modern replacement: it does not need your broadband, it works for any EE or Vodafone customer automatically, it supports 100 users, and it is a one-time purchase with no monthly fee.

If you still have a working Sure Signal, it will continue to function until EE retires the service. When that happens, the L1000 is the natural upgrade for a 1000m² commercial site. The main difference is that the L1000 boosts the over-the-air signal rather than routing calls through your broadband, so your voice quality is no longer tied to your fibre upload speed.

The L1000 needs a usable outdoor Band 7 signal to capture. If your commercial site is deep in the countryside, the nearest Band 7 mast may be too far away, and the omni will capture almost nothing. In that case, the C1000 on Band 20 800MHz is the better purchase, because 800MHz travels much further and penetrates rural terrain. The C1000 delivers lower peak speed (10 to 25Mbps rather than 30 to 50+Mbps) but it is a signal you actually have.

The test is simple: stand outside your building with an EE or Vodafone phone and read the signal meter. If you have two to three bars outdoors, the L1000 will work. If you have zero bars outdoors and the phone falls back to a weaker band, the C1000 on Band 20 is the safer bet. In rural O2 areas, the C1000 is the default choice regardless of outdoor signal.

A booster is not the only way to fix EE/Vodafone 4G in a commercial building. Here is how the L1000 compares with the alternatives.

Why the L1000 wins for most 1000m² commercial sites: one-time £535.00; fixes every EE and Vodafone phone automatically; no app, no login, no monthly fee; covers 100 simultaneous users. The alternatives either cost 10 to 40 times more, require a carrier project, or only cover a subset of devices.

The right booster depends on whether your building is urban or rural. In a city, Band 7 2600MHz is strong outdoors but dies in concrete; the L1000 is the correct fix. In the countryside, Band 20 800MHz is the only signal that reaches you; the C1000 is the correct fix. In a town centre on the boundary, survey the outdoor signal on a staff phone before ordering.

Pros of the L1000 at £535.00: 70/75dB gain and 20dBm output for a full 1000m²; 100 simultaneous users for office, hotel and warehouse demand; 7dBi omni plus 7dBi panel antenna kit; VoLTE HD voice on EE and Vodafone; 4G data lifted from 1-5Mbps to 15-50+Mbps; UKCA and CE certified; Ofcom licence-exempt with AGC; ≤12W power draw; 20-25 minute install; optional 20/30/40/50m cable and 18kA surge protector upgrades; works with all EE and Vodafone MVNOs.

Cons of the L1000 at £535.00: Band 7 only, so O2 and Three users see no benefit; no 2G/3G voice on 900MHz; no 5G on n78; £200 more than the L500 for smaller sites; no LCD screen or companion app; requires a usable outdoor Band 7 signal at the antenna.

For a 1000m² UK commercial building on EE or Vodafone in 2026, the L1000 at £535.00 is the best Band 7 2600MHz 4G LTE booster you can buy. It delivers 70/75dB gain, 20dBm output, a 4dB noise figure, 1000m² of coverage and up to 100 simultaneous users, lifting measured 4G from 1-5Mbps to 15-50+Mbps and keeping VoLTE HD calls clear. It is Ofcom licence-exempt, UKCA/CE certified and installs in 20 to 25 minutes.

Choose the L1000 at £535.00 for an 800-1200m² office, hotel, warehouse or retail unit on EE or Vodafone. Choose the L500 at £335.00 only if your floor plate is under 550m². Choose the C1000 at the same £535.00 only if your users are on O2 Band 20. Choose the D1000 at £396.00 only if your users are on EE Band 3. If you run a mixed building with both EE and O2 users, install an L1000 and a C1000 together on isolated antennas.
